335 Squadron and 717 Squadron of the Royal Norwegian Air Force are stationed at Gardermoen, which operates respectively C-130J-30 Super Hercules transport aircraft and Dassault Falcon 20 electronic warfare aircraft.

The Norwegian Army started using Gardermoen as a camp already in 1740, when it was called Fredericksfeldt.

The airfield is built to easily expand cheaply and fast whenever needed.

On October 8, 1998 the main airport serving Oslo was moved from Fornebu to Gardermoen.

The Air Force was considering moving its operations at Gardermoen to Rygge Air Station by consent of the Chief of Defence of Norway, General Sigurd Frisvold in the 2003-2004 period; however, this proposition was turned down by the Norwegian Parliament's Defence Committee.
