The brahmos in any universal cells will be brahmos mini ,which is much smaller.Brahmos 2 may require specialized cells though.
Brahmos-m will be closer to nirbhay.Lets wait and see.

The Scramjet missiles are closer than we think. Between that and the time we may finally have BrahMos-NG (Mini) ready, which will be post-2025, I doubt there will be much of a use for the Mini in IN ship-based duties, at least on the bigger capital warships.

It has tremendous potential in air-launch and submarine-launched applications though.

Yeah,the mini will probably be useful for mounting on smaller frigates/corvettes though.And ofc air launch and sub launch.
 
From 6th May 2019. Launch of INS Vela. Notice the ship in the background, that is a Vishakapatnam class destroyer, most possibly INS Mormugao. Notice the recently constructed radar tower and exhaust structure that is still un-painted.

Here is a satellite picture of the Mormugao from 2018 with no exhaust superstructure.

@vstol Jockey don't you think we should ask these people to build three more of the current line. The new ones will take time. In the meanwhile the docks can crank a few more of these out.

I fully agree with you and want IN go in for six more with AIP. By the time these six with AIP are produced, the first of the present six will come up for mid life upgrade and fitment of AIP.

Sir, Doesn't the banner on P-15B DDG show yard No 12704 and isn't yard no 12704 INS Vishakhapatanam and not Mormugao?

That's a good point there. I don't have much to counter it. Except these :
Pics from the launch ceremony of INS Karanj on 31 January 2018. See that ship in the background. That is most definitely a Vizag class.

Here we have pics from launch of INS Khanderi on 12 January 2017.

In all these pictures you can clearly see the MF-STAR radar housing tower is painted.
Whereas, pictures from the INS Vela launch clearly shows the same tower isn't painted. Assuming, no one scraped the paint off, that's clearly a different ship. Now let's look at stage of construction : INS Vishakapatnam is being built along side INS Mormugao, INS Imphal was recently launched, INS Kohima is waiting to be launched. The only ship other than INS Vishakapatnam that ready to have radar, exhaust superstructure built is INS Mormugao. This is why I guessed it was Mormugao.

As far as I can say about the Yard no conundrum, ships are floating objects once launched and are moved around during various phases of construction. Maybe Vishakapatnam is ready to move to sea, Mormugao will sit where Vishaka was sitting to get radar and other systems mounted and Imphal could sit where Mormugao was sitting to get the superstructures built. It is production line after all. One ship moves out the other comes in.

But all this is just guesswork, I would take them very seriously. Important thing to remember is we haven't had a good look of the INS Vishakapatnam since Jan 2018. The last pics were this : (please ignore the anime)

The current status of the Vishaka can tell us a lot about the status of the other boats as well.

True. I was perplexed at finding Vishaka with its mast in primer like colour, though I agree with your assessment, that the probability of it being Murmagao is greater

That's rust my friend. Not any colour. Look at some of the other photos.
Ships with large superstructures take more time in being built(if you are using telescopic construction method) and are thus left exposed to the environment for longer duration. This allows enough time for the formation of rust on the exposed surface.
 
New surface-to-air missile technology reduces radar signature of Navy fleet

So far, the Medium Range Surface-to-Air Missile has been deployed on three destroyers -- INS Kolkata, Chennai and Kochi. Each of them carries 32 missiles deployed in "vertical launch unit" canisters

New missile will allow large naval formations to operate with a greatly reduced electromagnetic signature

The eponymous Medium Range Surface to Air Missile(MR-SAM), jointly developed by India and Israel to defend the Navy’s warships against incoming anti-ship missiles, achieved a crucial landmark on Friday. MR-SAMs fired simultaneously from different vessels were directed to two different targets by a single warship, allowing a naval flotilla to reduce its give-away electromagnetic signature.

Warships typically switch on their multi-function surveillance and target acquisition radar (MF-STAR) while firing an MR-SAM – usually when an incoming anti-ship missile is still over a hundred kilometres away. The radar guides the missile towards the target, bringing it close enough to allow the missile’s seeker to home onto the anti-ship missile, and strike it precisely while it is still 70 kilometres away.


If a second incoming anti-ship missile is detected, another warship launches a missile to down it. But heavy electronic signatures from multiple radars make the flotilla easily detectable, allowing the enemy to target it with anti-radiation missiles(ARMs).

This vulnerability was reduced through the “cooperative engagement firing” tested on Friday. Two navy destroyers INS Kochi and Chennai fired MR-SAMs simultaneously at two simulated incoming missiles. But then, INS Chennai kept its radar switched off, while INS Kochi directed both missiles to the target through electronic data links.

“The missiles of both ships were controlled by one ship to intercept different aerial targets at extended ranges… The Indian Navy has become a part of a select group of navies that have this niche capability,” stated the defense ministry.

This allows large naval formations – such as an aircraft carrier battle group (CBG), which typically includes a carrier, along with several large warships like destroyers or frigates – to operate with a greatly reduced “electromagnetic signature”.

In a statement of confidence in the MR-SAM, which has been developed by the Defense R&D Organization (DRDO) in cooperation with Israel Aerospace Industries(IAI) and manufactured by Bharat Dynamics Limited (BDL), the defense ministry announced that the missile system would be fitted “on all future major warships of the Indian Navy."

So far, the MR-SAM has been operationally deployed only on three destroyers -- INS Kolkata, Chennai and Kochi. Each of them carries 32 missiles deployed in “vertical launch unit” (VLU) canisters. Now they will be fitted on four more destroyers being built under Project 15B and seven frigates being constructed under Project 17A.

IAI has designed and developed about 80 per cent of the MR-SAM, including the Elta MF-STAR radar. The DRDO has designed the missile’s propulsion system, including a sophisticated dual-pulse motor, thrust vector controls, and the electrical harness (wiring).

It was originally planned to deploy the MR-SAM in Indian as well as in Israeli navy warships. While BDL has received orders from the Indian navy, orders from the Israeli navy are still awaited.

The MF-STAR radar is built in Israel, as are the VLU canisters.

The DRDO says the MR-SAM project has enabled the indigenous development of a number of new technologies that will feed into new projects, such as the “quick reaction SAM (QR-SAM). Besides the dual pulse rocket motor, this includes a new smokeless propellant.

Mazgaon Dock is infested with Muzzies. Far too many fire incidents in this dockyard. It points to delibrate sabotage. We must investigate these incidents more pro-actively.
