New Delhi Forges Ahead With New Naval Fighter, AMCA: US Media

posted in: Indian Defense 0

India’s Aeronautical Development Agency (ADA) has provided additional details about the planned Twin Engine Deck-Based Fighter (TEDBF), as it moves forward with the Advanced Medium Combat Aircraft (AMCA).

The TEDBF will be developed to replace the Indian navy’s RAC MiG-29K ‘Fulcrum’ fighters, and will differ radically from the AMCA being developed for the nation’s air force.

Optimised for carrier operations, the TEDBF will feature a conventional delta wing configuration with canards and a horizontal tail, whereas AMCA has a twin-tail layout with an emphasis on stealth.

The TEDBF will operate from the navy’s short take-off but assisted recovery carriers INS Vikramaditya and IAC 1: Indigenous Aircraft Carrier 1, which will start sea trials this year and be named INS Vikrant.

Outfitted with folding wings for deck handling and storage, the TEDBF will have a maximum take-off weight of 26t and be powered by two GE Aviation F414 INS6 engines.

The navy fighter will forgo an internal weapons bay. Instead it will have wingtip rails, six under-wing hardpoints, two fuselage hardpoints, and one centreline pylon.

Figures provided by ADA at the recent Aero India show in Bangalore state that the TEDBF will attain Mach 1.6, as compared to M1.8 for the AMCA. The navy fighter will also be smaller, with a total length of 16.2m (53ft in), as compared to 18m for the AMCA.

The AMCA, for its part, is expected to roll out in 2023-2024, with first flight slated a year later. The program received a formal go-ahead in December 2018 and the preliminary design review is almost complete. Airbus Defence & Space is providing design assistance.

The single-seat, medium-weight air force fighter design is optimised for stealth, with its radar cross section reduced through airframe design, diverterless air intakes with serpentine ducts, stealth shaping, stealth materials, body conformal antennae and an internal weapons bay.

“Stealth shaping has been done, with an enormous amount of work on the serpentine intake for the last 7-8 years on all these aspects and they have been mastered,” says an ADA official close to the program.

“We have a big stealth program in the country and the stealth materials for AMCA have already been frozen.”

The air force wants a 24,700lb (110kN)-class engine for the twin-engine AMCA, but initial prototypes will fly with a proven 20,000lb-class engine. The more powerful engine is slated for installation from the fourth prototype onwards. GE, Eurojet and Rolls-Royce have offered solutions for the AMCA powerplant via the government-to-government route.

The AMCA program commenced in October 2010, when feasibility studies for a fifth-generation air force fighter were initiated. The air force issued the Draft Preliminary Services Qualitative Requirement for AMCA in September 2014.
