Citat:The biggest challenge involves the development of Radar Absorbent Material (RAM).
He alluded to New Delhi’s challenges in the area of radar cross section (RCS) reduction in comments about the collapse of the 2012 deal to buy 126 Dassault Rafale fighters.
There were several issues that caused the Rafale deal to collapse, he says, but he specifically pointed to France’s unwillingness to part with a proprietary RAM that is applied to the Rafale’s canopy. Had the deal moved forward, Rafales completed in India would have been sent to France to receive the coating.
Other low-observable features in the AMCA will be S-shaped engine intake ducts, which help hide the engine from enemy radars, and canted twin tails.
For what ADA calls “stealth mode,” AMCA will carry a mix of four munitions, either bombs or missiles, in an internal bay. For “non-stealth mode” the jet will have fuselage hard points, as well as three additional hardpoints on each wing. The two inboard hardpoints will be able to carry external fuel tanks.
The engine has not been determined, but is likely to be either the General Electric F414, which powers the Boeing F/A-18 E/F Super Hornet, or the Eurojet EJ200, which powers the Eurofighter Typhoon.
