First Air Group (Swedish: Första flygeskadern, E 1), previously named Air Group (Swedish: Flygeskadern) and later named Attack Group (Swedish: Attackeskadern) was an air group unit in the Swedish Air Force. The First Air Group was the collective name given to the attack wings who would jointly carry out heavier attacks in the event of war. It was active in various formations from 1938 to 1995. It was directly subordinate to the Supreme Commander of the Swedish Armed Forces and therefore nicknamed ÖB:s klubba ("Supreme Commander's club").
