onli problem is vikrant type AC cant support catapult system and without it we cant oparate owr jets to their full potential

What is Vikrant type?

What is Vikrant type?

the one thats under construction at cochin docks

That's not the only problem the other is without catapult you can operate helos in AWACS role and that limits your range

EMALS = Nuke reactor = money = 2 conventional carriers.

Yup i agree with you about it.. but life time operating cost will be lesser than conventional carriers...

 

[GURU DUTT]

Vikrant could be anything but catapult. That's a given

well maybe they can but wont be fesable on a small ship it need at least 60K tonne type to support it ... said some friend some time ago maybe im wrong on this one

We had a very nice analysis about this in one of the previous threads when we delved into this issue. And overall cost of nuclear-powered was still much higher than that of conventional. Let me see if I can look it up.

Only if you get a platform like v22 osprey. Not any bigger though

you post a link if you can...

but even if we have V22 osprey on IAC as AWACs its still too big maybe we can increase the size of elevators .... lets see

Its not intended to be catapult by design. You can't say Sukhoi 27 type cannot be stealth. Its how they were made.

Now I see. The size is a non-issue. INS Vikrant (1st one) was some 20000 tonne and had catapult. As does Brazil's French carrier Sau Paulo which is 30000 tonne. As is France's French carrier CDG viz 40000 tons.

so as per you say sir it would be very good to have 40-45K class conventional ACs with EMALS in IN i guess IN should think about it serouslli will save a lot of cash

 

[#hydra#]

If you want to put more thn we've to reduce the nos of helis and Awacs

Yeah 20 helicopters is not required for aircraft carrier..

No not EMALS. The other catapult - Steam catapult. 65k ton steam catapult is very good and shouldn't cost through the roof. The key is that we build several copies of it so as to benefit from economies of scale and to ensure that the knowledge isn't lost.

 

[Abingdonboy]

The Indian Navy has written to Lockheed Martin, BAE Systems, DCNS, and Rosoboronexport for proposals on designing a 65,000 tonne aircraft carrier.
The indigenous warship, IAC-2, must carry 30-35 fixed wing warplanes and 20 helicopters. It should be have a top speed of 30 knots and above and more importantly, have a catapult to launch aircraft.

The IN would ask the aforementioned companies for very specific design inputs (ie about positioning of arrestor cables, angle of deck, jet blast deflector mechanisms etc etc) but NOT for an entire off the shelf design- that is the job of the IN's Naval Design Bureau (NDB) who design all of the IN's indigenous warships and have been working on the IAC-2 project for years now.

The NDB has all but frozen the IAC-2's design, all that is waiting is 2 key things- USG clearance of EMALS sale to India and the GoI/MoD's nod for nuclear propulsion.

There is not going to be a huge cost differential between a 40-45,000 ton EMALS-equipped carrier and a 65,000 ton EMALS-equipped carrier.

EMALS itself brings about massive cost savings in the long term as compared to the steam catapults currently in service that are not only expensive and labour intensive to maintain but because of their inherently less-controllable nature (EMALS is inherently controllable) the stresses they put on the a/c they launch is considerable and thus leads to lower life-spans and thus greater costs.

EMALS = Nuke reactor = money = 2 conventional carriers.

Steam catapults are old tech and would incur their own costs (in both man hours and actual dollar terms) in the long run. If you want EMALS you are almost certainly locked into having nuclear propulsion.


Swings and roundabouts....

Of course there is no free lunch. We can only look at cost/benefit of each alternative from our perspective.
