Navy's Next Destroyer Line Christened Visakhapatnam-class, 1st Launch Next Week

[Srinivas]

I was talking about getting the battle cruisers but many members here think that they are useless.
Look at the fire power these beasts carry as battle cruisers:

20 × P-700 Granit (SS-N-19 Shipwreck) AShM
• 14 × SS-N-14 Silex ASW cruise missiles (Ushakov only)
• 96 S-300F Fort SA-N-6 Grumblesurface-to-air missiles (Ushakov,Lazarev, Nakhimov)[citation needed]
• 48 S-300F Fort and 48 S-300FMFort-M (SA-N-20 Gargoyle) long-range SAM (Pyotr Velikhy)[2]
• 128 9K95 Tor (SA-N-9 Gauntlet)point defense SAM[2]
• 40 OSA-MA (SA-N-4 Gecko) PD SAM
Guns:
• 1 × twin AK-130 130 mm/L70 dual purpose gun (2 × AK-100 100 mm/L60 DP guns in Ushakov)
• 8 ×AK-630 six-barreled Gatling 30 mm/L60 PD guns (Ushakov,Lazarev)
• 6 × CADS-N-1 Kashtan gun/missile system (Nakhimov, Pyotr Velikiy[2])
Torpedoes and others:
• 1 × 10 RBU-1000 305 mm ASW rocket launchers
• 2 × 6 RBU-12000 (Udav-1) 254 mm ASW rocket launchers

• 10 × 533 mm ASW/ASuW torpedo tubes, Type 53torpedo or RPK-2 Viyuga (SS-N-15) ASW missile

Imagine this sort of firepower in one ship. And then multiply them with 10.

Seriously, Navy should look at getting these things to complement our carriers and even be a part of CBGs.

Cruisers add a powerful punch to CBG's.

They are a crucial part. Even if we have one Nuke powered cruiser armed with powerful missiles, it makes a big statement to the countries in times of peace or war.

A single cruiser with its fire power can strike the many targets.

I was hearing about AK 630s will be replaced with some combination of guns CIWS and SR-SAM like on the Delhis but no confirmation anyplace

It may be possible that 48 units of LRSAM may be 32 Barak8 and 16 Nirbhays but only speculations atm

I think that speculation on the final weaponry load-out at this time will be a little premature. Some new weaponry is under consideration/development. take for example the 157 mm Main Gun or the replacement for the AK-630 CIWS. Which are not finalised, though the direction is clear.
Some Gun based CIWS is very probable considering it is the most economic option available apart from being available as a multirole weapon.
Most of all (speculatively speaking) the Nirbhay capability will have to be allowed for though.

I think that considering all this; even DND may not have frozen the design for the Armament suites for the Vizags.

The Project 15B vessel will retain the hull form of Kolkata class destroyers and most of its systems, there will be some significant upgrades. For example, some structural changes in the superstructure will improve stealth and include better sound and infrared suppression. The Project 15B will also differ from the Project 15A through employing a fully flush deck. This will improves stealth because of the smoothness of the overall deck with far fewer angles and corners. The displacement of each Project 15B will be approximately 7,000 tons, a 200 ton addition over the Project 15A Kolkatas.

48 cells for LR-SAM
16 cells for AShMs
2 Kavach chaff dispensers
2 Mareech ATDS dispensers
4 AK630

Refer to page-10. 48 VLS launch cells for SAMs, either all meant for the LR-SAM or 16 of them have been set aside for QR-SAMs. There is another (issued after the above, had posted the link in P-15B thread) which calls for 4 sets of SAM launch modules with 16 cells each (64 in total). Note that the VSR remains the same as that on the P-15A due to the MoD's inability to select an active-VSR.

No, the 48 cells earmarked are specifically meant for SAMs, Mazagon's own tender spells that out explicitly.

You are correct. I am awaiting pics to be relased at best by 20th April to understand further configs. Hope we get some aerial shots closeups to understand better

If the weapons fitment of the ship has not been finalized yet then look ahead for a string of delays as multiple changes will be required at a later date, often alterations like these will require un-doing work already finished.

 

[PARIKRAMA]

BTW do you believe the potency is upped a lot from 15A. i still feel it lacks a lot more punch when compared to say state of art Burke class armaments

Its not like before; the modular construction allows for much more flexibility than in the past. Some modules can be re-designed/ reworked much faster than in the older method of "keel-up construction".
And another thing; not all the developments/decisions are in the public domain. So; why not wait till that happens?

Russia and China working on Nuclear powered destroyers . Why don't we join Russians for the same ? More over I like see some serious development on SSGN development . At east 3/4 of them can work as conventional deterrent . Armed with some 100 nirbay this could be a nice addition for our power projection across the globe. Especially from Andaman Nicobar base.

Why we need to match Bruke class??

One thing, if not 64, but damn sure 48 VLS, 8 BrahMos (AshM) and 8-16 Nirbhay (Land Attack variant) will be power package.

Here is the tender specifying 64 cells for SAMs. http://www.mazagondock.gov.in/newsite2010/pdfs/ots_jully14/Tender Doc 6000000437.pdf

India has the capability to build these cruisers !

Since we use all destroyers under P15A/B from P15 project not much can be done except stealth feature and upgraded armament like hypersonic bramos , LR SAM and Nirbay with 1000 KM cruise missile . With Hypersonic Brahmos our fire power will increase to a new level and I air defence too.

Next step should be focused on Nuclear Cruiser with double the armaments of Hypersonic Brahmos ... mouth watering capabilities

India has the capability to build these cruisers !

Hopefully we will go for it . May be after 2022 or so. But we must to project our power . And is there any possibility for SSGN like the American one . Am so impressed with their destruction force during Lybia war. One SSGN fired some 110 Tomahawk cruise missile resulting in total destruction of Lybian infras.

The next in line SSBN after Arihant class have more fire power. A single SSBN of Americans can hold hostage of an entire medium sized country.
