The Obiekt 490A "Rebel" (Russian: Объект 490А Бунтарь), or Object 490A, was a Soviet experimental main battle tank developed between 1981 and 1982. Only two prototypes were ever produced, neither of which was capable of firing due to time constraints. Neither of the vehicles was completed before their production was ceased. Object 490A was created as an alternative variant for the Object 490. The 490A Buntar was suggested to provide the vehicle with one more crew member as well as an externally mounted gun. The biggest change from the Object 490 to the 490A was the completely redesigned turret as well as minor changes to the chassis. The project was cancelled at the end of 1984 due to the newer Object 477 Molot program beginning. The tank is considered a vehicle ahead of its time, as it utilized multiple new technologies to stay ahead of the competition. The armor consisted of a layer of steel followed by composite armor, which consisted of five layers of steel separated by four layers of ceramic. The roof armor was unusually high on the hull as well as the turret in order to prevent the vehicle from being damaged by artillery.
