Air Force releases sources-sought for F-15EX engine provider

The Air Force this week released a sources-sought notice seeking companies to provide the propulsion system for the F-15EX, which will replace the aging F-15 C/D fleet.

The call for market research comes after the service in January announced its intent to sole-source an engine contract to General Electric, which builds the F110 propulsion system that powers most of the F-15E fleet.

Today's notice states that the service plans to buy up to 461 engines, with initial deliveries in June 2023. Responses are due June 8.

Boeing builds the F-15, and the service has indicated it could buy as many as 144 jets.
