Boeing MQ-28 Ghost Bat Stealth Combat Drone Passes Key Radar Tests for Fighter Teaming.

Boeing’s MQ-28 collaborative combat aircraft has successfully validated its stealth performance through radar cross-section testing, reinforcing its potential value as a force multiplier for fifth-generation platforms such as the F-35 and future U.S. Air Force air combat operations. Announced by Boeing Defense on June 1, 2026, the results confirm a reduced radar signature that enhances survivability in contested airspace and supports the growing role of autonomous aircraft in penetrating advanced enemy air defense networks.

The testing demonstrates that the MQ-28 can combine low observability with autonomous mission capabilities, enabling it to conduct sensing, escort, and strike-support missions alongside crewed fighters while reducing pilot risk. As the U.S. Air Force advances its Collaborative Combat Aircraft (CCA) strategy, stealth-enabled systems like the MQ-28 highlight the shift toward human-machine teaming designed to extend combat reach, increase operational mass, and strengthen air superiority in future conflicts.

Radar cross-section testing measures how much radar energy an aircraft reflects and helps determine the range at which hostile radar systems can detect, identify, and engage it. For a collaborative combat aircraft expected to operate deep inside contested battlespaces, low observability is a decisive capability. Reduced radar detection enables autonomous aircraft to approach defended areas more closely, remain on station longer, and support crewed aircraft without exposing pilots to unnecessary risk.

The successful validation represents another significant milestone for the MQ-28 program, one of the most mature loyal-wingman and collaborative-combat aircraft initiatives currently in development. Developed by Boeing Defense Australia under the Airpower Teaming System program in partnership with the Royal Australian Air Force (RAAF), the MQ-28 was designed to operate alongside crewed fighters while extending their sensing, electronic warfare, and combat capabilities. The program marked the first military combat aircraft designed and manufactured in Australia in more than five decades and has attracted growing international attention as air forces seek autonomous force multipliers for future conflicts.

Since its first flight in 2021, the MQ-28 has progressed through an extensive testing campaign that has demonstrated autonomous flight operations, mission-system integration, teaming functions, and sensor capabilities. Boeing has steadily expanded the aircraft's operational envelope, transforming it from a technology demonstrator into an increasingly mature combat capability aligned with emerging concepts of manned-unmanned teaming.

Explore Boeing's MQ-28 Ghost Bat, the AI-powered stealth drone designed to fly alongside F-35 fighters as a loyal wingman. Learn how this Collaborative Combat Aircraft (CCA) combines autonomy, stealth technology, and advanced sensors to support future air superiority missions against modern threats from China and Russia.

The MQ-28 is a jet-powered autonomous combat aircraft measuring approximately 11.7 meters in length and featuring a combat radius suitable for long-range operations alongside modern fighter aircraft. Powered by a single turbofan engine and designed with a modular architecture, the aircraft can rapidly adapt to different missions through interchangeable payload sections. Its modular nose allows integration of intelligence, surveillance, and reconnaissance sensors, electronic warfare equipment, communications relay systems, and future mission-specific payloads. Advanced onboard autonomy enables the aircraft to perform assigned tasks with limited operator intervention while remaining integrated within a broader combat network.

One of the aircraft's most important characteristics is the combination of artificial intelligence-enabled autonomy and low-observable design. While traditional unmanned aerial vehicles often depend on continuous operator control, the MQ-28 is designed to execute missions independently, respond to dynamic battlefield conditions, and coordinate with crewed aircraft. This allows the aircraft to act as a true combat teammate rather than a remotely controlled asset, significantly reducing pilot workload while expanding operational flexibility.

The significance of the MQ-28 extends far beyond Australia. The aircraft represents one of the clearest examples of how future air warfare is evolving toward collaborative combat ecosystems in which autonomous aircraft operate alongside advanced fighters. For the U.S. Air Force, concepts demonstrated by the MQ-28 closely mirror objectives pursued through the Collaborative Combat Aircraft initiative, which seeks to field large numbers of autonomous aircraft capable of supporting F-35 Lightning II fighters and future NGAD aircraft during high-intensity operations.

