Third anti-sub­ma­rine war­fare corvette for In­dian Navy launched

SP's MAI - - FRONT PAGE -

The third anti-sub­ma­rine war­fare (ASW) corvette for the In­dian Navy de­signed un­der Project-28 (P-28) by the Navy’s Di­rec­torate of Naval De­sign, be­ing built by one of In­dia’s lead­ing ship­builders, the Garden Reach Ship­builders and Engi­neers Ltd. (GRSE), was launched in Kolkata, on March 26, 2013.

Named af­ter an is­land – Kil­tan – in the Laksh­wadeep ar­chi­pel­ago of In­dia, the ASW corvette was launched by Chi­tra Joshi from GRSE main­yard in the pres­ence of Chief of the Naval Staff, Ad­mi­ral D.K. Joshi, Chair­man and Man­ag­ing Di­rec­tor, GRSE, Rear Ad­mi­ral (Retd) A.K. Verma and other of­fi­cials from the Min­istry of De­fence, armed forces and West Ben­gal ad­min­is­tra­tion.

With nearly 90 per cent indi­geni­sa­tion con­tent aimed to be achieved in the man­u­fac­tur­ing of the ship, the ef­forts made by the In­dian Navy and de­fence ship­yards to­wards the na­tional goal of indi­geni­sa­tion and self-re­liance got a ma­jor im­pe­tus with this lat­est ASW corvette launch.

Laud­ing ef­forts of GRSE in de­tail de­sign­ing of the ship, the Navy Chief sin­gled out its tech­no­log­i­cal land­mark, as be­ing the first ship in the coun­try built with a com­pos­ite su­per­struc­ture. The su­per­struc­ture made of car­bon fi­bre com­pos­ite ma­te­rial has been suc- cess­fully in­te­grated with the main hull of the ship. Be­sides re­duc­ing the top weight, it will pro­vide im­proved stealth features and re­duce life-cy­cle main­te­nance costs.

The ship’s hull form is highly ef­fi­cient with ex­cel­lent sea-keep­ing and ma­noeu­vra­bil­ity char­ac­ter­is­tics hav­ing an over­all length of 109 me­tres. The ship can cut through the sea at a very high speed of 25 knots. Hull of the ship is built with war­ship grade high ten­sile in­dige­nous steel.

The ship’s ad­vanced stealth features will make it less sus­cep­ti­ble to de­tec­tion and help in ef­fec­tive de­ploy­ment of soft kill mea­sures. The ships will be fit­ted with com­plete in­dige­nous state-of-the-art weapons and sen­sors, in­clud­ing a medium-range gun, tor­pedo tube launch­ers, rocket launch­ers and close-in weapon sys­tem.

Th­ese ships are also equipped with a bow-mounted sonar and are ca­pa­ble of de­ploy­ing a heli­copter, adding con­sid­er­able punch to the ship’s anti-sub­ma­rine ca­pa­bil­ity. Th­ese ships also fea­ture an ad­vanced in­te­grated plat­form man­age­ment sys­tem for con­trol­ling and co­or­di­nat­ing the propul­sion, aux­il­iary and power gen­er­a­tion equip­ment.

The new P-28 ASW corvettes also mark many firsts in­clud­ing in­tro­duc­tion of the ‘rail-less helo travers­ing sys­tem’ to han­dle a heli­copter on board the ship, fold­able hangar door, use of in­dige­nous DMR 249A steel and car­bon fi­bre re­in­forced plas­tic (CFRP) su­per­struc­ture in­te­grated with the steel hull of the ship.
