Gulfstream III - LaRC

C-20B Gulfstream III

The NASA Langley Research Center received authorization from NASA Headquarters on September 18, 2017 to acquire three excess C-20B Gulfstream III aircraft from the U.S. Air Force. Two of these aircraft will be used as parts support for the Agency, and the third aircraft will be used for research. The research C-20B aircraft, designated NASA 520, will replace the Dassault HU-25A Guardian aircraft (NASA 524) as soon as practical. The research aircraft arrived at NASA Langley on December 7, 2017.  NASA Langley has awarded contracts to:  procure and install an engine hush kit; and, to design and install two nadir portals in the fuselage. The hush kit will enable the aircraft to be Stage III noise compliant, allowing the aircraft to deploy nationwide and worldwide without requiring engine noise waivers. The nadir portals will allow the aircraft to install earth science sensors, as is currently possible with the Center’s two King Air aircraft and the HU-25A aircraft. The goal is to have the C-20B aircraft ready for research at NASA Langley in April 2019.