Under the CCA concept, autonomous combat aircraft could perform missions that would otherwise place crewed fighters at greater risk. These include forward reconnaissance, electronic attack, suppression of enemy air defenses, communications relay operations, decoy missions, and weapons carriage. By distributing sensors and combat functions across multiple autonomous aircraft, commanders can increase combat mass and operational resilience while preserving high-value crewed assets.

Stealth plays a particularly important role in this concept. Modern integrated air defense systems increasingly combine active electronically scanned array radars, passive detection systems, long-range surface-to-air missiles, and advanced networking technologies, creating highly contested operational environments. Aircraft lacking low-observable characteristics face increasing challenges in penetrating such defenses. The MQ-28's validated stealth performance, therefore, addresses one of the most critical requirements for future collaborative combat aircraft expected to operate near or inside defended airspace.

A comparison of the Boeing MQ-28 Ghost Bat, China’s FH-97A, and Russia’s S-70 Okhotnik-B highlights how the United States and allied nations, China, and Russia are accelerating the development of AI-powered stealth combat drones designed to operate alongside crewed fighter aircraft in future air warfare.

The strategic relevance of such capabilities is becoming increasingly apparent in the Indo-Pacific region, where China continues to modernize both its air combat forces and integrated air defense networks. Beijing is actively developing autonomous combat aircraft concepts intended to complement advanced fighters such as the J-20 Mighty Dragon. Programs, including the FH-97A Loyal Wingman concept and other unmanned combat aircraft initiatives, demonstrate China's recognition that future air superiority will depend not only on advanced fighters but also on autonomous systems that extend combat reach, sensor coverage, and electronic warfare capabilities.

Russia has pursued a similar approach through the S-70 Okhotnik-B stealth combat drone program. Designed to operate alongside the Su-57 fighter, the Okhotnik combines low-observable shaping with strike and reconnaissance capabilities intended to enhance Russia's future air combat potential. While differing in design philosophy and operational concepts, both Chinese and Russian efforts underscore the growing global competition to field survivable autonomous combat aircraft capable of operating effectively in contested environments.

In this context, the MQ-28's latest testing milestone provides more than a technical validation of radar signature management. It demonstrates that one of the Western world's leading collaborative combat aircraft programs is making tangible progress toward delivering a survivable autonomous capability for future air operations. The aircraft's combination of stealth, autonomy, modular payload architecture, and networked operations aligns closely with the requirements increasingly identified by allied air forces preparing for potential conflicts against technologically advanced adversaries.

From an industrial perspective, the program also highlights Boeing's growing investment in autonomous combat aviation and its efforts to position the MQ-28 within the expanding global market for collaborative combat aircraft. As nations evaluate future force structures that combine crewed and uncrewed systems, proven survivability characteristics are likely to become a major differentiator in acquisition decisions.

The successful radar cross-section validation strengthens the MQ-28's position as one of the most advanced stealth drone programs currently available to allied nations. As military planners prepare for future conflicts characterized by dense sensor networks, long-range missile threats, electronic warfare, and increasingly capable adversary air forces, low-observable, AI-powered combat aircraft are expected to become essential elements of future air-superiority strategies.

For the United States and its allies, the MQ-28's latest achievement offers a glimpse into the future of air warfare. Whether operating as an F-35 wingman, supporting NGAD formations, conducting electronic warfare missions, or extending sensor coverage deep into contested territory, collaborative combat aircraft equipped with stealth and advanced autonomy could fundamentally transform how air power is generated and employed in the decades ahead. The validation of the MQ-28's low-observable performance, therefore, represents not only a milestone for Boeing's program but also a significant indicator of the direction in which future air combat is evolving.
