    A sister ship may indeed become a reality. Although IDRW's "sources" need to be treated with more suspicion than an anonymous black bag in a railway station.

    According to other sources, Navy could consider Rafale-M for this carrier at the earliest.

    EMALS alone will force India to go for Nuclear Propulsion for INS Vishal: Naval Source

    A second Vikrant makes sense, but it shouldn't eat into the budget of more pressing needs like the IAF squadrons or the new Mountain Strike Corps.

    If the navy decides to sacrifice one or two ships for the sake of a second Vikrant, then why not, but the carrier will still need its own air complement and that will increase costs.

    Btw, it seems the Vikrant's flight deck has been cleaned up. Image taken last month.

    It appears they don't want to lose the building experience & work skills acquired in making Vikrant at any cost. That is a valid reason.

    If they give CSL engineers a leave after Vikrant sea-trials are complete, they will have much re-learning to do once Vishal comes up for construction some time after 2020. An interesting variable to watch in such a case will be : how much time they take to build a 2nd ship of the Vikrant-class.

    As long as it doesn't turn into: We got the second ship but we don't have money to buy aircraft.

    Presumably a Vikrant sister ship would be STOBAR as well. So would they go for more MiG-29, or experiment with using Rafale M in STOBAR mode?

    IN doesn't want more Mig-29s. If they want a second Vikrant, then it has to be either the Rafale-M or the F-35B/C.

    15 LCA’s and 15 Mig-29s will soon arm under-construction Carrier INS Vikrant

    India’s indigenous HAL Tejas Light Combat Aircraft (LCA) will serve aboard the nuclear powered supercarrier, INS Vishal (currently under development), but will first see active service on the INS Vikrant now being fitted out and due to join the Indian Navy in December 2018.

    The naval version of Tejas is the only fixed wing combat aircraft confirmed as part of both carriers’ combat air groups. Its key role will likely be as an attack aircraft launching precision guided missiles and bombs at enemy warships or ground targets.

    Two Tejas naval prototypes successfully conducted test flights at the “Shore Based Test Facility” (a full-scale model of an aircraft carrier deck) in Goa.

    The Ministry of Defense recently approved the acquisition of 40 Tejas’ for the IN and 83 for the Indian Air Force.

    Tejas is a single-seat, single-jet engine, multi-role light fighter designed by HAL’s Aeronautical Development Agency for the IAF and the IN. Stealth features have been designed into Tejas, which can carry up to 4,000 kg of bombs and missiles and is armed with one GSh-23 twin-barreled autocannon.

    The air group on the INS Vishal will consist of up to 55 aircraft: 35 fixed-wing combat aircraft and 20 helicopters. The fixed wings will be launched using a catapult assisted take-off but arrested recovery (CATOBAR) aircraft launch system with the new electromagnetic aircraft launch system (EMALS) technology.

    The technology is from U.S. defense contractor, General Atomics, which also produces the MQ-9 Reaper unmanned combat aerial vehicle (UCAV) and is producing a version of an electromagnetic railgun for the U.S. Navy.

    The role of aerial superiority fighter for the INS Vishal is up for grabs but what is certain is it won’t include the Mikoyan MiG-29K multirole fighter to be deployed aboard the INS Vikrant.

    Leading contenders for this key role on the INS Vishal include France’s Dassault Rafale, a naval version of which (the Dassault Rafale M) already serves aboard the French aircraft carrier, Charles de Gaulle, as part of French Naval Aviation (Aéronavale).

    The Indian Cabinet last September approved a deal to buy 36 Rafale fourth-generation, multirole jets from Dassault Aviation as part of the air force’s ongoing force modernization program. IAF Rafales will be able to carry nuclear bombs.

    The Rafales give India a weapon potent enough to deal with Pakistan’s U.S.-made General Dynamics F-16 air superiority fighter jets and the PAC JF-17 Thunder multi-role fighters produced jointly by Pakistan and China.

