In July 2006, the Indian government announced that Russia would build 3 “stealth warships” for India under a Rs 5114 crore (INR 51.14 billion, then about $1.1 billion) contract signed in New Delhi. The contract actually covers 3 modified Krivak III/ Talwar Class frigates, as a follow-on to an earlier $900 million purchase in 1997.
The Krivak III/ Talwar Class ships like INS Tabar are not really stealth warships, esp. by comparison to more modern designs like Singapore’s new Formidable Class frigates from France (a Lafayette Class derivative). They’re best described as mid-range multi-role frigates, with some stealth features and a potential emphasis on anti-submarine work. By mid-2013 they had all been commissioned by the Indian Navy.
