Your research only shows the ships which are easily obtainable from the Internet. I would not call Salamis a battlecruiser with her 43km/h only speed. Even the first BC the Invincible class could go as fast as 47km/h. There are quite a few never were designs and proposals for Greece: Armstrong destroyer designs 342,43,47 from 1903 Armstrong destroyer design 725 from 1912 Ansaldo Armoured cruiser design, an improved Georgios Averoff or a further improved Pisa class from 1907 Armstrong armoured cruiser design 585 from 1908 DNC heavy cruiser / big gun cruiser proposal from 1939 Armstrong battlecruiser design 473 and an unnumbered one from 1906 Vickers coastal battleship design 509 from 1910 Armstrong battleship design 473A from 1906 Vickers battleship designs 375,76,80,81 from 1908 Armstrong battleship designs 724,24A,26,26A,27,27A,28,28A,29,30,31,31A.35,36,37,38,43 from 1911-12 Vickers battleship designs 545,46,47,48,59,60,63,65,66,67,68,69,70,93,94 from 1912 Armstrong battleship design 779 from 1913

Around the time of WW I, Japan conluded design studies of various warships apart from the usual sequence of design numbers like the A-46 through 57, A-110 through A-127 series of battleships and the similar battlecruiser series, there were also studies to what nowadays would call Super or Maximum battleships. These studies did not got numbers but rather alphabetical letters, from A through M. These studies are highly likely inspired or used as a basis for the Number 13 class (Hull number 13,14,15,16) class fast battleships or battlecruisers in the 1920's I've collected here the studies I've able to collect, and if data or drawing available post it. Currently I have information about the following alphabet studies: Design 'A','B','C','D','E','F','G','H','I','J','K','L','M' Their data: Displacement: 'A': 47.600t, 'B': 48.200t, 'C': 50.000t, 'D': 52.700t, 'E': 46.600t, 'F': 48.000t, 'G': 52.800t, 'H': 50.600t, 'I': 54.000t 'J': 50.000t, 'K': 49.000t, 'L': 56.500t, 'M': 57.200t Maximum Speed: 56km/h (30knots) for all of them Armour: Belt: 'A','B','C','D','E','F','G','H','I': 305mm, 'J': 279mm, 'K','L','M': 330mm Deck: 114mm for all of them except 'J' which had 102mm Armament: 'A': 5x2 41cm 16x1 14cm, 4x1 12cm AA 'B': 4x3 41cm 16x1 14cm, 4x1 12cm AA 'C': 2x3,2x2 41cm, 16x1 14cm, 4x1 12cm AA 'D': 6x2 41cm, 16x1 14cm, 4x1 12cm AA 'E': 3x4 41cm, 16x1 14cm, 4x1 12cm AA 'F': 2x4,2x2 41cm, 16x1 14cm, 4x1 12cm AA 'G': 2x4,3x2 41cm, 16x1 14cm, 4x1 12cm AA 'H': 3x4,1x2 41cm, 16x1 14cm, 4x1 12cm AA 'I': 4x4 41cm, 16x1 14cm, 4x1 12cm AA 'J': 4x4 41cm, 16x1 14cm, 4x1 12cm AA 'K': 4x2 46cm, 16x1 14cm, 4x1 12cm AA 'L': 5x2 46cm, 16x1 14cm, 4x1 12cm AA 'M': 4x3 46cm, 16x1 14cm, 4x1 12cm AA All of them had 8x1 61cm Torpedo tubes

And another reason I don't play WoW anymore. Their naming conventions are soo bad. The 4 Amagis were: IJN Amagi IJN Akagi IJN Atago IJN Takao Yes Ashitaka was first considered for the Takao but no IJN ship carried that name.

There was a design between Kawachi / Settsu and A-46 (Fuso preliminary) A 23.300ton design from 1907/08: 167,64(pp) x 173,74(wl) x 26,21 x 8,53m 23.300tons standard 28.000shp 4 shafts Steam Turbines 39km/h 7x2 30cm/45 Cannons 16x1 15cm/45 Guns 8x1 76mm/40 5x1 457mm Underwater torpedo tubes 279mm Belt, 44mm Slopes, 25mm Deck Basically an enlarged Kawachi with a superfiring pair of turrets forward with the rest the same. https://iiif.dl.itc.u-tokyo.ac.jp/repo/s/hiraga/document/61b73f5a-9012-4577-903d-fe87157e256d#?c=0&m=0&s=0&cv=0&xywh=-659%2C0%2C8261%2C4927

It's not my imagination the data tables clearly says it's dimensions, displacement, armament and arrangement. I've only draw her as I see it would had looked like

