Fifth P-8A Poseidon aircraft deliver by Boeing to U.S. Navy SEATTLE, Nov. 6 (UPI) -- The fifth of 24 low-rate production P-8A Poseidon aircraft has been delivered by Boeing to the U.S. Navy. The P-8A, based on the 737-800 commercial aircraft, is for anti-submarine warfare and shipping interdiction missions and for electronic intelligence. "This is our final P-8A delivery of the year; we'll ramp up to 12 deliveries, including P-8I aircraft for India, in 2013," said Chuck Dabundo, Boeing vice president and P-8 program manager. Our in-line production approach, which draws on processes developed on the company's commercial and military programs, has been key to our ability to increase production rates while reducing costs. The P-8 will replace the Navy's P-3 maritime surveillance aircraft. The first production P-8s are being flown at the U.S. Naval Air Station Jacksonville, Fla. A fleet of 117 P-8s is planned by the Navy. Boeing said that under low-rate production contracts it is also providing aircrew and maintenance training for the Navy, as well as logistics support, spares, support equipment and tools.
