What Does the $2.8B F-15K Upgrade Contract Cover?
Under the hybrid cost-plus-fixed-fee and fixed-price incentive award, Boeing will design and develop an integrated suite of aircraft systems for South Korea’s F-15K fleet, the Department of War said Friday. Work will be performed in St. Louis, Missouri, until Dec. 31, 2037.
The sole-source contract includes $540 million in foreign military sales funding obligated at the time of award. The Air Force Life Cycle Management Center at Wright-Patterson Air Force Base in Ohio serves as the contracting activity.
What Is the F-15K Slam Eagle Fighter Jet?
The F-15K is a multi-role fighter aircraft that Boeing manufactures exclusively for the ROKAF. It is a variant of the F-15E Strike Eagle fighter capable of carrying out long-range precision strike missions in all weather conditions, whether day or night.
In November 2024, the Department of State approved South Korea’s $6.2 billion F-15K upgrade and logistics support package. The sale included advanced mission system computers, AN/APG-82(v)1 active electronically scanned array radars, electronic warfare suites, and missile warning systems. Boeing was also among the companies named as contractors for the FMS.
Boeing is also supporting similar F-15 modernization efforts for another United States ally in Asia, Japan. The company received a $450.5 million contract from the U.S. Air Force in December 2024 for F-15 command and control capabilities to the Japan Air Self-Defense Force.
