I thought we had the capability to manufacture waterjets ourselves?

Our most powerful waterjets today (L&T's LT900) can go upto 3.5MW. Kongsberg's most powerful waterjet is 10 times more powerful. Take a look at this: Indian Indigenous Aero Engine Developments

NGMV's propulsion set up (1 GE LM2500 + 2 Pielstick diesels) would provide ~47-50MW in power. There aren't a lot of waterjets in the world that can handle this much power.

The NGMV is a rather unusual ship. Large enough to be called an OPV or a corvette (~1500 tons), yet fast enough to be a big FPV (~35 knots) & enough missiles to be called a light frigate (8 Brahmos, 24 VL-SRSAM & 8 VSHORADs).

IN is trying to re-create the Vidyut class magic, without the Vidyut's original problems. The Vidyut was a smaller ship with limited range, smaller missile capacity, significantly shorter ranged missiles, almost no AD capacity. The NGMV would overcome all of these problems & would probably be assigned to a similar missile as the Vidyut class.

We need at least 16 of such ships, with Gulf getting more and more active we cant keep sending 7500 ton destroyers to fight UAVs.
NGC should be a priority for navy and CCS.
Provided navy installs anti UAS systems, from mini missiles to DEWs, these are the need of the hour.

At $500 million apiece, the NGC is still quite expensive to be built in nos.
Also these vessels are expected to displace 5000 tons, so more akin to a frigate than a corvette.
I would say what we need is a vessel in the 3000-4000 ton displacement category packing similar offensive firepower (8 Brahmos or 16 NASM-MR) but which comes with a price tag of $300 - $400 million apiece, basically a bridge between NGMV and NGC.

Any confirmation they are supposed to be 5000 tons, AFAIK they will be ~3500tons

$500M? No way, it's closer to about $540M per ship. So yeah, the NGC will probably cost roughly the same as P17A. Building 16 instead of 8 spreads the fixed costs further. And you need that size for endurance (range and endurance differ) and the extra space for humanitarian missions.

Inflation & current exchange rate fluctuation with dollars.

P17a contract was signed a decade back in 2015( 21000+19248= ~40000 rupees)



Now its 11-12 years of inflation by 2026-2027.



NGC's contract is supposed to be signed either in this fiscal year or next.
Total cost of ₹36,000 crore in 2026-2027.
~₹4500 crore per unit





P17a per unit cost is between 5500-6000 crore in 2015's money.

That's ₹9,400 – ₹10,250 crore in 2026, per unit.


NGC is about half the cost of p17a, per unit, domestic inflation adjusted.

P17A costs double of that.

NGC is actually a general purpose warship - anything smaller you would end up with a specialised ship with 1 or max 2 core mission, like asw swcs or ngmv

I am lookinf forward to this class of ship to build up numbers in the fleet. We need at least 24

There are two NGMV designs in front of us : one featuring a waterjet and the other a propeller. Now, if we are indeed procuring the waterjet system, it implies that the earlier design—in which the SSM launchers were positioned at the stern—could very well be the final design.1743439165753.png1743438886384.png
