Indian Navy Developments & Discussions

Technically, what is the obstacle preventing integrating of missiles of merchant A with radar of merchant B?

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

Ir camera to measure ir signature

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?

 

[Ayan Barat]

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.

Is there a reason we still use the Soviet doctrine?

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.

INS Vagsheer s Delayed Commissioning Highlights Indian Navy s Submarine Woes

Assuming they use the same hull design for P17-B, with so much space they can just replicate the 8x UVLM and 16x SAMs in the "2BHK" space behind the RBU.

Anyway this is their plan for the MLU for this ship, right?



Anyway, accha hai 6 of these beauties are still in the pipeline, unlike the earlier model of building only 3 ships of a class, atleast in numbers we won't be lacking

Indian Patrakar "Do Not Do Dalali of Foreign Maal For Once Atleast" Challenge Level : Impossible

-----------------------------------------------------------------------------------------------------

But all the six boats entered service without their primary weapon system-heavy weight torpedoes (HWTs), after plans to import 98 of these from Italy’s Whitehead Alenia Sistemi Subacquet (WASS) for Rs 1,800 crore was scrapped in 2017.

But in December, seven years after the WASS tender was terminated, the MoD signed a Rs 877-crore contract with Naval Group, to arm all six Scorpene SSK’s with Defence Research and Development Organisation (DRDO)-designed ‘Varunastra’ Electronic HWTs.

However, the MoD did not disclose the price of the torpedoes, manufactured by Bharat Dynamics Limited, in its announcement via the Press Information Bureau (PIB) on December 30, 2024. Industry estimates suggest that each Varunastra torpedo costs between Rs 10-12 crore. Consequently, the total cost for the 98 torpedoes originally ordered by the Indian Navy would be an extra Rs 980-1,176 crore.

Naval Group’s collaboration was essential in this endeavour to assist the Indian Navy and DRDO technicians in customising the submarines’ 533 mm torpedo tubes to Varunastra’s guidance and fire control system and aligning it with the submarines’ SUBTICS combat management system. Fitting the boats with Varunastra that has a range of 40 km and speed of up to 40 knots (74 kmph) onto the submarines necessitates time-consuming hardware adaptations, software integration and extended testing, industry sources said.

Indian Dalali Patrakar also does not know that an additional 3 Scorpene class submarines are going to be ordered, INS Vagsheer is definitely not the last boat of the class.
