The USAF had planned to replace all of its air superiority F-15s with the Lockheed Martin F-22 in the 2010s, but the severely reduced F-22 procurement forced the USAF to operate the F-15C/D into the 2020s. Several additional F-15 variants have been produced. The aircraft design proved flexible enough that an improved all-weather strike derivative, the F-15E Strike Eagle, was later developed, entered service in 1989 and has been exported to several nations. Its design included a secondary ground-attack capability that was largely unused. The F-15 was originally envisioned as a pure air-superiority aircraft. The Eagle has been exported to numerous countries including Israel, Japan, and Saudi Arabia.
