One useful feature of the Type 93 torpedo is that on all ships to which they are mounted on as of [[Update 1.89 "Imperial Navy"]], extra torpedoes are stored on the ship and allows the torpedo launchers to be reloaded in battle, usually enough for one full reload of the torpedo launchers. While limiting the number of torpedoes the ship can send at once, this feature is very useful and allows these ships to carry much more torpedoes than most other ships. This is particularly useful in [[Realistic Battles]] as a single ship can launch multiple salvos of torpedoes without having to visit a capture point to reload. In [[Arcade Battles]], this will allow you to have a faster rate of fire for your torpedoes, since the torpedoes will replenish faster than the standard Arcade reload, allowing you to launch waves of torpedoes very quickly.

The Type 93 is a very useful weapon in the Encounter game mode, as their long-range and fast speed will allow it to strike at the enemy convoy immediately from spawn. They can also be used against players by firing a large spread in an area where one would expect many ships to pass through, such as a narrow pass. They can catch an enemy ship off-guard at a distance where most conventional torpedoes will not be able to reach and effectively shut down sections of the map where they are launched.

Without the required number of capital warships, nor the industry to produce them, to match the United States in the Pacific, Japan would not be able to win a prolonged gunfight with as there would always be more US ships than Japanese. Instead, they opted for a strategy in which series of mass torpedo attacks would weaken the US fleet ahead of a major decisive battle. Thus, development for a stealthy, long-range torpedo began in 1928.

Description

Mounted on various Japanese destroyers and cruisers, the Type 93 Torpedo is one of the best ship-launched torpedoes in the game. Combining an unrivalled 20 km range, excellent 91 km/h top speed, and large 627.2 kg equivalent warhead, this powerful torpedo can allow even light ships to effectively damage or even sink the largest ships in the game.

Effective damage

The Type 93 Model 1, mod 2 torpedo carries a warhead with a TNT equivalence of 627.2 kg, making it one of the most deadly torpedoes in the game, behind only the Type 93 Model 3 and Mk.16. A single hit is usually enough to severely cripple large ships such as heavy and light cruisers, if not outright sink them.

Comparison with analogues

The other version of the Type 93, Type 93 Model 3, has a considerably larger warhead at 998.4 kg TNT equivalent at the cost of having a max range 5 km less, at 15 km. The only other torpedo to surpass the Type 93 Model 1, mod 2 in warhead size is the 21-inch Mk.16 which has 915.2 kg TNT equivalent. However, the Mk.16 can only travel at a max speed of 85 km/h for 6.4 km. There is one torpedo that can match the Type 93 Model 1, mod 2 in range, the Seal DM2A1, but with less than half of the TNT equivalence in the warhead and roughly 60% of its max speed.

Compared with other common torpedoes used on destroyers and cruisers (Mk.15, G7a, G7E (mod.T5a), 53-38, 53-39, Mark V, and Mark IX), while some can match or even surpass the Type 93 Model 1, mod 2 in speed, none come close to combining that with long range and a large explosive charge.

Usage in battles

One useful feature of the Type 93 torpedo is that on all ships which carry it, extra torpedoes are stored on the ship which allows the torpedo launchers to be reloaded in battle, usually enough for one full reload of the torpedo launchers. While limiting the number of torpedoes the ship can send at once, this feature can be very useful, allowing these ships to carry a much larger amount of torpedoes than other ships. This is particularly useful in Realistic Battles as a single ship can launch multiple salvos of torpedoes without having to visit a capture point to reload. In Arcade Battles, this will allow them to have a faster rate of fire for torpedoes, since the torpedoes will replenish faster than the standard Arcade reload, allowing multiple waves of torpedoes to be launched at a quick pace.

The Type 93 is a very useful weapon in the Encounter game mode, as their long-range and fast speed will allow them to strike at the enemy convoy immediately from spawn. They can also be used against players by firing a large spread in an area where many ships are likely to pass through, such as a narrow pass. They can catch an enemy ship off-guard at a distance where most other torpedoes will not be able to reach and can effectively shut down sections of the map where they are launched.

Pros and cons

Pros:

  • Extremely powerful warhead
  • One of the fastest torpedoes in the game
  • Tied for longest range torpedo, at 20 km
  • Ships that carry Type 93 often carry a large amount, upwards of 16

Cons:

  • Ships that carry Type 93 must reload in order to access entire load

History

Without the required number of capital warships, nor the industry to produce them, to match the United States in the Pacific, Japan would not be able to win a prolonged gunfight with as there would always be more US ships than Japanese. To combat this disadvantage, the Imperial Japanese Navy developed a strategy in which series of mass torpedo attacks would weaken the US fleet ahead of a major decisive battle. For this, a long-range, stealthy torpedo would be needed. Both the British Royal Navy and the IJN had experimented with oxygen-driven torpedoes in the past; however, after casualties from premature explosion, development halted. It was in the wake of the new battleship HMS Rodney, which carried oxygen torpedoes, that interest renewed in Japan. Taking inspiration from HMS Rodney's torpedoes, development began in 1928 for a long-range, wakeless oxygen torpedo.

The resulting torpedo was the Type 93 torpedo, referred to as Sanso Gyorai (酸素魚雷, "oxygen torpedo"). The Type 93 torpedo had a diameter of 610 mm (24 inches), was 9 meters (29 feet, 6 inches) long, weighed 2700 kg, and was rather large compared to its contemporaries. Many torpedoes of the time used combustion engines with compressed air oxidizers for propulsion. In contrast, the Type 93 torpedo utilized pure, compressed oxygen as the oxidizer. Air is composed of roughly 20% oxygen and 78% nitrogen, the latter of which was a waste product that manifested as long bubble trails. Using pure oxygen allowed the Type 93 torpedo to effectively quintuple its fuel while also eliminating the nitrogen byproduct. This greatly reduced the torpedo's bubble trail and left it virtually wakeless. The use of oxygen allowed the Type 93 torpedo to carry a large explosive charge without sacrificing fast speeds and long range.

However, it was not without its drawbacks; the torpedo was prone early detonation, so a secondary compressed air tank was used at launch, switching to the oxygen tank once the torpedo was a safe distance away from the launching ship. The Type 93 torpedo was also more susceptible to shrapnel and shock-induced detonation, which lead to the loss of a number of Japanese warships.

This, combined with the extreme secrecy of the torpedo, resulted in the loss of many Allied ships. After the war, the Type 93 torpedo was dubbed "Long Lance" in the west.
