Corvettes of Indian Navy : News and Discussions

This is quite disappointing. Not using VLSRSAM, no DRDO CIWS, no increase in number of missiles carried due MRSAM.

This has no capability advantage over the Talwar class despite coming a decade after it.
VLSRSAM VLU is underwork. They are trying to reduce weight and create something like C-dome VLS but 4x2. This VLS seems more focused for something like NGMV. Could be fitted on this ship later on I hope 🤞 preferably with a new VLS capable of quad-packing VLSRSAM.

Maybe the unexpectedly high per unit cost of the ship has to do with the use of the new Kirloskar diesel engine. I am just guessing. But propulsion makes up for a major part of any ship's cost & each ship will have 2 of these diesel engines.

I don't get it why are you calling it high? Its a 5000 tons ships which cutting edge sensors includin towed array sonars anti ship misiles + hanger facilites. Its for all intents and purposes as capable in the roles light frigate roles Talwar takes on.

Here is the price of Upgraded Mogami costs $710 million to $806 million USD per ship. We paid $ 650 millions for the last batch 4 Talwars.

It seems like fair price to me.

That costs as much as a new Type 31 frigate.

Type 31's was priced at $300 million under the contract UK signed. But that contract doesn't cover any Mk41 VLS no anti ship missile and price has already overshot due to rework. Its basically just a CODAD hull + a single rotating AESA panel.

Type 31 has no hull mounted sonar or towed array sonar. NSM and MK41 + air defence missiles will have to integrated seperately.

This one is coming with 4 panel AESA MFSTAR, Hull mounted sonar towed array sonar, air defence VLS all the goodies

No hull mounted sonars, no towed array nowith mk41 no air defence and nsm too will be seperately ordered who knows what the final cost would be.
I know, for basic version they paid around $350 mil with every goodie it will the double. Thus the comment.

Sorry, I deleted you from the orignal post I tagged you in and thought your post was good pointer to add to when comparing costs. Mogami + Type 31.

But Yeah It costs as much as Type 31 and seems to be more well rounded as a general purpose ship.

Yeah hope they do. Otherwise both NGMV and NGC will have 8 AShM and 16 SAMs. I understand that NGC also has anti sub capability and bigger SAMs, but its 3x the weight as well.

Even Pakistani Jinnah class will have more SAMs despite being just 2/3rd in weight

IIT-Madras start-up AstraYAN outbids global giants to bag propulsion integration contract for GRSE’s ₹32,000 cr warships

AstraYAN outbid prominent global players — such as Fincantieri, an Italian shipyard; Navatia, a Spanish shipyard; and RENK from Germany — to emerge L1 for Propulsion System Integration

AstraYAN, an IIT-Madras-incubated deep-tech company, has emerged L1 to bag a tender for Propulsion System Integration (PSI) for the five indigenous Next Generation Corvettes — a light armoured warship Garden Reach Shipbuilders & Engineers Ltd (GRSE) will be manufacturing for the Indian Navy at a cost of ₹32,000 crore.

Lt Cdr Raghuveeraje Urs (Rtd), Chief Operating Officer (COO) of AstraYAN Private Ltd, told businessline that his startup has outbid global majors from Italy and Germany to emerge L1 in the contract for integration of advanced Combined Diesel and Gas Turbine–Cross-Connect (CODAG-CC) propulsion arrangement to power the NGCs.

Now, the bid will enter into the price negotiation stage, which would take at least a month before the deal will be closed with the leading defence PSU GRSE to start the work on the PSI, the COO said. AstraYAN, he stressed, is the first Indian company to achieve this rare complex technological feat and with a team of just 15 people.

This propulsion architecture, as per the GRSE, is designed to support the operational requirements of the versatile frontline combat platforms. Designed for a wide spectrum of maritime missions, the NGCs will undertake multi-role operations, including offensive ship-to-ship and ship-to-surface missile attacks, anti-missile defence, anti-submarine warfare, escort duties, maritime interdiction operations (MIO), including Visit, Board, Search and Seizure (VBSS), and local naval defence.

The ancillary contract process stems from the Ministry of Defence (MoD) on Monday signing deals worth ₹53,866.5 crore with GRSE and Goa Shipyard Ltd (GSL) for overall construction of eight NGCs — five by the GRSE and three by GSL. As per the COO, AstraYAN will pitch in to get a contract for similar PSI that the GSL will require for three NGCs it has to build.

Selection process

The selection process, spanning more than a year, began with the participation of five prominent global players — such as Fincantieri, an Italian shipyard; Navatia, a Spanish shipyard; and RENK from Germany, said the naval architect who has served before with the Indian Navy.

The technical evaluation was done by the Indian Navy, the Naval Science & Technological Laboratory (NSTL), a lab of the Defence Research and Development Organisation (DRDO), and the shipyards.

Following technical and commercial evaluation, three companies — Fincanteri, RENK and AstraYAN qualified, with the Chennai-based start-up eventually being declared L1 for the tender.

The corvettes will measure 127 metres in length and 17.6 metres in beam, with a specified deadweight tonnage of 4,950 tonnes. The warships will have an endurance of 14 days at sea without replenishment and a maximum speed of 26 knots.
