    Acoustic torpedo

    Hello everybody, in World of Warships has been always discusion about submarines and if it is possible for submarines to be in this game. With the Halloween event Terror of the Deep in 2018, there has been opinion that this fun mode is just a test. This was confirmed 2 days ago on Gamescom 2019. Wargaming is planning to create German and US Submarine tech tree branch for WoWs. They showed us early-stage gameplay of submarines and DDs against each other. In these gameplays, after torpedo from submarine is fired, you can try to mark the ships bow or stern, so the torpedo can become homing torpedo. I have been reading forum for 2 days and many people are concerned about homing torpedoes in this gameplay (and rightfully so). So let's take a closer look at these homing torpedoes to understand them more. Torpedoes are the main source of damage for submarines, therefore if are homing torpedoes available for them or not is a huge thing for their success. Please keep in mind that this article is ONLY about homing torpedoes, their history and possible implementation in game. In this article, just after historical part, there will be few ideas of implementation of homing torpedoes in game. This article IS NOT about: -submarines in game would be good/ bad -Anti-submarine warfare -balance of submarines and their implementation in game Keep this in mind. Also I apologize for any grammar mistakes, english is not my native tongue. Acoustic torpedoes Acoustic torpedoe is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar (acoustic homing). Acoustic homing torpedoes are equipped with a pattern of acoustic transducers on the nose of the weapon. By a process of phase delaying the signals from these transducers a series of "acoustic beams" (i.e. a variation of acoustic signal sensitivity dependent on the incident angle of the noise energy). In early homing torpedoes the "beam patterns" were fixed whereas in more modern weapons the patterns were modifiable under on-board computer control. These sensor systems are capable of either detecting sound originating from the target itself i.e. engine and machinery noise, propellor cavitation, etc., known as passive sonar , or responding to noise energy reflections as a result of "illuminating" the target with sonar pulses, known as active sonar. Acoustic torpedoes in World War II. The first passive acoustic torpedoes were developed nearly simultaneously by the United States Navy and the Germans during World War II. The Germans developed the G7e/T4 Falke, which was first deployed by the submarines U-603 , U-758 and U-221 in March 1943. Few acoustic torpedoes were actually used and quickly phased out of service in favor of the T4's successor, the G7es T5 Zaunkönig torpedo in August 1943. The T5 first saw widespread use in September 1943 against North Atlantic escort vessels and merchant ships in convoys. The German U-boats now had an effective "fire and forget" weapon capable of homing-in on attacking escorts and merchant ships and doing so in close quarters of only three or four hundred yards. By summer of 1943, the German U-boat campaign was experiencing severe setbacks in the face of massive anti-submarine efforts integrating Coastal Command attacks in the Bay of Biscay, the deployment of merchant aircraft carriers in convoys, new anti-submarine technologies such as hedgehog and improved radar, and the use of dedicated hunter-killer escort groups. On the Allied side, the US Navy developed the Mark 24 mine, and was actually an aircraft launched, anti-submarine passive acoustic homing torpedo. The first production Mk. 24s were delivered to the U.S. Navy in March 1943, and it scored its first verified combat kills in May 1943. About 204 torpedoes were launched against submarine targets, with 37 Axis submarines being sunk and a further 18 damaged. Countermeasures The German T5 torpedoes were countered by Allied introduction of the Foxer noise maker. Foxer was the code name for a British built acoustic decoy used to confuse German acoustic homing torpedoes. A US version codenamed FXR was deployed at the end of September 1943 on all transatlantic escort vessels but was soon replaced by the more effective Fanfare noisemaker. The device consisted of one or two noise-making devices towed several hundred metres astern of the ship. The noise makers