    Suggestion Swedish ships - example minor nation

    I dunno, I don't think it matters that much since a Swedish cruiser line is exceedingly unlikely and even a pan-European cruiser line is really kind of a stretch as far as I know.

    Suggestion Swedish ships - example minor nation

    Småland is, as far as I know, the only 20th century Swedish artillery warship preserved anywhere in the world. Everything else - all the destroyers, all the armored ships and the Tre Kronor class - was either scrapped or sunk as target practice. So there is that. Still, I think Tre Kronor would probably be easier to pitch as a pre-release premium than Småland.

    Suggestion Swedish ships - example minor nation

    I never really found any context for those blueprints, unfortunately. My best guess is that it was part of some kind of pretty far-flung tactical study and/or attempt to figure out a modern but bathtub-sized aircraft carrier just to see what such a thing would be like. I don't think it was actually seriously considered for construction, or more noise would have been made about it. Still funny to see an aircraft carrier with an icebreaker bow though. The Baltic Sea produces the best special snowflake ships.

    For the record, there has been some previous research here. I also have a bunch of historical source material here, both from books and from archive sources. I really don't think you need Argentina-Lappland as a T10 by the way, in fact Halland in her historical form might already have guns that are too good. She already fires (historically) 30% more shells per minute than the Gearing does (in game, base reload), but the 12 cm akan M/50 is also a better gun than the 5"/38 on the US DD's in other ways (not surprising considering how much newer it is). The caliber may be smaller, but the round is only slightly lighter (23.5 kg to the 5"/38's 25 kg) and the ballistics are significantly better. The 5"/38 had a historical max range of about 16km and a flight time to 10000 yards (9.1 km) of 22 seconds, while 12 cm akan M/50 had a max range of about 20.5 km and a flight time to 9.1 km of only 17 seconds. It's roughly halfway between the Russian 130mm (non-Khaba version) and the 5"/38, or maybe pretty close to the German 127mm on the Z-52, although I don't have good numbers on that one. I think an all-Swedish destroyer line is not very difficult to put together with just one or two paper ships, but there's really not much opportunity for any other line at all.

    I found the blueprint books! Lots of engineering porn but also quite a bit of useful stuff like very detailed armor layout etc. I think I'm gonna let Tre Kronor go for now though. I'll see if I find something about the destroyers, to get us back on topic... :V

    Not a shell design expert either, but I think stgr is a bit of an odd duck. As far as I know it's basically a HE round with a bit better armor penetration. It is nose fuzed (sar = spetsanslagsrör, available as either ö(gonblickligt) or f(ördröjt)) but unlike on the HE round there is no proximity fuze or timed fuze. I think it was intended as anti-ship HE while the regular HE was more for AA and completely unprotected targets. The hpgr is the "real" SAP equivalent I think. As for the AP shell, I really don't know what's up with that. I did notice though that all the rounds weigh almost exactly the same, so I wonder if that's got something to do with it - maybe the weight was limited by something. I don't know what's up with the stated penetration values either, they seem bizarrely low.

    The AP shell is much shorter and stubbier (newer ballistic table, from 1957, with drawings of all the shells near the end). Ballistic table for the 12 cm akan M/50 (Halland) Almost everything you ever wanted to know about Tre Kronor. I didn't photograph all of it but what's there should be more than enough to keep you entertained for a while. There's supposed to be an appendix to this with graphs and armor schemes and stuff that seems highly interesting, but it wasn't in the archive box. Dunno where it's at, but I'll keep looking. Note that some of the drawings are very early designs and probably don't match the final product. Some random stuff gleaned from this: rudder shift at 32 knots from max starboard to max port (35° to each side): half a minute. Turret traverse: up to 8° per second.

    No, typo. It's 60°. Other questions: not much to add at the moment but I'm planning to go back on Saturday and check out some stuff from the actual archives, not just books. I'll take a look at the ballistic tables for the various 12 cm guns too though.

    Hello again! I passed by the national archives library the other day and found some stuff in (among other things) the aforementioned book that may be of interest. See here for a bunch of Swedish naval guns (mainly ones used on destroyers). All rates of fire are practical sustained, not peak. Furthermore: Ballistic tables for 15,2 cm kanon M/42 (as used on the Tre Kronor class). Muzzle velocity with AP about 880 m/s (better than the Belfast but not on Budyonny's level), theoretical max range 24 km. Armor layout for a few cruisers, Tre Kronor bottom right. (Kvl = konstruktionsvattenlinje = design waterline). Anecdotes etc: - Four of the six Göteborg class destroyers reached 41 knots in speed trials - Both Tre Kronor and Göta Lejon exceeded the contract speed of 33 knots in trials, but I don't know by how much. - On a longer trip (not just a speed run), Tre Kronor averaged 32 knots in open sea between Stockholm and Karlskrona (about 450 km or somewhere in the neighborhood of 10 hours). - Göta Lejon outran the Soviet cruiser Sverdlov in the North Sea on the way home from the crowning of Elizabeth II in Britain, in 1953. - The Tre Kronor class had a central AA director for the 15,2cm guns from launch and they could elevate up to +70°. Let me know if you want help interpreting anything.

