GS Paper - 3 (Defence)

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

What is a Corvette?

  1. A Corvette is the smallest class of naval ships and it falls below the warship class of a frigate.
  2. These are highly agile ships and are categorised as missile boats, anti-submarine ships, coastal patrol crafts and fast attack naval vessels.
  3. 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.
  4. However, these were powered by sails and masts, and disappeared for a while when steam powered naval ships made their appearance.
  5. 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.
  6. The Indian Navy at present has the Kamorta Class Corvettes, which are also known as Project 28.
  7. These ships have an anti-submarine role and are manufactured at Garden Reach Shipbuilders and Engineers in Kolkata.
  8. 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.
