f111

The F-111 Aardvark was an American tactical bomber, reconnaissance aircraft, and — in its later variants — a low-level interdictor and tactical strike aircraft that served with the United States Air Force and the Royal Australian Air Force. Developed by General Dynamics, it was a product of the TFX program, which aimed to create a common fighter for all branches of the U.S. military. However, the F-111's complex design and shifting requirements led to significant development challenges and cost overruns.

Its most distinctive feature was its variable-sweep wing, allowing for high speed and maneuverability at low altitudes when wings were swept back, and efficient cruising at high altitudes with wings extended. This capability made it well-suited for its intended role of penetrating Soviet air defenses. The F-111 also incorporated an internal weapons bay and could carry a variety of munitions, including bombs and missiles.

The F-111 saw combat during the Vietnam War, where it was primarily used for strategic bombing missions, and later in the Gulf War. While it proved effective in certain roles, particularly low-level penetration, its operational history was marked by some notable incidents and a relatively high attrition rate in Vietnam. The F-111 was eventually retired from service by the USAF in 1996 and by the RAAF in 1999, replaced by other aircraft like the F-15E Strike Eagle and the F-117 Nighthawk.