    Lots of interesting questions, but unfortunately I can't really answer most of them... I spent only a few hours poking at ship archives and I really don't know much about them. There is a very big and comprehensive book about Swedish destroyers though that I've been thinking I should pick up from the library, but I haven't gotten around to it. The reason I had the torpedo data was because I happened to have come across a pretty comprehensive document with historical details about Swedish torpedoes up to the early 1950's. I don't know anything about the 3x3 Tre Kronor proposal - everything I know indicates that the reason the ships ended up looking like they did was that Bofors had the turrets half-made already (for some foreign customer, don't remember which country - the Netherlands probably?) when the war broke out. I've seen text proposals for three twin turrets but not 3x3. All the archive stuff I've found about Swedish ships is in this open Google Drive folder - everything in Swedish of course but there's quite a lot of drawings. Since I've been more into ships than tanks recently and the Swedish tank tree is basically ready for release now, maybe I should take an archive dive into the ships world again...

    Historical stats for the Swedish Torped 14 are as follows. Caliber: 533mm Length: 7.58m Weight (combat ready): ~1700kg Warhead: 248 kg TNT Max speed: ~43 knots Min speed: ~32 knots Range: 10,000m @ max speed, ~15,000m @ min speed Now, this probably doesn't sound too good as far as range and speed goes, but many torpedoes in game have their speed buffed significantly over historical values. The mk 15 mod 3 on the Benson for example historically did 4,500 yards (4,100 m) @ 45 knots or 9,000 yards (8,200 m) @ 33.5 knots - in game, 9,200m @ 55 knots. The mk 17 on the Gearing had a historical top speed of 46 knots; in game 66 knots. So sticking with the theme of retaining roughly historical torpedo ranges but buffing speed 30% or so, 10-ish km @ 65-ish knots doesn't sound too unreasonable. The main problem is the relatively small warhead - it's comparable to the Benson's stock mk 15 mod 0 (224kg), while the mk 17 warhead weighed in at 399kg. If we "do a Fletcher" and also consider submarine torpedoes there's also Torped 25 which was ~5-7 knots faster but had ~5000m shorter range and a ~50kg heavier warhead. 53 cm torped 11 did 10,000m @ 30 knots or 5,000m @ 40 knots. Warhead 255kg "novit", which is some proprietary Swedish explosive that is almost completely ungooglable. Don't know what it consists of. 45 cm torped m/15 did 7,000m @ 26 knots or 3,000m @ 36 knots, or in modernized form (m/15A) 5,000m @ 31 knots. Warhead 151kg TNT. edit: by the way, the 5+3 torpedo tube arrangement on the Halland is a later invention, originally it was 4+4. They changed it to 5+3 to make space for missile launch ramps but that's not relevant for WoWS. AA on the Halland should be pretty okay - it only has 6 40mm Bofors to the Gearing's 12, but it also has a twin 57mm secondary DP turret that should be fairly nasty, in addition to its DP main guns.

    Swedish "aircraft carrier cruiser", 1946

    No, sorry. Despite having been all over a number of different archive locations that seemed like they could be relevant, I've been unable to locate anything related to this design. I've been in contact with the Navy Museum; they didn't know anything about it. I've asked the archivists at the National Archives, and they've pointed me to a few places where I've looked and found nothing. There are a few more places where I could look but I'm really busy with the Swedish tree for World of Tanks at the moment so I don't really have the time for ship research right now. Sorry.

    Sweden in World of Warships

    Utredning och Förslag angående Sjökrigsmaterielens sammansättning m.m., avgivet jämlikt Kungl. Maj:ts beslut den 24 september 1943 188 pages of discussion of the Future of Naval Warfare in Sweden. Very interesting (if you are a gigantic nerd). If you are only a medium sized nerd, go directly to IMG_7297.jpg and start reading about proposed ship types. We've seen some of them before but this gives them a bit more context. Enjoy!

    "Flotilla leader", 4660 tonnes, l.o.a. 170 m, 35 knots, 4x 15,2 cm automatic guns, 4x 57mm automatic guns, 12x 40mm AA autocannons. Smaller version of the above. 3000 tonnes, l.o.a. 141 m, 35 knots, 6x 12 cm automatic guns, 8x 40mm AA autocannons, 12x 53 cm torpedo tubes (six fixed on each side). Destroyer. Basically proto-Halland. 2400 tonnes, l.o.a. 133 meters, 35 knots, 4x 12 cm automatic guns, 8x 40mm AA autocannons, 12x 53 cm torpedo tubes (six fixed on each side). Unlike the other proposals, there are a lot of words that go with these that I don't feel like summarizing right now, but if you can read Swedish feel free to go hog wild in this Google Drive folder. It's a couple hundred pages, no biggie. There are some funny drawings of what the navy in 1946-1947 thought a guided missile cruiser might look like in the future in there too to keep you entertained (spoilers: it doesn't exactly have a Vertical Launch System).
