The Defence Acquisition Council (DAC) has given the Acceptance of Necessity (AoN) for the procurement of next-generation Corvettes for the Indian Navy at an approximate cost of Rs 36,000 crore.

What is a 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.
• During World War II, the term Corvette was used to describe vessels which had anti-submarine roles assigned to them.
• Modern Corvettes can go up to 2,000 tons in displacement which helps in keeping them agile.

What kind of Corvettes does the 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.

What new capabilities will the new generation Corvettes have?

• 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.
• It is worth noting that these roles will be in addition to the anti-submarine roles being already performed by the existing Corvettes in the Navy.
• Corvettes will be constructed based on new in-house design of the Indian Navy using latest technology of ship buildings.
• They would contribute to further the government’s initiative of Security and Growth for all in the region (SAGAR).
