The term entered normal use in the United States Navy[4] by the end of the 1970s, becoming the official[5] description of the new McDonnell Douglas F/A-18 Hornet. In 1983, the U.S. Navy even renamed each existing Fighter Attack Squadron to Strike Fighter Squadron to emphasize[6] the air-to-surface mission (as the "Fighter Attack" designation was confused with the "Fighter" designation, which flew pure air-to-air missions).
This name quickly spread to non-maritime use. When the F-15E Strike Eagle came into service, it was originally called a "dual role fighter",[7] but it instead quickly became known as a "strike fighter".
