AJS37 Viggen is a Swedish cold war era strike aircraft designed by SAAB AB. It is a 90's modernization of the older 60's era jet AJ37 designed to give the aircraft enhanced capabilities in the reconnaissance (S) and strike (A) roles. AJ37 was Sweden's first attempt at a multi-role fighter and while it did not achieve true multi-role capabilities, it could still perform a variety of roles albeit with some limitations.

Because AJ37 did not achieve true multi-role capabilities, several variants of the Viggen were built, these are:

  • AJ37 - Regular Viggen, capable of strike and limited air to air but lacks reconnaissance capabilities.
  • SH37 - Spaningsviggen Hav (Recon Viggen Ocean), used for maritime patrol. It was equipped with a different radar (the PS 371/A) which had longer range than the PS 37/A used on the AJ37.
  • SF37 - Spaningsviggen Foto (Recon Viggen Photo), had a camera in the nose instead of a radar. It was used for optical reconnaissance.
  • SK37 - Skolviggen (School Viggen), used to train new pilots and was two-seated.
  • JA37 - Jaktviggen (Hunting Viggen), air to air viggen. Better radar, newer computer, and better air to air missile armament.
  • AJS37 - A 90's modernization of AJ37 with capabilities to carry newer weapon systems and reconnaissance equipment.


The variant of the Viggen we have in DCS is the AJS37 variant. This is one of the more modern Viggen variants and as a result can carry some relatively smart equipment, such as the BK90 and RB-15F. These were weapons originally intended for the JAS39 Gripen, but due to delays in the JAS39 program, the AJS37 was adapted to carry them as well. In order to carry said weapon systems, modifications to the CK37 flight computer, which was originally designed for the AJ37, needed to be made. The MPE (MultiProcessorEnhet) was added to the CK37 system to increase its computing power, and a data bus was added as well to support increased system communication. Another improvement for the AJS variant was the addition of the TERNAV navigation system. This system uses radar telemetry data and compare it to a prepared terrain map loaded from the AJS37 data cartridge in order to determine your location. The AJS37 saw service in the Swedish air force from 1991 to the early 2000's when the last planes were switched out for JAS39 Gripen.
