The Obiekt 277 (Объект 277) was a prototype Soviet heavy tank designed in 1957, one of the last heavy tanks to be produced by the USSR.[1] Developed alongside its sister design, the Obiekt 278, as well as the Obiekt 279 and the Obiekt 770, Obiekt 277 was a conventional heavy tank, armed with a powerful gun and thickly armoured. All development was cancelled in 1960, as part of Nikita Khrushchev's wish to abandon what he deemed obsolete heavy tanks, and re-focus efforts on ATGMs.[2]
