The United States (US) looks set to approve a $3 billion agreement to support Saudi Arabia’s in-service F-15 fighter fleet, following a request from its Gulf ally.
On February 4, 2026, the US State Department approved a sustainment package for the Royal Saudi Air Force’s F-15s, while the Defense Security Cooperation Agency delivered the required certification notifying Congress.
According to the State Department, Saudi Arabia has requested the purchase of non-major defense equipment items, with the estimated cost placed around $3 billion.
The agreement includes spares and repair parts, consumables and accessories, repair and return support, ground and personnel equipment, classified and unclassified software, classified and unclassified publications and technical documentation, and personnel training and training equipment.
Additionally, the $3 billion package will include US government and contractor engineering, technical and logistics support services, and other related elements of logistics and program support.
The US noted that the proposed sale will “enhance Saudi Arabia’s capability to deter current and future threats by providing sustainment and training support for the Royal Saudi Air Force’s F-15 fleet”.
“This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a Major non-NATO Ally that is a force for political stability and economic progress in the Gulf Region,” said a spokesperson for the State Department.
The backbone of the Saudi fighter fleet is composed of over 200 US-made F-15C/D/SA Eagle fighters.
The first F-15 to be delivered to Saudi Arabia arrived in 1978, just two years after it was formally inducted by the United States Air Force.
In November 2025, US President Donald Trump met with the Saudi Crown Prince Mohammed bin Salman, when they signed several important agreements.
Among them, President Trump approved a major defense sale package, including future F-35 deliveries to Saudi Arabia.
