The Russian-made thermal imaging device not only meant that Russian tanks would no longer need to be equipped with foreign parts, but it also meant that complete tank modernization was cheaper. Furthermore, there will be no decrease in demand for the T-72 and the T-90 in the next few years. The new tank gunner’s heat-vision sight Irbis-K and the commander’s combined sighting and observation system Agat-MDT can be supplied to T-72, T-80 and T-90 upgraded versions (T-72B3M, T-80BVM, T-90M...), replacing Catherine-FC thermal camera from Thales.
