In 2005 the Russian army resumed delivery of the T-90, requesting the "original" specification for the vehicle with a cast turret. But with the new order numbering a paltry 14 tanks, and the large capital investment required to set up production of new cast turrets, the Russian Ministry of Defence agreed on a new configuration very close to the Indian T-90S, which was expeditiously accepted into service without any trials as the Object 188A1 or T-90A. That same year saw delivery of an additional 18 new tanks - enough to equip approximately five tank platoons. These new Russian tanks were powered by the V-92S2 engine, carried a T01-K05 "Buran-M" gunner's sight (passive-active night-vision channel with an EPM-59G "Mirage-K" matrix and a maximum observation distance of 1,800 m) and were protected by the most recent Kontakt-5 reactive armor with 4S22 explosive tiles.
