The aerospace giant has finalized an agreement potentially worth $131 billion to provide comprehensive support services for the U.S. Air Force’s F-15 fighter aircraft program. Following Monday’s announcement, BA shares gained roughly 1% in early trading, reaching $213.02.
This comprehensive agreement encompasses modernization efforts, retrofit programs, and ongoing maintenance services for F-15 aircraft fleets domestically and internationally. Key foreign partners in the program include Japan, Israel, and Saudi Arabia. Specific aircraft quantities and delivery timelines remain subject to finalization.
Operations will span through August 2037, with the company’s St. Louis manufacturing complex serving as the primary hub. The facility has seen significant expansion in recent years, and the company recently secured a five-year labor contract with unionized machinists at the location.
According to Vertical Research Partners analyst Rob Stallard, who commented Tuesday, “That’s a lot of F-15 support.” He emphasized that the agreement encompasses both maintenance operations and modernization work for the fighter platform.
Originally developed by McDonnell Douglas during the 1970s, the F-15 platform has undergone continuous evolution. The most recent variant, designated F-15EX Eagle II, became operational in 2021. According to the manufacturer, this aircraft boasts superior weapons-carrying capacity compared to any fighter currently in active service.
Defense Segment Shows Signs of Recovery
Boeing’s defense and space operations have faced significant challenges in recent years. Fixed-cost agreements were negatively impacted by inflationary pressures, resulting in a $5.4 billion operating deficit in 2024 and an additional $128 million loss in 2025. The segment hasn’t achieved annual profitability since 2021.
However, recent trends indicate improvement. During the first six months of 2026, the defense and space division generated a $218 million operating profit on revenues totaling $15.1 billion. Company-wide sales for the same period reached nearly $47 billion.
An agreement of this magnitude provides the division with stable, long-term revenue visibility connected to a proven aircraft platform.
BA Stock Performance Remains Volatile
Prior to Tuesday’s session, BA shares were down 3% year-to-date and had declined 7% over the trailing twelve months. The stock peaked above $240 in early August before retreating as crude oil prices surged from approximately $77 to $86 per barrel in recent weeks.
Aviation fuel expenses represent a significant concern for airline operators, potentially impacting aircraft orders and the company’s commercial aviation prospects. Earlier in the year, shares had fallen below $190 in March before rebounding above $240 by May.
The commercial aircraft division continues to be the dominant factor influencing daily share price movements for BA.
This F-15 agreement provides potential coverage for comprehensive fleet support through 2037 and stands as one of the most substantial defense service contracts the company has obtained in recent history.