You can read some history in this article: https://warshipprojects.wordpress.com/2018/04/24/the-yamato-class-genesis/ But here are the actual designs: The first series: Yamato Preliminary Design A-140: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140-742537189 The largest, strongest, most heavily armed and armoured battleship ever to float the world oceans the Yamato class started it's design life as an even larger ship with a length close to 300meters, an all forward main gun arrangement but similar weaponry and armour. The Superstructure and the deck structures were different in this early phase of development but the tall pagoda style superstructure was evident which was later redesigned. This ship would had been a fast vessel with 57km/h (31knots) top speed, good range and excellent stability! Design choices can be seen here: to protect the AA guns both heavy and light as well as the the aircrafts, the main guns and secondary guns concentrated on the ends of the hull putting their blast effects far from these sensitive equipment. The aircrafts were stored in a protected hanger under the deck and behind the 155mm turrets with a ramp serving as an access to the catapults. The Light AA guns mounted high on the superstructure to provide clear arcs of fire as well as distance from the main guns blasts. Similar was the decision to put the boat storage under the hull but still outside of it at the aft parts and both sides of the main deck similarly on what was chosen for the Yamato, only difference is the size, as this was a larger ship the boat storage was much longer. While this was the very first design leading to the Yamato class, it was the only one to feature the 50 calibre 46cm cannons. After evaluating the design it was found (among other things) that the Arms industry of Japan could not produce such long barrelled guns hence the change to the 45 calibre one on the later designs. Other critical points were the large size both hull length and displacement wise as there were no docks capable holding the vessel for outfit, refit or repair works. I've choose fully enclosed 127mm gun turrets as to not protect them from blast effect (Though at extreme aft firing the 3rd turret's gun might effect them! ) but to protect them from light bombs and strafing fire of enemy aircraft. Angled funnel of the Yamato because all the boilers were located under the tower like pagoda superstructure with the turbines behind them. The design had the following characteristics: Dimensions: 294 (wl) x 41,2 x 10,4m Displacement: 69.500tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 57km/h (31knots) Range: 14.800km at 33km/h (8.000nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 6x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: i.imgur.com/zsBKwfN.jpg i.imgur.com/7QUJxvp.jpg Yamato Preliminary Design A-140A: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140A-744033811 After the very first Yamato design was born a slightly redesigned version was created designated A-140A. Shorter hull and reduced speed of a knot, but rather a turbine only propulsion, a mixed steam and diesel (COSAD if you like) was chosen which increased the range of the ship considerably by more than 2.000km or 1.200nm. Other than these changes the general layout of all the weaponry remained unchanged only they placed slightly closer to each other due to the reduced length of the hull The design had the following characteristics: Dimensions: 277 (wl) x 40,4 x 10,3m Displacement: 68.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 200.000shp, 4 shafts, Combined Steam Turbines (132.000shp) and Diesel engines (68.000shp) Speed: 56km/h (30knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: And drawing of the proposal: Yamato Preliminary Design A-140A1: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140A1-744589378 When the A subvariant of the A-140 design process finished, two further variants were made showing the effects and looks of different layouts of the weaponry. On variant A1 the 3 triple turrets were distributed in a classical way of two forward, one aft and secondary turrets adjusted accordingly to provide the broadside of at least 3 turrets. AA layout was changed resulting in a broadside of 6 turrets out of 8 which is superior to the previous 4 out of 8 layout. Otherwise hull size, engine power and type did not changed compared to the A design The design had the following characteristics: (same as Design A-140A) Dimensions: 277 (wl) x 40,4 x 10,3m Displacement: 68.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 200.000shp, 4 shafts, Combined Steam Turbines (132.000shp) and Diesel engines (68.000shp) Speed: 56km/h (30knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg And drawing of the proposal: http://i.imgur.com/O89LUI0.jpg Yamato Preliminary Design A-140A2: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140A2-745216267 On variant A2 the 3 triple turrets were changed to 4 twin ones distributed evenly forward and aft in superfiring pairs. While the firepower was reduced by a single barrel this layout allowed for a better firing pattern of the main guns making ranging shots much better than with 3 triple turrets. Compared to the A and A1 variants on A2 the AA layout was again changed with 3-3 twin gun mounts per side and the rest are located aft of the bridge and aft of aftermost superstructure resulting in an even better AA broadside or 10 guns out of 16 The design had the following characteristics: (same as Design A-140A) Dimensions: 277 (wl) x 40,4 x 10,3m Displacement: 68.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) Engines: 200.000shp, 4 shafts, Combined Steam Turbines (132.000shp) and Diesel engines (68.000shp) Speed: 56km/h (30knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 4x2 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg And drawing of the proposal: http://i.imgur.com/3rUVNbf.jpg Yamato Preliminary Design A-140B: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140B-745811009 While the very first Yamato preliminary the A-140 was a large and fast ship with an all steam turbine propulsion and the A variants were smaller and slightly slower designs with a mixed Diesel and Steam Turbine propulsion the B variants were even smaller and thus slower proposals but with a full Diesel propulsion system which seemed ideal for a Navy to travel long distances on the surface of the Pacific Ocean like the Imperial Japanese Navy. These designs were 30m shorter than the A variants but maintain the same armour, armament and general layout though the lack of a large funnel meant a considerable space could be allocated on the centreline thus the concentrated heavy AA weaponry there. The design had the following characteristics: Dimensions: 247 (wl) x 40,4 x 10,3m Displacement: 60.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 140.000shp, 4 shafts, Diesel engines Speed: 52km/h (28knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg i.imgur.com/1VtNLLL.jpg And drawing of the proposal: i.imgur.com/3rUVNbf.jpg Yamato Preliminary Design A-140B1: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140B1-746145207 Similar to the A-140A1 version, the B1 variant is the all diesel version of that proposals on the same shortened hull as on A-140B with the conventional layout of 2 main turrets forward, 1 aft, and the associated changes to the secondary 155mm armament as well as the 127mm heavy AA armament creating a compact looking battleship. The design had the following characteristics: (same as Design A-140B) Dimensions: 247 (wl) x 40,4 x 10,3m Displacement: 60.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 140.000shp, 4 shafts, Diesel engines Speed: 52km/h (28knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg And drawing of the proposal: i.imgur.com/QwxWHPK.jpg Yamato Preliminary Design A-140B2: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140B2-746278041 Like how the B1 version was the Diesel propelled smaller variant of the A-140A1, the B2 variant was the same all diesel smaller version of the A2 variant: 4 twin turrets distributed evenly forward and aft together with the changes in the secondary armament. AA layout is the same as on the plain B variant. The design had the following characteristics: (same as Design A-140B) Dimensions: 247 (wl) x 40,4 x 10,3m Displacement: 60.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 140.000shp, 4 shafts, Diesel engines Speed: 52km/h (28knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 4x2 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg And drawing of the proposal: http://i.imgur.com/QwxWHPK.jpg Yamato Preliminary Design A-140C: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140C-746759332 While for the previous designs there were sketch drawings I could use to make my drawings starting with the C variant I could only use others imaginations and ideas of how the various designs would look like. Except for the Design A-140 as I did not found a sketch for it as well only for A-140A. Now about the actual design. Version C is literally a copy of the plain B variant but with a reduced engine output and thus a slower speed. A true slow battleship though the saved weight was only 2.000tons due to the smaller engines installed. I've slightly changed the AA layout to look different and not as the same as the B version. The design had the following characteristics: Dimensions: 247 (wl) x 40,4 x 10,2m Displacement: 58.000tons (standard) Armour: 230mm Deck, 430mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 105.000shp, 4 shafts, Diesel engines Speed: 48km/h (26knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 46cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg Yamato Preliminary Design A-140D: https://www.deviantart.com/tzoli/art/Yamato-Preliminary-Design-A-140D-746763878 Similar to the C version, for the D version too I did not found any sketch drawings so I used my imagination and own ideas to make a unique design. Being as the same size as the B version with the same armament and engine power but 5000tons lighter and one knot faster meant a more efficient hull form must had been chosen by the designer hence I too choose a hull more similar to the Final Yamato design (A-140F6) than of those of the previous ones proposals. The same way I chose a different layout for the secondary and AA guns as well. Unlike to the previous versions on this design 41cm cannons were chosen as main armament rather 46cm/50 ones, and armour was reduced accordingly. The design had the following characteristics: Dimensions: 247 (wl) x 40,4 x 10,1m Displacement: 55.000tons (standard) Armour: 200mm Deck, 380mm Belt (Immunity against own 46cm shells between 20.0000 and 30.000m) inclined to 25 degrees Engines: 140.000shp, 4 shafts, Diesel engines Speed: 54km/h (29knots) Range: 17.000km at 33km/h (9.200nm at 18knots) Armaments: 3x3 41cm/50 Type 94 Cannons, 4x3 15,5cm/60 Type 90 Guns 8x2 127mm/40 Type 89 DP-AA guns 8x2 25mm/60 Type 96 AA Guns 6x Seaplanes (I choose Nakajima E8N Dave and Aichi E10A Hank planes) Data table showing the various variants: http://i.imgur.com/zsBKwfN.jpg http://i.imgur.com/GUdpUUa.jpg http://i.imgur.com/7QUJxvp.jpg http://i.imgur.com/3uEULbm.jpg http://i.imgur.com/1VtNLLL.jpg

