The Object 490A was created as an alternative variant for the Object 490. The 490A Buntar was suggested in order 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 to be a vehicle ahead of its time, as it utilized multiple new technologies in order to stay ahead of the competition.
