The Navy plans to purchase 117 of the Boeing Next-Generation 737-based P-8A anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance aircraft to replace its P-3 fleet. The first Boeing P-8A Poseidon production aircraft completed its first flight on July 7, taking off from Renton Field and landing three hours later at Boeing Field in Seattle. The P-8A is the first of six low-rate initial production (LRIP) aircraft Boeing is building for the U.S. Navy as part of a $1.6 billion contract awarded in January. The successful flight marked LRIP-1's completion of final assembly in the company's Renton factory and transition to mission system installation and checkout in Seattle. Boeing will deliver LRIP-1 to the Navy next year in preparation for initial operational capability, which is planned for 2013.
