Russian Main Battle Tank T-90A

The major difference lies in the turret... while the initial T-90 (Object 188) was little more than a glorified T-72B growing out of the whole Object 188-buisness, the T-90A variant essentially introduced some more advanched elements to rectify faults recognized early on in the T-90. Main diference is the new welded turret giving enhanced resistance due to improved materials. Fire-control and ammunition-capabilities were also enhanced together with better sights and lastly an improved V-94S2 engine giving about 1000hp. The improvements came along and partly grew out of the Indian T-90 contracts, where the cast turret and 1000hp engine were introduced to the T-90 Bishma... that´s the basics of it, if I remember correctly