And the final 35.000ton versions: Design A: https://www.deviantart.com/tzoli/art/Kongo-Replacement-Design-35K-Variant-A-809295225 Design B: https://www.deviantart.com/tzoli/art/Kongo-Replacement-Design-35K-Variant-B-809419491 Design C: https://www.deviantart.com/tzoli/art/Kongo-Replacement-Design-35K-Variant-C-809547068 Final Design X: https://www.deviantart.com/tzoli/art/Final-Kongo-Replacement-35K-Design-X-809674819

As the 1930 1st London Naval Treaty discussions are about the begin, Japan started designing new warships to replace it's old ships according to the 1922 Washington Naval Treaty articles. Two class were considered to be replaced: Fuso and Kongo each with 2-2 new ships. The ships would have good speed and well armed with new 41cm cannons with a displacement around 30-35.000tons. The overall look would be similar to the Yamato and her preliminaries. Yuzuru Hiraga made a proposals for the Kongo replacement while Kikou Fujimoto for the Fuso replacement. In this thread I post the Kongo replacement design. To made up for the tonnage the WNT allowed, Hiraga proposed multiple variants of weapon layouts and displacements for the IJN: - 35.000ton variants: a.: 3x3 41cm, Speed: 48km/h (26knots) b.: 2x4,1x2 41cm, Speed: 48km/h (26knots) c.: 3x4 41cm, Speed: 43km/h (23knots) - 30.000ton variants: a.: 2x4 41cm, Speed: 46km/h (25knots) b.: 2x3 41cm, Speed: 48km/h (26knots) c.: 3x2 41cm, Speed: 48km/h (26knots) d.: 2x4,1x2 36cm, Speed: 46km/h (25knots) e.: 3x3 36cm, Speed: 48km/h (26knots) - 25.000ton variants: a.: 2x2 41cm, Speed: 46km/h (25knots) b.: 3x3 36cm, Speed: 46km/h (25knots) c.: 4x2 36cm, Speed: 48km/h (26knots) - 20.000ton variants: a.: 2x3 36cm, Speed: 48km/h (26knots) b.: 3x3 30cm, Speed: 46km/h (25knots) Secondary armaments to be consisted of 152mm guns and AA armament of 120mm ones. The AA guns on the superstructure later appeared in some phases on the Yamato preliminaries. The final design however evolved from the 35.000ton B variant but instead of quad turrets it used triple to save weight and used 4 turrets instead of 3. The ship is very compact to further decrease the displacement and armour area. Note the use of both turreted and casemated secondary guns to save weight. On the other hand Fujimoto's proposal was much less compact lack casemate guns and had a more general look on the superstructure shape. Available data on the final design from 1928-29: Dimensions: 232m x 32m x 9mDisplacement: 35.000tons standard, 39.200tons full loadEngine Power: 160.000shp 4 shaftsMaximum Speed: 49km/h (26,5knots) Armour: UnknwonArmaments:2x3,2,2 410mm Cannons 4x2,8x1 152mm Guns in turrets and casemates4x2 120mm AA Guns2x1 610mm Torpedo tubes (probably submerged) 2x seaplanes Hiraga's proposal: Note the high angle secondary guns in the casemates as well! Fujimoto's proposal: Comparison: Note: It is possible that both Fujimoto's and Hiraga's designs are for the Kongo Replacement warships and not for Kongo and Fuso.

Yes that was 5 years ago. If you check the Japanese documents there are no designations so I have free reign however I want to designate them. http://gazo.dl.itc.u-tokyo.ac.jp/hiraga2/show/id/20680101#?c=0&m=0&s=0&cv=0&xywh=1103%2C-688%2C1777%2C3085&r=270 This time I went with increasing calibre.

Check the DA links there is all the info I could find. And don't use mobile phone for it.

Not sure if anyone cares for this on this forum, but here are the Kongo Replacement designs. First the 20.000ton versions: Version A: https://www.deviantart.com/tzoli/art/Kongo-Replacement-Design-20K-Variant-A-805798475 Version B: https://www.deviantart.com/tzoli/art/Kongo-Replacement-Design-20K-Variant-B-806186617

Still not working on the forums. I cannot search for users for example but some words do work like Yamato or Battleship.

Yes?

The drawing was made by me and for the 5th Yamato (My name for it is IJN Iki) The model is for an A-150 version with 51cm main turret is from a great modeller. I have different indeas for the A-150 (minimum of 8x 51cm cannons) with 3x2 that is most likely the Yamato upgun proposal: https://www.deviantart.com/tzoli/art/Yamato-class-Battleship-Upgun-Proposal-756260198 https://forum.worldofwarships.eu/topic/111061-the-yamato-class-preliminary-studies/ https://forum.worldofwarships.eu/topic/111349-the-a-150-super-yamato-variants/

That is a drawing made by TonyD, late warship enthusiast and artist. That is indeed his Own Design hence OD from like 15 years ago!. It was from his site: http://wolfsshipyard.com/ http://wolfsshipyard.com/Misc/WolfsDen/various.html http://wolfsshipyard.com/Misc/NeverWeres/royal.htm

