The 617 squadron was first formed during World War II and carried out Operation Chastise, a legendary air raid that used a new type of bomb to strike dams in the Ruhr region, Germany's industrial heartland.
The raid earned the squadron the nickname "Dambusters." It was disbanded in early 2014 but reformed in 2018 to become the UK's first F-35 squadron, using the vertical takeoff and landing version, the F-35B.
