The tank had an extremely low profile, with a crew of two which sat in an isolated compartment in the turret. The main armament was a 125 mm rifled missile launcher, with a maximum range of 4 km for the "Rubin" anti-tank guided missiles, and 9 km for the "Bur" surface-to-surface missiles. It had a rate of fire of 4-5 rounds/min for the "Rubin", and 8-10 rounds/min for the "Bur". Both munitions were guided by an infra-red beam. The "Rubin" anti-tank missiles were capable of penetrating 250 mm of armor at 60° at a range of 4 km.
The Object 775 used the same engine and transmission from T-64 tank. The Object 775T (Объект 775Т) variant used two gas turbine engines instead of the diesel engine.
The prototype tank wasn't adopted for a number of reasons. The crew had poor visibility over the battlefield, the overall complexity of the design, and the low reliability of the missile guidance system.
