Gardermoen Air Station (Norwegian: Gardermoen flystasjon) is located about 50 km north of Oslo, Norway. It is the location for the 135th Airwing and the 335th Sqadron of the Royal Norwegian Air Force, who operate six C-130 Hercules transport aircraft. In addition the airfield is designed to handle the complex logistics of the air force, and is one of the most advanced C-130 installations in Europe. Norway's main airport, Oslo Airport, Gardermoen is located at the air station.
The Air Force is considering moving its operations at Gardermoen to Rygge Air Station.
During the German invasion of Norway during World War II the German bombed the airport, but built it up with two 2000-meter runways during the war.
The military airport was founded on December 1, 1996, with new installations for 1,2 billion NOK. 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 new airport had among other facilities two runways.
