History and Design of the INS Kavaratti
The Ship was designed by Kolkata-based Garden Reach Shipbuilders and Engineers. Built at an estimated cost of ₹1,700 crores, the ship takes its name from the capital of the Union Territory of Lakshadweep. It is the successor to the erstwhile Arnala-class corvette of the same name which participated in Operation Trident during the Indo-Pak war of 1971 (December 3 – 16, 1971). The Arnala-class INS Karavatti was decommissioned in 1986
The INS Karavatti is the last of four Kamorta-class corvettes under various stages of induction with the Indian Navy.
The other three Kamorta-class corvettes are:
- INS Kamorta
- INS Kadmatt
- INS Kiltan.
The INS Kavaratti was built and designed by the Indian Navy’s Directorate of Naval Design. It has capabilities to fight in a nuclear, biological and chemical environment backed by advanced stealth features and a low radar signature which boosts its anti-submarine warfare capabilities. The ship will be operated by a complement of 10 officers and 106 sailors.

What is Anti-Submarine Warfare (ASW)
Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, and/or destroy enemy submarines. Such operations are typically carried out to protecting friendly shipping and coastal facilities from submarine attacks and to overcome blockades.

Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine.
Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances of unrestricted submarine warfare and the introduction of submarine-launched ballistic missiles, which greatly increased the perceived lethality of submarines.
