The Boeing MQ-28A Ghost Bat is an Australian-developed unmanned combat aerial vehicle designed for autonomous operations alongside crewed aircraft, featuring a modular mission system and over 2,000 nautical miles range.
The Boeing MQ-28A Ghost Bat is an unmanned combat aerial vehicle (UCAV) developed by Boeing Australia for the Royal Australian Air Force (RAAF). Designed to operate autonomously or in conjunction with crewed aircraft, it serves as a force multiplier in various missions, including intelligence, surveillance, reconnaissance (ISR), and electronic warfare. The aircraft features a modular mission package system in its nose, allowing for rapid reconfiguration to meet diverse operational requirements. Measuring approximately 38 feet (11.7 meters) in length, the Ghost Bat boasts a range exceeding 2,000 nautical miles (3,700 kilometers), enabling extended missions over land and sea. Its design emphasizes stealth and versatility, incorporating advanced artificial intelligence to enhance mission effectiveness. The MQ-28A represents a significant advancement in autonomous aerial combat technology, reflecting a collaborative effort between Boeing and the Australian defense sector.
History of Development
In the late 2010s, the global defense landscape witnessed a growing emphasis on integrating unmanned systems into traditional military operations. Recognizing the potential of such systems to enhance air combat capabilities, the Royal Australian Air Force (RAAF) sought to develop an unmanned aerial vehicle that could operate seamlessly alongside its existing fleet of crewed aircraft. This initiative aimed to address emerging security challenges in the region and reduce reliance on foreign defense technology.
In 2017, Boeing Australia, in collaboration with the RAAF, launched the Airpower Teaming System (ATS) program. The objective was to create a low-cost, high-performance unmanned combat aerial vehicle capable of performing a variety of missions, including intelligence, surveillance, reconnaissance (ISR), and electronic warfare. The ATS was envisioned to act as a “loyal wingman,” supporting and protecting manned aircraft during operations.
The development process was marked by rapid prototyping and extensive use of digital engineering. A full-scale mock-up of the aircraft was unveiled at the Australian International Airshow in Avalon in February 2019, showcasing the design and intended capabilities of the platform. By May 2020, Boeing Australia had rolled out the first prototype, achieving significant milestones such as “weight on wheels” and “aircraft power on” in quick succession. Ground testing commenced in September 2020, focusing on engine runs and system functionality. The prototype underwent low-speed taxi tests in October 2020 and high-speed taxi tests by December of the same year. These rigorous testing phases culminated in the maiden flight on February 27, 2021, at the Woomera Range Complex in South Australia. During this flight, the aircraft followed a predetermined route, validating its flight control systems and performance parameters.
In March 2021, following the successful first flight, the Australian government increased its investment in the program, ordering additional prototypes to further the development and testing efforts. The aircraft was officially designated as the MQ-28A Ghost Bat during a ceremony at RAAF Base Amberley on March 21, 2022. The name “Ghost Bat” is derived from an Australian native mammal known for its collaborative hunting techniques, reflecting the aircraft’s intended role in team-based operations.
The MQ-28A represents a significant milestone as the first combat aircraft designed and developed in Australia in over half a century. Its development underscores the country’s commitment to advancing its indigenous defense capabilities and contributing to the broader objectives of allied forces. As of October 2024, eight prototype aircraft have been built, accumulating over 100 hours of flight testing. Operational tests have been conducted at the Woomera Range Complex, with sorties occurring regularly to validate various mission profiles and system functionalities. The program continues to evolve, with plans to integrate advanced mission systems and expand its operational envelope in the coming years.
Design
The MQ-28A Ghost Bat is engineered as a versatile and stealthy unmanned combat aerial vehicle, incorporating advanced technologies to fulfill a range of mission requirements. The aircraft measures approximately 38 feet (11.7 meters) in length, with a wingspan of about 24 feet (7.3 meters). Its design emphasizes a low radar cross-section, achieved through careful shaping of the fuselage and the use of composite materials. Notably, the aircraft’s wing is Boeing’s largest resin-infused single composite component, a technology derived from the Boeing 787’s wing development.
A distinctive feature of the MQ-28A is its modular mission package system located in the nose section. This design allows for the rapid swapping of payloads to suit various missions, including combat operations, force reconnaissance, and electronic warfare. The entire nose section can be removed and replaced with another equipped with the necessary sensors or equipment, enhancing the aircraft’s adaptability to different operational scenarios.
The propulsion system consists of a single commercial-off-the-shelf turbofan engine, speculated to be either the Pratt & Whitney Canada PW600 or the Williams FJ33, both known for their reliability and efficiency in light jet applications. This engine selection enables the Ghost Bat to achieve high subsonic speeds while maintaining fuel efficiency. The MQ-28A has a maximum range of over 2,000 nautical miles (3,700 kilometers), allowing it to operate independently or in coordination with manned aircraft over long distances. The aircraft is designed for both land-based and maritime operations, enhancing its strategic flexibility.
The Ghost Bat features a V-tail configuration, optimizing stability and aerodynamic efficiency. The side-mounted air intakes feed the single turbofan engine while minimizing the radar cross-section. The main wings have a sweptback leading edge and a compound trailing edge, enhancing lift and maneuverability. The aircraft is equipped with a tricycle landing gear, fully retractable to maintain aerodynamic efficiency during flight.
A key design feature is the aircraft’s Artificial Intelligence (AI) system, which enables autonomous operations and decision-making. This AI-driven system allows the Ghost Bat to function independently, execute coordinated strikes, conduct ISR missions, and react to dynamic battlefield conditions. The AI also supports real-time data fusion, enhancing situational awareness and decision-making capabilities.
While designed for low observability, the Ghost Bat is not a fully stealth aircraft. It prioritizes cost-effectiveness and operational flexibility over extreme stealth characteristics. However, its shaping and radar-absorbing materials reduce its detectability, making it a difficult target for enemy air defenses.
Performance
The MQ-28A Ghost Bat is powered by a single turbofan engine, designed to balance performance, efficiency, and cost. The exact engine model has not been disclosed, but it is estimated to provide a thrust output of approximately 3,000 to 5,000 pounds (13 to 22 kN). This allows the aircraft to achieve subsonic speeds of around 621 mph (1,000 km/h).
Key performance specifications:
- Maximum speed: ~621 mph (~1,000 km/h)
- Operational range: 2,000 nautical miles (3,700 km)
- Service ceiling: 40,000 feet (12,200 meters)
- Endurance: 4 to 6 hours, depending on mission load
Compared to other unmanned combat aerial vehicles (UCAVs), the Ghost Bat’s range and endurance place it among the most capable systems in its class. For reference:
- The Kratos XQ-58A Valkyrie has a range of 1,500 nautical miles (2,778 km) and a speed of 650 mph (1,046 km/h).
- The Dassault nEUROn has a range of 600 nautical miles (1,111 km) and a speed of 592 mph (953 km/h).
The Ghost Bat surpasses these competitors in range and modularity, making it more suitable for long-endurance operations and missions requiring payload flexibility. However, it is not designed for high-speed penetration missions like some stealth UCAVs.
