Along with production aircraft, the P-8A team also has built and is testing six flight-test and two ground-test aircraft. The flight-test aircraft are based at Naval Air Station Patuxent River, Md., and have completed more than 1,500 flight hours.
A derivative of the Next-Generation 737-800, the Poseidon is built by a Boeing-led industry team that includes CFM International, Northrop Grumman, Raytheon, Spirit AeroSystems, BAE Systems and GE Aviation.
The Navy plans to purchase 117 Boeing 737-based P-8A aircraft to replace its P-3 fleet. Initial operational capability is planned for 2013.
