About

Corvette:

• A Corvette is the smallest class of naval ships and it falls below the warship class of a frigate.
• These are highly agile ships and are categorised as missile boats, anti-submarine ships, coastal patrol crafts and fast attack naval vessels.
• The word corvette itself is derived from French and Dutch origin.
• Corvettes date back to the 18th and the 19th century when they were extensively used in the naval warfare duels that were fought at high seas.

Corvettes that Indian Navy possess:

• The Indian Navy at present has the Kamorta Class Corvettes, which are also known as Project 28.
• These ships have an anti-submarine role and are manufactured at Garden Reach Shipbuilders and Engineers in Kolkata.
• The four Kamorta Class Corvettes that the Indian Navy possesses are named INS Kamorta, INS Kadmatt, INS Kiltan and INS Kavaratti.
• The first of these was commissioned in 2014 and the last one in 2020.
  

New capabilities of the new generation Corvettes:

• The next-generation Corvettes will be manufactured for various roles like surveillance missions, escort operations, deterrence, surface action group operations, search and attack and coastal defence.
• These roles will be in addition to the anti-submarine roles being already performed by the existing Corvettes in the Navy.
• These NGCs will be built based on a new design developed in-house by the Indian Navy, using state-of-the-art shipbuilding technologies and are expected to help promote the government’s SAGAR (Security and Growth for All in the Region) initiative.
