The Obiekt 775, or Object 775 (Объект 775), was a Soviet experimental missile tank built in 1964.

The tank had an extremely low profile, with a crew of two which sat in an isolated compartment in the turret.

The "Rubin" anti-tank missiles were capable of penetrating 250 mm of armor at 60° at a range of 4 km.

The prototype tank wasn't adopted for a number of reasons.

These included the crew having poor visibility over the battlefield, the overall complexity of the design, and the low reliability of the missile guidance system.
