These walk-around photos were taken at Flygvapenmuseum at Malmen outside Linköping in 2017, 2019 and 2022. They show a Saab S 29C Tunnan, individual number 29970, coded F 21-20 in the markings of F 21 Luleå — the dedicated reconnaissance variant of Western Europe's first swept-wing fighter, and one of the earliest aircraft to enter Flygvapenmuseum's collection. The S 29C was the unarmed reconnaissance version of the Tunnan, produced in 76 examples between 1954 and 1956. In place of the four 20 mm cannon of the fighter variants it carried seven cameras, and it was the first Swedish combat aircraft to be equipped with a rear warning system to detect attacks from behind. Despite being unarmed it flew at the same speeds as the fighter — the S 29C was the first Swedish reconnaissance aircraft capable of supersonic flight at low altitude, making it exceptionally difficult to intercept. Individual 29970 was delivered in 1956 and served as a reconnaissance aircraft for ten years before passing to the Target Flight Division at F 3 Malmen, where it was used until 1970. It then became part of the early aviation history collections at Malmen that would later form the foundation of Flygvapenmuseum — making it one of the longest-serving exhibits in the collection.
