WASHINGTON (Sputnik) — The two companies announced on Wednesday they decided not to submit a proposal for the T-X Trainer program.
"Northrop Grumman and its principal teammate BAE Systems have carefully examined the US Air Force’s T-X Trainer requirements and acquisition strategy as stated in the final request for proposals issued on Dec. 30, 2016," the statement said.
Leonardo, parent company of the now-defunct Alenia Aermacchi, announced last week that it would no longer jointly pursue the T-X contract with US weapons manufacturer Raytheon.
However Lockheed Martin and Boeing, working with the Swedish company Saab, are both still in the race to provide the training aircraft to replace the current US Air Force fleet of 50-year-old Northrop Grumman T-38 trainers.
