Based on the TR-77-580 (Romanian-built version of the Soviet T-55 tank), the TR-85 tank was developed from 1978 to 1985 and produced from 1986 until 1990. A modernization program was initiated in March 1994 in order to upgrade the TR-85 tanks to NATO standards. The result was the TR-85M1 main battle tank, currently the most modern tank in service with the Romanian Land Forces. Although a further development of the T-55, the TR-85M1 uses a T-block powerpack (similar to the one used in the Leopard 1) based on a V8 German 830 hp diesel engine, an improved turret, a locally-designed "Ciclop" fire control system (with cross-wind sensor, laser rangefinder and night vision), new 100 mm BM-412 Sg APFSDS-T projectiles and a completely redesigned suspension with 6 road wheels on each side, protected by metal side skirts. Combat weight is 50 tons.

text: Main battle tank A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the armor-protected direct fire and maneuver role of many modern armies. Cold War-era development of more powerful engines, better suspension systems and lightweight composite armour allowed a tank to have the firepower of a super-heavy tank, armor protection of a heavy tank, and mobility of a light tank all in a package with the weight of a medium tank. Through the 1960s, the MBT replaced almost all other tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles.
