Indian Navy Gets US Go-ahead to Deploy EMALS and AAG on its New Supercarrier

I could predict that Indian has to buy the entire CBG in future ,when China begins to mass produce his nuclear-powered aircraft carrier .

There will be huge amount of money in demand , so indian people should work harder and prepare enough cash for the coming shopping.
 
Actually, there are lots of problems with the reactors of French aircraft carrier, which causes the top speed to be only 27 knot.
Those were propeller related. AFAIK, their propellers were getting damaged due to cavitation.

Sure Will Have Money,

First start the MASS PRODUCTION of Nuclear Carrier,
 
they waited
EMALS was in discussion for quite some time now by General Atomics. however this deal(if and when it goes through) won't be a stand alone product. It will incorporate several weapon systems as well and could include E2D AEW platform.
However EMALS is an extremely power hungry system and can operate on an N powered AC properly and therefore the premise that INS Vishal (proposed 65000 t displacement) flat deck AC will see much more US participation than is known.
 
There is no difference between a military and civilian nuclear reactor
From reactor physics point of view, none.
But operationally they are like chalk and cheese.
Power reactors can be refuellled whereas naval reactors can't. these therefore have hugely enriched fuel and the core itself has to be replaced one the power output reduces below a certain value. Now since this is very difficult work, most AC and subs are designed for only one core replacement during their codal life and due to this, the material of construction of core is designed for much higher degree of neutron damage sustenance.

Actually it is interesting, while EMALS is power hungry it is more compact as well compared to steam based solution. India will need to get nuclear reactors right. the best we have are 150 MW. USS Nimitz has two 550 MW reactors.

Did India sign the treaty?
There is no difference between a military and civilian nuclear reactor, used to generate power.
Compaction is the key. First thermo nuclear bomb was actually a 'factory' of sorts. You cannot fit that in bomb bays of a bomber now do you. Same with the reactor. You need compact ones for mobile platforms like carriers. India has a 83 MW reactor for her subs and a 150 MW one for the next generation sub under construction. It will take more than that for a heavy carrier which we are building plus power will be required to keep the EMALS working.
 
Since when Carriers are 'MASS PRODUCED'?

Only during WW2.

The Indian Navy will become the second navy in the world to deploy the advanced Electromagnetic Aircraft Launch System (EMALS) to launch planes from its aircraft carriers and the Advanced Arresting Gear (AAG) to recover these planes after the U.S. Department of Defense recently approved the sale of these sophisticated systems to India.


DoD recently granted General Atomics Electromagnetic Systems (GA-EMS), the California-based developer of EMALS, export approval for both EMALS and AAG to the Indian Navy.

EMALS is designed to replace the steam catapult systems currently used on all 10 of the U.S. Navy's Nimitz-class, nuclear powered aircraft carriers. The newest aircraft carrier, the USS Gerald R. Ford (CVN-78), is the first carrier to deploy EMALS. The Ford is scheduled for deployment in 2019.

EMALS launches carrier-based aircraft from an aircraft catapult using a linear motor drive instead of the conventional steam piston drive.

Its main advantage is it allows for a more graded acceleration, inducing less stress on the aircraft's airframe. It's also lighter than a steam catapult system and cheaper to operate. In addition, EMALS can launch aircraft that are heavier or lighter than those handled by steam catapults.

The Advanced Arresting Gear (AAG) system uses electric motors for aircraft deceleration during aircraft carrier recovery operations.

The Indian Navy's "Indigenous Aircraft Carrier II" (IAC-II) program calls for building 65,000 metric ton supercarriers. The second carrier in the Vikrant-class and India's first supercarrier, the INS Vishal, is in the design phase and will deploy both EMALS and AAG.

The Indian Navy in November 2016 confirmed plans to integrate EMALS catapults into its future supercarriers by revealing the dispatch of Letters of Request (LoR) to the U.S. DoD to buy this advanced aircraft launch system.

It said the LoRs cover the purchase of three EMALS under the U.S. Foreign Military Sales Program. Sources in the Indian Navy told media the LoRs were issued in February 2016.

The navy expects the Pentagon to approve the LoRs and to issue its Letters of Acceptance (LoA) approving the deal within the next few months.

Purchasing 3 catapults, does that mean the new Indian carrier will have that same number? Or will it be 2 or 4?

Well to be honest, I will not believe this unless I see this ship sailing. India has done too many false starts in the past too.
 
The Indian section shall be renamed as Indian procurement section, as they can build nothing. nothing amazing.

Don't forget to fit the mighty Brahmos onto your super hodge podge carrier, cause it's all you have to boast.

Don't worry we will take care what we wanted,
 
Nuclear powered aircraft carrier with EMALS and F-35Cs is the way ahead for IN.

Yeah right. F-35s in IN with Republicans in power.

Might as well call them to colonise India and make Washington DC the capital of India.

Dude, you didn't warn us till now.

We are eagerly waiting.

Come on, warn us. :D

:tup:
indeed and one more advantage is faster launch capacity (or lower idle period between launch of two aircrafts). During war time, this can become a critical operation.
Also launch capacity (in terms of aircraft weight) is higher and this would make it possible to house larger aircrafts (especially the reconnaissance). this will increase potency of AC.

the best we have are 150 MW
USS Nimitz has two 550 MW reactors.
i believe the rating you've mentioned for A4W core (Nimitz class) is Thermal output not the electrical (ie MWt and not MWe). By applying thumb rule for conventional saturated steam cycle turbine, i suppose 550 MWth would translate to around 140-150 MWe, which still is a very large value sufficient to power linear motors of EMALS.
@Penguin Sir, Could you help here regarding typical power requirement comparison for steam catapult and Linear motor systems.

Congratulations on C919 first flight!

You could simply drop 'Sir' its not apt for me.

Indian reactor in Arihant is having 83-86 MW, thermal power, not electrical power.
