was able to preserve the lineage of these two distinguished units. The U.S. part of Soesterberg was returned to the Netherlands government on 27 September 1994. Only one USAF F-15A remains in the Netherlands, and is displayed at the Military Aviation Museum. Soesterberg then became a Royal Netherlands Air Force transport helicopter base with 298th squadron (CH-47 Chinook) and 300th squadron (AS 532 U2 Cougar and SA 316) stationed at the base. Flying officially ended on 12 November 2008. The last jet ever to take off was a Hellenic AF F-4E Phantom II. The base formally closed on 31 December 2008, with the 298th and 300th Squadrons of the Royal Netherlands Air Force moving to Gilze-Rijen Air Base. However, a part of the base remains in use as a glider field. The former USAFE side remains in use by Dutch military ground units and is called "Camp New Amsterdam". The Nationaal Militair Museum opened at the former base in 2014 and utilizes most of the existing hangars. In 2018, Utrechts Landschap (a private heritage protection organisation) purchased the former airbase land (comprising 400 hectares) and is currently maintaining protection of both the natural landscape (including habitats of rare and newly discovered insect species) and military remains.
