Second, instead of guns “Bofors” M-49, the fighter was set to English 30-mm cannon “Aden”, turret type, ammunition 90 rounds per gun. To reduce the weight of the structure from the protective folds refused, and spent cases were collected in hillsoboro. The composition of the suspension arms will change as well. Quantity of external hardpoints reduced to four. In the nomenclature of the weapons included missiles “air — air” Rb-324, which was a licensed copy of the American UR AIM-9 “Sidewinder”. The fighter had two basic options weapons: 4 SD Rb-324 or two such missiles plus two containers with 75-mm NAR.
Thirdly, on the basis of the main tasks of the interceptor, significant changes were the avionics. The aircraft was equipped with three-coordinate radar PS-42/A, which is a further development of the station of the PS-431/A, which carried the Swedish firm Ericsson. PS-42/was the area of the support in azimuth ± 60°, and in elevation from +60° to -30°, the range of the target was about 30 km away.
In addition to the new radar, the fighter was equipped with such an innovation as the weapons control system Sikte 6A on the basis of computers. Part of the interceptors were equipped with infrared station AN/ААR-4 firm “Hughes” mounted under the left wing just before landing gear. The weapons control system displays information received from radar and IR stations, as well as the navigation information on the monitor screen in the cockpit and operator. Thanks to modern avionics the aircraft could attack a target without visual contact with her.
Royal Swedish air force ordered 120 interceptors, and in the period from 1958 to 1960 such equipment was equipped 7 squadrons (118 machines, serial numbers 32501 — 32620). Interesting fact: with the advent in the late 1950-ies supersonic fighter “Draken” “larceny” continued to be in service before 1973. Obviously, the reason is maneuvering characteristics of these aircraft. For all its virtues, “Fight” could not dogfight maneuver as fast as “Lansen”.
The last modification that produced commercially, was photo reconnaissance and patrol aircraft UAV S 32C.
Structurally it differed little from the shock option. The biggest changes were the forward fuselage, where instead of cannon armament was installed photographic equipment.
The first flight of a new version of “Lansen” was held on 26 March 1957. In the period 1958 — 1959 was released 44 machines of this modification. All the scouts were part of the only intelligence wing F11, based in Nykoping. Several S32Cs in 1959 — 1961 were stationed in part F 21 — the Northern wing of the Air force, stationed in Cal. During the operation the total flight S32C exceeded 75 600 hours. Armed, they stood until 1978, until they were replaced came photo-reconnaissance variant “Viggen” SH37.
Scout got an improved radar, the PS-432/A, having increased target detection range (up to 100 km forward and up to 50 km on both sides). The station was optimized for search and detection of surface targets, and to analyze the results of her exploration of the screen was filmed with a special camera.
Compartment equipment could accommodate up to six cameras for different purposes, although in operation their number does not exceed four. The original standard included two cameras English production (firm A. G. I. of Croydon): SKA.-17 — for shooting from low altitudes (focal length 130 mm) and SKA.-18 for high-altitude photography (focal length 920 mm). Photographing the first pair of cameras was carried out from altitudes from 100 to 1200 m, the second from 3 to 10 km.
But that scout was built in one copy only. Military he was not satisfied, so production aircraft had a different line of photographic equipment.
By 1962, spy planes equipped with advanced cameras for the placement of which was necessary to modify the corresponding compartment, increasing its volume. In fotootchet installed two high-altitude cameras SKA.-23 (in the original — “Fairchild” K-47 US made, focal length — 600 mm), optimized for night photography, as well as a wide-angle camera SKA.-15 (Williamson F-49 Mk.2). Both types were intended for shooting in night conditions, with altitudes of over 1000 m. SKA.-23 equipped with a stabilization system. For high-altitude shooting was intended and the camera “, Jugner” FL-S. 2, installed behind the left SKA.-23.
For low-altitude shooting used a different set of equipment, including two or three camera CA.-16 (produced by “Winter”) with a focal length of 100 mm.
For illumination of objects to be used up to twelve 75-kg flare, suspended on external suspension units. Also, the scout could be fitted with the device of the emission dipole reflectors BOZ-3.
