The INS Trikand is the third and last of the second batch of 3 frigates ordered from Russia by India in a 2006 contract worth $1.6 billion. The other two, the INS Teg and INS Tarkash were both delivered to the Indian Navy in 2012.
The second batch of the Talwar class differ from the first batch in the following:
- The second batch are armed with 8 Brahmos supersonic cruise missile instead of the 3M-54 Klub missile.
- The second batch lacks the Kashtan Close-In Weapon System (CIWS) and is only fitted with 2 AK-630M guns. Presumably, the Israeli Barak-1 will be added to the ships in the future similar to the Shivalik class.
- one 100 mm A-190 dual purpose gun
- the Shtil system with 24 9M317 surface-to-air missiles
- two dual 533 mm torpedo launchers
There have been negotiations with Russia concerning a third batch of 3 Talwar class frigates to India despite the fact that some issues had to be resolved regarding the second batch. However, no final contract has so far been signed.
