NASA’s New Radar-Equipped Gulfstream Aircraft is Set to Enhance Earth Science Capabilities | UAP

NASA’s latest aircraft may not be leaving Earth’s atmosphere, but the heavily modified Gulfstream IV twin jet will significantly enhance the agency’s data collection capabilities for Earth science missions.

Originally introduced in 1985, the Gulfstream IV (G-IV) is commonly used by the U.S. military and its allies for non-combat operations. Now, this aircraft is getting a second life as part of a scientific mission with NASA.

Taking inspiration from the National Oceanic and Atmospheric Administration (NOAA), NASA has outfitted the G-IV with advanced scientific instruments. The aircraft joined NASA’s fleet in February 2024, stationed at the Armstrong Flight Research Center in Edwards, California. While NASA is best known for space exploration, it is also deeply committed to Earth science, a focus the modified G-IV will support.

NASA’s test pilots have been flying the stock G-IV since June, collecting data on the jet’s handling and familiarizing themselves with its controls. These preliminary flights have established a baseline for the aircraft’s performance, and engineers are now working to install next-generation radar systems, with an expected completion date of October 11.

Once these modifications are complete, the G-IV will be able to carry a payload of up to 5,610 lbs. With a top airspeed of 459 knots and a maximum altitude of…
