How else will they make case for N-IMRH.

Such small numbers its better to license produce MH-60R/S.

The navy is latching on to the work being done for the IA and IAF. So the engine and transmission's gonna be the same, saves a lot of money there, in fact most of the R&D money is there.

Not true, they want same engine as Romeo as oppose to land version which will have French.

Everything this different. It's practically a different helicopter.

Just my 2 cents (quoting you just for context, trying to address everyone)

123 NMRH along with 111 NUH was the original call few years back. While upcoming large number of OPVs, NGMVs, NGCs, Aux vessels , we could say that 111 NUH will be required.

And for LHDs, Destroyers, Frigates, etc 123 NMRH was required.

Now NUH was a replacement of Alouette III class chopper and NMRH a replacement of SeaKing class of helicopters.

Coming first to the NUH , it was supposed to be a replacement of 2 ton light helo with a light helo with 2 engines to be able to operate in sea conditions. Search and Rescue, transport, recce , etc as primary missions along with able to play a supporting role in Anti Surface warfare and if possible Anti Submarine warfare. That meant a helo of say 3.5-4.5 tons. But as things turned out , inplace of NUH we will likely be investing in ALH variant in class of 5.5 ton. Still that should work. But with a bigger and heavier helo, cost will increase and the numbers will come down.


Coming to NMRH , the requirements were a replacement of 12+ ton class helo in two configs. First the AShW/ASW capability for replacing the MK42B and Ka28PL and second Troop transport as primary role and surface warfare as secondary to replace the MK42C/UH3 helicopters. Now as things turned out, nations didn't exactly replace the SeaKing with a 12 ton ASW capability helo. They went for two types. Generally a lighter 9-10 ton class ASW multirole chopper(like MH60/NH90) and a second 12+ ton chopper to operate from say Amphibious ships (like EC725, AW101,S92).

So it was ultimately inevitable that our 123 requirement would have been broken down into 2 different kinds of helicopters.

Some time back too while discussing in the WhatsApp/telegram group we thought that approx 50+ choppers of MH60R and a similar number of choppers in 12+ ton were ultimately going to be procured.

Now with the N-IMRH program giving a number like 60, it seems that the procurement will be just enough to get 2 squadrons of dedicated Special Ops variant of the helo to operate from shores and another 41 to maybe Operate from the LHDs. Given that Mistrals can carry a mix of upto 20 helos (8 heavier and 12 medium weight helos), 41 seems fine.

And with around 30 or so ships in frigate/destroyer class till 2030 , a minimum of say 3 dozen MH60R along with Naval Dhruvs which we may procure should be enough.

But again, just my 2 cents.

HAL is developing the helicopter with 2 engines as option in order to control the cost of the engine. The other option is the one on Romeo. But all the helicopters will have a common engine in the end, which could be either. Russia is also offering an engine.

But yeah, the naval helicopter will be a different design. But that's fine, the airframe doesn't increase costs much. It's barely anything compared to the cost of the entire helicopter.
