Is India dropping INS Vishal for INS Virat-II??

Published September 15, 2016 SOURCE: Anand SG / FOR MY TAKE / IDRW.ORG

India’s Current Defence minister Manhohar Parrikar likes to save money and that too in major ways and latest casualty and off from his to-do list, might be the development and construction of India’s Second 65000 tonne Aircraft carrier with Nuclear propulsion. Recent media reports indicate that IAC-2 or INS Vishal is off the priority list of Indian Defence Ministry and Indian Navy is unlikely to get official funding for the project anytime soon due to complex and high development cost enabled with the project after carrying out in depth discussion with American and Russian Industrial partners. The Indian Defence Ministry is now actively considering development of sister Vikrant class conventional indigenous aircraft carrier with added and improved capabilities which might be named INS Virat-II after INS Virat-I which was a British designed Centaur-class aircraft carrier recently decommissioned from the Indian Navy service in keeping with Navy tradition of renaming warships of the same class. Many Defence analysts for long had voiced concern and also had taken a cautious approach on possible development of IAC-2 with Nuclear propulsion due higher developmental and ownership cost involved over a conventional aircraft carrier. India also could have required to carry out considerable amounts of investments in its shipyards to build human and technological expertise to handle repairs on a Nuclear propulsion ship. Ulitmialtey cost seems to be major hurdle which might have forced the Indian Defence Ministry to fall back on conventional aircraft carrier technology to rely on to keep developmental cost low and benefit from prior development of India’s first indigenously developed INS Vikrant-II which is now at the final stages of fitments before it is enters service into Indian Navy by 2018. Will India build another aircraft carrier on the lines of INS Vikrant-II or will decide to develop a 65000 tonne new aircraft carrier with conventional propulsion is the decision which likely will be discussed in coming months closely with all shareholders before final call is taken on the development of the second indigenous aircraft carrier.

I know its not exactly a great source but the prospect of having improved vikrant class carrier thrills me. Always amazing to embrace indigenous weapons.MP is going in the right direction.
@Abingdonboy @PARIKRAMA

Do you have any info about this?

Wrong info. Idrw.rg posting some rumors as facts and articles lately. Vikrant 2 is already on the card but Vishal is too. Navy already issued official procedures to procure EMALs and guardian drones system. . . Shipyard was confident on building 2nd or even 2 more Vikrant class at the same time but Navy rejected the proposal as IAC 1 itself running out of schedule.

Excellent little nugget buried in an Indian Navy briefing today on the P15B destroyer line was this official art of the P17A stealth frigate. The follow-on class to the successful and proven P17/Shivalik-class, the P17A is known to be under build with significantly greater stealth qualities in its superstructures. While there's been some guesswork over the years about precisely how Directorate of Naval Design plans to hone the Shivalik-class for greater stealth (this isn’t the first art out there, there have been a few over the years), this image suggests a cleaner approach with higher inclines and a modular deck configuration.

Livefist’s sources confirm that the P17A borrows stealth sensibilities being infused in the P15B destroyer line, with several areas of commonality in materials, system/housing shaping and deck assembly configuration. The hope is that stealth will be significantly higher in these two classes than their predecessor classes.
Sure, art is art. But if this is the way the Indian Navy is going, it's more proof that its ship design and build capabilities are among the finest in the world.

@Penguin is this i-mast ?

This does look stealthier than FREMM or type 26.

@Penguin is this i-mast ?

This does look stealthier than FREMM or type 26.

Our version is similar to that of Italy 6900 T. France has its own version with 6000 t.

Length wise longer than Italys and 3 mts slimer for even more Stealthier frontal RCS 19 m vs 17.5 m beam.

More SAM in P17A at 32 barak against 16 with FREMM. But less Main armaments with only 8 bramos against 8 × MM-40 Exocet block 3 anti-ship missiles and 16-cell SYLVER A70 VLSfor 16 × SCALP Naval land-attack cruise missiles ... But we have double hanger heli pad against French. But Italys has 2 × SH90 or 1 × SH90 and 1 ×AW101.

Over all cost French 690 million dollars P17A about 600 million to 900 million.(today) May be 1.1 billion with final cost by 2022/23... It's first induction date .

But as far as fire power is concerned we will smoke these frigates with 290 km superior range and speed of bramos. Their inventory is old Otamat or exocet... 180 km at 690 mph against ..2,100 mph with 290 km. ...

