^ Lot of it is fantasy not worth the time discussing, heck first set of P-17a would not be inducted till 2028 to be inducted. Snowballs chance in hell P-18s work would start by then.

John

Originally P-17 was not envisioned to be 6000 ton vessel the original vessel was having displacement of around 4500 tons. But size and weight grew due to changes to superstructure to reduce rcs. There was some discussion (or at least from Russia) for a tie up with Russia on their next Gen DDG but la...

John

Correct. Two helicopters per ship is a mirage given our numbers and acquisition programs.

Yes but I was thinking of Helo UAV + mh-60 would be the way to go. Former would provide round the clock surveillance (replacing ka-31) and latter could be deployed on specific missions.

John

Not sure I follow you Akash Ramjet design (dates back to Sa-6) is bit dated it cannot be throttled and has fairly limited burn time. Russians switched to solid propellant for Sa-11/17 due to that and same goes for Akash NG. We've been over this before. The burn time is exactly per its specification...

John

^ Yes RBU have reload mechanism below deck and takes up more space than a Barak-8 vls module. SR SAM that navy procures will possibly be fitted in P-15a/b (replacing the two AK-630) but I don't see that happening with P-17a (lack of space).

John

Barak-8 have network centric capability so a barak-8 can be fired by one vessel and use mid course guidance from other vessels. Also Barak-8 system costs around 200 million each so guessing adding 32 more will raise cost substantially.

John

Karan M - So we can probably assume that akash has a no escape zone of 25 kms because of its extremely good propulsion system. Not sure I follow you Akash Ramjet design (dates back to Sa-6) is bit dated it cannot be throttled and has fairly limited burn time. Russians switched to solid propellant f...

I was told that the P15s carry one HAL Chetak (SAR duties) and one Sea King Mk42B (ASW duties). I have been inside the helo hangar of INS Delhi. I believe it can certainly house a pair of Sea Kings if need be. Waiting with bated breath for the MH-60R. Got clearance earlier this year from the US Gov...

John

:eek: why does p17A nilgiri image only showing 1 helicopter hanger and and not two like in shivalik class Wiki Chacha says P-17A can house two HAL Dhruv or two Sea King Mk42Bs. So one big helo door, but the helo cabin will house two helos. Better design. Has our P-15 or P-17 vessels ever embarked t...

John

Any particular reason the QRSAM wouldn't fit the Navy bill? Curious to know what's the difference between QRSAM and VL-Astra. Naval operations might mean interfacing with a new radar, very low altitude intercept for sea-skimmers, accommodating sea-clutter. But is there anything in the QRSAM design ...

John

Only Spyder-MR, Derby with booster has height ceiling of around 14 km. Pls find out the height ceiling of Spyder-SR. Of these two, pls find out which one participated in Indian Army SR-SAM tender. Obviously you will know the answer. Not sure the point of sarcastic comment while completing ignoring ...

John

Infact Army wanted a less capable missile than Akash as it wanted the missile system to be light weight. Akash can reach 18 kms in altitude compared to just 6 kms for QRSAM, just 1/3rd. Obviously missile becomes light and more mobile. Kanson where are you getting this 6 km altitude from? That's far...

John

Any Chance, P-15's will get a few Brahmos replacing the Uran missiles, although given some of the Pakistani "Corvettes" built by Damen etc, we should have some cheap missiles to sink many of them without wasting Brahmos. I believe there was proposal to replace it with 2x4 brahmos in incli...

OT let's move that discussion to Intl Aviation we can discuss there.

John

stupid question - if Aakash SAM can do the work do we need the Iron Dome or the S400? rather, why are we going for them when Aakash has the same capability? Akash is a 30km ranged missile meant for targets which leak past the AF's Combat Air Patrols or (now) longer ranged SAMs. The longer ranged SA...

Prasad wrote:It is a ramjet powered missile. Nothing fancy. You could turn the Akash into one and call it Pinaka 3 in a few years' time.

No Akash Ramjet has limited burn time nor can it be throttled, it cannot have range of more than 30 km. Brahmos is different story.

John

Even the baseline Akash SAM has demonstrated counter-PGM capability having successfully intercepted SPICE 2000 glide bombs during acceptance trials as revealed by @DRDO_India. DRDO says that it can intercept targets at altitudes as low as 30 metres. https://twitter.com/SJha1618/status/1171285263059...

GRSE had promised cutting P17A construction to commissioning time from 7-8 yrs during P17 to 4-5 yrs by using modular building techniques. It’s taken them 2 yrs to launch, similar to P17, seems unlikely they would be able to meet their deadline. Although, we can’t just blame shipbuilding time - it ...

John

However, dont forget the altitude limitation. The QRSAM can handle targets flying at 6km, not more.

