History Behind Corgi AA32608: Lancaster MkIII, Guy Gibson & 617 Squadron (1943)

In May 1943, Wing Commander Guy Gibson led the legendary 617 Squadron, later immortalised as the “Dambusters.” Their mission, Operation Chastise, was one of the most daring raids of World War II. Flying modified Avro Lancaster MkIIIs, including Gibson’s own aircraft “AJ-G,” the squadron attacked the heavily defended Möhne and Eder Dams in Germany’s Ruhr Valley.

Each Lancaster carried the revolutionary “Upkeep” mine, or bouncing bomb, designed by Dr. Barnes Wallis. To release the weapon effectively, crews trained intensively to fly at night, just 60 feet above the water, at a precise speed and distance from their targets. Innovative spotlights under the fuselage and advanced aiming devices were fitted to ensure accuracy.

The raid breached both dams, unleashing devastating floods that disrupted German industry and communications. Gibson himself flew at the head of the formation, drawing fire to protect his men, and was later awarded the Victoria Cross for his leadership and courage.

The Lancaster MkIII became an icon of the RAF Bomber Command, and Gibson’s 617 Squadron remains one of the most celebrated units in aviation history.
