Himmelbue (Missile)

The Himmelbue is a medium range radar guided air-to-air and surface-to-air missile, derived from the Chezzetcooker R.5.25 for the Luftforsvaret and Kongelig Marine for use on their Nieuport-Saulnier Mystere Fighters, at the time Ringerike did not field a missile with a range anywhere near what the Himmelbue offered. It was first used in combat in the opening days of the Sorland War, when a Himmelbue-A launched by a J.71 Torden of the 16th Tactical Fighter Squadron downed a KNAF J-2.

In 2011 an updated model fitted with an AESA seeker was accepted into service. This seeker has since become the focal point of Ringeriker-Pojački co-operation on the R-90 Munja, to be accepted into service as the LvM.21.
