Kolkata-class and Visakhapatnam-class Destroyers: News & Discussions

The aesthetics are definitely improving over iterations. Compared to the Kolkata-class, Project 15B has a more streamlined bridge and mast design, better integration of the helicopter hangar, and a slightly longer hull that improves the proportions. The step up in visual and functional aesthetics can be seen better from certain angles. The Russian Navy's influence is still there but has decreased over time. @South block 👍 good stuff. IG or X?
 
Do you think budget constraints led IN navy to try and put all it could in a single ship ? 🤔

Or is it a different doctrine altogether
To be fair, the P-15B class is internally almost the same as the P-15 Delhi class, originally designed in the 1980s. The machinery spaces, propulsion shaft lines, smoke funnels are all identical, only the exterior hull has been given an angled profile. So there's only so much you can do with regard to weapon and sensor placement.

Also, the IN follows the Russian philosophy of fitting HWT launchers amidships unlike LWT used on Western combatants.

The P-15 has clearly maxed out its upgrade potential. Looks like the IN is now shifting focus to the far more modern P-17 design for future programs.

We need a RIM-116 RAM type Missile System for every Indian Warship.... One more layer between VL-SRSAM & CIWS.

The DRDO VShorads seems to be designed for ship-based point defence. AFAIK, no other manpads has reaction control thrusters (rcs) for rapid maneuvers or dual pulse propulsion is such a small airframe. Weight-wise, it still compares well with RAM but has a shorter range. Hope we use a better launcher than the 2x2 round pedestal-mounted launcher shown by Adani. The design inspiration should ideally be the RAM launcher.

Drdo vshoard is designed against subsonic targets.
Rim-116 is designed to engaged both subsonic and supersonic sea skimmers.

Mate, I'm no expert but it seems IN prefers incremental upgrades. Whether it leaves us a 1/4 or 1/3 behind leading Navies is debatable as stealth in naval warfare is an ambigious term. For sure we need more destroyers and submarines though. It's a pity that Trump f**ked up ties so bad when those P8I's are critical tech to deal with PLAN for us.
 
Because its still beneficial.
Subsonic targets are not slow moving drones or helis.
They can very well he subsonic cruise missiles or low flying fighter jets.
Is the weight penalty and added complexity worth it though? VShorads reportedly has a speed of M1.6 which is good enough to take out supersonic targets, imo.

Not an apples to apples comparison but the Barak 1 (vMax ~mach 2) has intercepted Brahmos in tests conducted by the IN.

Yes it is.
The speed and maneuverability is worth it, because its not just designed to intercept ingressing high subsonic speed targets but also egressing ones too.
( Barak 1, barak 8 etc are designed to intercept incoming/ingressing targets mainly)
And don't know if I'm wrong but i think it was barak 8 demonstrating interception of supersonic sea skimming target, not barak 1


For example, rolling airframe missile is a ~70kg missile with ~10kg warhead and ~10km range with faster acceleration and top speeds of mach2+
Barak 1 is actually quite similar to this missile, except being ~26% heavier and twice the warhead weight.


Drdo vshorad is a 20kg missile with 2 kg warhead

Bro, it is called a point defence system for a reason.

Barak-1 was specifically acquired to counter supersonic ASCM around the time of the Kargil war. Iirc, it was in response to PLAN buying Moskit missiles + Sovremmeny DDG from Russia in the late 1990s-early 2000s. During trials B1 was tested against both Kh-35 and Brahmos-1 w/inert warheads.

Granted, vshorad is not in the same class as the latest RAM variant. But I don't see the point of rcs+ dual pulse propulsion on a missile as small as vshorads, unless intended to deal with high speed threats at point blank range. We'll know more in time, I guess.

The Navy should test VSHORAD against a low flying supersonic aerial threat. It can put its effectiveness to rest once and for all. As per what has been incorporated in it, the test should be successful. The 'can' or 'should' will be put to rest. However, theoretically, the missile is capable of taking out a supersonic aerial object. The miniaturised rcs, integrated avionics, and the dual pulse setup should allow it to proceed with such an engagement.

The launcher design needs to be worked upon.

INS Imphal mission deployed in the Arabian Sea participated in PASSEX with USS Gridley of @USNavy @USPacificFleet . The exercises included tactical manoeuvres, cross deck flying, anti-piracy VBSS training and sharing of best practices and procedures towards enhancing interoperability. Both units proceeded with scheduled deployments on completion of the exercise.
 
They should have moved the RBU-6000 to the back where 16 MRSAM are present. What is the point of having just 16 vls in that much space?
Possibly from the center of gravity / stabilisation pov given a ship has to account for roll & high sea thereby CG in some case can shift a little which is covered by a larger area to balance, from a safety point?