But if you come with Type 26 we have lots to catch up with massive beam, similar length. But has 48 Sam and 24 cells for cruise missiles. It's a class apart. It coat around 1.25 billion dollars today. We will catch up with our next generation destroyers... But packing more stuff in a small hull is where technology superiority comes in.

Its a torpedo but using supercavitation system.
In 2004, posci magazine published this pic

the supercavitating torpedo--a rocket-propelled weapon that speeds through the water enveloped in a nearly frictionless air bubble--may render obsolete the old submarine strategy of sly maneuvering and silent running to evade the enemy. The superfast torpedo could be outfitted with conventional explosive warheads, nuclear tips or nothing at all--a 5,000-pound, 230-mph missile could do enough damage on its own.

The hard part about building a rocket-propelled torpedo isn't so much the propulsion as clearing a path through the ocean. Water creates speed-sapping drag; the best way to overcome that drag is to create a bubble that envelops the torpedo--a supercavity. A gas ejected uniformly and with enough force through a cavitator in the nose of the torpedo will provide such a bubble, permitting speeds of more than 200 mph and a range of up to 5 miles (traditional torpedoes have slightly longer ranges, but lumber at only 30 to 40 mph).

Shkval

We dont know its range or tech specs, but looks like we are taking a project for supercavitating torpedos.. Interesting times ahead

Nope.

I-mast 500 with integrated APAR

Actual I-mast 400 for RNthN Holland class OPV and Doorman JSS

You graphics show the ELM 2248 MF-STAR radar as used onboard e.g. INS Kolkata (D63)

We dont know its range or tech specs, but looks like we are taking a project for supercavitating torpedos.. Interesting times ahead

VA-111 Shkval

Effective firing range
Shkval: 7 km (4.3 mi)
Shkval 2: 11–15 km (6.8–9.3 mi)
Weight: 2,700 kg (6,000 lb)
Length 8.2 m (26 ft 11 in)
Diameter 533 mm (21 in)
Launch speed: 50 knots (93 km/h; 58 mph)
Maximum speed: in excess of 200 knots (370 km/h; 230 mph)

Shkval is mainly intended to nuke a carrier strike group

An air launched version in particular could be well suited to combating fast and manoeuvrable sea targets.

 

[GuardianRED]

Is the VA-111 still the only confirmed super cavitating weapon system ? Is this the same system that accidentally took down the kursk?

 

[Penguin]

The Russian Navy's final report on the disaster concluded the explosion was due to the failure of one of Kursk's hydrogen peroxide-fueled Type 65 torpedoes. Hydrogen peroxide is a liquid. The VA-111 is launched from 533 mm torpedo tubes at 50 knots (93 km/h) before its solid-fuel rocket ignites and propels it to speeds of 200 knots (370 km/h). So, in answer: no, this is not the same weapon.

In 2004, German weapons manufacturer Diehl BGT Defence announced their own supercavitating torpedo, Barracuda, now officially named "Superkavitierender Unterwasserlaufkörper" (English: "supercavitating underwater running body"). According to Diehl, it reaches more than 400 kilometres per hour (250 mph). Not sure if that went anywhere.

INS Kochi, an indigenously designed and constructed guided missile Destroyer, was commissioned into the Indian Navy on 30 September 2015. The ship is one of the most potent surface combatants that have been constructed in India. It measures 164 metres in length and approximately 17 metres in width, with a full load displacement of 7500 tonnes. The ship has a propulsion system, comprising four powerful reversible gas turbines that help it to attain speed in excess of 30 knots. The ship's electric power is provided by gas turbine and diesel generators, which together produce 4.5 Mega-Watts of electrical power. The ship has a complement of 40 officers and 350 sailors. INS Kochi derives her name from the vibrant port city of Kochi. This is a tribute to the city’s distinct maritime character and culture, and symbolises the special bond between the Indian Navy and the city of Kochi. The ship’s crest depicts a sword and a shield together with a Snake Boat riding on the blue and white ocean waves, which symbolise the Malabar region’s rich maritime heritage and martial traditions. The crew of the ship abide by the Sanskrit motto “Jahi Shatrun Mahabaho” which means “Oh Lord Almighty! Let me Prevail over the Enemy”.

This is AMAZING.

14 Fighter jets on the Deck along with 4 Helicopters. That is a total of 18 Aircrafts on the deck.

INS Vikramaditya hanger can hold 10 Fighters jets (Mig 29K class) along with 10 more Helicopters.

So the Total maximum capacity of INS Vikramaditya is 18 + 20 = [/B]38 Aircraft's. [/B]
