Description

"The Saab 37 Viggen (English: "Tufted duck , ambiguous with ‌"Thunderbolt ") is a Swedish single-seat, single-engine, short-medium range combat aircraft, manufactured between 1970 and 1990. Several distinctive variants were produced to perform the roles of strike fighter (AJ37), aerial reconnaissance (SF 37), maritime surveillance (SH 37) and a two-seat trainer . In the late 1970s the all-weather fighter -interceptor JA 37 was added.

JA 37: Primarily a single-seat all-weather interceptor fighter, with a secondary attack role. First delivery in 1979, serial numbers 37301-37449. A 10 cm (4 in) stretch in the shape of a wedge wider at the bottom than on the top of AJ 37 fuselage between canard and main wing. PS 46A LD/SD radar. Partially decommissioned in 1998, some upgraded to JA 37D.

With the introduction of the JA 37 in 1979 came the Ericsson PS 46/A radar capable of guiding the two semi-active radar homing RB 71 missiles on the fuselage pylons simultaneously in combination with RB 24J / RB 24J air-to-air missiles. Unlike the strike variant a KCA 30mm Oerlikon internal cannon was carried as well as 126 rounds, in a conformal pod under the fuselage. The firing rate was selectable at 22 or 11 rounds. The KCA cannon fired 50% heavier shells at higher velocity than the older ADENs, giving a much higher kinetic energy.[24] This, in conjunction with the fire control system, allowed air-to-air engagements at longer range than other fighters.[25] The unguided cannon and rocket pods were available in the secondary ground-attack role.
The centerline pylon was almost exclusively carried a semi-permanent fuel tank, which was jettisonable in the event of a dogfight.
In 1987, the more advanced all-aspect RB 74 air-to-air missile was introduced for the JA 37. With the major upgrade of the JA to JA 37D in 1997 came the ability to carry four RB 99 on the fuselage- and inner wing pylons. In addition, a U95 ECM pod could now be carried under the right wing in place of an AMRAAM as well as chaff and flare dispensers on a pair of hitherto unused pylons just behind the main landing gear on each wing"
