Saab's J21R jet fighter retained the long legs of the J21A propeller plane, and compared to the otherwise rather similar Vampire it seems to stand twice as high! This machine is actually a surviving J21A, 21286, modified to represent the extinct jet variant. 64 J21Rs were originally constructed and they were soon converted to A21R attack aircraft.

At the time operated by F 7 at Såtenäs, this early Viggen ended up on the dump at Ängelholm after instructional use in F 10 marks. The AJ37 was a single-seat ground-attack fighter aircraft, with a secondary fighter role, many undergoing electronic upgrades around 1992 to AJS37 in order to carry Sidewinder missiles. Most decommissioned by 1998
