Boeing has formally validated the stealth performance of its MQ-28 Ghost Bat following dedicated Radar Cross Section (RCS) testing, disclosed in an official release dated 29 May 2026. The campaign measured and confirmed the aircraft’s low‑observable characteristics against program objectives, providing customers with data on survivability in contested airspace.
The MQ-28 is an uncrewed collaborative combat aircraft designed to operate alongside existing military platforms, adding combat mass, persistence and enhanced survivability. Boeing positions the stealth validation as a key milestone in maturing the design for operations in highly contested environments where reduced detectability is central to mission planning and force structure decisions.
The RCS work follows a broader test effort that has already included extensive flight and digital trials, as well as separate international operational flights from Point Mugu in U.S. airspace. While Boeing has not released numerical RCS values or specific test conditions, the company states that the validated stealth performance is now part of the MQ-28 offering for current and prospective defence customers.
