NASA introduced the X-70 Fractal on Wednesday, the newest addition to its X-series of experimental aircraft and a crewed testbed intended to carry next-generation aviation technologies into real flight. The agency said the aircraft is expected to make its first flight under the NASA banner within the next two years. NASA Administrator Jared Isaacman framed the X-70 as one piece of what he described as a new beginning for aeronautics at the agency.
NASA is designing the X-70 as a high-performance, highly adaptable research platform, a role that puts it in the same experimental lineage as the Bell X-1, which first broke the sound barrier nearly 80 years ago, and the more recent X-59 quiet supersonic demonstrator. The agency has released only an AI-generated image of the aircraft, shown shrouded in smoke and shadows, but it confirmed several of the plane's specifications.
The X-70 will carry a crew and cruise at Mach .75, with a ceiling of 45,000 feet and an operational range exceeding about 1,726 miles. It will be able to accommodate up to 2,000 pounds of experimental equipment, mounted either inside or outside the aircraft. NASA also said the plane will feature advanced, rapidly reconfigurable flight-control technology that will let the agency study aircraft maneuverability in ways it says have never before been demonstrated in crewed flight.
According to Isaacman, the combination of a crewed, high-performance platform and a modular design is meant to keep NASA teams flying and learning while moving quickly from one experiment to the next. He said the ability to rapidly swap internal and external payloads is central to that goal, and that the aircraft will be used to test advanced flight-control, maneuverability and other cutting-edge technologies in real flight.
The X-70 is part of NASA's broader X-series program, which has served for decades as a proving ground for aviation research. The agency has not announced a specific date for the X-70's first flight beyond the two-year window, and the released image does not depict the aircraft in detail. For a US aerospace sector that relies on NASA testbeds to mature new flight technologies, the X-70 represents a new crewed platform for that work.
