NASA’s X-59 research aircraft moves from its construction site to the flight line – or the space between the hangar and the runway – at Lockheed Martin Skunk Works in Palmdale, California, on June 16, 2023. This milestone kicks off a series of ground tests to ensure the X-59 is safe and ready to fly. The X-59 is designed to fly faster than Mach 1 while reducing the resulting sonic boom to a thump for people on the ground. NASA will evaluate this technology during flight tests as part of the agency’s Quesst mission, which helps enable commercial supersonic air travel over land.

NASA Life Support Technician Mathew Sechler provides support as the X-59’s ejection seat is installed into the aircraft at Lockheed Martin Skunk Works’ facilities in Palmdale, California. Completion of the seat’s installation marks an integration milestone for the aircraft as it prepares for final ground tests.

Ejection Seat Install

Lockheed Martin technicians temporarily remove the canopy from the X-59 in preparation for final installation of the ejection seat into the aircraft.

NASA’s X-59 quiet supersonic research aircraft moves under its own power for the first time at Lockheed Martin’s Skunk Works facility in Palmdale, California, on July 10, 2025. Guided by the aircraft’s crew chief, the event marks the beginning of taxi tests – a key milestone and the final series of ground tests before first flight.
