MBT's!

The Type 90 tank (90???, Kyu-maru-shiki-sensha) is a main battle tank (MBT) of the Japan Ground Self-Defense Force (JGSDF). It was designed and built by Mitsubishi Heavy Industries as a replacement for the Type 61 and to supplement the then current fleet of Type 74 tanks, and entered service in 1990.

history:

After the adoption of the Type 74, the Japanese High Command was already looking for a superior, completely indigenous tank design to defeat the Soviet T-72. As a result, development of a prototype, the TK-X MBT began between 1976 and 1977. Joint development was performed by Mitsubishi Heavy Industries and TRDI (Japan Defense Agency's Technology Research and Development Institute). Major subcontractors included Japan Steel Works, Daikin Industries, Mitsubishi Electric, Fujitsu and NEC.[citation needed]

A first series of two prototypes of the Type 90 were developed, both armed with a Japanese 120 mm smoothbore gun (produced by Japan Steel Works Limited) firing Japanese ammunition (produced by Daikin Industries Limited).[1] The first prototype (TK-X-0001) was completed by 1982, and underwent testing shortly after. Following the first tank's completion, development began on the second prototype (TK-X-0002), until it was completed by June 1985, after experiencing delays. Testing and design modifications such as improvements to the turret and half modular type ceramic composite armour were conducted starting in October 1983, and continued until October 1986.
