G-III in front of hangar The G-III/C-20A Research Testbed provides NASA, industry, and academia with a long-term capability for the efficient test of subsonic flight experiments and Airborne Earth Science endeavors.

The G-III/C-20A has been upgraded with basic research capabilities that can be customized to meet specific customer requirements.  The aircraft will provide a subsonic platform with the following performance capabilities:

Max Operating Altitude: 45000 ft
Max Mach: 0.85M
Max Endurance Cruise: 0.73-0.74M
Max Range Cruise: 0.75-0.76M
Range with full passengers: 3400 nm
Endurance: (.82M @ 37k) 5 hours (nominal), up to 7 hours
Max Ramp Weight: 70,200 lb
Max Zero Fuel: 46,000 lb
Max Takeoff: 69,700 lb
Max Landing: 58,500 lb
Max Fuel Capacity: 28,800 lb

The aircraft has been structurally modified to carry Earth Science instruments in the UAVSAR pod mounted to the belly of the fuselage. Additionally, the navigation system is being enhanced to support precision navigation for repeat pass Interferometry missions.
