Boeing MQ-28A Ghost Bat Block 3: Australia's Loyal Wingman with Internal Weapons Bay
The Boeing MQ-28A Ghost Bat is not merely a drone—it is Australia's declaration of aerospace independence. Developed by Boeing Australia in Queensland, the Ghost Bat is the first military combat aircraft designed, engineered, and manufactured in Australia in over 50 years. Now entering its most ambitious phase, the Block 3 upgrade introduces an internal weapons bay, 30% larger wingspan, and enhanced autonomous capabilities, transforming the loyal wingman into a true combat asset. With live-fire tests already conducted and the Royal Australian Air Force (RAAF) planning a fleet of over 20 units, the Ghost Bat has become the "poster child" of the AUKUS partnership. This is the engineering story of Australia's silent hunter.
1. What Is the MQ-28A Ghost Bat? Australia's Silent Hunter
- Name: MQ-28A Ghost Bat (named after the Australian carnivorous bat)
- Manufacturer: Boeing Australia — 100% designed and built in Queensland
- Type: Uncrewed combat aerial vehicle (UCAV) / loyal wingman drone
- Primary User: Royal Australian Air Force (RAAF)
- Block 1 status: 8 prototype units delivered (2021-2025)
- Block 2 status: 6 production units in final assembly; live-fire test completed (2026)
- Block 3 status: Under development — larger wingspan, internal weapons bay, enhanced AI
The Ghost Bat was unveiled in 2021 as a "loyal wingman" — an autonomous drone designed to fly alongside crewed fighters (F-35A, F/A-18F Super Hornet, EA-18G Growler) and perform reconnaissance, electronic warfare, or strike missions. Unlike conventional drones controlled remotely by a pilot on the ground, the Ghost Bat uses artificial intelligence to operate semi-autonomously, with a human "quarterback" issuing high-level commands rather than flying every maneuver. This reduces pilot workload and allows a single crewed aircraft to command multiple Ghost Bats simultaneously — turning one fighter into a squadron in effect.
"The Ghost Bat represents a generational leap in air combat capability," said a RAAF Air Vice-Marshal. "It is not a remote-controlled toy. It is an intelligent collaborator that can fly complex missions, share sensor data, and even engage targets — all with minimal human intervention. Block 3 will make it even more lethal and more independent."
2. 5 Fast Facts About the MQ-28A Ghost Bat Block 3
- 1. Internal Weapons Bay (First for Ghost Bat): Block 3 introduces an internal carriage system, allowing the Ghost Bat to carry missiles inside its fuselage — preserving stealth characteristics. The bay can accommodate one AIM-120 AMRAAM (air-to-air) or two GBU-39 SDBs (small diameter bombs). External hardpoints remain for additional ordnance.
- 2. 30% Larger Wingspan for Extended Range: Block 3 wingspan increases from approximately 6 meters to 7.3 meters. The larger wing carries 30% more fuel, significantly extending combat radius — crucial for operations across the vast Indo-Pacific region.
- 3. Live-Fire Test Success (2026): In a major milestone, a Block 2 Ghost Bat successfully launched an AIM-120 AMRAAM missile and destroyed an aerial target. The drone received targeting data from an E-7 Wedgetail airborne early warning aircraft, not from a ground pilot — demonstrating true autonomous kill chain integration.
- 4. Swarm Capability: The Ghost Bat is designed for manned-unmanned teaming (MUM-T). A single F-35A or Super Hornet can command up to four Ghost Bats simultaneously. The drones can perform reconnaissance, decoy, electronic attack, or strike missions — all while the pilot focuses on the primary threat.
- 5. Modular Nose for Mission Flexibility: Like earlier blocks, Block 3 retains the modular nose section, which can be swapped between missions to carry different sensor payloads: electro-optical/infrared (EO/IR) cameras for reconnaissance, electronic warfare suites, or radar systems. A single airframe can serve multiple roles in the same sortie.
"The live-fire test proved that Ghost Bat is not just a scout — it's a shooter," said a Boeing Australia executive. "Block 3 takes that further with internal carriage, so it can carry weapons without compromising its low-observable signature. This is a true combat drone."
