The Saab 32 Lansen (English: "The Lance[Nb 1][3]) is a two-seat, transonic military aircraft designed and manufactured by the Swedish aircraft manufacturer Saab AB. Development of the Lansen commenced in late Autumn 1946 as a successor to the Saab B 18/S 18 attack aircraft, although an initial contract for the design and mockup of Saab's proposed P1150 design was not issued until December 1948. As the design was refined, plans to use the indigenous STAL Dovern turbojet engine were put aside due to technical difficulties in favour of the license-built Rolls-Royce Avon powerplant instead. On 3 November 1952, the first prototype performed its maiden flight; following flight testing and several refinements, series production of the type commenced during the following year. Deliveries of the Lansen to the Swedish Air Force (Flygvapnet) took place between 1955 and 1960. It was the service's first twin-seat jet aircraft as well as the first to be equipped with an integrated search radar. Three principal variants of the Lansen were produced, these being for attack (A 32A), fighter (J 32B), and reconnaissance (S 32C) missions. Later built aircraft were equipped with a more powerful model of the Avon engine and increasingly capable electronics. During its lengthy operational life, the Lansen also served in secondary roles, including as an electronic warfare platform, target tug, and research aircraft. The majority were retired during the 1990s following the end of the Cold War. The Saab 32 Lansen had a straightforward general arrangement, being one of the first aircraft in the world to be specifically developed to fly attack missions. From the outset, it was designed to effectively accommodate the installation of electronic warfare and various weapons systems. The aircraft could be armed with a total of four 20 mm cannon, as well as wing pylons for various calibers of rockets and assorted bombs. The J 32 variant carried four 30 mm ADEN cannons while the A 32 ("A" stands for attack) had an armament of four 20 mm Bofors m/49 cannon hidden under flaps in the nose. The J 32 differed substantially from the other variant, Saab describing it as "to all intents a new aircraft", being fitted with a more powerful engine and newer armaments and different radar.
