Boeing gave a 2h 31min flight debut to the Indian navy's first P-8I maritime patrol and anti-submarine warfare aircraft on 28 September, with the 737-based type due to be handed over in 2013.

Carrying the registration IN320, the aircraft took off from Renton Field, Washington, and underwent a series of airborne systems checks before touching down at Boeing Field in Seattle. The company will begin installing its mission system equipment "in the coming weeks".

Boeing said its test pilots performed accelerations and decelerations of the 737's CFM International CFM56-7 engines and checked its autopilot flight modes during the first flight, which also included taking the aircraft to an altitude of 41,000ft (12,500m).

"Flying the first P-8 for an international customer is a key milestone for our entire team," said Boeing P-8I programme manager Leland Wight. "We have transitioned to P-8I production, and remain on track to deliver the first aircraft to the Indian navy in 2013."

"We are looking forward to this potent platform joining the Indian navy," said Rear Adm D M Sudan, the service's assistant chief of naval staff (air). The navy will receive eight P-8Is as replacements for its Tupolev Tu-142s, and has an option to increase its order by a further four examples.