As the title says: https://www.deviantart.com/tzoli/art/The-Mogami-Variants-600177319 These variants are: - Mogami class light cruisers as designed and laid down.- Mogami class light cruisers (IJN Mogami and Mikuma) as finished- Mogami class heavy cruisers (IJN Mogami and Mikuma) as refitted- Mogami class heavy cruiser IJN Suzuya as proposed for anti aircraft heavy cruiser conversion- Mogami class heavy cruiser IJN Kumano as proposed for anti aircraft cruiser conversion- Mogami class heavy cruiser IJN Mogami as rebuilt to aviation cruiser- Mogami class heavy cruisers as proposed to be rebuilt into light aircraft carriersNote how the aircrafts which was carried changed over time.More detailed info on the variants:First variant: After the sign of the First London Naval Treaty of 1930 Japan reached it's maximum allowed heavy cruiser tonnage by the completion of the 4 units of the Takao class and thus it had to cancel the following improved Takao class heavy cruisers. The tonnage limit for light cruisers too were very close to the set limit but by scrapping 4 pre-WW1 era protected crusiers of the Tone and Chikuma classes (3 ships), and replacement of the Tenryu class (2 ships) and the Kuma class (5 ships) by 1934 and 1937 allowed Japan to build 6 new light cruisers which then became the Mogami and Tone classes. Originally the Mogami class would displace only 8500tons standard but the requirements of the navy was so similar that of the 10.000ton Takaos that standard displacement risen to 9500tons and different weight saving measures had to be taken to reach this goal and thus Design C-37 was born.As the drawing illustrates the Mogami class as born was quite different from the ones actually finished. A bridge very similar to the Takao was adopted despite it's large mass resulting top heavy problems, large surface area for enemy fire and wind resistance counterweighted the positive points of centralised placements of fire-control, communications and navigational stations, the quadrupedal foremast was also taken from the Takao class. By reducing the boilers from 12 to 10 a single funnel could be adopted as well. A protected hanger was provided for the seaplanes which was almost identical to that of use on the Takaos. Main armament was chosen to be 15x 155mm guns in 5 triple turrets from the very beginning and because they are designed to provide AA fire, the secondary armament was chosen to be only 4 single guns but of new type (12,7cm Type 89). Torpedo armament and placement too was very similarly arranged that of the Takaos. Second variant: This is how Mogami and Mikuma was commissioned. After the Tomozoru incident of 14th of March, 1934 plans were created to fix the stability issues of the Mogami class (among other ships of the fleet as well). These plans (unofficially known as the first efficiency or stability improvement works) were completed in June of that year but the first two units were already launched while he other two just laid down. The plan included the strengthening of the transverse bulkheads, replacing the large Takao style bridge with a much smaller one cutting it's weight by 2/3rds, removal of the seaplane hanger and rework of the aft superstructure, reducing their weight by half. Various deck height reductions were included, as well as moving the torpedo tubes further aft, increase the AA guns to 4 twin from 4 single mounts, and reducing the number of boilers from 10 to 8 in the last two units: IJN Suzuya and IJN Kumano.Third variant: In 1937, following the denunciation of the 2nd London Naval Treaty of 1936 in the IJN decided to construct new ships and continue to modernize or refit the existing units, including the battlecruiser Hiei and light cruisers of the Mogami and Tone classes. While the barbette diameter of the Tone class was changed during construction there were no problems for them to fit the 20cm twin gun turrets used on the other cruisers but Mogamis was already finished by this time so construction new turrets postponed their refit. This refit (unofficially known as the third efficiency improvement or main gun replacement works) included the change of the 15,5cm triple turret to the 20cm twin ones, replacing the older Type 90 torpedoes with the newer Type 93 ones also known as Long Lances, replacing the seaplane catapult with a heavier and stronger one as well as torpedo-firing command station on top of the mainmast.Fourth variant: After the battle of Midway in which Mikuma sunk and Mogami was heavily damaged only 3 operational Mogami class cruisers remained in service. Between late 1942 and early 1943, while Mogami was underwent repair and conversion into an aviation cruiser to increase the fleet's scouting capability, plans were drawn up to convert both Suzuya and Kumano into Anti-aircraft cruisers. The plans included the replacement of all the main 20cm twin turrets to twin 12,7cm DP-AA mounts as well as increase of light AA gun armament. Though original plans included to convert both of the two fully operational cruisers to Anti-aircraft ships, most likely to wartime shortage of 12,7cm guns as well as suitable dockyard capacity, Suzuya would only got her aft guns replaced by the mentioned AA weaponry while still able to provide the same firepower as the Furutaka and Aoba classes.Sidenote: I've taken the liberty to add more MG director towers knowing the ship's changed purpose to AA instead of surface combat.Fifth variant: While IJN Suzuya would only got half the AA gun replacement that was proposed, IJN Kumano could had received the full conversion creating a potent AA platform rivalling even that of the USN's Atlanta class Anti-aircraft light cruisers. Other changes likely would be included the replacement of the main gun rangefinder with High-angle one as well as more Machine-gun director towers for controlled AA fire.Sixth variant: After the battle of Midway Mogami was heavily damaged and between late 1942 and early 1943, she underwent repair and conversion into an aviation cruiser to increase the fleet's scouting capability. This time the entire aft section of the ship rebuilt removing the both turrets (one was heavily damaged) and their ammo storage rooms was modified to hold gasoline, bombs and other ammunition. The aircraft deck extended to the stern with a rail system to move the designed complement of 11 Aichi E16A Zuiun floatplanes though at first she carried a mix of Mitsubishi F1M Pete and Aichi E13A Jake floatplanes. Her light AA armament also increased with associated directors as well. After the conversion was finished her main role as frontline combatant changed to a more supportive role to provide reconnaissance and scouting for the fleet with the ability to launch all her planes in roughly half an hour.Seventh variant: Shortly after the battle of Midway at the end of June 1942 proposals were made to quickly replace the carrier losses of this devastating battle. As no new fleet aircraft carrier to be excepted operational at least until 1944, conversion plans were made for all the cruisers and battleships of the Imperial Japanese Navy. Soon the Furutakas and Aobas were ruled out as considered too small and the Yamatos were not just new but too important for conversion. The conversion of the battleships (4 Kongo, 2 Ise, Fuso and Nagato) would take 18 months and would result in vessels with around 210-220m x 34m flight deck and an aircraft capacity of roughly 54 planes. In the end the Kongos were ruled out because with their high speed they could escort the carriers, while the Nagato's 410mm cannons were still considered a powerful armament, this lead to the decision of the Fuso and Ise classes with Hyuga's aft turret damaged this made the decision straight: Ise, Hyuga followed by Fuso and Yamashiro.As for the cruisers (4 Myoko, 4 Takao, 3 Mogami and 2 Tone), the conversions would took around 8 months to finish and would result in light carriers with 195-200m x 23,5m flight deck and an aircraft capacity of roughly 30 planes. In the end only the partially completed Ibuki was chosen to be finished as such a carrier, but even her was not finished in time.My drawing represent the Mogami class conversion into CVL, though I do not have any drawings of the plans I do have access to the Tone's similar conversion and the Ibuki from which I've created this.For those who are interested in the Tone class (IJN Chikuma to be precise) original sketch drawing showing her converted form, you can find it here:

This is the fourth and last part of my Royal Australian Navy Never Were designs with drawings. Here I post the modified Invincible design offered for the RAN Vickers Modified Invincible for Australia: https://www.deviantart.com/tzoli/art/Vickers-Modified-Invincible-for-Australia-777094768 Similar to Canada, Australia too modernised it's navy with American made equipment in the late 1960's and early 1970, replacing its de Havilland Sea Venom fighters with McDonnell Douglas A-4G Skyhawks and their Fairey Gannets with Grumman S-2G Trackers. During this time HMAS Sydney was not modernised, but provided an excellent platform as an LPH during the Vietnam War, while the replacement of Melbourne became a major political issue at the time. Since the mid 1970's the Navy looked at various proposals including a modified Invincible from Vickers of the Royal Navy, the Sea Control Ship design and the Iwo Jima Class of the USN and the Italian Giuseppe Garibaldi class of the Italian Navy, though probably more shipyards offered similar designs like the Spanish SECN (Sociedad Española de Construcción Naval) or the German Blohm + Voss shipyard's various MEKO designs. Eventually the Invincible design was discarded as it proved too expensive to build and the Iwo Jima class was preferred due to it's capability to easily modify to handle VSTOL aircraft and command facilities. I draw the Vicker's proposal, which as the sketch drawing shows would be very similar to the original Invincible though the most prominent changes were: a thinner superstructure, no GWS.30 Sea Dart missile launcher, slightly longer and larger flight deck and enlarged Hanger area to hold more aircrafts and helicopters. A few years later just before the outbreak of the Falklands Conflict the Royal Navy sought to reduce it's carrier force to only two ships and offered Invincible for sale to Australia, which they seriously considered and eventually accepted. The Australians considered removing the GWS.30 Sea Dart launcher as to not only create more deck space but because Australia already using the USN's Standard SAM system, maintaining two separate systems could not be affordable to them. These modifications might had result to the Invincible to look like as she was been in the early 2000's after her 2nd refit. But as the Falklands Conflict escalated the Royal Navy needed all her carriers resulting in Invincible sailed to the war zone and became the longest sailing on sea aircraft carrier of the Royal Navy on sea . After the war the Australian Government offered to release the UK from the sales contract if it wished. The offer was accepted, Invincible was retained by the RN and Melbourne was withdrawn from service in 1982 without replacement. In both cases, either the newly built Invincible design or HMS Invincible herself to be renamed in Australian service as HMAS Melbourne The design the following characteristics: (Same as the Invincible as built) Dimensions: 206,6 (oa) x 35 x 8,8m Displacement: Unknown, but probably close to 16.500tons (standard), 20.000tons (full load) Engines: 112.000shp, 2 shafts, COGAG (Combined Gas And Gas) Rolls-Royce Olympus TM-3B gas turbines Speed: 52km/h (28knots) Range: 13.000km at 22km/h (7.000nm at 12knots) Armaments: 2x7 30mm/77 Goalkeeper SGE-30 CIWS, Minimum 14x British Aerospace Sea Harriers and 4x Westland WG-13 Lynx helicopters in Hanger Sketch drawing: https://imgur.com/cBf2vPK Compare her to Invincible: https://imgur.com/jcaphMr Some more info can be found here: https://www.secretprojects.co.uk/forum/index.php/topic,23148.0.html

