1977 Soviet T54M Main Battle Tank

The T-54M (Obiekt 137M) was a major Soviet modernization program introduced in 1977 to upgrade aging T-54 main battle tanks to the operational standards of the newer T-55 series. The upgrade replaced the original drivetrain and internal systems, integrating the V-55 engine, modern radio equipment, and upgraded night vision sights for the commander and gunner. Crucially, the modernization added the stabilized 100 mm D-10TG main gun and expanded internal ammunition storage, significantly extending the service life of the battle tank within Soviet reserve units and Warsaw Pact inventories through the late Cold War.
