KAVARATTI: Fourth Ship of Project-28 Launched
May 21, 2015

The Fourth Anti Submarine Warfare (ASW) Corvette of Project-28, named ‘Kavaratti’, was launched on 19 May at Garden Reach Shipbuilders and Engineers Ltd (GRSE), Kolkata. This is the excellent work done by the yard for contributing towards achieving Indian Navy’s dream of transforming itself from a Buyers Navy to Builders Navy.

What is Project-28?

  • The four ships of Project-28 built by GRSE have been designed indigenously by the Directorate of Naval Design, New Delhi and bear testimony to the acclaimed legacy of Naval Designers.

  • The ships have been constructed using high grade steel (DMR 249A) produced in India.

  • With a displacement of 3300 tonnes, the sleek and magnificent ASW Corvettes span 109.1 meters in length and 13.7 meters at the beam.

  • They are propelled by four diesel engines to achieve speeds in excess of 25 knots and have an endurance of more than 3000 Nautical Miles.

  • The P-28 corvettes also boast of "firsts" such as the revolutionary Rail-less Helo Traversing System, Foldable Hangar Door, use of Personnel Locator System and use of Carbon Fibre Reinforced Plastic (CFRP) Superstructure integrated with the Steel Hull in the third and fourth ships of the Class.

  • These ships have common raft mounted Gear Box and Diesel Engines, which give the vessels very low radiated underwater noise.

  • This is well complemented with an efficient propeller with very high cavitation inception speed.

  • The P-28 Ships also have Total Atmospheric Control System (TACS) and an Integrated Platform Management System (IPMS) which include Integrated Bridge System as well as Battle Damage Control System.

  • The ASW Corvettes also incorporate new design concepts for improved survivability, sea keeping, stealth and manoeuvrability.

  • Enhanced stealth features have been achieved by including Low Radar Cross Section (RCS) signature through full beam superstructure, inclined ship sides and reduced Infra Red (IR) signature by use of Infra Red Suppression System (IRSS) device for cooling the Engine and Diesel Alternator exhausts.

  • The ships are also equipped to carry and operate one multiple role helicopter. 

Kavaratti will also be packed with an array of state of art weapons and sensors, including a Medium Range Gun (from Bharat Heavy Electrical Ltd), Torpedo Tube Launchers as well as Rocket Launchers (from Larsen & Tubro), Close-In Weapon System (from Gun and Shell Factory) and Chaff System (from Machine Tool Prototype Factory).