This is the third part of my Royal Australian Navy Never Were designs with drawings. Here I post the various heavy Cruiser designs offered to Australia, in the 1920's and also their own heavy cruiser design! Cockatoo Heavy Cruiser Proposal: https://www.deviantart.com/tzoli/art/Cockatoo-Heavy-Cruiser-Proposal-765349122 After the decommissioning of the battlecrusier HMAS Australia in 1921 and it's scuttle in 1924, the Australian Navy left only with WW1 era light cruisers and destroyers, nothing major to fight the ever increasing power of the Imperial Japanese Navy. Thus the RAN asked the Royal Navy, the Admiralty and Vickers to offer what could be built indigenously in Australia on 10.000tons. At first, plans of the Hawkins class was offered together with the new 8" gun turrets (The counties were still under development at this time) from this the Australians modified the hull to accept 3 triple or 4 twin turrets. 2 such cruisers would had been built at the Naval Dockyard at the Cockatoo Island near Sydney. From the original plans you can see that the cruiser is very much the same as the Hawkins class apart from it's enlarged size and different armament. Another unique element of this project was the usage of casemated 5" guns, meaning the Australians thought the 8" guns would not fire fast enough and required extra punch of which the quick firing guns would suffice.At this time Vickers offered modified versions of the County class heavy cruisers, later in 1926 and 1927 it offered modified designs of the Kent class cruisers. The designs had these characteristics: Dimensions: 179,83 (pp) 192 (oa) x 20,88 x 5,26m Displacement: 10.000tons (standard) Armour: 38mm Deck, 76mm Belt Engines: 90.000shp Parson Steam Turbines, 4 shafts Speed: 61km/h (33knots) Armaments: 3x3 8"/50 (203mm) BL Mk VIII Guns, 12x1 5"/51 (127mm) BL Mk VI Guns, 4x1 4"/45 (102mm) QF Mk V AA Guns, 4x1 533mm Below Water Torpedo Tubes Original drawing: Vickers Export Design 1074X for Australia: https://www.deviantart.com/tzoli/art/Vickers-Export-Design-1074X-for-Australia-766862849 This is one of the Vickers export designs offered to any nation who wished to acquire new ships but cannot built it's own. Design 1074X was the 3rd (to my knowledge) of the 1074 export series of heavy cruisers. 1074 was the same as this design in every aspect, probably the difference was the arrangement of engines and non-main armaments on 10.000tons and was probably offered to Spain among others. 1074C was the same hull but with only 4 twin 8" guns again on 10.000tons. 1074X the drawing you see is offered to Australia but it was probably offered to Japan as well is the same as plain 1074 but on 10.160tons. The hull is flush deck with a high forecastle and rising aft, not reminiscent of the Counties then under development but more of a mix between Hawkins (Long sleek lines) and the Counties (Flush Deck, ship size and engine arrangement). The original sketch drawing was rather empty so I have added a catapult with seaplane and County (York) type bridge structure. The designs had these characteristics: Dimensions: 179,83 (pp) 190,5 (wl) 191,72 (oa) x 19,5 x 5,33m Displacement: 10.160tons (standard) Armour: unknown but probably 25mm deck and belt over machinery and over magazines Engines: 115.000shp Parson Steam Turbines, 4 shafts Speed: 64km/h (34,5knots) Armaments: 3x3 8"/50 (203mm) BL Mk VIII Guns, 4x1 4,7"/43 (120mm) QF Mk VII DP-AA Guns, 2x4 12,7mm/60 MG Mk III AA Guns 4x3 622mm Torpedo Tubes 1x Supermarine Seagull Seaplane Based on this original sketch drawing found in the Yuzuru Hiraga archive: Vickers Export Design 1144 for Australia https://www.deviantart.com/tzoli/art/Vickers-Export-Design-1144-for-Australia-771753083 This is one of the Vickers export designs offered to any nation who wished to acquire new ships but cannot built it's own. Design 1144 was a modified County class (Kent group) heavy cruiser proposal with different engine layout (Most likely similar to that of the Hawkins), no Catapult and octuple 40mm Pom-pom AA guns to tart with offered to Australia but most likely to Japan as well in 1924. It has the same flush deck hull and 10.000tons as the counties and was a candidate for Australia to choose but instead the decided for a repeat County class of the Kent Group. On this design in place of the Catapult a command post was installed with centralised range finder equipment directors and seachlights. The designs had these characteristics: Dimensions: 179,83 (pp) 190,8 (wl) 191,72 (oa) x 20,8 x 4,95m Displacement: 10.000tons (standard) Armour: unknown but probably 38mm deck and belt over machinery and over magazines Engines: 80.000shp Parson Steam Turbines, 4 shafts Speed: 59km/h (32knots) Armaments: 4x2 8"/50 (203mm) BL Mk VIII Guns, 4x1 4"/45 (102mm) QF Mk V DP-AA Guns, 2x8 40mm/39 QF Mk VIII AA Guns 2x4 533mm Torpedo Tubes Based on this original sketch drawing found in the Yuzuru Hiraga archive: Vickers Export Design 1242 for Australia: https://www.deviantart.com/tzoli/art/Vickers-Export-Design-1242-for-Australia-775068720 This export design for Australia from Vickers is dated slightly later (In 1926 rather 1923 and 24) then the previous proposals and shows a modified York class Heavy cruiser with the same armament and layout but on a slightly different hull (75tons heavier, more than a meter longer and minimally narrower) Other then these it is basically a repeat York for the RAN. The designs had these characteristics: (IN brackets the York class) Dimensions: 166,11 (pp) 176,63 (oa) x 17,22 x 5,03m (164,6 (pp) 175,3 (oa) x 17,4 x 6,17m Displacement: 8.325tons (standard) (8.250tons (standard)) Armour: Unknown but probably same as the York so 38mm deck above machinery, 76mm above magazines and 76mm belt over machinery with 114mm over magazines Engines: Unknown but probably same as the York so 80.000shp Parson Steam Turbines, 4 shafts Speed: Unknown but probably close to 60km/h (32,5knots) Armaments: (Similar to York) 3x2 8"/50 (203mm) BL Mk VIII Guns, 4x1 4"/45 (102mm) QF Mk V DP-AA Guns, 2x8 40mm/39 QF Mk VIII AA Guns, 2x4 12,7mm MG Mk III AA Guns, 2x4 533mm Torpedo Tubes

