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|Mk.16]]. A single hit is usually enough to severely cripple large ships such as heavy and light cruisers, if not outright sink them.

The Type 93 Model 1, Mod 2 torpedo carries 490 kg Type 97 warhead, which is equivalent to 627.2 kg TNT. This makes it one of the most powerful torpedoes in the game, behind only the [[Type 93 Model 3 (610 mm)|Type 93 Model 3]] and [[Mk.16|Mk.16]]. A single hit is usually enough to sink destroyers and can cripple or even sink cruisers, depending on where it hit.

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 [[Mk.16|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.

<!--''Give a comparative description of torpedoes that have firepower equal to this weapon.''-->
  
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.
+
The other version of the Type 93 torpedo in the game, [[Type 93 Model 3 (610 mm)|Type 93 Model 3]], has a considerably larger warhead, 998.4 kg TNT equivalence, though this comes at the cost of having a maximum range that is 5 km less, at 15 km. The maximum speeds of both torpedoes are the same. The Torpedo Mode modification is not available for the Type 93 Model 3.
 +
 
 +
Besides the Type 93 Model 3, one other torpedo has a larger warhead is the [[Mk.16 (533 mm)|Mk.16 torpedo]], which has a 915.2 kg TNT equivalent warhead. However, the Mk.16 can only travel at a maximum speed of 85 km/h for only 6.4 km. In terms of maximum range and speed, there are several notable torpedoes: the [[Seal DM2A1 (533 mm)|Seal DM2A1 torpedo]], the [[53-39 (533 mm)|53-39 torpedo]], and the [[Type 89 (533 mm)|Type 89 torpedo]]. The Seal DM2A1 torpedo matches the Type 93 Model 1, Mod 2 in range, but it can only travel at 61 km/h and only has a 250 kg TNT equivalent warhead. The 53-49 torpedo has a slightly higher maximum speed, 94 km/h, but it has a smaller warhead, 317 kg TNT equivalence, and can only travel for 4 km. Finally, the Type 89 torpedo actually surpasses the Type 93 Model 1, Mod 2 quite substantially in both maximum range and speed, 38 km and 102 km/h respectively; however, it has a smaller warhead, only 267 kg TNT equivalence.

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.

While this does limit the number of torpedoes the ship can send at once, the total amount of torpedoes is often much more than what destroyers and cruisers of other nations can carry. This is 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 the torpedoes launchers to effectively have a faster rate of fire, since the torpedo launchers will refill faster than the standard AB torpedo reload.

 +
Be aware though that having extra torpedoes means that the ship essentially has above-deck, unarmoured ammo racks which can destroy the entire ship if detonated. These racks are, of course, emptied as their torpedoes are used to refill the launchers, so it might be a good idea to launch off at least enough torpedoes to empty the racks right away after spawning in. Unlike other torpedoes and fortunately for the Type 93 Model 1, Mod 2, its unique combination of both a large maximum range and a fast top speed make such strategies viable. By firing a wide salvo at the beginning of the match towards areas where many enemy ships are likely to be pass through (for example, capture points or narrow passes), these sections of the map can effectively be blocked off, and, because of their range and speed, they can catch enemies off-guard who either don't expect seeing torpedoes so early in the match or don't expect seeing torpedoes in areas of the map where other torpedoes usually fail to reach. The Type 93 Model 1, Mod 2 is a particularly useful weapon in the Encounter game mode. The 20 km maximum range is more than enough to reach across the entire map, which usually spans roughly 15 km. Ships armed with the Type 93 Model 1, Mod 2 torpedoes can strike the enemy team's AI convoy immediately from spawn.  
  
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.
+
For the reason that the maps are simply too small, there is no reason to use Torpedo Mode modification in random battles as the increased range doesn't provide any real benefits at the cost of speed being lowered to average levels. However, the Torpedo Mode modification should be used in naval [[Enduring Confrontation]] with its much larger maps and longer match times. In this mode, the strategical value of having a longer range is more than the tactical value of having more speed.

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 a 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.

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 war with the US or engage them in a massive battle as there would always be more US ships than Japanese ships. To combat this disadvantage, the Imperial Japanese Navy developed a strategy in which a 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 torpedoes in the past. The use of oxygen as an oxidizer, while very efficient, is also extremely dangerous, and, after casualties from premature explosion, development halted. It was in the wake of the new British battleship HMS Rodney, which carried oxygen torpedoes, that interest renewed in Japan. Taking inspiration from HMS Rodney's torpedoes, development began again 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, 490 kg of Type 97 explosive, without sacrificing fast speeds and long-range.

