April 28, 2009 Boeing's P-8A Poseidon anti-submarine and long-range surveillance aircraft has completed its first flight. In the latest development milestone for the plane scheduled to replace the P-3 Orion, the T-1 test aircraft completed a series of systems checks during three hours and 31 minutes in the skies above Seattle on April 25.

Along with a series of on the ground checks, airborne testing of engines, autopilot flight modes and auxiliary power units where undertaken during the flight which reached a maximum altitude of 25,000 feet. The operational aircraft will have a 41,000 ft ceiling and a range of 1,200 nmi.

A derivative of the 737-800 (with the wings of a 737-900), the P-8A will is far from the civilian aircraft it resembles, combining anti-submarine and anti-surface warfare capabilities with a formidable airborne intelligence, surveillance, and reconnaissance platform.

The first five P-8As are currently being assembled by Boeing and major sub-contractors such as CFM International, Northrop Grumman, Raytheon, Spirit AeroSystems and GE Aviation. Formal flight testing is slated for the third quarter of this year.
