The 91st Tactical Fighter Squadron, also known as the "Blue Streaks," was a unit of the United States Air Force that operated during the Cold War era. The squadron was based at RAF Bentwaters in Suffolk, England, and was assigned to the 81st Tactical Fighter Wing. The 91st Tactical Fighter Squadron was first activated in 1942 as the 91st Pursuit Squadron, and saw action in Europe during World War II. The squadron was later reactivated as the 91st Tactical Fighter Squadron in 1958, and began operating F-100 Super Sabre aircraft. During the 1960s and 1970s, the Blue Streaks played an important role in the Cold War, operating in support of NATO forces in Europe. The squadron was responsible for providing close air support to ground forces, as well as conducting air-to-air combat operations. In 1980, the 91st Tactical Fighter Squadron transitioned to the F-4 Phantom II aircraft, which it operated until its deactivation in 1991. During this time, the Blue Streaks continued to support NATO operations in Europe, and also saw action during the Gulf War in 1991.