Source for this that seems to be big limitations. Even OSA have ceiling of 12km.

John

Wasn’t Pars acquisition held up because of Russian complaints.

John

Start with larger orders of a single class of vessel instead of piddly 3-ships each. Avoid pie-in-the-sky procurement attempts like SSK's with Brahmos VLS which hamstrung the P-75I acquisition for years. More ASW corvettes and helos are also the need of the hour. The best way to counter Chinese aer...

I have asked many times this questions--- post the fire in INS Shivalik --- have we seen it back in action? We had numerous exercises and photo-ops post that incident - but sister ships of same class was present but not Shivalik itself... Union Defence Minister Rajnath Singh visits frontline stealt...

Infact Maitri program involves tech transfer of Mica missile as reported. France demonstrated land based Mica (naval) first to Indian audience.

I thought SR SAM will be entirely new missile and the main transfer of tech will be the vertical launch mechanism.

John

In the Aug. 8 incident, Russian scientists were reportedly testing the Burevestnik missile system, which is also known as the 9M730 or, in NATO, as the SSC-X-9 Skyfall. Looks like it was triggered during sea recovery operation one of vessels involved exploded. " US intel report says mysterious...

It is listed as SA-6 replacement as well in some news briefs along with OSA.

Actually, there has been some "discussion" as to why the Aussies chose the French design. Their long term plan is to build nuclear-powered submarines and someone " thought" it s as might be well to have a design that is actually derived from a nuclear boat. Seen that argument I ...

John

kit, if the French sold the Aussies the Shortfin Barracuda...the French will sell India the Longfin Barracuda. That ironclad agreement that the French and Aussies have is for the Shortfin Barracuda platform that is customized for the Royal Australian Navy. The French are however free to sell the Ba...

Note: Asking India to break license agreements and "be like China" constitutes trolling. If you need to ask why, and make repetitive, pointless arguments despite umpteen discussions on the topic which have already addressed these points and reiterated that it is the GOI's stated position ...

Karthik S wrote:Is max diving depth highly confidential ?

I don’t think max depth is 75 meters though it will lower than depth of subs using HY Steel and also more venerable to explosions. I suspect that depth figure is the operating depth in Baltic Sea which is around 70 meters.

John

If the IN insists that the 75-Is must carry B'Mos, its going to be tough for the non- Ru boats. B'Mos NG hasn't arrived yet but will definitely appear before the first boat is built.What the IN needs to avoid is trying like OZ to fit into a conventional boat the capabilities of an N-boat. There are...

Amur is a one-off design meant to reduce weight and was originally intended for littoral duties , in the Baltics for example.What is being offered to India is a flexible design based upon the Amur which comes in several sizes.India can tailor it to its requirements. Nevertheless, it has yet to adop...

The cut down in #s for S-400 IMO is due to high cost Russians were demanding well over 10 billion if I recall correctly. Even then they are fleecing us If you look at breakdown of missiles China got much better bargain than us (of course apologists will claim it has nuclear deal, inflation etc).

John

The Soryu is considerably bigger, than the HDW 209 or Scorpene. Only the Shortfin Barracuda is bigger than the Scorpene. The Soryu would be an excellent boat for the IN. But it will likely never happen. The Shortfin Barracuda is the next best bet. But that will likely not happen either. Project 75I...

Vivek K wrote:Make your own submarines with the expertise generated!

Unlike U-209 where HDW handed over most tech to build the sub locally, DCN has been careful on the tech transfer to make sure MDL will be reliant and cannot simply reverse engineer critical components.

John

Even in case of Brahmos though India has the majority stake, Russians has not allowed or given the clearance to sell to other countries. They cleared it for a few nations but nothing matelerized because Russians offered Yakhont at a much cheaper price to Indonesia and Vietnam. They also packaged it...

It's one thing to sell weapons other thingto fully transfer tech to China under the table and help china with multiple programs.

Rbu-6000 can be used against surface vessels the Rgb-60 rounds can be programmed with a timer for that purpose and I believe we are developing some indigenous rounds to replace rgb-60. Currently an enhanced longer range version has been developed, perhaps we should add other types of rounds more spe...

How fast do you think SSNs prowl when they are hunting? Subs are ambush predators of the deeps. Yes, but Diesel Electric subs are far slower and if go faster it will eat into endurance. Many AIP systems are noisy when run at speed and in order to extend range the subs using AIP move at 1 or 2 knots...

A SSN is in the range of 2-3 billion per unit! You get 4-6 SSK for that money! Which SSK? Kilos perhaps but high maintenance costs and technology wise they are multiple generations behind the Scorpene (even agosta has a better combat management system than the Kilo). Unless you build fully indigeno...
