Is there some encrypted code involved that you need to acquire from both merchants to integrate the radars and missile together?

Seen this happen with fighter jets also, and with submarines recently 800cr being paid to Naval Group so that they integrate Kalvari class Sub's systems with the DRDO Takshak torpedo.

Licensing fee with OEM. Technically you can integrate the Barak 8 to an Indian radar but warranty and spare parts supply is affected.

But given how IAI has completely parted ways from this joint ventures Barak-8/LRSAM thingy and made a completely new line by themselves so that they can sell it without any interference by us; I don't think this would be that big of a deal.

Also we're slowly moving away from Israel in terms of whatever we used to procure; Barak-8 is almost on the verge of getting replaced by Kusha, Derby's already pretty much replaced by Astra, same with Python, guidance kit used to be a big chunk of Israeli item but now those are also here, small arms won't be a big deal given all the local firms...don't know what repercussions are we fearing.

GRSE's design for comparison.

The SAM system seems to be the VSHORAD launcher (Igla S or VSHORADS).

Any update when they will deliver the first ASW corvette? Is 4 years needed for the construction of one 1000 ton corvette?

As per the MoD Year-End Review, INS Arnala was to be delivered/has been delivered to the Navy in December 2024 itself.

ASW corvette! Do you mean ASW-SWC whose pic he attached? If yes then first ships of both the subclasses are delivered and currently in trial. If things go well then in a couple of months both would get commissioned.

As for the delay, then it's a norm in shipbuilding everywhere in the world that the first one or two ship of a class generally takes longer to comission. The yards don't have much idea of how things would go. And then in trials, it's a continuous to and fro between the customer and manufacture on how things need improvement, minor tweaks. Take the example of INS Khanderi, the second Kalvari. In trials Navy found some serious 40 or so issues and sent it back. So it's pretty usual

More interesting details like

I mean you can obviously use it for that, but I'd guess it's from the ship's firefighting crew.
Every navy has multiple of these handheld thermal imagers on every single ship and submarine to locate the source of a fire in thick smoke-filled rooms. We most probably use COTS systems but in USN they even have one standard issued called Naval Infrared Thermal Imager or NIFTI.

Anyways, here's something interesting.
The Navy would never tell you this, but you can definitely build two 2BHKs on the bow of the new Nilgiri Class frigate. Imagine what else is the Navy hiding from us...

I was going to comment about all that unused deck space.

Just get rid of those damn rdu, put more vls, put one Astra based RIM analogue on the bow and one at the aft, above the helo deck. Heck there seems to be space to squeeze one more between the radar mast and the exhausts. It's not so hard, we have the core technologies for it, just need to build a RIM type frame.

We're using our RUB-6000 in similar roles as ASROC, albeit with one thirds the range but increased magazine depth.

One of the primary reason why we never bothered about these is that fact that we use the Soviet doctrine of heavy torpedo on surface vessels. Compare ASuW weapons on two premier destroyer
• Arleigh Bruke class
- 324mm torpedo; short ranged, 10km
- VL-ASROC; long ranged, 25km
• Kolkata class
- RBU-6000; short ranged, 8.5km
- 533mm torpedo; long ranged, 50km.

A 50km long ranged torpedo is significant inferior to a VL-ASROC in prosecuting an enemy submarine. The torpedo just takes much longer to get to the target.

Is there a reason we still use the Soviet doctrine?

significant inferior

That's some pretty harsh comment my Guy, I guess even USN doesn't consider them to be "signifincantly inferior"
VL-ASROC > 30km, approximate TOT of 10min to deliver a 50kg warhead
Varunastra > 50km, approximate TOT of 30min to deliver a 250kg warhead

You can either have a fast acting but ship disabling torpedo or a slow but keel breaking torpedo; can't have both so it's up to you.

Primary reason is the fact that Soviet doctrine is cheaper compared to the alternative. What's Western doctrine?
For AShW - You've 70 fighters in every CSG, you've 11 such CSG
For primary air-defence - You've 70 fighters in every CSG, you've 11 such CSG
For ASuW - you've a fleet of whopping 50 hunter-killer submarines and yeah, you guessed it right...70 fighters in every CSG, you've 11 such CSG
Everything else you see on in a Western CSG is more or less just to protect these 70 fighters with secondary duty of long ranged fire using TLAMs.

So for a smaller navy who can't afford multiple full-sized carrier strike groups, the Soviet doctrine is quite decent.

Also the fact that we've used Soviet doctrine for so long is also a reason we continue to use it. But I'm pretty sure that after a decade or so we'd have moved away from Soviet to Western doctrine. Something that China has already achieved.