This is the second part of my Royal Australian Navy Never Were designs with drawings. Here I post the Light Cruiser designs offered to Australia or partially developed by them: Modified HMAS Adelaide designs: https://www.deviantart.com/tzoli/art/Modified-HMAS-Adelaide-designs-764366890 After the 3 Melbourne (Town class, Chatham Group) class cruisers Australia received or built they prepared to lay down their 4th one the August of 1915. This time it was to be the newest type of the Town class: The Birmingham group, but the designers were asked for armament alternatives using 9,2in and 7,5in guns. Using the same weight as the original armament of these cruisers of 9x 6in guns the hull could accommodate 2x 9,2in or 3x 7,5in guns of which the first version was ruled out as two guns would not be enough for ranging. The designers were asked what could be done with 4x or 5x 7,5/45 BL Mk VI guns on a greater displacement with all guns on the centreline and with an ammo supply of 300 rounds rather 150 of standard practice as the ships would probably fight at a longer range. The designs would carry the same armour and range, though the machinery was to be enlarged to 27.500shp and a speed of 25,5knots were excepted which was helped by the lengthened hull of these two designs with the extra tonnage gained from the new guns and turrets as well as the longer armour belt. Official sketches show this kind of turret (yes, fully enclosed turrets) and funnel arrangements hence their layouts. Thus I've created these two drawings based on official DNC sketches though I've added 2x 40mm / 2pdr pom-pom and 2x 3" AA guns and used the Warrior's turrets as a basis for the main guns. The designs had these characteristics: Dimensions: 137,16 (pp) x 15,2 x 4,9m (141,73m on Variant B) Displacement: 5.754tons (standard), 6.540tons (full load) (6.118tons (standard), 7.000tons (full load) on Variant B) Armour: 19mm Deck, 76mm Belt Engines: 27.500shp Parson Steam Turbines, 2 shafts Speed: 47km/h (25,5knots) Range: 7.700km (4.160nm) Armaments: 4x1 7,5"/45 (190mm) BL Mk VI (5x1 on Variant B) 2x1 3"/45 (76mm) QF HA Mk II AA Gun 2x1 40mm/39 QF Mk II Pom-pom AA Gun 2x1 533mm Below Water Torpedo Tubes Compare it to Adelaide as finished in 1922: Dimensions: 131,06 (pp) 141 (oa) x 15,2 x 4,9m Displacement: 5.550tons (standard), 6.160tons (full load) Armour: 19mm Deck, 76mm Belt Engines: 25.500shp Parson Steam Turbines, 2 shafts Speed: 47km/h (25,5knots) Range: 7.700km (4.160nm) Armaments: 9x1 6"/45 (152mm) BL Mk XII Guns 1x1 3"/40 (76mm) QF Mk I AA Gun 2x1 533mm Below Water Torpedo Tubes Royal Australian Navy 1944 Design Light Cruiser: https://www.deviantart.com/tzoli/art/Royal-Australian-Navy-1944-Design-Light-Cruiser-761831373 This cruiser proposal dates back to 1943/44 to an imperial defence plan for Australia:“MP1049/5 2026/3/516 Cruiser and Destroyer Building Program”.The file begins in mid 1943, discussing the advisability of building cruisers and destroyers in Australia to replace war losses and the ageing remaining ships, and the file ends with the dispatch of the RA Eng and Director ordinance from the Naval Boards Melbourne office being ordered to London from June-Aug 1944 to consider current vessels under construction in Britain.Prior to this mission, the ACNB set out what it thought were the war lessons.A - Air Power – neither side seeks surface action in daylight without air support, so there are more night actions than day, and all ships require maximum AA fire power and ability to stand up to bomb and aerial torpedo damage.B - The destructive power of the modern torpedo.C - The ever increasing efficiency of radar.D - The devastating effect of high volume of fire at night ranges from medium calibre guns. and then the desirable features of an RAN future cruiser given the war lessons. A - Main armament dual purpose guns. The 5.25in gun appears to be the most satisfactory calibre for HA/LA (with “at present” added in pencil)B - Secondary armament guns more numerous than in present design 40mm guns are required in addition to 20mm.C - Side armour and deck armour.D - Improved under water protection. Large compartments should be partitioned by water tight bulkheads,E - Maximum speed 30-32 knots. Higher speeds are not considered necessary.F - Large endurance.The paper then considers a number of British designs, improved Southampton, Fiji, Dido.It selects the Dido as the most suitable based on its HA/LA armament, but with these weaknesses.A - Endurance much too small. (stated at 7500miles econ, 1,700 miles full speed)B - Too vulnerable to under water attack.C - Insufficient HA firepower abaft the beam.D - Insufficient medium and short range AA armament.E - Inability to engage more than two AA targets in primary control with main armament. They then outline a cruiser the authors think would be perfect for the RAN post war.Speed – 30 knotsEndurance – 10-12,000 miles at economical speed.Gun armament – 12-15 5.25 HA/LA, 12 or more 40mm bofors, 12 or more 20mm.Protection – Side and deck armour, improved watertight subdivision.Displacement – 8-9000 tonsLength 550-570ft Beam 60-65ft No aircraft. The author proposes no torpedoes, but the paper is edited by someone who finds them essential, and points out that doctrine is to “fix by gunfire, and sink by torpedo”.They propose the main slipway at Cockatoo Island built up from its present 450ft to 600ft. All designs, plans, skilled technical personnel etc to be sourced from GB.Imports would include: 80% of all steel (the right grades were not made in Australia – this was cited by the minister in the 1930’s as a reason not to order an Australian Leander).All armour plate. All armament, All fire control. 80% of auxiliary machinery. Forgings for main turbines. 60% of electrical cable. 80% of electrical equipment. Anchor cables. To be laid down in 1944 for completion in 1948, and to be followed by another 5 similar ships from 1944-1953, replacing entirely the wartime losses and pre war ships. The design the following characteristics: Dimensions: 167,64 (wl) 173,74 (oa) x 19,8m Displacement: 9.000tons (standard) Armour: 51mm Deck, 89mm Belt Engines: 4 shafts, Parson Steam Turbines, Unknown shp probably around 80.000shp Speed: 56km/h (30knots) Range: not sure but probably 22.000km (12.000nm) Armaments: 4x3 5,25"/50 (133mm) Mark IV Guns 6x2 40mm/56 Bofors Mk X AA Guns or 5-6x4 40mm/39 Pom-Pom Mark VIII AA guns, 8x2 20mm/70 Oerlikon AA Guns 2x4 533mm Torpedo Tubes I've based my drawing on the Crown Colony class light cruiser and the N2 design light cruiser.

