Object (Ob'yekt \ Объект) 490 circa 1989-1991.
Also known as "Boxer" or "21st Century Tank" (Перспективный танк 21го века).
Armed with 152mm LP-83 cannon, two twin-barrel TKB-666 7.62mm machineguns (on the sides of the turret) and an AGS-30 grenade launcher in its separate mount.
Only few photos of the vehicle exist in public domains, as well as a couple of schematics.
Obj. 490 could be described as a continuation of Obj. 477 development of a conceptually new MBT, completely straying from the traditional tank scheme.
Work on the project was suspended due to the collapse of the USSR. At least one prototype was known to exist in KhKBM design bureau, fate unknown.
