The Type 74 Ha-Go (74-gata shiki-sensha Ha-go) is a main battle tank used by the Japanese Imperial Army Corps during the latter years of the Cold War era, replacing the earlier Type 57 main battle tanks that had served both army and marines during the earlier years. The tank, similarly to it's predecssor, sported a 100mm cannon, however it was smoothbore as opposed to rifled on the Type 57. The tank, despite being developed from more or less the same basic chassis as the Type 72 fielded by the Marine Corps, was developed for the Army Corps and thus around the 100mm guns that the Army fielded as standard. The 100mm shells proved impractical to mount within a carosel autoloader without significantly compromising survivability, one major roadblock in the tank's development, and thus the autoloader had to be changed to a bustle titing-arm autoloader. While the tank would use the same powerplant and optics suite as the Type 72, in further addition, the turret ring had to be redesigned and moved further back to accomodate the larger turret housing the 100mm, the tank was heavier, thus requiring a redesigned transmission, factors which delayed it's introduction within the Army Corps for a good two years. Production would not fully commence untill well into October 1973, nearly two years later than the Marine Corps's Type 72. The first battalions of Type 74s came online in late 1974.

IMPORTANT: Within the list of weapons, there is one titled '13.2mm coaxial heavy machine gun'. This weapon serves no other purpuse than to toggle the fire control system into aiming for the coaxial wing gun that has gravityless bullet paths as opposed to the dropping trajectories of the 100mm smoothbore.