This is the first part of my Royal Australian Navy Never Were designs with drawings. Here in part 1 you can see the smaller escort ships the Frigate and Light Destroyer proposals: Australian General Purpose Escort: https://www.deviantart.com/tzoli/art/Australian-General-Purpose-Escort-760010550 In the 1960's the Royal Australian Navy asked for a small sized, relatively cheap escort vessel to perform a wide range of peacetime and wartime missions, including Anti ship, Anti-Submarine and Anti-Air ones. For these missions the armament was relatively light but well balanced. The project was dropped due to the issues between missions of what the RAN required and what the RN designers proposed and in the end the Australians bought modified Charles F. Adams class Guided Missile Destroyers, the Perth class and a number of fast attack patrol crafts. Original design included full British weaponry but the Australians wanted American made missiles and guns, thus I've created this later variant. The design the following characteristics: Dimensions: 101,5 (wl) x 10,4 x 3,5m Displacement: 1.800tons (standard), 2.000tons (full load) Engines: 35.000shp, 2 shafts, CODOG (Combined Diesel Or Gas) Probably MAN diesel & General Electric LM2500-23 gas turbines. Speed: 69km/h (37knots) Range: 9.600-10.500km at 22km/h (5.200-5.700nm at 12knots) Armaments: 1x1 127mm/54 Mark 18 Gun 2x1 20mm/70 Oerlikon AA Guns, 1x8 RIM-7 Sea Sparrow Missiles, 2x3 324mm Torpedo Tubes 1x Bell UH-1 Iroquois helicopter I've based my drawing on this proposal: Australian Light Destroyer Project: https://www.deviantart.com/tzoli/art/Australian-Light-Destroyer-Project-760948911 Soon after the failure to order the General purpose escort of the early 1960's slightly later In 1964/66 the Royal Australian Navy started a design work for a light destroyer capable of defending it's shore waters from various hostile forces. The first designs showed a rather small sized vessel with two 5" guns one aft, one forward, and a helicopter deck of around 2000tons displacement barely larger than a frigate at the time. Over time the design evolved into a very capable destroyer with single 5" gun an RIM-66 Standard SAM, anti ship missiles and short range light AA guns. But like the previous programme the shifting requirements and poor project management by the Navy together with political pressure and increasing costs meant that these ships were never built and instead 4 (later another two home built) modified Oliver hazard Perry class Frigates were bought known as the Adelaide class. The design the following characteristics: Dimensions: 129,54 (wl), 137,16 (oa) x 14,6 x 6,7m Displacement: 4.20tons (standard), 5.000tons (full load) Engines: 50.000shp, 2 shafts, COGOG (Combined Gas Or Gas) Probably Rolls-Royce Olympus TM-3B & Tyne RM-1A gas turbines Speed: 56km/h (30knots) Range: 11.000km at 22km/h (5.900nm at 12knots) Armaments: 1x1 127mm/54 Mark 19 Gun, 2x2 30mm/75 Mark 28 AA Guns, (Commonly known as Emerlec EX-75) 1x1 RIM-66 RIM-66 Standard MR Missile launcher, 6-8x Anti ship missiles (probably RGM-84 Harpoon) 2x3 324mm Torpedo Tubes 2x Westland WG-13 Lynx helicopters More info can be found here: https://en.wikipedia.org/wiki/Australian_light_destroyer_project Based on these drawings: and model: http://www.shipmodels.info/mws_forum/viewtopic.php?f=67&t=54420

