SK-37 Viggen Trainer
The SAAB 37 Viggen was an aircraft ahead of its time. Its designers used an unorthodox construction which enabled the plane to meet all requirements which had been laid on it and in some parameters even surpass them. The Swedish Air Force ordered several various versions of the Viggen jet fighter, its basic design formed an universal platform which, using a specialized equipment, enabled the plane to be used for different roles.
The first of seven prototype machines took off for its maiden flight on 8 February 1967 with E.Dalström at the controls. The aircraft was powered by a Volvo RM8 turbofan, a licence-built variant of the Pratt & Whitney JT8D with an afterburner and thrust reverser which, in addition to a double-delta wing design, enhanced the plane’s performance the take offs and landings on short airstrips. The avionics of the Viggen was state-of-the-art at the time, the Viggen was the first type to be equipped with a computer with integrated circuits.
The first version of the Viggen to see service with the Flygvapnet was the AJ 37 strike fighter followed consequently by the SK 37 two-seat trainer, the SF 37 reconnaissance version with cameras in a redesigned nose section and the anti-shipping SH 37 with much differing avionics, capable of carrying a range of anti-shipping weapons. Ten years after the first Viggen version entered service, the second generation of the SAAB, the JA 37 dedicated fighter machine came into being. Up to date avionics was used and also a more powerful engine in a slightly longer fuselage. The earlier version got this updated avionics too and this way the AJS, ASFS and ASHS 37 versions were created. A certain number of the two seat airframes were converted to the SK 37 E electronic warfare trainers.
The training version kit contains eleven sprues accompanied by photo-etched details both for the exterior and interior of this version. The decals and marking schemes allow you to build three various airframes which cover all three styles of camouflage schemes worn by the Viggen. We have for you a natural metal Viggen, a standard splinter scheme as well as a two-grey machine.
The Saab J-37 Viggen is a Swedish single-engine, multi-role fighter with duck-shaped lobes. Design work on the machine started in 1964, and the flight of the prototype took place on February 8, 1967. Several major versions of this successful aircraft were produced. The AJ-37 Viggen was developed with a large contribution of American technology and experience under the agreement on cooperation and exchange of military technologies concluded between the two governments. This agreement was part of the security guarantees officially given to neutral Sweden by the US government. In return, the US government demanded the protection of nuclear-warhead UGM-27 Polaris missiles deployed along the west coast of Sweden. Consequently, Viggen was developed faster and at less cost than if it had been constructed solely by Sweden. The first fighter-attack aircraft introduced into service. The letters of the AJ designation come from Attack Jakt - assault-hunting. The AJ 37 had seven knots for the suspension of weapons, two under the wings, two at the air intakes and one central under the fuselage, on which a fuel tank could also be installed. There was still space on the panels for two additional suspension points, which, however, were not used. The next version is the SF-37 Viggen, which is a reconnaissance and photographic reconnaissance machine. The flight took place in 1973. Another version is the SH-37, a sea reconnaissance aircraft. A typical fighter plane is the JA-37 Viggen model, which was flown in 1974. It has a stronger engine and - as the only Viggen - permanent shooting weapon. The only Viggen user is the Swedish military. Technical data (JA-37 version): length: 16.4 m, wingspan: 10.6 m, height: 5.9 m, maximum speed: 2230 km / h, climb speed: 203 m / s, practical ceiling: 18 800 m, maximum range: 2000 km, armament: fixed - 1 Oerlikon 30 mm cannon, suspended - up to 6000 kg of cargo.
