Moreover quantity have it's own quality, 15 MMMA will provide much higher coverage than 6 P8i.

Now entire MMMA project will be put on back burner.

We will have 18 P8I total saar

anyway the MPA has a chance because the Vadodara plant guys will need more C-295 orders to keep their jobs

DAC clears 10 capital acquisition proposals worth approx. Rs 1.05 lakh crore under Buy (Indian-IDDM) category​


Defence Acquisition Council, under the chairmanship of Raksha Mantri Shri Rajnath Singh on July 03, 2025, accorded Acceptance of Necessity (AoN) for 10 capital acquisition proposals amounting to approx. Rs 1.05 lakh crore through indigenous sourcing. AoNs were accorded for procurement of Armoured Recovery Vehicles, Electronic Warfare System, Integrated Common Inventory Management System for the Tri-Services and Surface-to-Air Missiles. These procurements will provide higher mobility, effective air defence, better supply chain management and augment the operational preparedness of the Armed Forces.


AoNs were also accorded for procurement of Moored Mines, Mine Counter Measure Vessels, Super Rapid Gun Mount and Submersible Autonomous Vessels. These procurements will enable mitigation of potential risks posed to the Naval and Merchant Vessels. To provide further impetus to indigenous design and development, AoNs were accorded under the Buy (Indian-Indigenously Designed Developed and Manufactured) category.

>Super Rapid Gun Mount

So is this the reason Surat and Udaygiri are using the ye olde round turret for the 76mm SRGM ?

Indeed, individual sensors will more advance as it's a newer aircraft, newer 6 p8i we are planning to buy from 🇺🇸 will also be more advance than older p8is.
But mmma, lacks other sensors navy requires, like MAD.
That's why mmma was not proposed to navy, instead another c295 based more enhanced mrmr was proposed.

Second cruising speed of c295 is ~480km/h
P8i's Cruising is 815km/h, ( 42% faster).

C295 have endurance of 11 hours, with max payload it's 5.5 hours .

Let's assume endurance of 8.5 hours for c295 based mmma/mrmr aircraft.

For open oceans let's assume 1400km away from coastal base from Indian mainland where the mission is.
C295 based mrmr with it's 480km/h speed will take about 3 hours to reach that distance, and 3 hours to come back after mission.
This leaves mission loitering time/ time on station of 2 hour 30 minutes or 2hour 40 minutes

In comparison.
P8i in its current form with all the sensor have 11 hour endurance.
With 815km/h Cruising speed.
It will reach 1400km distance in in 1.7 hours, return journey similar 1.7 hours.
Total 3.4 hours, so remaining time on station is 7.6 hours or 7 hours and 36 minutes.

P8i have 2.85 times more time on station than proposed c295 mmma/mrmr in open oceans.
Almost 3 times more time on station.

Second thing once again, is related to speed.


P8i can reach the mission area at almost half the time will take for a c295 based mmma/mrmr to reach the same mission area.

So for "open" area p8i is a better "platform" given how large indian ocean is.

Though we can buy some mrmr for navy too against pakistan.
mmma is for coastguard.

That’s not a bad thing though, the P8I is overkill for a lot of lower end roles. The C295 being a turboprop will be a lot cheaper to operate, plus will have pretty decent endurance too, much greater that the Dornier/Hindustan-228 and carry more and larger sensors too. The fact that you can add an inflight refuelling probe if needed can really extend its range too, and possibility of a low cost A2A Refueller variant for the Navy to operate is an added bonus. It’s never bad to have a cheap and versatile aircraft in production in your country. Now that it’s here, nothing should stop us from making, experimenting with and inducting newer variants. I personally wouldn’t rule out a C295 based AWACS too for either the IAF or IN at some point. IMO it’s whatever the HS-748 couldn’t be.1751544622900.webp

C295 based mrmr for navy against pakistan is a good idea.

True, same for the smaller airstrips in the Islands too, that cannot handle larger aircraft. A lot of people tend to forget how backward and neglected up until recently our infrastructure is in the Islands. Some airstrips can handle only Do-228 and ATR size aircraft.

Another I would also like to add, while p8i will have 2.5-3 times more time on station.
But during this time it will also fly faster.
P8i on station hunting for subs will fly at 1500-5000 feet, at speeds of 650-700km( they also have other missions where they fly lot slower like deploying sonobouys etc).
While c295 based mmma/mrmr will fly at 1500-5000 at speeds of 300-400km/h.

The combination of these means, a single p8i neptune can cover more than 5 times the area a single c295 based mmma/mrmr will cover, at the same distance(1400km)far away from mainland base.

More than 5 times the area, let that sink in.

Looking at 737 specs, With 800kmph it won't have endurance of 11 hours.
Only massive benefit p8 has is response time, time to cover xyz area during war time. In peacetime C295 will be better option to share the load. It will cover easily 70-80% area that P8 can but will take a little more time.

"The P-8I Poseidon (used by the Indian Navy) and its American counterpart, the P-8A, are both based on the:

🔹 Boeing 737-800ERX (Extended Range) airframe"
It is a military-optimized version of the 737-800, modified specifically for the P-8 Poseidon program.

P8i have endurance with full fuel and it's equipment of more than 10 hours.

P8I is an exceptional platform, theres no other ASW platform that comes close to it. Only thing I'd like to see is the sharing of atleast some data so we could, over time, transition to our sensors and equipment once it exceeds capabilities of export-rated US stuff.

I mean we case also buy the p8i platform aircraft from boeing US and modify it with drdo radars, mad and other sensors like we are doing with awacs,istar etc.
Though will require extra development time + extra cost, plus part of p8i deal Is also sort of "jaziya" to 🇺🇸.

If we are going to design something ground up, better to join the airbus effort on the A321XLR, much more capable base platform than Boeing 737NG.

But developing new stuff will be extremely expensive imo, plus time costs as well.
