The Saab 29 Tunnan ("The Barrel"), colloquially Flygande Tunnan, or The Flying Barrel in English,[a][b] is an early jet-powered fighter aircraft designed and produced by the Swedish aircraft manufacturer Saab. 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 after the Second World War, only being preceded in Western Europe as a whole by the Messerschmitt Me 262 built during the conflict.
The J 29A fighter was the first model to enter service and was followed by the J 29B and J 29E fighters, and finally the afterburner-equipped J 29F fighter, which was the final variant built. There was also a dedicated reconnaissance variant, the S 29C. Between 1950 and 1956, 661 Tunnans were completed, the largest production run for any Saab aircraft
