India's most numerous main battle tank — a licensed production variant of the Russian T-90S with significant Indian upgrades and localisation. Named "Bhishma" after a warrior from the Mahabharata, the Indian T-90S/Bhishma features French Catherine-FC thermal imaging, Israeli ELOP TSGS gunner sight, Kanchan composite armour developed by DRDO for the frontal arc (replacing Russian Kontakt-5 ERA in later batches), and air conditioning for desert operations (critical for the Thar Desert deployment). Armed with a 125mm 2A46M smoothbore gun with autoloader, firing APFSDS, HEAT, and HE rounds plus the 9M119 Refleks gun-launched anti-tank missile (5 km range). Powered by a V-92S2 diesel producing 1,000 hp. Weight of 46.5 tonnes. India has produced over 1,500 T-90S tanks under licence at Heavy Vehicles Factory Avadi, making it the largest T-90 fleet outside of Russia. The T-90MS variant features further upgrades including Relikt ERA and improved fire control.
- Proven reliable platform with large Indian fleet (1,000+ T-90 series)
- 125mm smoothbore gun fires gun-launched ATGMs (Invar/Refleks)
- Shtora-1 DIRCM active defense reduces ATGM guidance accuracy
- Lighter than Arjun (46t vs 68t) — better strategic deployability
- Russian supply chain creates wartime dependency risks under sanctions
- Cramped crew compartment with autoloader ammunition in vulnerable carousel
- Thermal imaging and electronics lag behind Western MBTs
- Kontakt-5 ERA effective vs. older ATGMs but less so vs. tandem warheads
