The Saab 32 Lansen (German lance , military designation Saab A 32A , Saab J 32B and Saab S 32C ) is a single-engine fighter aircraft from the Swedish manufacturer Saab . The two - seat low - wing aircraft was in service with the Swedish Air Force until 1997. A total of 452 aircraft were manufactured.
development
The preliminary investigations that led to the Saab 32 began as early as 1946 when a replacement for the existing fighter-bomber, reconnaissance and night fighter aircraft was sought. However, Saab did not receive approval for the design and construction work until December 1948. Initially, a twin- engine solution was investigated, but the improved performance data of the new jet engines eventually led to Project 1150, a single-engine aircraft. Arthur Bråsjö was the project manager who first used a computer as a design aid . In application of the work by Adolf Busemann , which has since become generally known, the leading edges of the wings of this aircraft, as well as those of the conventional tail unit, received a sweep of 39 °. The Saab 32 received a retractable nose wheel landing gear with low-pressure tires and for the first time had electronic equipment that was largely developed in-house. Four prototypes were initially ordered.
Saab A 32
On November 3, 1952, the first flight took place , which was carried out by chief test pilot Bengt R. Olow. On October 25, 1953, the sound barrier was broken in the incline flight. The attack aircraft A 32A was armed with four 20 mm Bofors m / 49 cannons with 180 rounds of ammunition each and could also carry rockets and bombs. Originally only a PN-50 / A (pulse navigation radar) was on board, which is a kind of ADF . A Saab BT9C served as a reflex sight .
With a real on-board radar, which had been developed by CSF and was given the designation PS-431 / A, the machine could be used in any weather. However, only about a quarter of the Saab A 32 was equipped with a radar. One of the most important weapons was the Saab Rb 04 anti-ship missile , which was specially made for the Saab 32. A maximum of three of these weapons could be carried. The target was activated by the on-board radar.
Delivery to the troops began in December 1955, when the F 17 unit, then still in Ronneby , was equipped with the Saab 32. There it replaced the Saab T 18B . Between 1955 and 1957, a total of 284 Saab A 32A machines appear to have been delivered.
It was used in units F 17 Kallinge , F 7 Såtenäs , F 14 Halmstad , F 6 Karlsborg and F 15 Söderhamn .
Saab S 32
The Saab S 32C reconnaissance version was first flown on March 26, 1957. Instead of the weapons, she carried a total of six cameras. This version received an improved radar PS-432 / A, which had an increased range compared to the PS-431 / A. The first machines were delivered to the F 11 in Nyköping in 1960 . A total of 44 pieces of this version were made.
They were also used on the F 12 Kalmar , F 21 Luleå and F 4 Frösön .
Saab J 32
The improved version J 32B had a more powerful engine and armament, which consisted of four 30 mm Aden m / 55 cannons. A PS-42 / A, which had the option of 3D display, was used as the radar. The antenna swivel range was 60 ° to each side and + 60 ° / −30 ° up / down. The radar data and the information from the Hughes AN / AAR-4 IR system could also be displayed in the HUD (head-up display) Sikte 6A. For the first time, the pilot also received a radar display. The first flight of this version took place on January 7, 1957. Machines of the type were delivered to the F 1 - at that time still in Västerås - and the F 12 in Kalmar between 1958 and 1960 . The variant J 32D (six pieces) was a conversion to a target tow plane, and the J 32E (15 pieces) was an ECM variant of this type that was also created by conversion . A total of 120 J 32 machines were built.
It was used on the F 1 Hässlö F 12 Kalmar , the F 21 Luleå and F 4 Frösön .
