Anyone have any good details or things they can share on the next corvette project (Project 28A)?


Next Generation Corvette / Project 28A​

Under the Maritime Capabilities Perspective Plan 2022 (MCPP-2022) of 2008, indigenous construction component, the Navy would acquire two Cadet Training Ships, five more offshore patrol vessels (OPV) to add to the four already ordered from Goa Shipyard Ltd, three LPDs, seven Project 17A FFGs, six SSKs under Project 75(I), eight guided-missile corvettes under Project 28A (to add to the four Project 28 ASW vessels being built by Garden Reach Shipbuilding & Engineering), eight GRP-hulled MCMVs, and another integrated aircraft carrier.

By late 2013 a total 8 were said to be on order out of which 4 were under construction. Work on India's first completely indigenous next generation missile corvette, Project 28A, was said as of mid-2013 to be "underway" and the first boat which was undergoing sea trials was expected to be inducted by the end of 2013, after much delay. In the event, it seemed that the initial batch of four was all that materialized, and plans for further units awaited another day.

By January 2016 the Defense Acquisition Counsel was set to move the proposal for acquiring 6 new warships, most likely to be missile capable corvettes. Although there was no information on the specifications the navy had demanded, the first reports were that the proposed ships should have a low radar signature and solid air defenses along with Anti-ship capability. The navy also specified that it would prefer shipyards with capability of building ships of this size to build these six ships.

In October 2016 the Indian Navy began preparation to build seven 'Next Generation Corvettes' at Indian shipyards that would be capable of offensive surface to surface missile attacks, and anti-submarine warfare operations. According to specifications provided by the Indian Navy, the ship will have a range of not less than 4,000 nm, and will be capable of sailing at 27 knots. The India Navy requires all seven corvettes from 2023. The 120 meter long single hull corvettes, or small warships, will have low radar, acoustic, magnetic, visual and infra-red signatures. "The ship should carry a minimum of 8 surface-to-surface missiles and should be able to engage sea skimming missiles, flying 3-5 m above sea level, up to maximum speed of Mach 3. Active towed array sonar, two light weight torpedo launcher should be fitted to the corvettes," according to the Navy's document.

The Indian Navy specified that there should be one multi-function surveillance and threat alert radar in the warships for early warning and target identification. There were presently more than 50 ships and submarines under construction in India. India has already built four anti-submarine warfare corvettes under Project-28, the first of which was handed over to the Indian Navy in 2014. This was built by Garden Reach Shipbuilders & Engineers Ltd with 90 percent indigenization. Next Generation Corvettes� are capable of Offensive SSM Attack, Anti Submarine Warfare Operations, Local Naval Defence, MIO and VBSS Operations. The details are specified in the Operational/Technical Requirements. Seven NGCs are required to be delivered commencing 2023.

Follow up Kamorta and NGMV same? NGMVs are said to have 2000-2500 tons displacement and with 8 anti ship/surface missiles(Brahmos?).

For now they are seperate projects, with NGMV in lower tonnage class like you say and NGC being kamorta tonnage class.

NGMV:


You can see the tradeoff w.r.t endurance and range etc compared to Kamorta and 28A.

===========================

There is however a good argument to combine both programs into one (and select the larger tonnage out of the two):


I also lean towards this sentiment for the reasons given there (mainly one of endurace at sea). It would be ideal to rationalise everything to P-28A and get extra ships in that sized class.

Then go smaller for more patrol boats/OPVs + emerging UUV tech etc to build a robust numbers/hulls based security paradigm in a more optimised way for that (handling peacetime security etc)..assigned to coastguard etc rather than have overlap in kora class size corvette in (ageing) flex-role kind of concept here...given advent of better autonomous vehicle sensoring and sensoring networks themselves compared to before....where more hull numbers are required....i.e broaden here (low tonnage) and bulk up there (larger tonnage).

The Indian Navy’s Kora-class guided missile corvette INS Kora (P61) has fired an anti-ship missile (AShM) in the Bay of Bengal.

The missile hit the intended target, which was located at maximum range, with precise accuracy, an Indian Navy spokesperson announced on Twitter. A video of the launch was also released.

The firing was carried out as part of a drill to demonstrate combat preparedness.



The spokesperson said in a tweet: “#AShM fired by #IndianNavy’s Guided Missile Corvette #INSKora hits the target at max range with precise accuracy in #BayofBengal.

“Target ship severely damaged and in flames.”


The latest firing follows the successful launch of an AShM in the Arabian Sea from Chamak-class missile boat INS Prabal (K93) last week.

As per a tweet by the Indian Navy, the missile hit and sunk the target ship with accuracy at maximum range.

Constructed at Garden Reach Shipbuilders and Engineers (GRSE), Kora-class guided missile corvette were outfitted at Mazagon Dock Limited (MDL).


There are four ships in the class and they primarily serve as surface combatants.

16 of these are planned, they succeed the Abhay-class:


The ASW-SWC (Anti-Submarine Warfare Shallow Water Craft) corvette is an anti-submarine warfare vessel ordered for the Indian Navy from Cochin Shipyard (CSL) and Garden Reach Shipbuilders & Engineers (GRSE). Cochin Shipyard Limited (CSL), signed the contract for the construction and supply of eight Anti-Submarine Warfare Shallow Water Crafts (ASWSWCs) for the Indian Navy on April 30, 2019.

