The McDonnell Douglas F15 Eagle is an American twinengine, allweather tactical fighter aircraft designed by McDonnell Douglas (now part of Boeing). Following reviews of proposals, the United States Air Force selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.

The Eagle has been exported to Israel, Japan, and Saudi Arabia. The F15 was originally envisioned as a pure airsuperiority aircraft. Its design included a secondary groundattack capability that was largely unused. The aircraft design proved flexible enough that an improved allweather strike derivative, the F15E Strike Eagle, was later developed, entered service in 1989 and has been exported to several nations. Several F15 variants have been produced.

The F15 can trace its origins to the early Vietnam War, when the U.S. Air Force and U.S. Navy fought each other over future tactical aircraft. Defense Secretary Robert McNamara was pressing for both services to use as many common aircraft as possible, even if performance compromises were involved. As part of this policy, the USAF and Navy had embarked on the TFX (F111) program, aiming to deliver a mediumrange interdiction aircraft for the Air Force that would also serve as a longrange interceptor aircraft for the Navy.

In January 1965, Secretary McNamara asked the Air Force to consider a new lowcost tactical fighter design for shortrange roles and close air support to replace several types like the F100 Super Sabre and various light bombers then in service. Several existing designs could fill this role; the Navy favored the Douglas A4 Skyhawk and LTV A7 Corsair II, which were pure attack aircraft, while the Air Force was more interested in the Northrop F5 fighter with a secondary attack capability. The A4 and A7 were more capable in the attack role, while the F5 less so, but could defend itself. If the Air Force chose a pure attack design, maintaining air superiority would be a priority for a new airframe.
