Boeing has validated the stealth performance of its MQ-28 Ghost Bat collaborative combat aircraft through radar testing in its own facilities, marking a key survivability milestone disclosed on 29 May 2026. The company used a dedicated radar test chamber to confirm the aircraft’s low‑observable characteristics, assessing radar detectability as part of a controlled campaign.
The MQ-28 is an uncrewed collaborative combat aircraft designed to team with crewed platforms in contested airspace, providing additional mass, persistence and survivability for advanced air combat operations. The stealth validation follows a progressive test and evaluation programme: by March 2025 the prototype fleet had accumulated more than 100 test flights and over 20,000 hours of digital testing, and by mid‑2025 Boeing and the Royal Australian Air Force had demonstrated operational viability in RAAF‑defined scenarios.
These incremental validations position MQ-28 as a candidate for future collaborative combat aircraft requirements, where low observability, autonomous operation and rapid deployability are emerging as core selection criteria for allied air forces.
