The J29A is a single-engine jet fighter developed by SAAB in the late 1940s. One of the main design features of this aircraft is its swept-back wings, which were designed after SAAB acquired German documents from the war that proved that swept-back wings were necessary when trying to achieve higher speeds. The J29A also features a Swedish license-built version of the British de Havilland Ghost engine. The armament consists of four 20 mm akan m/47C, a license-built copy of the British Hispano Mk V, but with a lower rate of fire. The first prototype flew in 1948, and the aircraft then proceeded to enter service in the Swedish Air Force, Flygvapnet, in 1951. It remained in service until 1962 and never saw any combat use.

Introduced in Update 1.95 "Northern Wind", the J29A has a very different playstyle compared to the preceding J21RA. The J29A relies more on teamwork with other jets, as it is inadequate at accelerating and getting to high speed will take a while compared to a lot of opposing jets it will face. The J29A bleeds speed in turns and will have a hard time regaining that speed, making it more recommended to do hit and run passes on unsuspecting enemies. The J29A can turn well when having speed, so it is not atrocious at turning for dogfighting, but prolonged dogfighting puts the aircraft in danger. Being armed with four Akan m/47C 20 mm cannons, the J29A has greater firepower the J21RA, with plenty of ammo to compensate for poorly aimed shots.
