This had the single stage Griffon engine in a basically Seafire L Mk III airframe but with wing root fuel tanks, retracting tailwheel and larger tail of the Spitfire VIII. It had folding wings and the two cannon, four m-gun armament. The arrester hook was often of the “sting” type, whereas previous marks had used a “v” frame hook. The XV could carry a 500lb bomb and the last 50 had the teardrop hood. 390 produced.
