SAAB J-32 Lansen

J32E


On 20 December 1948 Saab received the go-ahead to proceed with the design and the construction of a mock-up of a conventional single-engined aircraft designated the 1150 or Aircraft 32.

Design was initiated to provide the Swedish air force with an all-weather attack aircraft powered by two de Havilland turbojets, but the promise of an indigenous, and consequently cheaper engine brought cancellation of the original project. The design was drawn up around the new Swedish powerplant, but development delay of this engine threatened Saab's programme and, instead, it was to be given a go-ahead following a decision to power the aircraft by a Rolls-Royce Avon turbojet.

The type is a two-seat cantilever low-wing monoplane with powered controls, retractable tricycle landing-gear a single wheel on each unit). The main wheels retract inwards into the fuselage and the nosewheel retracts forward. The crew of two accommodated in tandem on ejection seats in a pressurised cockpit. Its wing incorporated 35 degrees of sweepback and like that of the Saab-29 before it was evaluated in scaled-down form on a Saab Safir trainer. Conventional ailerons, elevators, rudder, Fowler flaps and variable incidence tailplane were fitted, and four air-brakes on the sides of the rear fuselage.

 

Four prototypes of the Saab-32 design were ordered, and following the maiden flight of the first pro-totype on 3 November 1952, on 25 October 1953, the 32A became the first Swedish-built airplane to break the sound barrier.

Production of the A 32A Lansen (Lance) started in 1953, an all-weather attack aircraft powered by a Swedish-built version of the Rolls-Royce Avon Series 100, developing 4500kg afterburning thrust. The first production 32As were delivered to Fl7 Wing at Kallinge in December 1955. A total of 285 A-32As were built.

The first prototype of the 32B - an all-weather interceptor equipped with a more powerful engine, heavier armaments, navigational and homing radar, a sophisticated fire-control system and an autopilot designed by Saab, flew for the first time on 7 January 1957 (153 built).

 

 


When production of the A 32A ended in mid-1958, deliveries began almost immediately afterwards of the J 32B all-weather/night fighter. It introduced the Flygmotor RM6B turbojet, a licence-built version of the Rolls-Royce Avon Series 200 which developed 6900kg afterburning thrust, providing much enhanced performance. Production of the J 32B ended in early 1960.

Built almost in parallel with this version was the S 32C reconnaissance aircraft with a modified nose to carry advanced cameras as well as radar surveillance equipment. The 32C was a reconnaissance aircraft equipped with five separate cameras (37 built). The 32C made its first flight on 26 March 1957.

When production ended with delivery of the last J 32B, on 2 May 1960, a total of 447 Saab-32s of all versions had been built for the Flygvapen. By 1993 only a handful of Lansens remained in military service, chiefly with the Forsokscentralen (test and trials unit) of the Flygvapen. Two-seat J 32B and J 32D target tugs are in use along with 14 specially modified J 32E electronic warfare 'aggressor' aircraft. These aircraft are operated by F13M, based at Malmslatt, with a permanent detachment at the RFN's Norland missile test range in Videsl, Lapland. Three J 32B target-tugs were formerly operated by civilian contractor Swedair, but reverted to air force control.

The last of the type being retired from active service in 1973.