    The United States’ fifth generation stealth fighter, the Lockheed Martin’s F-35c Lightning II and the combat proven McDonnell Douglas F/A 18 Hornet that serves aboard all of the U.S. navy’s 10 Nimitz-class supercarriers are also in contention for the role of air superiority fighter aboard the INS Vishal.

    The INS Vikrant will carry 15 MiG-29Ks and 15 Tejas’. There will also be 10 rotary wings aboard this carrier, including the Kamov Ka-31 airborne early warning and control helicopters; the indigenous HAL Dhruv utility helicopter and the British-built Westland WS-61 Sea King transport utility helicopters.

    Utter crap, almost every detail is inaccurate but I'll tackle the most obvious; a carrier entering service in 2018 isn't going to have an airwing made up of fighters that won't be in service before 2025 (N-LCA).

    New super aircraft cannot land or recover aircraft for four days without failing and fixing this would require a redesign

    According to a June 28 memo, Michael Gilmore, the Defense Department's director of operational test and evaluation, said the most expensive warship in history [the new Gerald Ford aircraft carrier] continues to struggle launching and recovering aircraft, moving onboard munitions, conducting air traffic control and with ship self-defense.

    "These four systems affect major areas of flight operations," Gilmore wrote in his report to Pentagon and Navy weapons buyers Frank Kendall and Sean Stackley. "Unless these issues are resolved ... they will significantly limit CVN-78's ability to conduct combat operations.

    Fixing these problems would likely require redesigning the carrier's aircraft launch and recovery systems, according to Gilmore, a process that could result in another delay for a ship that was expected to join the fleet in September 2014.

    Commanders said delays to the USS Gerald R. Ford have resulted in extended deployments for the operational carriers in order for the Navy to meet its commitments around the world, placing additional stress on sailors and crew members.

    The report comes just days after the Navy announced the Ford will not be delivered before November 2016 due to unspecified testing issues, walking back testimony from April in which Stackley told Congress the Ford would be ready by September.

    Now that delivery date could be pushed to 2017, according to the Navy.

    To date, construction on the Ford is 98 percent complete with 88 percent of the test program finished.

    Despite delays to the USS Gerald R. Ford's delivery, the Navy says that the Ford-class carriers will yield a $4 billion reduction per ship cost as compared to its predecessor, the Nimitz Class.

    The next carrier in the Ford class, the USS John F. Kennedy (CVN 79), is scheduled to launch in 2020. That ship was 18% percent complete as of March.

    Arresting Gear

    The Navy estimates the arresting gear could be operated for approximately 25 consecutive landings, or cycles, between critical failures. That means it has a “negligible probability of completing” a 4-day surge “without an operational mission failure,” Gilmore wrote.

    The electro-magnetic launch system’s reliability is higher but “nonetheless I have concerns,” Gilmore wrote. Recent Navy data indicates the carrier can conduct only 400 launches between critical failures, “well below the requirement” of 4,166 takeoffs, Gilmore wrote.

    Gilmore said the system would have to increase its reliability to 1,600 launches between critical failures “to have a 90 percent chance of completing a day of sustained operations.” The Navy program office’s determined that the carrier “has less than a 7 percent chance of completing the four-day combat surge” plan, Gilmore wrote.

    The current MK 7 hydraulic arresting system outfitted on the ten Nimitz-class aircraft carriers will be replaced on the Gerald Ford-class carriers by the Advanced Arresting Gear (AAG) unit for recovery operations. The AAG is designed for a broader range of aircraft, including UAVs, while reducing manpower and maintenance. Rotary engines which use simple energy-absorbing water turbines (or twisters) coupled to a large induction motor provide finer control of the arresting forces.

    Existing water twister systems are fixed in their capacity to absorb energy. For AAG there is a variable energy dissipation by the water twister. There is an actual moving plate inside the water twister that adjusts how much resistance to the water is generated. Initially there was an underestimation of the forces involved inside the water twister because it is a three-dimensional flow field. Internal plates that take the force of the water weren't strong enough and finding a solution has taken some time

    In 2016 the Office of the Inspector General, U.S. Department of Defense found that the AAG remained unproven.

    I also voiced concerns about it.
