The Type T-51b is a rank II Japanese motor torpedo boat with a battle rating of 2.3 (AB/RB/SB). It was introduced in Update 1.89 "Imperial Navy".
Survivability and armour
Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armament separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips for preserving survivability in the "Use in battle" section.
If necessary, use a graphics template to show the most well-protected or most vulnerable points in the armour.
Write about the ship’s mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward speed and reverse speed.
Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells.
Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.
Torpedoes launchers are standard equipment on many ships and boats. Torpedoes are a significant means of defeating an opponent. Evaluate the position of the torpedo launchers, discuss the ammunition available, firing specifics such as dead zones, features of the torpedoes themselves, etc.
Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can take an off-guard opponent by surprise. Evaluate the ammunition of this type of armament and rate its performance in combat.
Usage in battles
Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don’t try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).
Pros and cons
- 4 x torpedoes facing in a forward direction
- Decent speed to move around the map rather quickly
- Gun has excellent rotation speed
- Rear gun does not fire in a forward direction, only to the side and rear of the boat
The Type Ko MTB (甲型魚雷艇, T-51) is a Japanese large MTB inspired by the German S-boots.
This boat is separated into two group: No.10 class MTB (T-51a) and No.11 class MTB (T-51b) (Currently, the in-game model is a mix of the two classes' features).
After the completion of the No.1 class MTB (T-1), news about activity of the German Schnellboot (S-boot) from Europe reached the Imperial Japanese Navy (IJN). They started to copy the S-boot design, but they had only a simple sketch and one civilian motor boat owned by the Mitsui family built by Lürssen (a builder of S-boot). In that time, the Japanese did not have the experience to produce a wood-and-iron mixed large boat, so at first they built one prototype. ("Vessel No.600", later No.10 MTB)
The No.600 prototype was laid down in July 1942 by Yokohama Yacht Tsurumi factory and completed in November 1943. But because of the worsening of the war situation, they started mass-production the ship design before testing the prototype. Just afterwards, the Japanese receive official detailed drawings of 95-ft type S-boot. Basically, design of future T-51 and S-boat was similar, but there was much for the Japanese to learn.
In the designing of No.600, the Japanese simplified lots of part and material. Due to how well-crafted the S-boot design was, the simplification caused several problems. Though measures were taken to mitigate the problems, the vessel stability was not enough and so there were difficulties putting the ship into practical use.
No.600 was equipped with four Mark 71 Model 6 engines (water-cooled, 920 HP), which were a copy of the Italian MAS-451 MTB engines. There were two shafts, with two engines connected to one shaft by Vulkan coupling. However, this configuration caused an increase of weight and so the prototype exceeded the planned displacement of 84.2 tons, and instead reached 89.6 tons and so the maximum speed decreased. Because of this, the boat was redesigned into the No.11 class MTB, which eliminated the coupling and so each engine had their own shaft. With this, the single No.10 class design (No.600 prototype) was named the T-51a, with the redesigned No.11 class as the T-51b that would be the model for subsequent boat numbers.
Armaments was also redesigned between the two class. The T-51a had one 25 mm twin machine gun and four 45 cm torpedoes, while the T-51b had three 25 mm single machine guns and two torpedoes.
No.10 (T-51a), No.13 and No.16 were built at Yokohama Yacht Tsurumi factory, while the other boats were built by a new shipyard, Yokohama Yacht Choshi factory. A total of ten Type Ko MTBs were laid down, but only 8 boats were completed (No.10 - No.17). Construction of Type Ko was cancelled in August 1944. No.18 was planned to equip a small diesel engine, but it was not completed. The construction of Type Ko MTBs was delayed because the No.11 class MTBs need to resolve problem discovered during the testing of No.10 class MTB. Also the Mk.71 Mod.6 engines required advanced manufacturing technology and so production of engine was also delayed.
No.10 MTB was dispatched to Truk island just after completion, but a fire broke out and sank due to air raid. No.12 MTB was brought out from Choshi to Yokosuka to equip weapons, but just after that was completed, she sunk due to an electric motor spark that ignited the gasoline and subsequently exploded.
Other vessels was deployed to the Special Attack corps, but most of them did not experience the actual battle. Only one boat deployed at Habu port of Izu Oshima attacked an enemy submarine.