mechanically generated a far more louder cavitation noises than the ships propellers. This noise distracted the acoustic torpedoes away from the rear of the ship into a circling pattern around the noise maker until the torpedo ran out of fuel. The downside of the Foxer was that it also rendered the own ship's ASDIC ineffective and concealed any other U-boat nearby that could home in on the convoy. Nevertheless, the FXR countermeasure proved to be highly effective in decoying German acoustic torpedoes. Of the c. 700 fired G7es torpedoes about only 77 had found their aim. Please keep in mind, that characteristics of acoustic torpedoes (speed,...) are historically accurate and will be (most likely) in game changed. Mark 24 mine The Mark 24 mine (also known as FIDO or Fido) is an air-dropped anti-submarine warfare weapon (ASW) incorporating passive acoustic homing system and torpedo integration. It was used by the United States, the British and Canadian forces during the Second World War and entered service in March 1943 and remained in use with the US Navy until 1948. The deceptive name of "Mark 24 Mine" was deliberately chosen for security purposes, to conceal the true nature of the weapon. Characteristics: Designed: 1942 Number of acoustic torpedoes built: 4000 Length: 84 inches (213,36 cm) Diameter: 19 inches (48,26 cm) Mass: 680 pounds (308,44 kg) Effective firing range: 4000 yards (3,657 km) Search duration: 10 minutes Speed: 12 knots Warhead weight: 92 pounds (41,73 kg) Detonation mechanism: Mk 142 Fuse- contact exploder Description: Upon water entry, FIDO performed a circular search at a predetermined depth controlled by a bellows and pendulum system (acoustic torpedo could change it's direction not only horizontally but also vertically). This continued until the potential target's 24 kHz acoustic signal detected by the hydrophones exceeded a predetermined threshold level, at which point control was then shifted to the passive acoustic proportional homing system. Initially the torpedoes were set to search for a target at a depth of 50 feet (15 m), this was later changed to 150 feet (45 m). To prevent the torpedo accidentally attacking surface ships, it resumed its circling search if it rose above a depth of 40 feet (12 m). The torpedo's relatively low speed was kept secret because, although U-boats could not outrun the torpedo when submerged, they could outrun it on the surface. Mark 27 torpedo The Mark 27 torpedo was the first of the United States Navy 19-inch (48-cm) submarine-launched torpedoes. The torpedo employed a passive acoustic guidance system and was intended for both submarine and surface targets. Nicknamed "Cutie" by submarine crews, the Mark 27 entered service in 1943 as a defensive weapon. The torpedo was classified as obsolete in the 1960s. The Mark 27 was essentially a Mark 24 mine which had been modified for submarine launching in a 21-inch submerged torpedo tube by the addition of 1" wood guide studs mounted on the torpedo's outer shell. The Mark 27 Mod 4 torpedo was designed by the Ordnance Research Laboratory of Pennsylvania State University in 1946 as an improved version of the Mark 27 torpedo.Fully compatible with electrical setting fire control systems through the use of the standard 65-pin umbilical cable, this weapon was in service on submarines for about ten years. It was withdrawn from service use in 1960 with the introduction of the Mark 37 torpedo. Mark 27 torpedo characteristics: Designed: 1943 Number of acoustic torpedoes built: 1000 Length: 90 inches (228,5 cm) Diameter: 19 inches (48,26 cm) Mass: 720 pounds (326,586 kg) Effective firing range: 5000 yards (4,572 km) Search duration: 12 minutes Speed: 12 knots The Mark 27 Mod 4 torpedo characteristics: Designed: 1946 Number of acoustic torpedoes built: 3000 Length: 125.75 inches (319,405 cm) Diameter: 19 inches (48,26 cm) Mass: 1175 pounds (532.97 kg) Effective firing range: 6200 yards (5,6693 km) Search duration: 12 minutes Speed: 15,9 knots Warhead weight: 128 pounds (50,05 kg) Detonation mechanism: Mk 11 Mod 2 - contact exploder G7e/T4 Falke Early in 1933 Germany started development and testing of acoustic homing mechanisms for torpedoes. With the introduction of Falke, U-boats could remain more deeply submerged and fire at convoys with nothing to give away their position but the noise of their