The resulting torpedo, the Type 93 Model 1, Mod 1 torpedo, referred to as Sanso Gyorai (酸素魚雷, "oxygen torpedo"), entered service in 1935. The Type 93 torpedo had a diameter of 610 mm (24 inches), was 9 meters (29 feet, 6 inches) long, weighed 2700 kg, and, being a 24-inch torpedo, was rather large compared to its contemporaries, most of which were 21-inch torpedoes. Many torpedoes of the time used combustion engines for propulsion with compressed air as the oxidizer. In contrast, the Type 93 torpedo utilized pure, compressed oxygen as its oxidizer.

The use of oxygen allowed the Type 93 torpedo to carry a large explosive charge, 490 kg of Type 97 explosive, without sacrificing fast speeds or long range.  
  
However, it was not without its drawbacks; the torpedo was prone to 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.

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. Most notable is the case of the light cruiser Suzuya, which had its Type 93 torpedoes detonate from a near-miss air attack, sinking the entire ship.
  
The Type 93 torpedo entered service in 1935. Japanese light forces would use the Type 93 in night attacks against Allied shipping, where the stealthy torpedo could find its target before the enemy was even aware that there were torpedoes in the water. 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.

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

Description

The Type 93 Model 1, Mod 2 is one of two versions of the 24-inch (610 mm) Type 93 torpedoes, the other being the Type 93 Model 3. Mounted on many destroyers and cruisers in the Japanese naval tech tree, the Type 93 torpedo has one of the furthest range and is one of the largest and fastest ship-launched torpedoes in the game. This powerful torpedo can allow even light ships to remain effective against the most armoured ships in the game.

Vehicles equipped with this weapon

General info

The Type 93 Model 1, Mod 2 torpedo has a diameter of 610 mm, a length of 9 m, and weighs 2,700 kg. Without the Torpedo Mode modification installed, it can travel at a maximum speed of 91 km/h for 20.00 km. With it installed, the maximum range is increased to 28.00 km, but the maximum speed is reduced to 74 km/h.

Effective damage

The Type 93 Model 1, Mod 2 torpedo carries 490 kg Type 97 warhead, which is equivalent to 627.2 kg TNT. This makes it one of the most powerful torpedoes in the game, behind only the Type 93 Model 3 and Mk.16. A single hit is usually enough to sink destroyers and can cripple or even sink cruisers, depending on where it hit.

Comparison with analogues

The other version of the Type 93 torpedo in the game, Type 93 Model 3, has a considerably larger warhead, 998.4 kg TNT equivalence, though this comes at the cost of having a maximum range that is 5 km less, at 15 km. The maximum speeds of both torpedoes are the same. The Torpedo Mode modification is not available for the Type 93 Model 3.

Besides the Type 93 Model 3, one other torpedo has a larger warhead is the Mk.16 torpedo, which has a 915.2 kg TNT equivalent warhead. However, the Mk.16 can only travel at a maximum speed of 85 km/h for only 6.4 km. In terms of maximum range and speed, there are several notable torpedoes: the Seal DM2A1 torpedo, the 53-39 torpedo, and the Type 89 torpedo. The Seal DM2A1 torpedo matches the Type 93 Model 1, Mod 2 in range, but it can only travel at 61 km/h and only has a 250 kg TNT equivalent warhead. The 53-49 torpedo has a slightly higher maximum speed, 94 km/h, but it has a smaller warhead, 317 kg TNT equivalence, and can only travel for 4 km. Finally, the Type 89 torpedo actually surpasses the Type 93 Model 1, Mod 2 quite substantially in both maximum range and speed, 38 km and 102 km/h respectively; however, it has a smaller warhead, only 267 kg TNT equivalence.

Compared to common torpedoes mounted on destroyers and cruisers among other nations:

  • Mk.15 (533 mm): The Mk.15 has a lower maximum range (5.5 km), has a lower maximum speed (83 km/h), and has a smaller explosive mass (224 kg TNT eq.). With the Torpedo Mode modification installed, the Mk.15 has a lower maximum range (9.15 km) and has a lower maximum speed (62 km/h).
  • G7a (533 mm): The G7a has a lower maximum range (6 km), has a lower maximum speed (81 km/h), and has a smaller explosive mass (358.4 kg TNT eq.). With the Torpedo Mode modification installed, the G7a has a lower maximum range (14 km) and has a lower maximum speed (56 km/h).
  • G7e (mod. T5a) (533 mm): The G7e has a lower maximum range (8 km), has a lower maximum speed (41 km/h), and has a smaller explosive mass (256 kg TNT eq.). With the Torpedo Mode modification installed, the G7e has a lower maximum range (16 km) and has a lower maximum speed (24.3 km/h).
  • 53-38 (533 mm): The 53-38 has a lower maximum range (4 km), has a lower maximum speed (82 km/h), and has a smaller explosive mass (300 kg TNT eq.). With the Torpedo Mode modification installed, the 53-38 has a lower maximum range (10 km) and has a lower maximum speed (56 km/h).
  • Mk.V (533 mm): The Mk.V has a lower maximum range (9.6 km), has a lower maximum speed (74 km/h), and has a smaller explosive mass (305 kg TNT eq.). With the Torpedo Mode modification installed, the Mk.V has a lower maximum range (12.35 km) and has a lower maximum speed (46 km/h).
  • Mk.IX (533 mm): The Mk.IX has a lower maximum range (9.6 km), has a lower maximum speed (67 km/h), and has a smaller explosive mass (340 kg TNT eq.). With the Torpedo Mode modification installed, the Mk.IX has a lower maximum range (12.35 km) and has a lower maximum speed (56 km/h).

