Sweden thus became one of the first nations with jet fighters in their air force. The early version of Vampire had a very limited endurance, and therefore were of limited use as an air defence asset.
During their first years in service, they had their wingtips clipped, almost to Mk 5 standard, but with a span 1 cm shorter.
When F 13 were reequipped with J 29 Tunnan, their J 28A Vampires were transferred to F 3 at Malmslätt, where they served from 1950 to 1953. Their last years in air force service were at the air force academy, F 20, at Uppsala, where they were retired in 1956.
About 50 of them were exported to The Dominican Republic and Austria.
The wings equipped until 1952 with J 28B were F 8 at Barkarby outside Stockholm, F 9 at Säve outside Gothenburg, F 18 at Tulling outside Stockholm, F 10 at Ängelholm, F 15 at Söderhamn and F 4 at Frösön outside Östersund. Some got them directly from the manufacturer, some from other wings as they were reequipped with Tunnan.
J 28B became outdated as a air defence fighter early on, and remained in front line service as such only until 1955 at F 18 and F 4.
17 were sold to The Dominican Republic in 1957.
Attack armament, apart from the four 20 mm guns, was eight rockets with could be fired in pairs of four at a time.
The designation S 28 was never adopted officially, as they
never got any cameras or other modifications. And as
Spitfire had superior performance in several regards it
would have been useless.
In 1953 30 de Havilland Vampire Trainer T 55 were
delivered to the Central Flying School F 5, at Ljungbyhed.
Originally they were designated J 28C.
Many of them were passed on to fighter wings.
In 1954, the air force started flight training on jet aircraft. As F 5 still had grass runways, the J 28Cs were based at F 14, Halmstad. In 1956 they moved back to F 5.
The J 28Cs were redesignated Sk 28C-1 (as is proper for a
trainer), a further 15 Vampire T 55s were delivered in
1955-56 and designated Sk 28C-2, as they had different
canopies, fins and avionics. The Sk 28C-1s were rebuilt to
Sk 28C-2 standard, but not redesignated.
In 1959, twelve J 28B were rebuilt into two seat trainers, with front fuselages purchased from England. Their designation became Sk 28C-3.
As the Vampire was very easy to fly, single seaters were
also used as trainers.
Both the single and two-seat Vampires were retired in
1968, after beeing replaced by Sk 60, Saab 105.
