Project 28 ASW Corvette Detailed



At the 11th Defence Services Asia exhibition (DSA 2008) that was held in the Malaysian capital city of Kuala Lumpur from April 21 to 24 this year, Kolkata-based Garden Reach Shipbuilding & Engineering Ltd (GRSE) showcased a representative scale model of the Project 28 ASW corvette. GRSE will in the coming weeks finalise (in concert with Navy HQ) various contract packages for the corvette that call for the design and supply of the vessel’s combat management system, integrated platform management system, battle damage control system, and the weapons suite. But what has already been decided upon is the installation on board of the IAI/RAFAEL-supplied Barak-1 anti-missile defence system, OTOBreda’s 76/62 main gun, Larsen & Toubro-built twin triple-tube torpedo launchers, and the DRDO-developed Revati 3-D S-band radar that will be built by BEL. Presently, sea trials of these two systems are underway on board the Leander-class frigate INS Dunagiri, which has been modified to act as a trials vessel. The frigate’s main mast now carries the 2.5-tonne Revati radar. The main mast also houses an EL/M-2221 STGR fire-control radar illuminator for the Barak-1, as well as a BEL-built Shikari (THALES’ Flycatcher) fire-director of the main gun. The sea trials in this configuration are meant to ensure that EMI emissions do not neutralise each other. The first four planned Project 28 ASW corvettes, each costing Rs7 billion, will also have on board the ELBIT Systems-built Deseaver decoy dispensers on board. The first such corvettes will be launched by GRSE in the middle of next year. The subsequent ‘hunter-killer’ corvettes will be delivered within a gap of 15 months. Though the order for the first four corvettes was given as early as 2003 for some unforeseen reasons plate-cutting for the first vessel commenced only on August 12, 2005. Each corvette will have 2,500 tonnes standard displacement, and a length of 110 metres. It will sail at a maximum speed of 32 Knots. The vessel will be powered by four SEMT-Pielstick 12 PA6 STC diesel engines, each rated at 4,270kW. The hull-mounted sonar will be the BEL-built HUMSA-NG, that will be encased within a fibre-glass dome supplied by ATLAS Elektronik.--Prasun K. Sengupta

prasun,

it's a ASW Corvette not anti air,u have mentioned only about radars and barak missile

but what about sonars what kind of sonars it will have,WHICH TAS and other sonars will b incorporated

if those 8 VLS r for klub missiles on talwar class ,isn't it better to have 16 missiles in missile launchers like
brahmaputra class

what is OTOBreda’s 75/62 main gun

To Anon@9.53AM: The last two lines of the story mentions the HMS installation. The ATAS has yet to be selected from bidders that include BEL, L-3 Ocean Systems, EDO Corp, THALES & Atlas Elektronik.

To Anon@9.58AM: The VLS installations are concealed inside the hull and therefore contribute to stealth features, unlike the 16 Uran-E ASCMs mounted externally.

I implore you to check your facts before you write all manner of contradictory stuff. Where do you see the 2221 on the P-28 model or on the Dunagiri?

Are you sure max speed is 32 kts?

U r also sure about the sonar dome?

Why do u persist in presenting fiction as fact thereby hurting your credibility?

Do you still maintain that the P-28 is a Russian designed corvette derived from the Steregushiy class? My friend, why don't you share some of what you are smoking with the rest of us?

To Beas F137: You seem to be pretty cocksure that you and the likes of you are always right and others are not. If you had even a little bit of common sense you would have realised by now that if I could take photos of the scale-model of the Project 28 ASW corvette (which by the way is only a representative model and not a definitive one), then surely you should have concluded that I ALSO had a decent and detailed conversation with those officials from GRSE and the IN's Naval Design Bureau who would have filled me in on ALL the necessary details. But what you haven't seen as yet is the CAD of the definitive design of the Project 28ASW corvette, which I do have with me (as as I have of the Project 15A DDG and IAC) and which I will upload in due course. Therefore, I would sincerely suggest that you stop--with immediate effect--second-guessing me and questioning my articles. Conversely, if you are so damn cocksure that ATLAS Elektronik is not supplying the fibre-glass sonar dome, then prove it by getting an authoritative quote from any other agency/company/shipbuilder that will not only refute me, but also reveal who the supplier (Indian or foreign) will be. And also get a similar quote from the Naval Design Bureau officially refuting any collaboration with Russian naval design bureaux, because the IN Naval Design Bureau has already, in official interviews given over the past two years to FORCE magazine, detailed all the tie-ups it has had with such foreign naval design bureaux and naval architecture consultants. Therefore, please do not heap all your ignorance upon my shoulders just because you don't have the necessary academic/intellectual/information resources at your disposal in order for you to reach an information and enlightened conclusion.

Also, do check up wioth L & T and ask it who is its industrial partner (and from which country) that will supply the fibre-glass sonar domes in semi knocked-down condition. Similar domes for the Project 15A DDGs and Project 17 FFGs are coming from the UK--something I had written about in FORCE two years ago. You therefore have a long way to go and a lot of catching up to do. Niether the Internet nor Wikipedia will give you such inputs. You have to have 'boots on the ground' and start attending defence expos and talk to informed industry officials to get such info, something which is clearly beyond your means.

THANKS FOR ADHERING TO MY REQUEST AND PUBLISHING THIS APPRECIATE IT

sir if it is powered by those engines why does it have sails?????

BeasF137 said...

Prasun, I see that you have deleted my post. Seems you can't handle the truth. Be that as it may, do tell when you plan on posting the 'definitive' CGI of the ASWC if only to clear up the issue of the vessel's sensor fit?

Sails are not of the ship. They are from photograph behind that ship..
