Boeing validates Ghost Bat stealth performance

Boeing has validated the stealth of its MQ-28A Ghost Bat in a series of Radar Cross Section (RCS) tests at an undisclosed measurement facility in the USA. This milestone further demonstrates the platform’s maturity, survivability, and ability to deliver cost-effective advanced capability for modern air combat operations, says Boeing in a media release.

The MQ-28A Ghost Bat is a Collaborative Combat Aircraft (CCA) designed to complement existing crewed aircraft by performing a variety of roles, including surveillance, electronic warfare, and force multiplication, all while maintaining a low radar profile. To this end it has a reduced RCS, though the company, DSTG and the RAAF have not provided details.

“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,” said Brad Thompson, Director for Phantom Works Australia.

The MQ-28A’s reduced RCS reduces the range that enemy radars can detect and engage it, enhancing the platform’s survivability in contested environments, says Boeing. The success of the RCS testing confirms the effectiveness of the MQ-28’s design, production and material choices in minimising radar detection, the company adds.

RCS testing was designed to provide operators with objective, repeatable data about survivability and detection risks. This information validates designs and models, supports procurement and certification, and guides tactics and countermeasure choices.

Development of the MQ-28A began in 2017, it made its maiden flight in 2021, and has completed more than 150 flights and several flight demonstrations including:

• Demonstrating interoperability by teaming two in-flight MQ-28As plus one digital aircraft with an airborne E-7A Wedgetail to complete a mission against an airborne target
• Deploying to an unfamiliar location – an operational RAAF Base at Tindal
• Progressing airborne teaming with multiple MQ-28 aircraft
• Conducting daily flight operations during test blocks
• Teaming with an E-7A and an F/A-18F to autonomously fire, and shoot down, an airborne target
• Logging its first three international operational flight tests in Point Mugu, California to validate autonomous operations, demonstrate rapid deployment and sustained operations from an allied location
