These walk-around photos were taken in one of Flygvapenmuseum's storage facilities in 2019. They show a de Havilland DH.115 Vampire Trainer Mk 55, designated J 28C in Swedish service — the two-seat training variant of Britain's iconic twin-boom jet fighter, and the aircraft that revolutionised pilot training in the Swedish Air Force. Where the single-seat J 28A and J 28B had required pilots to transition straight from propeller trainers into solo jet flight — a demanding and sometimes fatal leap — the J 28C offered a proper jet trainer with side-by-side seating for instructor and student, dual controls, and the same basic airframe and handling characteristics as the fighters they would go on to fly. Sweden ordered 57 J 28Cs in several batches from 1952, initially using them as fighters at some wings before their true potential as advanced trainers was recognised. From 1954 Krigsflygskolan at F 5 Ljungbyhed began using them for the final phase of basic flight training, and by 1955 the Vampire had completely replaced the older piston-engined SK 16 Harvard. Notably, all Swedish Vampires — including the J 28C — retained the designation prefix J rather than Sk, reflecting the Air Force's view that even trainer variants were combat-capable aircraft. The J 28C remained in service until 1968, the last of the Vampire family to serve in Sweden. This example, Fv 28451, is part of Flygvapenmuseum's collection.
