A CGI of CSL's proposal for India's ASW corvette program. GRSE has unveiled a similar design

Two companies shortlisted for the Indian Navy’s 16-ship anti-submarine warfare shallow water craft (ASWSWC) program have unveiled imagery of their respective proposals at DefExpo India 2018, held in Chennai from 11 to 14 April.

The program calls for a 70 m water-jet-powered corvette that displaces 700 tonnes and can be deployed for maritime security, coastal anti-submarine warfare (ASW), and minelaying operations.

Cochin Shipyard Limited (CSL) and Garden Reach Shipbuilders & Engineers (GRSE) emerged as the two lowest bidders in the program, and as such, production for the program would be evenly split between the two companies based on the lowest bidder’s cost.
