F111s

The F-111 Aardvark was an American variable-sweep wing strategic bomber, reconnaissance, and tactical strike aircraft. Developed by General Dynamics, it first flew in 1964 and entered service in 1967. The F-111 was designed for interdiction and close air support roles, capable of high-speed, low-level penetration of enemy airspace. Its distinctive variable-sweep wings allowed it to change wing angle for optimal performance at both high speeds and low speeds, providing flexibility for different mission profiles.

The aircraft was powered by two Pratt & Whitney TF30 turbofan engines. Its advanced avionics suite included terrain-following radar, enabling it to fly at very low altitudes and high speeds, making it difficult to detect. The F-111 served with the United States Air Force, Royal Australian Air Force, and the Royal Air Force, though the RAF's variant, the F-111K, was canceled.

Despite its advanced capabilities, the F-111 program faced challenges, including high development costs and early operational issues. It saw combat in Vietnam, where it was used for bombing missions, and later in operations over Libya and Iraq. The F-111 was retired from USAF service in 1998, replaced by aircraft like the F-15E Strike Eagle and the B-1 Lancer. The F-111's complex design and role in Cold War strategy made it a significant, albeit sometimes controversial, aircraft in aviation history.
