The US Department of Defense has awarded Boeing a $38.7 million contract to upgrade mission software for the South Korea’s P-8A Poseidon maritime patrol aircraft fleet.
The contract includes the development and integration of an updated Tactical Open Mission Software (TOMS) package, building on a 2021 agreement covering aircraft systems and sustainment. The upgrade introduces TOMS version 105K, aimed at enhancing performance while addressing component shortages affecting legacy systems.
The modernization also adds new operational capabilities, including Multi-Static Active Coherent processing to improve submarine detection and tracking, along with integration of the Harpoon II missile for expanded anti-ship and land-attack missions.
Boeing’s TOMS uses an open systems architecture, allowing easier upgrades and integration of future technologies to support long-term fleet modernization. Work will be carried out mainly in Seattle, with additional efforts in California, Missouri, Maryland, and Pohang. The project is expected to conclude by January 2029, in coordination with Naval Air Systems Command.
The program follows several recent Boeing defense initiatives, including a $2.4 billion effort supporting rapid prototyping for the US Air Force’s E-7A Wedgetail program. The company has also been tasked with upgrading infrared countermeasure systems for C-17 Globemaster III aircraft operated by Canada and Australia.
Additionally, Boeing secured a contract exceeding $100 million to replenish guided munitions for the US Air Force’s B-2 Spirit bombers following mid-2025 operations, and another deal worth up to $2.8 billion to modernize South Korea’s F-15K Slam Eagle fleet, derived from the F-15E Strike Eagle.
