Air Force Expands Fighter Programme to 268 Aircraft

The US Air Force is seeking to nearly triple its planned F-15EX Eagle II fleet, increasing the programme from 98 to 268 aircraft under the fiscal 2027 President’s Budget. The expansion would add 170 jets and extend procurement through fiscal 2031, with an estimated acquisition cost of $36.93 billion. The Air Force aims to replace its ageing F-15C and F-15D fleet with the F-15EX Eagle II, which is derived from the F-15QA developed for Qatar. This development was first reported by Defence Industry Europe.