Usage in battles

One useful feature of the Type 93 Model 1, Mod 2 torpedo is that on all ships that carry them, 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 this does limit the number of torpedoes the ship can send at once, the total amount of torpedoes is often much more than what destroyers and cruisers of other nations can carry. This is 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 the torpedoes launchers to effectively have a faster rate of fire, since the torpedo launchers will refill faster than the standard AB torpedo reload.

Be aware though that having extra torpedoes means that the ship essentially has above-deck, unarmoured ammo racks which can destroy the entire ship if detonated. These racks are, of course, emptied as their torpedoes are used to refill the launchers, so it might be a good idea to launch off at least enough torpedoes to empty the racks right away after spawning in. Unlike other torpedoes and fortunately for the Type 93 Model 1, Mod 2, its unique combination of both a large maximum range and a fast top speed make such strategies viable. By firing a wide salvo at the beginning of the match towards areas where many enemy ships are likely to be pass through (for example, capture points or narrow passes), these sections of the map can effectively be blocked off, and, because of their range and speed, they can catch enemies off-guard who either don't expect seeing torpedoes so early in the match or don't expect seeing torpedoes in areas of the map where other torpedoes usually fail to reach. The Type 93 Model 1, Mod 2 is a particularly useful weapon in the Encounter game mode. The 20 km maximum range is more than enough to reach across the entire map, which usually spans roughly 15 km. Ships armed with the Type 93 Model 1, Mod 2 torpedoes can strike the enemy team's AI convoy immediately from spawn.

For the reason that the maps are simply too small, there is no reason to use Torpedo Mode modification in random battles as the increased range doesn't provide any real benefits at the cost of speed being lowered to average levels. However, the Torpedo Mode modification should be used in naval Enduring Confrontation with its much larger maps and longer match times. In this mode, the strategical value of having a longer range is more than the tactical value of having more speed.

Pros and cons

Pros:

  • Very large explosive mass, third-largest in the game
  • Very high top speed, one of the fastest torpedoes in the game
  • Very long range, tied for second-highest in the game
  • Ships that carry Type 93 Model 1, Mod 2 often carry a large amount, upwards of 16

Cons:

  • Ships that carry Type 93 Model 1, Mod 2 torpedoes 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 war with the US or engage them in a massive battle as there would always be more US ships than Japanese ships. To combat this disadvantage, the Imperial Japanese Navy developed a strategy in which a 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 torpedoes in the past. The use of oxygen as an oxidizer, while very efficient, is also extremely dangerous, and, after casualties from premature explosion, development halted. It was in the wake of the new British battleship HMS Rodney, which carried oxygen torpedoes, that interest renewed in Japan. Taking inspiration from HMS Rodney's torpedoes, development began again in 1928 for a long-range, wakeless oxygen torpedo.

The resulting torpedo, the Type 93 Model 1, Mod 1 torpedo, referred to as Sanso Gyorai (酸素魚雷, "oxygen torpedo"), entered service in 1935. The Type 93 torpedo had a diameter of 610 mm (24 inches), was 9 meters (29 feet, 6 inches) long, weighed 2700 kg, and, being a 24-inch torpedo, was rather large compared to its contemporaries, most of which were 21-inch torpedoes. Many torpedoes of the time used combustion engines for propulsion with compressed air as the oxidizer. In contrast, the Type 93 torpedo utilized pure, compressed oxygen as its 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 efficiency 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, 490 kg of Type 97 explosive, without sacrificing fast speeds or long range.

However, this was not without its drawbacks: the torpedo was prone to early detonation. To counter this, a secondary compressed air tank was used at launch, only 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. Most notable is the case of the light cruiser Suzuya, which had its Type 93 torpedoes detonate from a near-miss air attack, sinking the entire ship.

During WWII, Japanese light forces used the Type 93 torpedo in night attacks against Allied shipping, where the stealthy torpedo could often find its target before the enemy was even aware that there was a torpedo attack underway. This, combined with the extreme secrecy of the torpedo, resulted in the loss of many Allied ships and false attributions to some sinkings. After the war, the Type 93 torpedo was dubbed "Long Lance" in the west.
