INS Kolkata – Stealth De­stroyer

Com­mis­sion­ing the largest ever in­dige­nous war­ship, INS Kolkata into the In­dian Navy, prime Min­is­ter Naren­dra Modi said it will de­ter any­one from cast­ing their Ôevil eye on In­diaÕ. ÒINS Kolkata is an ex­am­ple of our mil­i­tary might, show­cas­ing our ca­pa­bil­i­ties to the world. In to­day’s world fight­ing and win­ning wars is less dif­fi­cult. To en­sure that there is no war, one has to have a mod­ernised and pow­er­ful mil­i­tary cou­pled with state-of-the-art weaponry so that no one can dare cast their evil eye on us,ÓModi said. Fur­ther, he added, ÒINS Kolkata is a float­ing tech­nol­ogy mar­vel. It will pro­vide se­cu­rity to those who use the sea route to carry out trade ac­tiv­i­ties.Ó

The com­mis­sion­ing cer­e­mony of INS Kolkata on Au­gust 16, 2014, was at­tended by the De­fence Min­is­ter Arun Jait­ley, the Gov­er­nor of Ma­ha­rash­tra K. Sankara­narayanan, the Chief Min­is­ter of Ma­ha­rash­tra prithvi­raj Cha­van and the Chief of the Naval Staff Ad­mi­ral R.K. Dhowan, in ad­di­tion to many other serv­ing and re­tired de­fence per­son­nel.

INS Kolkata is the lead ship of project 15A, Guided Mis­sile Stealth De­stroyer, un­til now the largest size of in­dige­nously con­structed war­ship. The other two ships of the class to follow are Kochi and Chen­nai. The ship is 164 me­tres wide and has a full load dis­place­ment of 7,400 tonnes. She is manned by 30 of­fi­cers and 330 sailors. The stealth de­stroyer has been de­signed by INÕs own De­sign Bureau, prin­ci­pal Di­rec­tor Naval De­sign (Sur­face Ship Group) and is in­dige­nously con­structed by the Mazagon Dock Ltd. Mumbai, the lead­ing de­fence ship­yard of the coun­try. INS Kolkata war­ship is a tech­nol­ogy demonstrator and will showcase a gi­ant leap of ship­build­ing tech­nol­ogy in the coun­try.

INS Kolkata is the first In­dian Naval de­stroyer to have multi func­tional ( MF) con­for­mal ar­ray surveil­lance radar - the MFS­tar to pro­vide tar­get data to long-range sur­face to air mis­sile sys­tem (LRSAM) to be de­liv­ered shortly. The MFR and LRSAM sys­tem is a joint ven­ture of the De­fence Re­search and De­vel­op­ment Or­gan­i­sa­tion (DRDO) and Is­rael Aero­space In­dus­tries Ltd. She is also equipped with the ad­vanced anti-ship sur­face to sur­face mis­siles - the Brah­Mos. The ac­tive elec­tronic tower ar­ray sonar (ATAS) is also in­stalled.

Ad­mi­ral Arun prakash, for­mer Chief of the Naval Staff, crit­i­cally eval­u­ated the com­mis­sion­ing of INS Kolkata, when he opined that KolkataÕs com­mis­sion­ing is an op­por­tune junc­ture to strike a bal­ance sheet which may help us break out of the vi­cious cir­cle of de­layed in­dige­nous projects and in­creas­ing im­port de­pen­dency.

he added, on the pos­i­tive side, the Direc­torate Gen­eral of Naval De­sign, which started in the 1960s with the mod­i­fied Leander class frigates, has over the years brought great credit for it­self by cre­at­ing