According to the Global Security website, the ASW-SWC is a 750-ton vessel able to reach a top speed of 25 knots and will have a crew of 57 people including 7 officers. She will have a length of 70 meters (230 ft), a beam of 10.2 meters (33 ft), and a draught of 2.7 meters (8.9 ft).

The ASW-SWC corvette will be armed with torpedoes and rockets to conduct search and attack unit (SAU) missions and coordinated anti-submarine warfare operations with naval aircraft. In addition, the vessels shall have the capability to interdict and destroy subsurface targets in coastal waters. These can also be deployed for search and rescue by day and night in coastal areas. In their secondary role, these will be capable to prosecute intruding aircraft and lay mines in the sea bed.

The ASW-SWC corvette will be equipped with highly advanced state-of-the-art integrated platform management systems including propulsion machinery, auxiliary machinery, power generation and distribution machinery and damage control machinery, etc. The design and construction of these ships at GRSE is another significant milestone in the ‘Make In India’ Initiative of the Government of India.

Looks like Soviet Parchim class millenium version

GSL design is straight up piracy of Russia's Pr 22160 corvette. Did they collaborate or something??

while CSL design has too many CIWS for a ship that size

Yes correct abaout GSL-russia collab (not piracy lol). This one will be a larger variant of 22160.

As for the CIWS thing,

From: http://www.spsnavalforces.com/story/?id=386

The close in weapon system (CIWS) should be with radar and EO guided to double up as LIMO weapon. The placement of CIWS should be such that it provides near 360-degree AMD protection without requirement of course alteration.

i.e it will be more multi-role (anti-ship +anti-land + LIMO) rather than dedicated role corvette (like kamorta for ASW).

So I guess a bit more CIWS (with LIMO dbl up in mind) and commensurate reduction on other roles.

The tonnage looks like it will be in 2000-2500 range compared to project 22160 at 1300-1700 tons.

So if the 22160 variant (GSL) is picked, it will be bigger variant of it most likely.

What does @Anmdt think?

GSL design looks more "neat" and solid GRSE design, to be honest cramped up with weapons of different origins. I don't usually like Russian way of handling ship design. They spend too much effort on a certain thing to improve a thing, but at the another place they leave a thing which cancels their earlier effort.

GRSE design, is straighforward conventional design that works everytime.

CSL design, to be honest, my eyes have ached while looking though. If it is selected,there should be another reasons apart from the design.

Among of these,i think only GSL can make it up to 35 knots.

I will wait and see how CSL is going to make 35 knots with that design.

While these 16 vessels are referred to as 'craft' rather than corvettes as they are pretty small (700-900 tons), I think this is a good thread to put this in.

16 Shallow-Water Anti-Submarine Warfare Craft (SW-ASWC) vessels of 2 different designs will be built by CSL & GRSE (8 each), CSL seems to be building all of their order themselves whereas GRSE has offloaded 5 of them to L&T on a sub-contract. The intended roles of these vessels are fairly simple: sanitize the littoral waters in the vicinity of major naval bases on the Eastern & Western seaboards of the Indian peninsula (Mumbai, Karwar, Vizag etc.) and keep them clear of hostile submarines or X-craft that may decide to snoop on vessels coming & going from port.

These will be particularly important for maintaining a strict subsurface cordon around INS Varsha (where the underground pens for India's present & future SSBNs are coming up).

GRSE design:

asw.JPG


CSL design:

CSL ASW-SWC.png


As evident from the images, the craft lack any helo deck (considering operating ranges will be quite limited), while armament includes multiple torpedo tubes (looks like at least 2 x 2, could be 4 x 2) and a n IRL-2 ASW rocket system (license-built RBU-6000) for use against subsurface targets while surface weaponry is understandably limited - with only a single 30mm turreted cannon and probably crew-served 7.62mm MGs.

Can't csl modify that crap design , remove that bridge and frontal vls for brahmos , and add a 8*2 set of vlsrsam on it , vlsrsam already have a 8cell launcher config , it can easily be packed in it , rest that background helipad can be changed to integrate with body ,and whole deck can be levelled .

And mast look poor too ,csl design is worst of worst

Indian shipbuilder Cochin Shipyard started fabrication on two new « Anti-Submarine Warfare Shallow Water Crafts ». The ASWSWC are intended for the Indian Navy.​

Martin Manaranche 03 Dec 2021

The steel cutting ceremony was carried out by Commodore V Ganapthy, Warship Production Superintendent of the Indian Navy. These are the 4th and 5th in a series of 8 vessels.

GRSE already proceeded to a steel cutting ceremony earlier this year – on July 14, 2021 for two other ASWSWC ships.

Anti-Submarine Warfare Shallow Water Craft ASWSWC


For the record, an RFP was issued by the Indian Navy to Defence Public Sector Undertakings (DPSU) shipyards and Indian Private Shipyards in April 2014. Later, contracts for sixteen Anti Submarine Warfare Shallow Water Craft ships have been signed in 2019 with Cochin shipyard and GRSE, charged to build eight ships each with a delivery rate of two ships per year. The future ships will replace the Abhay-class corvettes in service since the 1980s with the Indian Navy.

According to a GRSE statement, the ASWSWCs will have a displacement of 750 tons, a maximum speed of 25 knots and will complement a crew of 57. The vessels will be capable of “full scale sub surface surveillance of coastal waters, SAU and Coordinated ASW operations with aircraft. In addition, the vessels shall have the capability to interdict/destroy sub surface targets in coastal waters”. They will also be capable to perform search and rescue operations, as well as aircraft monitoring and minelaying.