You can read some history in this article: https://warshipprojects.wordpress.com/2018/04/24/the-yamato-class-genesis/ These are my ideas of the follow up classes of the Yamato class battleships based on the very scarce information available about them as well as on ideas floating on the net and on logical assumptions about the previous classes and designs. Design A-150, possible variant A: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-A-756838933 Soon after the design work on the Yamato class battleships finished and the first ships launched preliminary work was started on what to build which would even surpass these gigantic vessels and with which the gun supremacy over the USN could be maintained within the Peace Goddesses doctrine. While the Yamatos were designed to carry triple 46cm gun turrets with the ability to swap them to twin 51cm ones, the new class should carry these weapons from the beginning. Details on this design is scarce, different sources tell different information, but what is common: 51cm armed main weaponry 10cm DP-AA guns Yamato like hull shape armour protection against own weaponry What differs among the sources are the number of these guns and the size of the vessel: possible 27 or 30knots speed 6-8-9 51cm cannons many but minimum 7-8 twin turrets per side of 10cm DP-AA guns 43-46cm belt armour This is one of my idea for the A-150 type battleships using the Yamato hull to mount 8 twin 51cm turrets and no secondary turrets. To provide more space for the main gun turrets as well as for the engines I've slightly moved the turrets forward and lengthened the entire superstructure by a few meters. My design has the following characteristics: Dimensions: 244 (pp) 256 (wl) 263 (oa) x 38,9 x 10,75m Displacement: 68.000tons (standard), 77.800tons (full load) Armour: 250mm Deck, 460mm Belt inclined at 20 degrees Engines: 165-170.000shp, 4 shafts, Steam Turbines Speed: 50km/h (27knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 4x2 51cm/45 Type 98 Cannons, 16x2 10cm/65 Type 98 DP-AA guns 12x2 40mm/60 Type 5 AA Guns 22x3 25mm/60 Type 96 AA Guns 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating) Type 32 surface search radars (two set one on each side of the bridge structure rotating ones) Design A-150, possible variant B: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-B-757683631 This is another possible version of the A-150 type battleships the IJN considered building after the Yamatos. Similar armament to the A version, but I've lengthened and widened the hull to put larger engines inside and to mount the two triple 15,5cm superfiring over the 2nd and 3rd 51cm twin turrets. This design of mine has the following characteristics: Dimensions: 268 (wl) 275 (oa) x 40,5 x 11m Displacement: 76.000tons (standard), 82.300tons (full load) Armour: 240mm Deck, 460mm Belt inclined at 20 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 4x2 51cm/45 Type 98 Cannons, 2x3 15,5cm/60 Type 90 Guns, 16x2 10cm/65 Type 98 DP-AA guns, 14x2 40mm/60 Type 5 AA Guns, 22x3 25mm/60 Type 96 AA Guns, 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating) Type 32 surface search radars (two set one on each side of the bridge structure rotating ones) Design A-150, possible variant C: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-C-758321728 On the same hull as on the B variant, I've used twin 20cm gun turrets as secondary guns. I've chosen this guns because some drawings and some sources says that the A-150 would be armed with these kind of weapons, though I found this unlikely. Originally the C version would be the same as B except the triple 15,5cm guns replaced by twin 20cm ones but I discarded the idea as it did not really change the effectiveness of the ship, actually decreases it in same way as the 20cm guns while more powerful and could shoot further their number of barrels and their reload time is'n better than the excellent 15,5cm ones deceasing their purpose as anti destroyer guns. On the other hand on this version I sacrificed some 10cm mounts to place two 20cm gun turrets at the beams similar to these old drawings by the late CanisD: In the end this design's has the following characteristics: Dimensions: 268 (wl) 275 (oa) x 40,5 x 11m Displacement: 77.700tons (standard), 84.000tons (full load) Armour: 240mm Deck, 460mm Belt inclined at 20 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 4x2 51cm/45 Type 98 Cannons, 6x2 20cm/50 Type 90 Guns, 10x2 10cm/65 Type 98 DP-AA guns, 14x2 40mm/60 Type 5 AA Guns, 12x3 25mm/60 Type 96 AA Guns, 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating) Type 32 surface search radars (two set one on each side of the bridge structure rotating ones) Design A-150, possible variant D: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-D-758484616 This variant of mine features triple rather than twin 51cm turrets for the main artillery of the proposed A-150 type battleships. As accurate data are not available currently I'm trying to make various designs based on the information found during the years! This version is basically a widened Yamato hull with 41m beam and similar to my A variant, thoughit lacks secondary guns but extra space was allocated for the engines. My design has the following characteristics: Dimensions: 244 (pp) 256 (wl) 263 (oa) x 41 x 11m Displacement: 72.600tons (standard), 78.600tons (full load) Armour: 250mm Deck, 460mm Belt inclined at 20 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 3x3 51cm/45 Type 98 Cannons, 16x2 10cm/65 Type 98 DP-AA guns 14x2 40mm/60 Type 5 AA Guns 22x3 25mm/60 Type 96 AA Guns 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating) Type 32 surface search radars (two set one on each side of the bridge structure rotating ones) Design A-150, possible variant E: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-E-758761470 I've continue my possible A-150 "Super Yamato" design series with the second triple turreted design on the same idea I've done the B version. Like the A-150 B variant the hull was widened to 41 meters and lengthened to 263m on the waterline otherwise the same as the D version. My design has the following characteristics: Dimensions: 262 (wl) 269 (oa) x 41 x 11m Displacement: 75.000tons (standard), 81.200tons (full load) Armour: 250mm Deck, 460mm Belt inclined at 20 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 3x3 51cm/45 Type 98 Cannons, 2x3 15,5cm/60 Type 90 Guns, 16x2 10cm/65 Type 98 DP-AA Guns 14x2 40mm/60 Type 5 AA Guns 22x3 25mm/60 Type 96 AA Guns 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating) Type 32 surface search radars (two set one on each side of the bridge structure rotating ones) Design A-150, possible variant F: https://www.deviantart.com/tzoli/art/A-150-Super-Yamato-class-possible-variant-F-758801787 This is my last A-150 design very similar to my earlier C version where I've added more secondary 20cm guns sacrificing some 10cm AA guns. Only one Japanese Yamato type battleship remains, the mysterious last battleship design of Japan the 100.000ton battleship supposedly proposed in around 1942 and to be armed with 51cm cannons. My design has the following characteristics: Dimensions: 262 (wl) 269 (oa) x 41 x 11m Displacement: 76.600tons (standard), 83.000tons (full load) Armour: 250mm Deck, 460mm Belt inclined at 20 degrees Engines: 200.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.000nm at 16knots) Armaments: 3x3 51cm/45 Type 98 Cannons, 6x2 20cm/50 Type 90 Guns, 10x2 10cm/65 Type 98 DP-AA guns, 14x2 40mm/60 Type 5 AA Guns, 12x3 25mm/60 Type 96 AA Guns, 10x21 120mm Type 5 AA Rockets 7x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 13 air search radar antennaes (two set, both sides on the mainmast) Type 14 air search radar (one set, on top of the aft range finder) Type 21 air search radars (two set, on each arms of the main range finder fixed non rotating)

Last Japanese Battleship proposal: https://www.deviantart.com/tzoli/art/Last-Japanese-Battleship-proposal-759738735 Ages ago (more like a decade or more...) I've found a mention on some naval sites and forums that even after the A-150 "Super" Yamato the Japanese considered building or designing battleships surpassing even the size of the A-150 type! This design was known as the 100.000ton "Mega" Yamato. To my knowledge only two data was available about this mysterious proposal: A Displacement of 100.000tons and an armament of 51cm cannons! Based on this two data, knowledge on the Yamato preliminaries, the Yamatos themselves and the possible A-150 variants, this is my interpretation of this massive battleship armed with the most modern weapons and equipment of the Imperial Japanese Navy! Like on the previous A-150 series I've put a second 15,5m range finder aft in place of Yamato's 10m secondary rangefinder and enlarged the main rangefinder atop the bridge to 17meters! I've also further enlarged the main superstructure bridge and conning tower compared to the A-150's. Sidenote: It isn't impossible that the 100.000ton design was another A-150 variant with large size heavy armour and many guns! With this drawing I officially done drawing all the Proto-Yamato, Pre-Yamato, Yamato Preliminaries, Yamato variants and Post-Yamato designs I've started in March! My design the following characteristics: Dimensions: 280 (wl) 287 (oa) x 41 x 12m Displacement: 95.000tons (standard), 105.000tons (full load) Armour: 250mm Deck, 460mm Belt inclined at 20 degrees Engines: 230.000shp, 4 shafts, Steam Turbines Speed: 54km/h (29knots) Range: 13.300km at 30km/h (7.200nm at 16knots) Armaments: 4x3 51cm/45 Type 98 Cannons, 2x3 20m/50 Type 90 No.2 Guns, 16x2 12,7cm/50 Type 1 / Type 5 DP-AA guns, 44x2 40mm/60 Type 5 AA Guns, 12x21 12cm Type 5 AA Rockets 6x Seaplanes (Aichi E16A Paul and Mitsubishi F1M Pete planes) Sensors: Type 14 Air search radar (one set on top of the aft secondary rangefinder) Type 21 Air search radars (six sets, one on each High angle range finder tower) Type 22 Surface search radars (two sets, one on each side of the mainmast) Type 23 Gunnery Control / air search radars (Modified sets of 20, one on each machine gun director) Type 24 Air search / gunnery control radars (two sets, one on each arms of the main 17m rangefinder) Type 32 Surface search radars (two sets, one on each side of the bridge superstructure in place of the 13mm AA MGs on the Yamatos) Type 42 Searchlight control / gun laying radars (four sets, one on each side and above the 2nd and 6th pair of 12,7cm heavy AA gun turrets) More info on the used radars can be found here: http://www.combinedfleet.com/radar.htm http://pwencycl.kgbudge.com/R/a/Radar.htm http://home.e01.itscom.net/ikasas/index.htm http://home.e01.itscom.net/ikasas/catalog/catalog.htm http://www.yokohamaradiomuseum.com/radar.html http://www17.big.or.jp/~father/aab/kikirui/navy_radar.html#list And some info on the weapons used: http://navweaps.com/Weapons/WNJAP_20-45.php http://navweaps.com/Weapons/WNJAP_8-50_3ns.php http://navweaps.com/Weapons/WNJAP_5-50_t1.php http://navweaps.com/Weapons/WNUS_4cm-56_mk12.php http://navweaps.com/Weapons/WNJAP_12cm_AA_Rocket.php