Ñ Prime Min­is­ter Naren­dra Modi a se­ries of el­e­gant, func­tional and com­bat­wor­thy war­ships of the Delhi, Shiva­lik and now the Kolkata class. The KolkataÕs de­sign claims ÔstealthÕfea­tures, which should ren­der it dif­fi­cult for the ad­ver­sary to de­tect. The INÕs Weapon and Elec­tronic Sys­tems En­gi­neer­ing Es­tab­lish­ment (WE­SEE) un­der­took the her­culean task of in­te­grat­ing the melange of Rus­sian, Is­raeli, Dutch, French, Ital­ian, and In­dian sys­tems which went into this ship. Nowhere else in the world is such a com­plex un­der­tak­ing at­tempted, but WESEEÕs en­deav­ours have been in­vari­ably re­warded with suc­cess. To WE­SEE also goes huge credit for de­vel­op­ing the elec­tronic nerve-cen­tre of the ship, its com­bat man­age­ment sys­tem or CMSÑ again a unique and ster­ling achieve­ment.

he fur­ther com­mented that show­ing em­i­nent good sense and prag­ma­tism, the

DRDO lead­er­ship agreed to the NavyÕs pro­posal for a path-break­ing tri­par­tite col­lab­o­ra­tive ar­range­ment with the Is­raelis for the de­vel­op­ment of the LRSAM. The fund­ing as well as man­power li­a­bil­i­ties were shared by the IN and DRDO. The project, in­volv­ing DRDO sci­en­tists, naval en­gi­neers and the de­fence-in­dus­try has ren­dered tremen­dous ben­e­fits to all three par­tic­i­pants and, not­with­stand­ing de­vel­op­ment de­lays, will bring the IN to front rank of navy tech­nolo­gies.

INS Kamorta – ASW Corvette

Break­ing new grounds in the in­dige­nous war­ship build­ing, the first in­dige­nously de­signed and built stealth anti-sub­ma­rine war­fare corvette (ASW), INS Kamorta, un­der project 28 was com­mis­sioned at an im­pres­sive cer­e­mony at Visakha­p­at­nam on, Au­gust 23, 2014. The ASW Corvette, the first of its kind was com­pletely de­signed on their own by the prin­ci­pal Di­rec­tor Naval De­sign (Sur­face Ship Group) and built by the de­fence ship­yard Gar­den Reach Ship­builders and En­gi­neers Limited (GRSE), Kolkata. The other ma­jor mile­stone of project 28 is that this is the first war­ship of the IN, the weapon sys­tems of which are man­u­fac­tured in the coun­try. INS Kamorta is first of the four ASW Stealth Corvettes.

The De­fence Min­is­ter, Arun Jait­ley, who com­mis­sioned INS Kamorta, de­scribed the de­vel­op­ment as Ôthe com­ing of age of our ship­build­ing in­dus­tryÕ. Ad­dress­ing the gath­er­ing he con­grat­u­lated the In­dian Navy, GRSE and other In­dian pSUs which were in­volved in the project and said that the in­duc­tion of INS Kamorta adds thrust to the na­tionÕs on­go­ing en­deav­ours of in­di­geni­sa­tion of weaponry.

“Dur­ing the past five decades, the Naval De­sign Direc­torate has con­structed 119 war­ships and sub­marines of var­i­ous cat­e­gories. Another 42 are be­ing built at var­i­ous pub­lic and pri­vate ship­yards. We have moved on from the big­gest buy­ers to man­u­fac­tur­ers of the ships as the ship­build­ing in­dus­try in the coun­try is grow­ing leaps and bounds,Óhe said. he stressed the need to strengthen In­di­aÕs wa­ter line se­cu­rity. ÔÔI am sure INS Kamorta will serve this coun­try ef­fec­tively for a very long time. Our ef­fec­tive preparedness is al­ways the best guar­an­tee for peace in this re­gion and our forces have been dis­charg­ing their duty ef­fec­tively,ÕÕhe said.

Speak­ing on the oc­ca­sion, Ad­mi­ral R.K. Dhowan, the Chief of the Naval Staff, re­called that the ear­lier ver­sion of Kamorta of the In­dian Navy was a petya class corvette ac­quired from erst­while Soviet Union and said the new INS Kamorta has been 90 per cent in­dige­nously built. ÒThe In­dian Navy is a multi-di­men­sional force. It is the re­spon­si­bil­ity of the Navy to en­sure that the In­dian mar­itime in­ter­ests which have vi­tal re­la­tion­ship with the na­tionÕs eco­nomic growth, are al­lowed to de­velop un­hin­dered,Óhe said.

