Boeing has validated the stealth performance of its MQ-28 Ghost Bat collaborative combat aircraft, providing fresh evidence of the platform's survivability as air forces explore autonomous teaming concepts.

The milestone follows radar cross-section (RCS) testing designed to provide objective and repeatable data on detection risks and survivability, supporting procurement decisions, certification activity and operational planning.

The MQ-28 is designed to operate alongside crewed aircraft, carrying out missions including surveillance, electronic warfare and force multiplication while maintaining a low radar profile.

"The combination of a highly capable platform, stealth features, advanced autonomy and artificial intelligence provides unprecedented ability for air forces to extend their mission effectiveness and operational flexibility," says Brad Thompson, Director for Phantom Works Australia.

According to Boeing, the testing confirmed the effectiveness of the aircraft's design, production techniques and material selections in reducing radar detection. A lower radar signature decreases the range at which hostile systems can detect and engage the aircraft, improving survivability in contested environments.

The MQ-28 programme began in 2017 and the aircraft first flew in 2021. Since then, the platform has completed more than 150 flights and a series of demonstrations intended to mature collaborative combat operations.

Recent activities have included teaming two airborne MQ-28s and a digital aircraft with an E-7A Wedgetail, deploying to RAAF Base Tindal, progressing multi-aircraft teaming operations and conducting sustained daily flight testing.

The aircraft has also operated alongside an E-7A and an F/A-18F in a demonstration that autonomously engaged an airborne target, while international testing at Point Mugu in California validated autonomous operations and rapid deployment from an allied location.
