KF S.76 Valkrje

The KF S.76 Valkrje (Anglic: Vakyrie) is a single-seat, twin-engine aircraft in service with the Ringerike Royal Air Force, where it serves in the Attack, Anti-shipping, SEAD and Strike roles. The S.76 was borne of the desire for a dedicated attack aircraft suited for direct ground support and strike operations as well a limited air-to-air capability which would supplement the J.71 Torden which largely lacked such capabilities, with the Air Force viewing the S.65 Sjørover as widely unsuitable for their purposes, however later on they would acquire a number of them.

Development
The S.76's development shared a similar philosophy as that of the J.71 with both platforms sharing the ability to operate from dispersed airfields and converted roadways, with a particular focus on ease of maintenance, where the J.71 would be a capable Fighter-Interceptor and the S.76 focused on low-level strike in high risk environments. The process also leveraged several lessons learned from the J.71s troubled start to life, with the design going through much stricter oversight before leaving the paper phase.

F1 Upgrade Program
The F1 upgrade program introduced a number of improvements such as the ability to use a wider array of guided weapons systems such as the Dragefyr, greatly improving it's capabilities. It was also re-engined giving better performance, had it's avionics suite and improved and the cockpit was redesigned to integrate new systems interfaces.
