The STB-1 is a Japanese tier 10 medium tank.
In the early 1960s, Mitsubishi started development of a new tank that complied with government requirements for armament and defense. The first two prototypes of the STB-1 were manufactured in September 1969 for trials. In 1970 the prototypes were shown to journalists and participated in a military parade.
The STB-1 is a prototype of well-known Japanese Type 74 main battle tank. It marks the end of the Japanese Medium Tank line, it is a fast semi-accurate medium tank with low but well sloped armor, very high DPM and high penetration, making it excel as a support tank.
In patch 1.5.1, the STB-1 received a much-requested special feature; the hydropneumatic suspension system, which was previously exclusive to the Swedish high tier mediums. This allows the STB-1 to use nearly any hull-down position in the game.
The STB-1 marks the end of its Japanese medium line.

Player Opinion
Pros and Cons
Pros:
- One of the highest DPM values in the game for a medium tank
- Good turret face armor
- Good gun depression which can be further improved with hydraulic suspensions
- Great acceleration and agility, excellent reverse speed
- Good hitpoint pool
Cons:
- Fairly subpar accuracy at range
- Not counting the turret face, the rest of the tank is very poorly armored
- Crew and internal modules are very prone to injury/critical damage
- Camouflage is subpar for a medium tank
- Forward top speed is average at 50 km/h
Performance
The STB-1 is similar to the previous tanks in the line, with the exception that it now has much better turret armor than the tanks before it. It can reliably hull down unlike its predecessors due to a much needed increase in turret armor.
While the STB-1 no longer has the highest DPM the tier 10 medium tanks, having given up that spot to the K-91, it still remains a significant threat on the battlefield, with a blistering rate of fire rivalling that of the 100mm armed tier 10 Soviet mediums. The STB-1's excellent rate of fire combined with a reasonable 360 alpha damage allows the STB-1 to perma-track most opponents, allowing one to farm free damage at little to no risk to themselves. In addition to its excellent gun, in patch 1.5.1 the STB-1 recieved the hydropneumatic suspension system along with buffs to the turret armouring, allowing it to take advantage of almost any hull-down position. With its 14 degrees of gun depression when using its hydropneumatic suspension to the fullest, the STB-1 currently possesses the highest gun depression of any tier 10 tank, however one should keep in mind that the hydropneumatic suspension is only capable of tilting the tank's hull up and down and not side to side, meaning that when aiming to the sides you will only be able to use the 8 degrees of gun depression provided by the turret.
The tank itself is very small and as a result has a good camouflage factor and is also relatively mobile. While its camouflage and mobility are not on the levels of a Soviet medium such as the T-62A, they are still above average for their class. When exposing the STB-1 to enemy fire, one should keep in mind that the driver is often killed by penetrations to the front hull, and also that the ammorack sits beside the driver at the front of the tank as well.
However, while it is a menace at medium to close range when hull down, the STB-1 performs poorly at long range. With its relatively low shell velocity (1,185 m/s) and accuracy, hitting fast moving targets or weakpoints at long range is a challenge.
Last to note, while the turret is strong frontally, it has a relatively large cupola and is not impervious to high penetration premium rounds. While it can reliably bounce standard rounds from tier 10 medium tanks, premium rounds and tier 10 tank destroyers can pen the flatter parts of the turret face ocasionally if aimed carefully. Use your agility and rock back and forth to make your cupola and weaker areas of your turret harder to hit, and avoid relying on the turret armour to deflect a well aimed shot from a tier 10 tank destroyer.

Historical Info
The first prototype, designated STB-1, was delivered in late 1968 and underwent a number of modifications until 1969. The autoloader proved too complex and expensive, and was removed, additionally the remote controlled anti-aircraft machine gun was removed. The design of the turret was also changed, becoming longer. These changes resulted in the STB-3, which was delivered in 1971. The final prototype designated STB-6 was delivered in 1973. Production finally started as the Type 74 in September 1975, with 225 being delivered by January 1980. Production ended in 1989, with total production running to 893 examples.
In service, the tanks were updated with the addition of infra-red imagers (not image intensifiers) for the commander and gunner, and a laser rangefinder in the commander's cupola. The gunner's position included a digital fire control computer, fed range data from the commander's range finder. Rounds for the main gun were upgraded from HEP to APFSDS and HEAT-MP.
The Type 74 tank has the Mitsubishi 10ZF Model 21 10-cylinder two-stroke cycle diesel engine providing 750 hp (560 kW). At 19 hp/tonne, its power-to-weight ratio is similar to the French AMX-30. The maximum quoted road speed of the Type 74 is 53 km/h but its top speed is at least 60 km/h.
The Type 74 was generally outdated even before it entered service. The Type 90 was to have replaced it outright, but with the ending of the Cold War these plans were scaled back. In 1993 four Type 74's were improved to the new Type 74 Kai (改) [Type 74 mod G (G型)] standard, adding a passive infrared camera, side skirts, and so on. The upgrade proved to be extremely expensive, and the program was dropped.

Historical Accuracy Errata
The STB-1 had an autoloader. In WoT, it more closely resembles the follow-up STB-3 which lacked that feature.
- Its actual gun elevation and depression were increased from doctumented for balancing reasons.
- Its actual gun elevation and depression in normal mode is +9/-6.
- Its actual gun elevation and depression with hydraulic mode is +15/-12.
