NEW DELHI—India has yet again scrapped its efforts to acquire 197 light reconnaissance and surveillance helicopters (RSH) for its army and air force, shattering the hopes of Airbus Helicopters and Russia’s Kamov. Airbus Helicopters’ AS 350 Fennec and Kamov’s 226 Sergei successfully completed their field trials in December 2010. Officials from the teams were unavailable for comment.
