The Saab 29 Tunnan is a Swedish fighter that was designed and manufactured by Saab in the 1940s.
It was the second turbojet-powered combat aircraft to be developed in Sweden, the first being the Saab 21R, and it was the first Western European fighter to be produced with a swept wing post World War II, only being preceded in Western Europe as a whole by the Me 262 built during the war.
Despite its rotund appearance, from which its name is derived, the J 29 was fast and agile and served effectively in both fighter and fighter-bomber roles into the 1970s.
Four prototypes built in 1949–50.
Fighter, 224 built from 1951 to 1954, later series had wing-mounted dive brakes moved to the fuselage, ahead of the main landing gear doors.
Fighter, 332 built 1953–55; featured 50% larger fuel capacity and underwing hardpoints to carry bombs, rockets and drop-tanks.
Same aircraft as the J 29B, when serving with attack units.
Reconnaissance, 76 built from 1954 through 1956, five cameras mounted in a modified nose.
Later modified with the improved wing design introduced on the J 29E.
Single prototype to test Ghost RM 2A turbojet with 27.5 kN (2,800 kgp/6,175 lbf) afterburning thrust; ultimately converted to J 29 F standard.
Also tested with four m/55 AKANs.
Fighter, 29 built in 1955; introduced an improved wing design with a leading edge dogtooth to increase the critical Mach number.
Fighter, 308 aircraft converted from available stocks of B and E model airframes from 1954 to 1956; featured the afterburning Ghost and dog-tooth wing; all remaining aircraft were further modified in 1963 to carry a pair of US-designed AIM-9B Sidewinder heat-seeking air-to-air missiles, built by SAAB under license as the Rb 24.
