The US Department of Defense has awarded Boeing a $38.7-million contract to provide mission software updates for the Republic of Korea’s P-8A Poseidon maritime patrol and reconnaissance aircraft fleet.
The initiative covers the development and installation of an updated Tactical Open Mission Software (TOMS) package, building on a broader 2021 ordering agreement that supports aircraft systems and sustainment.
According to the Pentagon notice, the upgrade introduces TOMS version 105K, designed to improve system performance and address parts shortages affecting older components.
It also adds new operational capabilities, including Multi-Static Active Coherent processing to improve submarine detection and tracking.
The software will also integrate the Harpoon II missile, enabling enhanced anti-ship and land-attack options for the aircraft.
Boeing’s TOMS features an open systems architecture for easier updates and integration of new technologies, supporting long-term modernization of the fleet.
Work will take place primarily in Seattle, with additional activities in California, Missouri, Maryland, and Pohang in South Korea.
The project is scheduled for completion by January 2029, with progress to be coordinated with the US Naval Air Systems Command in Patuxent River.
Recent Defense Aircraft Projects
Boeing’s work on Seoul’s Poseidons follows a $2.4-billion initiative that requested the company facilitate rapid prototyping for the US Air Force’s troubled E-7A Wedgetail program.
In February, the company was tasked with a separate effort to upgrade the infrared countermeasure solutions of C-17 Globemaster III airlifters in service with the Canadian and Australian governments.
That same month, Boeing signed a contract valued at more than $100 million to replenish guided munitions for the US Air Force’s B-2 Spirit stealth bombers, restoring the military’s inventory following the Pentagon’s strikes on Iranian nuclear facilities in mid-2025.
The firm also secured another South Korean deal worth up to $2.8 billion last month to modernize the East Asian country’s F-15K Slam Eagle fleet, which was modeled after the American F-15E Strike Eagle fighter jets.
