The aircraft carrier is briefly shown as herself, despite the postwar addition of a large angled flight deck and a massive Type 984 "searchlight" radar; the same ship is also used to depict HMS "Ark Royal" sailing from Gibraltar. All flying from both carriers was filmed aboard – clearly marked with her postwar pennant number R06 – and three surviving Fairey Swordfish aircraft were restored, of which two were flown from her flight deck. These three aircraft now form the core of the Royal Navy Historic Flight. A 2010 article in "Aeroplane" identifies the Swordfish flown in the production: "LS326", carrying its true serial, was marked as "5A" of 825 Naval Air Squadron, while "NF389" was marked as "LS423" / "5B". The same actor plays the leader of the Swordfish attack from HMS "Victorious" (in reality, Lt Cdr Eugene Esmonde VC, DSO), and also the pilot from HMS "Ark Royal" who later fired the torpedo which crippled "Bismarck"s steering gear, (in reality Lt John Moffat RNR).
