The AJS-37 Viggen is a Swedish double-delta supersonic attack aircraft from the late Cold War. It was the backbone of the Swedish Air Force during the Cold war, serving as the main attack and anti-ship platform. The AJS is the 90’s upgrade of this 70's era aircraft, adding several advanced weapons and systems functionalities. The aircraft was designed around the pilot, with an excellent man-machine interface, supporting the pilot through the smart use of autopilot systems, radar and HUD symbology in order to deliver the ordnance onto targets from treetop level with high speed attack runs.

The aircraft is armed with multiple weapon systems ranging from programmable stand-off weapons such as the RB-15F antiship missile to the BK90 Cluster munitions dispenser to various bombs, rockets and missiles for a wide range of target types. The aircraft can also carry gun pods and the Sidewinder series of infrared-guided missiles for air defence and self-protection purposes.
