History
In 1986, the Cabinet Committee on Political Affairs (CCPA) decided to diversify India's warship building capability, and start an alternate production line to the Godavari class frigates that were built at Mazagon Dock Limited (MDL) in Bombay. 3 additional Godavari class frigates were to be built at Garden Reach Shipbuilders and Engineers (GRSE) in Calcutta. After a transfer of technology from MDL to GRSE, production was to start in 1988, with deliveries between 1993 and 1996.However, as the production was about to commence, the Indian Navy's requirements were revised, which led to frequent changes in the design. The re-designed ship, christened Project 16A, had its General Arrangement Drawings finalized only in Sep 1994.[1]
Design
The basic design of the ship was proposed by Indian Navy's Directorate of Naval Design. The detailed design development was undertaken by GRSE.The ships were originally designed to be fitted with the Trishul SAM, but in 2001, the decision was made to deploy the Barak SAM.
The ship is propelled by 2 BHEL Bhopal 15000 BHP steam turbines.[2]
Times of India reported on 07 September 2005, that INS Betwa became the first first Indian warship to successfully integrate indigenous combat data systems, with a wide variety of foreign/Indian weapons and sensors onboard. While INS Brahmaputra was the first warship to be equipped with the BEL combat data systems, it is INS Betwa that has validated the indigenous technology platform. Captain C S Murthy, CO of INS Betwa, stated that the integrated systems have been successfully tested to an extreme. The anti-submarine warfare officer of INS Betwa, Lieutenant Commander Sharad Parti, stated, "The EMMCA system gives commanders on the ship a consolidated tactical picture. It adds to the ship's maritime combat power." Commodore R P S Ravi, Director of the Maritime Warfare Centre in Mumbai, stated that it was a significant achievement for the Navy that indigenous data systems would be used for target evaluation, weapon selection and target engagement.
