The SAAB model 29 was a jet fighter designed by SAAB after the Second World War and it was in the era that the jet emerged. The Saab design team started in 1946 led by Lars Brising, using German research data on the swept-wings, a new phenomenon to  "postpone" the sound barrier. The SAAB 29 prototype flew for the first time on 1 September 1948 and the test pilot was an Englishman, Robert Moore who had some experience with jets. Four prototypes were made. It later got the designation J29 Tunnan ("Flying Barrel"). 

Quickly, the J29A went into production in 1951 for the Swedish Air Force as the Cold War emerged and Sweden remaining "neutral". 

The first J29A had a 4 canon Hispano armament and was delivered May 1953 to F13 wing at Norrkoping. Training pilots was quite difficult with no two seater and adverse Dutch roll behaviour during landing. Many accident occurred over the years. The J29A had limited fuel capacity and thus range and 224 aircraft were manufactured till 1953. The J29B got a "wet wing" with more fuel and first flew March 1953 with 332 built. 

Than followed the J29D with afterburner but only 1 made and than the J29E fighter. The wing got a "saw tooth" / outboard wing leading edge extension for higher speed, a wing fence and the slat was deleted. Twenty-nine J29E were built with the new wing. 

The S-29C was a reconnaissance version with usually 5 camera's fitted in the lower fuselage nose with 76 aircraft manufactured.

The J29F was to become the final standard with the Svenska Flygmotor RM2B engine and afterburner. Some 210 older J29B/E Tunnans were converted from 1954-1956 to the new "F" standard and the new wing fitted. The first J29F flew March 1954 and it could also fire the AIM-9B Sidewinder ("Rb-24" licensed) missile. 

A special assignment for the Swedish J29 was when several aircraft were stationed in the Republic of Congo for a UN peacekeeping mission (ONUC) in 1961-1962 to fight the rebel Katanga force. 

Also, some 30 refurbished J29F Tunnans were sold to Austria in 1961 where they remained in service until 1972. It was the only foreign sale of the type but bear in mind that Sweden ensured it kept a "neutral position".

The J29F remained in Swedish operational use as a fighter until 1967 but some aircraft soldiered on as target tugs and various smaller roles.