screws. Falke worked much like a normal straight-running torpedo for the first 400 m of its run, after which its acoustic sensors became active and searched for a target. The sensitive sound-sensing equipment in Falke required the torpedo be as quiet as possible, hence it ran at only 20 knots (37 km/h); in addition, the firing U-boat was forced to stop its motors. Falke was intended to home on merchant targets. Only known to have been fired in action by three U-boats, U-221, U-603 and U-758. Although regarded as successful, Falke was rapidly phased out of service. It was replaced by the G7es/T5 "Zaunkönig" , which was faster and better able to home onto the sound of fast moving warships as well as merchant traffic. G7e/T4 Falke torpedo characteristics: Designed: about 1940 Length: 7.186 m Diameter: 533 millimetres (21.0 in) Effective firing range: 7500 m Search duration: 12,16 minutes Speed: 20 knots Warhead weight: 440 lbs. (200 kg) Hexanite G7es (T5) Zaunkönig When compared to G7e/T4 Falke, the Zaunkönig was faster, had more range, possessed a magnetic or contact detonator and could be equipped with a percussion pistol. The homing system consisted of two hydrophone receivers and altered the direction of the rudder via an electropneumatic device. The acoustic homing torpedo was specifically designed as to be attracted by the pitch of an escort's proppellors and would — even if aimed inaccurately — explode under the ship's stern. The acoustic homing torpedo required a minimum distance of 400 metres (1,300 ft) to lock onto the target after launch. After at least two unconfirmed instances of U-boats (U-972 and U-377) sinking after being allegedly hit by their own torpedoes, the BdU ordered the submarines to dive to 60 metres (200 ft) and go completely silent after launching acoustic torpedoes to minimize the risk. The first 80 T5s were delivered on 1 August 1943, and the weapon was first used in a large-scale maneuver against the North Atlantic convoys ONS 18/ON 202 in late September 1943. Despite some initial success, in particular sinking destroyers and corvettes, the Zaunkönigs effectiveness was quickly nullified by the introduction of a decoy known as Foxer noise maker. In spite of highly effective Allied countermeasures, a total of over 700 T5s were fired in combat, sinking 77 ships. G7es (T5) Zaunkönig torpedo characteristics: Designed: 1933 Length: 7.186 m Diameter: 533 millimetres (21.0 in) Effective firing range: 5,750 meters Search duration: 7,6 minutes Speed: 24.5 knots Warhead weight: 274kg G7es (T11) Zaunkönig II Realizing what was happening, the Germans introduced the second generation of acoustic torpedoes which were more accurately tuned to a ship’s propeller noise. The G7es Zaunkonig II also had an improved range and sensitivity. The Zaunkonig II could also be launched from up to depths of 50 meters (164 feet), compared to 15 meters (49 feet) for Zaunkonig I. G7es (T11) Zaunkönig II has basically the same characteristics as G7es (T5) Zaunkönig. Acoustic torpedoes in WoWs Historically, acoustic torpedoes were only meant as a weapon against surface ships (with the exception of the Mark 24 mine) and I would like to keep it that way. Homing torpedoes should always have lower speed, when compared to torpedoes of DDs. 1) Highly reduce torpedo turning capabilities This way torpedoes would be only slightly enhanced in comparison to normal torpedoes. The torpedoes would be able to adjust their course but with such minimum affect, that it will be only slightly harder for the targeted ship to avade the homing torpedo. 2) Torpedoes homing capabilities would be active after certain distance G7e/T4 Falke torpedo and G7es (T11) Zaunkönig II had their acoustic searching activated after 400 meters. In naval combat 400 meters is a short distance. So why don't take this distance, where torpedo is not adjusting its direction, and make it longer. It could be activated after torpedo travelled for example 10-50% of its maximum range (only testing will say if it is too much/ little or alright...). This way captains will have to make a choice: a) fire at longer distances- torpedo will be adjusting its direction towards target longer but it will take much longer to get to target and thus having much higher chances that the target will change course (he is evading enemy shells, torpedoes, wants to cap, etc. ...) and