3. MQ-28A Ghost Bat Performance Metrics
- Length: 11.7 meters (38.4 ft)
- Wingspan (Block 1/2): Approximately 6 meters (19.7 ft)
- Wingspan (Block 3): 7.3 meters (24 ft) — 30% increase
- Height: 2.5 meters (8.2 ft)
- Maximum Takeoff Weight (MTOW): Approximately 9,000 kg (19,800 lbs)
- Engine: Single turbofan (type classified, likely Pratt & Whitney or GE derivative)
- Maximum Speed: High subsonic (approximately Mach 0.85-0.92)
- Combat Range (Block 3): 3,700+ km (2,000+ nautical miles) — sufficient for trans-Pacific missions with refueling
- Service Ceiling: 45,000+ ft (13,700+ m)
- Endurance: 8-10 hours (mission dependent)
- Internal Weapons Bay (Block 3): 1x AIM-120 AMRAAM or 2x GBU-39 SDB
- External Hardpoints (Block 2/3): 4 under-wing stations for additional munitions or fuel tanks
- Sensor Payload (modular nose): EO/IR camera, electronic warfare suite, radar, signals intelligence
- AI Architecture: Autonomous mission management, with "human on the loop" supervision

- RAAF Planned Fleet: 20+ units (all blocks combined)
Analysis: The 3,700+ km range places the Ghost Bat in a unique class — longer-ranged than most loyal wingman drones (which typically operate within 1,500 km of their host). This allows RAAF fighters based in Darwin or Perth to project power deep into Southeast Asia, the South China Sea, and beyond without forward basing. The 30% fuel increase in Block 3 directly enables this extended reach. The internal weapons bay, while small (only one AMRAAM), is significant because it preserves the Ghost Bat's low-observable profile — something external carriage would compromise. For air-to-air missions, one missile per drone is sufficient if the drone operates as part of a swarm; four Ghost Bats could carry four AMRAAMs, effectively quadrupling the host fighter's magazine depth.
4. Engineering Insight: The Internal Weapons Bay Challenge
Adding an internal weapons bay to a drone the size of the Ghost Bat (11.7 meters long, roughly the same as an F-16) is a significant engineering challenge. The bay must be large enough to accommodate an AIM-120 AMRAAM (3.65 meters long, 178 mm diameter) or two GBU-39 SDBs (1.8 meters long), yet compact enough to not compromise the airframe's stealth shaping.
The Block 3 solution places the bay in the lower fuselage, between the engine inlet and main landing gear. Doors open only for weapon release, then close immediately to restore the low-observable surface. This is similar to the internal bay arrangement on the F-35 and F-22, but scaled down for a drone. Unlike crewed fighters, the Ghost Bat does not need to accommodate a pilot, so the bay can be positioned more centrally without cockpit constraints.
Why this matters: Without an internal bay, the Ghost Bat would be limited to external weapons carriage, which increases radar cross-section and reduces range due to drag. Block 3's internal bay allows the drone to penetrate defended airspace, engage targets, and return — all while maintaining a low-observable signature. For missions against advanced air defenses (S-400, S-500), this is a survival requirement.
"Internal carriage is a game-changer," said a Boeing Australia engineer. "You don't send a loyal wingman with external fuel tanks and missiles into a high-threat environment — it's just target practice. Block 3 gives the Ghost Bat the same stealthy weapon delivery as an F-35, at a fraction of the cost."
5. Manned-Unmanned Teaming: How Ghost Bat Fights
The Ghost Bat is designed for manned-unmanned teaming (MUM-T), where a crewed fighter (F-35A, Super Hornet, Growler) acts as the "quarterback" directing multiple drones. A single pilot can command up to four Ghost Bats, each performing different roles:
- Scout: Flies ahead of the fighter, using its sensors to detect enemy air defenses without risking the crewed jet.
- Decoy: Emits electronic signals to simulate a larger aircraft, drawing enemy fire away from the fighter.
- Electronic Attack: Jams enemy radar and communications, blinding air defenses.
- Strike: Launches weapons at pre-assigned targets, either autonomously or on command.
