The Blackburn B-25 Roc was a British Second World War-era Fleet Air Arm fighter aircraft designed by Blackburn Aircraft Ltd. It took its name from the mythical bird of the tales of the Arabian Nights, the Roc.
Although intended for carrier use, Rocs only served alongside Skuas in two land-based squadrons of the Fleet Air Arm between February 1940 and August 1941. During the Allied campaign in Norway a small contingent of Rocs travelled with 800 and 803 squadrons onboard HMS Ark Royal. Skuas and Rocs flew both fighter sweeps and bombing sorties over the English Channel during Operation Dynamo, and Operation Ariel, the evacuation of Allied forces from Dunkirk and other French ports.