torpedo will miss the target, because of its limited turning capabilities b) fire at medium distances- torpedo will be adjusting its direction towards target only for a while, shorter time of travelling c) fire at short distances- homing torpedo will act just like any other in game- it will go in a straight line 3) Torpedoes homing radius Torpedoes will become homing only after they are in certain distance from target. What I mean by this is a folowing example: Submarine fires torpedo. Torpedo goes in a straight line. When the torpedo detects enemy ship in 1 km radius (for example), then it will starts to hunt down the enemy ship. This way, you can't alter the target for torpedo, creating sometimes situations, where you aimed for BB, but your torpedo starts chasing enemy DD, which is closer to the trajectory of the torpedo and having worse chances to hit. Once the torpedo starts chasing, the target cannot be changed. 4) Firing at lower speeds Just like with G7es (T5) Zaunkönig, your submarine doest want to be targeted by it own homing torpedoes. This gives captains 2 choices: a) fire torpedo at a straight line, but maintaining higher speed b) significantly slow down and fire homing torpedoes (being slower=less noise) Slowing down, while being chased down by a DD can decide your fate. 5) Give other ships and planes noise makers This could be consumable with 3-4 charges given to ships to defend themselves from homing torpedoes. Planes would have this to assist their team at front lines of the battle. 6) Targeting friendly ship Acoustic torpedoes lacked ability to tell friend from foe. If you mark friendly ship by mistake, torpedo will target the friendly vessel. This is a terrible idea and I hope we won't see it . Summary: Historical part Acoustic torpedoes were slow (although German torpedoes are faster), couldn't change depth (exept for Mark 24 mine) and lacked ability to tell friend from foe. They were meant as a weapon against surface ships (exept for Mark 24 mine). Possible implementation in game: By highly reducing torpedo turning capabilities, delaying their homing abilities, reducing submarines speed while firing or giving all other ships defensive consumables. They also should be against surface ships (not submarines). Their speed would be higher than in real life (I assume) but lower then other torpedoes. Submarines have still a long way, before they get to the random battles and maybe we even won't see any homing torpedoes at all. Who knows, all is a subject that could be changed. One way or another, Wargaming should be careful about this... I will be glad if you leave your comment below. I hope you enjoyed this article and have a nice day.

    HMS Dido

    Hello everybody, I have put together history and possible implementation of light cruiser HMS Dido in World of Warships. Please keep in mind that this is just fan made, not official news of upcoming new ship. Also I apologize for any grammar mistakes, english is not my native language. HMS Dido History Creation Even before World War II, Royal Navy was aware of a threat posed by aircraft. The temporary solution was to rebuild old cruisers to floating air defence platforms. The other solution to this problem was to design a new light cruisers with appropriate air defence armament. This program produced 16 Dido-class cruisers. Dido-class cruisers had maximum speed just over 32 knots and could sail up to 4,880 miles with speed at 16 knots. She was armed with 5x2 5.25 inch dual purpuse guns, 3 turrets on the bow and 2 turrets on the stern. These turrets were originally designed for the King George-class battleships. However, thanks to heavy weight of the turrets, these dual purpuse guns weren't excellent for anti-aircraft fight and they weren't very effective against ground targets. She also carried 2x3 533mm torpedo tubes. Last five ships of the Dido-class didn't have 3 turrets on the bow, but only 2 turrets. They had reinforced mast and lower-profile smoke funnels. HMS Charybdis and Scylla were armed with 4,5 inch dual porpuse guns. They were cheaper and had better anti-aircraft capability. Ships of the class: -total number of ship produced: 16 -HMS Dido (1939) -HMS Euryalus (1939) -HMS Naiad (1939) -HMS Phoebe (1939) -HMS Sirius (1940) -HMS Bonaventure (1939) -HMS Hermione (1939) -HMS Charybdis (1940) -HMS Cleopatra (1940) -HMS Scylla (1940) -HMS Argonaut (1941) -HMS Bellona (1942) -HMS Black Prince (1942) -HMS Diadem (1942) -HMS Royalist (1942) -HMS Spartan (1942) Carrier HMS Dido (37) became the lead ship of this new class. Her keel was laid down on October 26th, 1937 by Cammell Laird of Birkenhead. She was launched on July 18th, 1939 and commissioned on September 30th, 1940. Dido's first mission, in November 1940, was to escort the aircraft carrier Furious to West Africa. Dido then spent four months on convoy duty in the Atlantic before running suppliesto Malta where she joined the Eastern Mediterranean Fleet in April 1941. In May 1941, she was sent to Crete and assisted in evacuation of the British forces. On 29 May 1941 Dido was badly damaged by bombs whilst taking troops from Crete to Alexandria. Then Dido was sent to the Brooklyn Navy Yard. There she was refitted and rejoined the Eastern Mediterranean Fleet in December 1941. The first three months of 1942 were spent on convoy escort duty between Alexandria and Malta. In March that year, Dido took part in a bombardment of Rhodes. A week later she participated in the Second battle of Sirte. On 18 August 1942 she returned to Massawa for repairs of the bomb-damaged stern. Dido then spent the rest of the year supporting the British campaign in North Africa before being transferred to the Western Mediterranean Fleet in December 1942. After that, Dido performed the duty of anti-aircraft guard at Bone and Algiers until March 1943. In April 1943, Dido returned to Liverpool for a 3-month refit before rejoining the Western Mediterranean squadron. In May 1943, Dido took part in diversionary bombardments against North Sicily during the landings. Dido was then used as an anti-aircraft guard for invasion bases at Palermo and Bizerte. On 12 September 1943, Dido escorted 600 troops to Taranto where the Italian Fleet surrendered. From Taranto, Dido went to Sorrento where she supported troops. October and November 1943, Dido returned to Alexandria for another refit. On return to service, Dido spent time in Malta and Taranto. After that, she participated in a diversionary action off Civitavecchia in support of the landing at Anzio. In August 1944, Dido supported the Allied landings in France and in September 1944 Dido returned to the UK. In October 1944, Dido escorted a convoy to Russia before supporting carrier strikes off Norway. In April 1945, Dido escorted Apollo, Orwell, and Obedient to the North Kola Inlet to lay mines. Dido's last mission in the war was to go to Copenhagen, firing the last naval shot in the war in Europe on the way, for the surrender of the German Kriegsmarine which was signed aboard Dido. After the signing, Dido escorted the German cruisers Prinz Eugen and Nürnberg to Wilhelmshaven. In July 1945, Dido took King George VI and Queen Elizabeth to the Isle of Man. In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II. She was decommissioned and sold for scrap to Thos W Ward and scrapped at Barrow-in-Furness in 1957. Dido's blueprint HMS Dido in World of Warships: Class: light cruiser Tier: VI She would be a premium ship, purchased by dublons or free XP. She is a unique light cruiser and doesn't fit much in the light cruiser British tech tree.

HMS Charybdis Summary: Dido is light AA cruiser, similar to Atlanta, at tier VI and she plays very similar to Atlanta. Dido would have the "catapult launcher" guns with fast reload and weak armor. However, there are few differences: -Dido has better torpedoes -Atlanta has more guns -Dido has better concealment -Dido is one tier lower Because it is very similar to Atlanta I made 2 hull options: -Hull A- more guns with slower reload and better range and damage per shot - worse concealment than Hull B - only one consumable (I dont count Damage control party) - slightly worse torpedoes - slightly better long range and medium range AA defence -Hull B- less guns with lower caliber and damage per shot and slightly worse range - slightly better concealment - one consumable more -better short range AA defence Reason why I made two hulls for Dido is simples. I didn't want Dido to be Atlanta at tier VI. Also it is good to have options. Hull A has more damage per minute while Hull B is for more dangerous gameplay. I will be glad if you leave your comment below. I hope you enjoyed this article and have a nice day.