- Battlefield Manager: Relays real-time sensor data between distributed assets (ships, ground troops, other aircraft).
In the 2026 live-fire test, an E-7 Wedgetail — not a fighter — directed a Ghost Bat to engage an aerial target. This demonstrates that any aircraft equipped with the right data link can serve as the quarterback, not just fighters. In theory, a P-8 Poseidon maritime patrol aircraft could deploy Ghost Bats to hunt submarines or surface vessels, extending its reach far beyond its own sensors.
"The quarterback concept is revolutionary," said a RAAF officer. "One pilot, four Ghost Bats, and an AWACS means you have a miniature air force in a single formation. The Ghost Bats absorb the risk, and the human stays out of harm's way."
6. AUKUS and Export Potential: Ghost Bat Goes Global
The Ghost Bat is frequently cited as the "poster child" for AUKUS Pillar 2 — the technology-sharing agreement between Australia, the United Kingdom, and the United States. All three nations have expressed interest in acquiring or co-developing loyal wingman drones, and the Ghost Bat is the most mature platform in this category outside of classified US programs.
- United Kingdom: Considering Ghost Bat as a basis for its own "Mosquito" loyal wingman program; potential joint production.
- United States: USAF is evaluating Ghost Bat for the Next-Generation Air Dominance (NGAD) Collaborative Combat Aircraft (CCA) program. Boeing is offering a Ghost Bat derivative as a candidate.
- Japan: Expressed interest in acquiring Ghost Bats to accompany its F-35 fleet, as part of broader Japan-Australia defense cooperation.
- South Korea: Also considering loyal wingman drones; Ghost Bat is a potential off-the-shelf option.
- NATO allies: Several European nations (Poland, Germany) have expressed interest in loyal wingman technology; Ghost Bat could be exported to approved allies.
For Australia, exporting Ghost Bat would be a major defense industry achievement. Historically, Australia has imported nearly all its military aircraft (F-35, Super Hornet, P-8, E-7). Exporting a domestically-designed combat aircraft would reverse that trend and establish Australia as a credible defense exporter.
"Ghost Bat is not just for Australia," said a Boeing Australia executive. "We are already in discussions with multiple allied nations. The Block 3 upgrade with internal weapons bay makes it even more attractive to customers who need a stealthy strike drone."
7. Comparison: Ghost Bat vs Other Loyal Wingman Drones
Rather than a table, here is a qualitative comparison:
- vs Boeing Airpower Teaming System (ATS) — same platform: Ghost Bat is the Boeing ATS, just the Australian designation. The core design is identical, with Block 3 being the most advanced variant.
- vs General Atomics Gambit (USAF CCA): Gambit is a direct competitor, designed for the US Air Force's NGAD CCA program. Gambit is similar in size and concept but emphasizes modularity even more than Ghost Bat (entire wings can be swapped). Gambit is still in prototype phase; Ghost Bat is already operational.
- vs Kratos XQ-58 Valkyrie (USAF): Valkyrie is smaller (8.8 m wingspan), shorter range (~1,500 km), and has no internal weapons bay. Valkyrie has been flight-tested but not yet fielded in squadron strength. Ghost Bat is larger, longer-ranged, and more capable.
- vs Turkish Bayraktar KIZILELMA: KIZILELMA is a carrier-capable loyal wingman drone developed by Baykar. It is smaller than Ghost Bat, with shorter range, but is designed for operations from Turkey's LHD Anadolu (amphibious assault ship). Ghost Bat is not carrier-capable.
- vs Chinese GJ-11 Sharp Sword (drone-only): The GJ-11 is a stealth combat drone, but it is not primarily designed as a loyal wingman; it operates independently. China's loyal wingman program (the GJ-11 derivative or FH-97) is less mature than Ghost Bat.
Ghost Bat's key advantages: Operational maturity (Block 2 already in production), internal weapons bay (Block 3), exceptional range (3,700+ km), and AUKUS support for technology sharing.
