Boeing secured a contract worth up to $131 billion to support the U.S. Air Force’s F-15 fighter jet program, a deal that sent BA stock up about 1% in premarket trading to $213.02 after the announcement.

The contract, announced Monday, covers aircraft production, systems integration, modernization, upgrades, retrofits, sustainment, and maintenance work tied to the F-15 fleet. It includes aircraft operated in the United States as well as by foreign military customers such as Japan, Israel, and Saudi Arabia. The exact number of jets involved and the delivery schedule have yet to be finalized.

Work under the agreement will continue through August 2037 and will be based at Boeing’s St. Louis factory, giving the plant a workload horizon stretching more than a decade. Boeing has expanded its presence there in recent years, and last year the company ratified a five-year agreement with local union machinists.

Vertical Research Partners analyst Rob Stallard said on Tuesday, “That’s a lot of F-15 support,” adding that the deal covers maintenance and upgrades for the aircraft.

The F-15 was first introduced by McDonnell Douglas in the 1970s. The latest variant, the F-15EX Eagle II, entered service in 2021. Boeing says the aircraft carries more weapons payload than any other fighter jet in service.

Boeing’s defense and space business has gone through several difficult years. Fixed-price contracts were squeezed by inflation, contributing to a $5.4 billion operating loss in 2024 and a $128 million loss in 2025. The division has not recorded a full-year profit since 2021.

More recently, the business has shown improvement. Boeing’s defense and space unit posted a $218 million operating profit in the first half of 2026 on sales of $15.1 billion — just under a third of Boeing’s total first-half sales, which came in just under $47 billion.

The size of the F-15 contract gives Boeing a long runway of predictable revenue tied to an established aircraft program, a steadier base for a division still working back from its 2024 and 2025 losses.

BA stock has had a volatile year. Heading into Tuesday, the shares were down 3% for the year and 7% over the past 12 months. The stock climbed above $240 in early August before easing back as crude oil prices moved from around $77 to $86 a barrel in recent weeks.

Jet fuel costs remain an important concern for airlines, which can affect aircraft demand and Boeing’s commercial business outlook. Boeing’s shares had already fallen below $190 in March before recovering above $240 in May. The company’s commercial airplane segment still remains the main driver of day-to-day trading in BA stock.

The F-15 agreement covers potential work across the full fleet through 2037 — from aircraft first fielded in the 1970s to the newest F-15EX Eagle IIs — and stands as one of Boeing’s largest defense service contracts in years.
