The US Department of Defense has contracted Boeing with a $38.7 million deal to deliver mission software upgrades for South Korea’s P-8A Poseidon maritime patrol aircraft.
The effort involves developing and installing the latest Tactical Open Mission Software (TOMS) package, building on a 2021 framework agreement focused on system support and sustainment. The new TOMS 105K version is intended to enhance performance while resolving supply issues linked to older components.
The upgrade introduces advanced features such as Multi-Static Active Coherent processing for improved anti-submarine warfare, along with integration of the Harpoon II missile to expand strike capabilities against maritime and land targets.
With its open architecture design, TOMS enables easier updates and future technology integration, supporting long-term modernization. Work will be conducted primarily in Seattle, with additional activities across California, Missouri, Maryland, and Pohang, and is scheduled for completion by January 2029 under coordination with Naval Air Systems Command.
This contract follows a series of Boeing defense programs, including a $2.4 billion initiative supporting the US Air Force’s E-7A Wedgetail development. The company has also worked on upgrading infrared countermeasures for C-17 aircraft used by Canada and Australia.
In addition, Boeing secured a contract exceeding $100 million to replenish munitions for B-2 Spirit bombers after 2025 operations, and recently won a deal valued at up to $2.8 billion to upgrade South Korea’s F-15K Slam Eagle fleet, based on the F-15E platform.
