    If you can give the power requirements of EMALS for F18SH and E2D launches.

    The nuclear propulsion of the CDG had several issues as well, doesn't mean that, that will stop French navy to procure another one. The advantages might outweigh the disadvantages right?

    Actually they are very different!

    French forces belong to NATO, therefor force projection is important for them, while India does not align itself to a defence cooperation and IN aims on coastal defence and sea control around India.
    Also French navy plans with Rafale M as the sole carrier fighter, possibly combined with a naval UCAV. While IN plans with different 4.5th gen fighters and a stealth fighter in future.
    And if I may project a bit, if Brexit goes through and we don't see a nationalistic shift in France, the French interests could be on top of a new EU defence strategy, which gives French forces a leading role, rather than one fighting for it's autonomy.
    While we are struggling to keep even neighbours like the Maldives and Sri Lanka on our side.

    I'm against prestige projects. Building EMALS for one or carriers is just a complete waste of time and money.

    EMALS technology transfer to India has been blocked by Donald Trump unless India signs CISMOA and BECA agreements. So much for India US honeymoon.

    I had in fact spoken about such blackmail to the person directly responsible for IAC-2 and he seemed very clear in his opinion that no such thing will happen. The problem with IAC-2 is that we can't afford a blackmail once keel had been laid. The Carrier will become junk if sanctions are applied or technology denied during the service of the carrier. This shud tell you why I have never supported any kind of weapon purchase from USA. Its better not to have any weapon than to have a US supplied weapon.

    Very true...

    Actually we should go for a modified Sister ship of IAC-1 Vikrant class before moving to Vishal class as that should be enough for our needs till 2035, which can then be modified for helicopter carrier. Simultaneously we should start work on developing Indigenous EMALS as this technology is also useful for RAILGUN and civil use for MAGLEV trains.

    China is at advance stage of developing EMALS and are even claiming it to be superior to US one as US EMALS is based on AC traction whereas Chinese have developed EMALS based on DC traction. We should make it a national mission and develop it on Fast Track basis just like we developed our Missiles and now by 2020 we are aiming to be import free for missiles.

    No problems with nuclear propulsion, problems with the propellers
    Perhaps also the level of protection against radiations was not enough at the time of the first tests, but it was easy to fix.

    http://www.defencenews.in/article/I...EMALS-and-AAG-on-its-New-Super-Carrier-251979

    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.

    there was nothing wrong with the radiation, it the prop design. they used a prop design from its predecessor as an intem as the public at the time thought it was a waste of money. it will be change during a midlife refit, i believe it has already undergone such refit.

    Donald Trump had taken a dislike to EMALS as they are costly compared to steam catapults. Here developing country like India wants the costly one. What a contradiction

    yes its very costly.
    but the tech. is the latest.
    old 1 is like mig 21 era ...........................soooooooo priced at extra low .
    new is like f 22 or say t 50 ....................soooooooo priced at the highest bracket.

    the 1s who want to pay price of mig 21 to buy the latest gears will land up with jf 17 type a/cs.

    mig 29 was the cheapest & rafale was 1 of the costliest ................is the tech or performance or availability the same ?

    so suit yourself.

    Steam catapults work just fine and have huge power where as the digital ones are not reliable. And the cost is prohibitive. gallery-1494526682-gettyimages-450651946.jpg

    i did say its VERY costly.
    my point is that its next gen. tech. soooo ..................
    reliable or not will depend on the researchers to fix all the bugs.

    https://en.wikipedia.org/wiki/Aircraft_catapult

    On 31 July 1912, Theodore Gordon Ellyson became the first person to be launched from a U.S. Navy catapult system. The Navy had been perfecting a compressed-air catapult system and mounted it on the Santee Dock in Annapolis, Maryland. The first attempt nearly killed Lt. Ellyson when the plane left the ramp with its nose pointing upward and it caught a crosswind, pushing the plane into the water. Ellyson was able to escape from the wreckage unhurt. On 12 November 1912, Lt. Ellyson made history as the Navy's first successful catapult launch, from a stationary coal barge. On 5 November 1915, LCDR Henry C. Mustin made the first catapult launch from a ship underway.[3]


    if tomorrow all guns r replaced by lasers then again the new 1s will be VERY costly.

    The Navy launches its first fighter from the radical electromagnetic catapult onboard the $12.9bn aircraft carrier USS Gerald R. Ford


    An F/A-18F Super Hornet fighter jet has been shot into the sky during the first-ever launch and recovery using the U.S. Navy's new electromagnetic catapult system.

    The test happened aboard the USS Gerald R. Ford, the Navy's new $12.9 billion warship, which was commissioned and heavily praised by Donald Trump just a week ago.

    The new technology - called the Electromagnetic Aircraft Launch System, or EMALS - has previously shown it can hurl dead-loads, but this is the first time the catapult-like launcher has propelled an actual aircraft into the air.





    All new technology has teething issues, EMALS are well worth the cost and effort.