Ad­mi­ral R.K. Dhowan, Chief of the Naval Staff, Vice Ad­mi­ral Satish Soni, Flag Of­fi­cer Com­mand­ing-in-Chief, East­ern Naval Com­mand, Rear Ad­mi­ral A.K. Verma (Retd), CMD of GRSE and var­i­ous other dig­ni­taries were also present dur­ing the com­mis­sion­ing cer­e­mony.

Mea­sur­ing 110 me­tres in length, 14 me­tres in breadth and dis­plac­ing 3,500 tonnes, the ship can achieve speed of 25 Knots. The ship is fit­ted with anti-sub­ma­rine rock­ets and tor­pe­does, medium and close-in weapon sys­tems and in­dige­nous surveil­lance radar Revathi. The ship is also ca­pa­ble of car­ry­ing an in­te­gral ASW he­li­copter. Kamorta also boasts of other “firsts” such as a fold­able hangar Door and a Rail­less he­li­copter Travers­ing Sys­tem, which will give he­li­copter op­er­a­tions from the corvette a sig­nif­i­cant edge over other war­ships.

Jait­ley said in the last three months, both the prime Min­is­ter and he had been as­so­ci­ated with many an ac­cre­tions made into the In­dian Navy namely, INS Vikra­ma­ditya, INS Kolkata and INS Kamorta. But this one was spe­cial be­cause of the high in­dige­nous con­tent. he said, at the mo­ment, 42 war­ships are un­der con­struc­tion in var­i­ous

De­fence Min­is­ter Arun Jait­ley, who com­mis­sioned INS Kamorta, de­scribed the de­vel­op­ment as ‘the com­ing of age of our ship­build­ing in­dus­try’

ship­yards of the coun­try which is a wel­come sign of the health of the ship­build­ing in­dus­try. He ex­pressed con­fi­dence that the mea­sures taken by the gov­ern­ment will in­fuse healthy com­pet­i­tive spirit be­tween the pub­lic and pri­vate ship­yards.

En­hanced stealth fea­tures have been achieved by ÔXÕ form of hull, full beam su­per­struc­ture, in­clined ship sides and use of In­frared Sig­na­ture Sup­pres­sion sys­tem for cool­ing the En­gine and Gen­er­a­tor ex­hausts. The ship has a ÔCom­bi­na­tion of Diesel and DieselÕpropul­sion sys­tem with two Diesel En­gines along with one gear­box on each shaft. The common raft mounted gear­box and Diesel En­gines give the ves­sel very low ra­di­ated un­der­wa­ter noise. This is well com­ple­mented with an ef­fi­cient pro­peller which has high cav­i­ta­tions in­cep­tion speed. The de­sign also in­cor­po­rates ac­tive shaft ground­ing sys­tem and multi-zone Im­pressed Cur­rent Ca­thodic pro­tec­tion for sup­pres­sion of Ex­tremely Low Fre­quency Elec­tro­mag­netic sig­na­ture. The very low un­der wa­ter acous­tic sig­na­ture makes it a Ôsi­lent killer on the prowlÕ.

INS Kamorta has a mul­ti­tude of sys­tems such as To­tal At­mo­spheric Con­trol, In­te­grated plat­form Man­age­ment, In­te­grated Bridge, Bat­tle Dam­age Con­trol and per­son­nel Lo­ca­tor Sys­tem. This pro­vides a con­tem­po­rary and process ori­ented Sys­tem of Sys­tems for op­ti­mal func­tion­ing of the war­ship. The ship has a com­ple­ment of about 15 of­fi­cers and 180 sailors. The ac­com­mo­da­tion and liv­ing spa­ces have been de­signed with spe­cial em­pha­sis on er­gonomics and hab­it­abil­ity.
