INS Kiltan is an anti-submarine warfare corvette of the Indian Navy built under Project 28. It is the third of four Kamorta-class corvettes under various stages of induction with the Indian Navy. The ship was built by the Garden Reach Shipbuilders and Engineers, Kolkata, and launched on 26 March 2013. Kiltan represents a leap forward in the Navy's attempts at indigenisation with as much as 90% of its content drawn from India itself.