Designed several modifications of the aircraft. This is a daily single-seat fighter aircraft J 32АD, who had no radar and armed with five guns: four 20 mm and one 30 mm caliber. But further development did not go. The Swedish government has decided to buy in the UK 120 fighter “hunter”, who served in the Swedish air force under the designation J34.
Was also developed an improved version of the interceptor — J32U — with a more powerful engine RA 19R is the “rolls Royce”. Designed a new, more subtle (6%) wing with a sweep of 40° and tail that would allow it to fly at supersonic speeds. There was also the installation of the rocket boosters.

But this option is not out of the design stage. In 1958, the final decision on the replacement of “Lansana” eight years later, new aircraft “Viggen”. However, the technical difficulties encountered when creating a new machine, and did not rule out other scenarios. Was seriously considering the purchase of foreign technology, potential candidates appeared: a-4 “Skyhawk”, A-7 “Corsair”, F-104 “Starfighter”, F-5 “freedom fighter”, the F-4 “Phantom” and “Bakanas”. All applicants, except the last two, were excluded from the list as not meeting the entire list of requirements. “Phantom” was very expensive, the money could build more than two hundred modernized “larsanov”. And the new “Viggen” by criterion “cost — effectiveness” was to surpass and “Phantom”, and “Bakanas”. Therefore, as an interim solution in 1965 was considered finalized, interceptor J-32V in shock AND 32B, having an enhanced design, a more powerful engine RM-6S and a set of weapons designed for “Viggen”. Delivery of this option could begin in 1972, but the “Viggen” “ripe” in time: the first strike aircraft was delivered to the Swedish air force June 21, 1971.
During the serial production was released in a total of 456 aircraft in three main versions. The first Stroy left the fighter-interceptors, in 1973 they were replaced by “Viggen”. Five years later — bombers and scouts.
But the “Lansen” twenty years served his country, though in other guises.
In 1972, six interceptors have been modified to tow targets — J-32D, which operated until 1997. Another 15 cars since 1972, were converted into electronic warfare aircraft, the J-32Е. In the fore part of the former fighter is radar identified a set of G24 is designed for jamming ground-based and naval radar. There were three different stations on the wave band (frequency L, S or C). On under-wing pylons were placed in the containers jamming “Adrian” (frequency S or C) and container jamming against airborne radar “Petrus” (frequency X) and two containers with chaff BOZ-3. The aircraft was used until 1997, including for the training of personnel of the armed forces of Sweden.
Three J-32B was fitted with dual controls and used as training aircraft, as well as for collecting samples of atmospheric precipitation, which had three special containers with paper filters. After the flight filters were removed from containers for further analysis. Interestingly, two of the aircraft are still operated in the interests of the Department of radiation safety of Sweden to collect air samples at high altitudes.
Some planes have long been used as flying laboratories in the development of new aviation technology. For example, in А32А (factory number: 32080) to 1962 — 1963 had a new ejection seat, designed for SAAB 35 “Draken”, and later this machine became a flying stand to develop many new systems “Viggen”.
“Lansen” was not exported and did not participate in armed conflict, though such an opportunity once presented. In 1955 the Israeli government, after unsuccessful attempts to buy American “sabre”, appealed to the Swedish government with a proposal for the procurement of SAAB 32 to counter Egyptian MiG-15 and MiG-17, but was refused.
However, Swedish “spears” were still abroad, but as Museum exhibits. Museum of air power USA (United States Airpower Museum) acquired three “Lansana”, and it was reported that in 2003 it was planned to bring one of them in flying condition. In 1986, the Swedes traded one plane to another rarity is the “Dove” company “De Havilland”. In the UK, the car received a registration and a registration mark G-BMSG. Remaining service life of the airframe before the sale was 1 hour 39 minutes, and almost all of it was consumed during his flight to England. Another car in November of 1999 I flew to Spain, where he is now exhibited in the Museum of the Spanish air force in Madrid. And, of course, in most of Sweden “Lansen” — one of the main exhibits several aviation museums, it can also be seen on the pedestals at the entrance to schools and air force combat units, and then just near the highway. And who knows how many Swedish boys, looking at these monuments of their own history, lit up the dream of becoming a pilot, air traffic controller, aviation engineer or mechanic?
