These walk-around photos were taken at Flygvapenmuseum at Malmen outside Linköping in 2017, 2019 and 2022. They show a de Havilland Venom NF.51, designated J 33 in Swedish service — Sweden's first jet-powered night fighter, and the aircraft that replaced the piston-engined de Havilland Mosquito (J 30) at the country's sole dedicated night fighter wing, F 1 at Västerås. The Venom was a direct development of the Vampire, sharing its distinctive twin-boom layout but featuring a thinner, redesigned wing with integral fuel tanks and the more powerful Ghost engine, giving it a significant performance advantage over its predecessor. The NF.51 was the export night fighter variant, a two-seat aircraft equipped with AI radar for all-weather interception.
Sweden ordered 60 NF.51s in January 1951, with deliveries starting from late 1952 and the type entering service at F 1 in 1953. The early aircraft arrived with flight restrictions due to wing spar issues, but once resolved the J 33 served effectively in the night interception role throughout the 1950s. It was replaced by the SAAB J 32B Lansen from 1959 onwards. Individual 33025, coded E and marked with the insignia of F 1, was delivered to the Air Force in 1953 and withdrawn in 1960. It subsequently passed to Svensk Flygtjänst, registered SE-DCD, where it was used for target towing before being preserved at Flygvapenmuseum.
