First two ordered December 1983, two in 1985, two in April 1990 and two more in October 1994. The diesels are assembled in India under licence by Kirloskar. Indigenous content of the whole ship is about 65 per cent. This class is replacing the Petyas. From Kora onwards is an upgraded version which has been slowed down by delays in the supply of Russian equipment.
Ships names are still uncertain for the last three of the class.
The reported plan was to make the first four ASW ships, and the remainder anti-aircraft or general purpose. All have fin stabilisers and full air conditioning. Jane's Information Group.
