Project 28 corvettes: India to tender for composite technology for superstructure

[ssheppard]

What kind of destroyer and frigates does Indian plan to procur? As for corvettes use to escort carrier group, see my previous posting.

40 warships, new jets on Indian Navy's 'buy' list

You got to be kidding me. Is this nuclear powered corvettes??

What you meant by nuclear powered ??clear it up please

Dude, know the facts straight before saying anything, ill informed posts shows how much u know about building and operations of a navy,....
For ur reference..read below...

Project 28 Corvettes are the Indian Navy's next-generation ASW platform. They are being built at Garden Reach Shipbuilders and Engineers (GRSE), Kolkata. The first corvette is expected to be delivered to the Indian Navy in 2012. All the four corvettes are planned to be handed over to the Indian Navy by the year 2014.[2][3]

Project 28 is the primary project for driving indigenisation and developing the warship construction industry in India.[1] The aim with this project is to stipulate unprecedented standards while providing opportunities to Indian vendors to develop expertise with the technology. The project, driven by the Navy's Directorate of Indigenisation, has been delayed by two years with a cost overrun from the originally estimated INR 28 Billion to INR 70 Billion, primarily to meet this goal.

The order for the first four corvettes was placed in 2003, with construction commencing on August 12, 2005.

[edit] Design

The basic design for Project 28 was specified by the Indian Navy's Directorate of Naval Architecture, with the detailed design by GRSE.[4]. The design includes many stealth features, including reductions in noise and vibration of the vessels.[5]

Displacing around 2500 tons and a length of around 110 metres, these vessels will have a very high percentage of Indian made equipment – either designed indigenuously or built under license through technology transfer agreements.

The DMR 249A hull steel is produced locally by SAIL (Steel Authority of India Limited). The main machinery is raft mounted to reduce acoustic and vibration signatures. Each gear unit and the associated engines will be mounted on a common raft. The vessel will feature automated control and battle damage systems. The Project 28 vessels use diesel engines built by the Kirloskar Group. DCNS supplied the noise-suppressing raft-mounted gearbox for CODAD propulsion. Wartsila India will deliver the low-vibration diesel alternators to power the on-board electronics.[1] Other signature management control features are built in to combat the ship's infrared, radar-cross signature, noise and magnetic outputs. Two independent interconnected switchboards optimize redundancy and reliability.

It was announced on 21 December 2006 that GRSE awarded France's DCNS a contract to provide a comprehensive engineering package of raft mounted Propulsion Power Transmission Systems (PPTS) for the four corvettes. Under the contract, DCNS will deliver four propulsion packages (consisting of eight reduction gear units on cradles and either thrust blocks) to GRSE. The company will also provide support to GRSE for the mechanical integration of the propulsion plant. DCNS is partnering with Walchandnagar Industries Limited, to provide the raft mounts and other components, including thrust blocks and systems auxiliaries. The first propulsion package was delivered in 2008, with the remaining three to follow at the rate of one per year till 2011.[6]

Armament is to include a license-built Otobreda 76 mm Super Rapid gun in a stealth mount and the usual assortment of weapons similar to what is found on the Talwar class frigates and Shivalik class frigates including a Klub-N missile system in vertical launchers, two Larsen & Toubro built derivatives of the RBU-6000 anti-submarine rocket launcher, as well as Larsen & Toubro torpedo launchers. Revati, the naval variant of the DRDO-made Central Acquisition Radar (CAR), is a confirmed sensor aboard the vessel. Hangar and aviation facilities will also be standard features.
---------------------------------
So did u read the armaments carefully?? U shud hv noticed that they are similar to Talwar(4000 tons) or Shivalik class frigates(5000) tons) albeit in small numbers ....Also the displacement is around 2500 tons which is almost similar to Pakistan navys F22 (if you compare armament there is pretty less diff)....So in effect P 28 corvettes whose primary role is submarine hunting are mini-frigates within an aim to escort the air craft carriers(most priced possession of any navy) in only those waters where submarine threat is imminent......

The P8 antisubmarine planes that you want India to buy(infact India has placed orders for 8 already) are only useful against submarines which operate near the shores because of limited range as well as these planes can't operate from AC that India possess...whereas these corvettes would be to operate in deep seas in an escort which will have replenishment tankers......

Now don't start comparing the operations of India Navy to US,Russian,Chinese or any other..coz everyone has his own strength and weaknesses including goals and threats..

All the green color on there make it look like a golf link. Where is the tee and where is the flag.

but if the global hub for warship building can't build decent frigate or destroyer, old out of dated corvette becomes an option on the table again.

Dude, the fact that you aren't copying (read reverse-engineering) one doesn't mean that the concept has become outdated.. I believe that the facts put forward by members in this thread are self-explanatory enough to prove that corvettes aren't yet an obsolete concept in warfare which you are hell bent on proving otherwise..
get some life...