8. Why This Matters for Australia and the Indo-Pacific
The Ghost Bat matters for three reasons. First, it represents Australia's emergence as a defense technology creator, not just a buyer. For decades, the RAAF relied on imported combat aircraft (F-111, F/A-18, F-35). The Ghost Bat is designed, engineered, and manufactured in Australia — creating high-tech jobs and a sovereign industrial base.
Second, the Ghost Bat is a force multiplier. A squadron of 12 F-35As equipped with 24 Ghost Bats effectively becomes 36 combat aircraft — but with only 12 pilots and 36 engines (4 per F-35). This dramatically increases combat power without increasing pilot training costs or base infrastructure.
Third, the Ghost Bat is designed for the Indo-Pacific. The 3,700+ km range allows RAAF fighters based in Darwin to reach the South China Sea without aerial refueling. Operating with Ghost Bats extends that reach even further, as the drones can perform forward reconnaissance or decoy missions while the crewed fighter loiters at a safe distance.
For Indonesia, which faces similar archipelagic challenges, the Ghost Bat offers lessons in how drones can extend the reach of a modest air force. While Jakarta cannot purchase the Ghost Bat (export restrictions likely apply), the concept of cheap, autonomous, and lethal drones should inform Indonesia's own defense planning.

Has the Ghost Bat been used in combat?
No. The Ghost Bat has been tested in live-fire exercises, including a successful AIM-120 AMRAAM launch in 2026. However, it has not yet been deployed in actual combat. RAAF expects to field the Block 2 fleet by 2027-2028.
How many Ghost Bats will Australia buy?
The RAAF plans to acquire over 20 Ghost Bats across all blocks. Block 1 (8 prototypes), Block 2 (6 production units, in final assembly), and Block 3 (additional orders expected as development completes).
Can the Ghost Bat operate independently?
The Ghost Bat is designed for manned-unmanned teaming (MUM-T). It can perform autonomous mission segments but is intended to operate under the supervision of a crewed fighter or AWACS aircraft. It cannot be deployed as a completely independent platform.
Who builds the Ghost Bat?
Boeing Australia, with facilities in Brisbane and Toowoomba, Queensland. The Ghost Bat is 100% designed and manufactured in Australia, though some components (engine, sensors) are sourced from international suppliers.
What is the range of the Ghost Bat Block 3?
The Block 3 Ghost Bat has a combat range exceeding 3,700 kilometers (2,000+ nautical miles) — sufficient to accompany RAAF fighters from Darwin to the South China Sea without aerial refueling.
How much does a Ghost Bat cost?
A Block 2 Ghost Bat costs approximately $25-30 million AUD (~$16-20 million USD). Block 3 may be slightly more expensive due to the internal weapons bay and larger wing. This is comparable to a fully armed fighter jet's cost per unit, but far cheaper than an F-35A ($120+ million AUD).
Can Indonesia buy the Ghost Bat?
Unlikely in the short term. The Ghost Bat is subject to AUKUS technology-sharing restrictions, and Australia is unlikely to export the platform to non-AUKUS nations until the RAAF has fielded its own fleet. However, Boeing may offer a downgraded export variant in the future, similar to the US practice with the F-35.
10. The Future of Ghost Bat and Australian Drones
The Ghost Bat is not the end of Australia's uncrewed combat aircraft ambitions — it is the beginning. Boeing Australia is already developing a "Ghost Bat 2.0" concept with increased internal payload, longer range, and optional carrier capability for RAN's future aircraft carriers. The company is also exploring air-launched effects (smaller, cheaper drones launched from the Ghost Bat itself).
For the RAAF, the Ghost Bat transforms how it fights. A fleet of 20 Ghost Bats, integrated with 72 F-35As, effectively creates a force of 92 combat aircraft — but with only 72 pilots. The drones absorb the risk, scout ahead, and engage targets, while the human pilots focus on command and control. This is the model for future air warfare.
For defense enthusiasts in Australia and the Indo-Pacific, the Ghost Bat is a source of national pride and a glimpse into the future of air combat. For Indonesia, it offers a case study in how a mid-sized power can develop autonomous systems to offset numerical disadvantages. And for the global drone industry, the Ghost Bat proves that loyal wingman technology has arrived — and Block 3 makes it lethal.
