Why it is in news?

• The country is rapidly marching towards indigenisation and the commissioning of the third Kamorta class Anti-Submarine Warfare (ASW) stealth corvette is a classic example of that.
• Defence minister commsioned INS KILTAN. 

INS KILTAN

• INS Kiltan (P30) 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 localisation with as much as 90% of its content drawn from India itself 

Tough steel

• INS Kiltan has been constructed using high grade steel (DMR 249A) produced by the state-owned Steel Authority of India Limited (SAIL).
•  It has a displacement of 3500 tonnes, spans 109 meters in length and 14 meters at the beam and is propelled by four diesel engines to achieve speeds in excess of 25 knots with an endurance of 3450 nautical miles.
• The carbon composite material gives it an extra stealth edge and also lowers the top weight and maintenance cost.
• The installed propulsion and auxiliary systems provides very low radiated underwater noise feature, required for anti-submarine warfare.
• The enhanced stealth features include ‘X’ form of Hull, full beam superstructure, inclined ship sides and use of Infra Red Signature Suppression (IRSS).
