The Saab 29 was introduced about a year after the Saab 21R's entry into service, after which time all 21Rs were converted to attack aircraft.

Saab 21 (854 words)
After a specification from the air force, Saab presented a projected fighter (L-12) in 1939, powered by a 1215 hp Bristol Taurus radial engine giving it a maximum speed of 605 km/h.
As Saab at this time was busy developing and manufacturing the bombers B 17 and B 18, both L-12 and L-13 were put on the back burner.
Saab wanted to gain experience with jet engines, and decided in 1945 to convert a few J 21A-1s to jet power powered with de Havilland Goblin 2 engines which were ordered from Enland.
