Boeing Wins Contract to Modernize Nine P-8A Poseidon Aircraft for US and Australia

On November 4, Boeing awarded Boeing a $119.7 million contract modification to advance the modernization of nine P-8A Poseidon maritime patrol aircraft, according to [zona-militar.com].

Seven of the jets belong to the U.S. Navy, while two are operated by the Royal Australian Air Force, as reported by [hispaviacion.es]. The agreement, as part of a list of agreements reached by the U.S. Department of War, also contemplates the provision of Type A update kits belonging to Block 2 of Increment 3 and the installation of four kits already acquired on US Navy aircraft.

The agreement relies on a fixed-fee incentive structure to supply Block 2 Increment 3 Type A modification kits. [zona-militar.com] said that Washington will contribute $110.1 million from its fiscal year 2027 aircraft procurement funds. Meanwhile, Canberra covers the remaining balance through established bilateral cooperation mechanisms, bringing Australia’s share to $9.5 million according to [hispaviacion.es].

Boeing improves P-8A fleet ISR&T capabilities

The Increment 3 Block 2 package represents the most advanced upgrade designed for the P-8A fleet. “It improves the Maritime Intelligence, Surveillance, Reconnaissance and Targeting (ISR&T) capabilities of Naval Aviation, the eyes of the Fleet,” said Michael Wosje, as reported by [zona-militar.com].

Naval Air Systems Command in Patuxent River, Maryland, oversees the contracting activity. Boeing will perform the modification work across three U.S. facilities: Jacksonville, Florida handles 79.6% of the tasks, St. Louis, Missouri takes 10.9%, and Mesa, Arizona accounts for 9.5%.

Boeing completes technical work by May 2030

The contract requires Boeing to complete all technical work by May 2030. The update introduces a new radomo, updated antennas, improved sensors, and a modified wiring harness.

Technical work will also be developed in a coordinated manner in Oklahoma City, San Antonio, and the Hamamatsu air base in Japanese territory, extending its validity until mid-November 2027 under the supervision of the Air Force Life Cycle Management Center in Massachusetts, through the Foreign Military Sales program.
