F-15EX Eagle II: Flying with CCA Drone in Pacific for Future Air Combat
The image looked like something out of a science fiction film: a cutting-edge F-15EX Eagle II fighter jet cruising over the Philippine Sea alongside an autonomous uncrewed aircraft, no second pilot required. Yet this wasn’t Hollywood — it was Exercise Valiant Shield 2026, and it may well represent one of the most consequential moments in modern aerial warfare history.
This demonstration of the F-15EX Eagle II flying with a Collaborative Combat Aircraft drone in the Pacific isn’t just a headline-grabbing stunt. It’s a deliberate, strategic signal that the U.S. Air Force is actively reshaping how it will fight — and win — in future conflicts, particularly in the vast, contested airspace of the Indo-Pacific region. The pairing of a battle-proven manned fighter with an autonomous AI-driven drone represents a fundamental shift in air combat doctrine.
What makes this event even more fascinating is the specific drone involved: the MQ-28 Ghost Bat, an Australian-developed platform that the USAF hasn’t officially purchased for its main Collaborative Combat Aircraft program. That detail alone raises compelling questions about where military aviation is headed — and how fast it’s getting there.
The Valiant Shield 2026 Demonstration: What Happened Over the Philippine Sea
Exercise Valiant Shield 2026 brought together an F-15EX Eagle II and an MQ-28 Ghost Bat for a landmark demonstration of human-machine teaming (HMT) over the Philippine Sea. The exercise, one of the largest and most complex U.S. military exercises in the Pacific, provided an operationally realistic environment to test this emerging concept of manned-unmanned teaming (MUM-T).
The goal wasn’t to perform aerial acrobatics. The mission was fundamentally about proving that a fighter pilot can effectively command, coordinate, and leverage an autonomous uncrewed aircraft as a wingman — extending the pilot’s senses, reach, and firepower without requiring another human in a cockpit.
Why the Pacific?
The Indo-Pacific theater is not a random backdrop for this test. It’s the most strategically relevant environment imaginable. Enormous operational distances, contested maritime zones, and the looming challenge of adversary air defense networks make the Pacific the proving ground for next-generation air combat concepts.
Any future conflict in the region would demand that the USAF project power across hundreds or thousands of miles of open ocean, often without the luxury of nearby air bases. Drones that can extend a fighter’s reach, absorb risk, and operate semi-autonomously in degraded environments are not optional extras in this context — they are strategic necessities.
The F-15EX Eagle II: A 4th-Gen Fighter Gets a New Mission
The F-15EX Eagle II is the most advanced variant of the F-15 family ever built. Boeing’s latest iteration carries an open mission systems architecture, massively upgraded computing power, and the ability to carry more weapons than any fighter jet in U.S. history — up to 22 air-to-air missiles in certain configurations.
But in this new role, raw firepower takes a back seat to something equally important: command and control.
Why the F-15EX Is Built for the “Mothership” Role
The F-15EX’s open architecture is the key enabler here. Unlike older fighters locked into fixed software, the Eagle II can rapidly integrate new systems, software updates, and communication protocols — exactly what’s needed to interface with autonomous uncrewed platforms.
Several factors make the F-15EX particularly well-suited as a CCA controller:
– Processing Power: The Eagle II’s advanced computing systems can handle the massive data streams generated by coordinating multiple uncrewed aircraft simultaneously.
– Power Generation: The aircraft generates enough onboard electrical power to support advanced sensor fusion and communication arrays required for drone teaming.
– Range and Payload: With its exceptional range and payload capacity, the F-15EX can carry additional datalink pods or communication systems without sacrificing core combat capability.
– Cost Economics: Compared to 5th-generation fighters like the F-35 or the forthcoming Next-Generation Air Dominance (NGAD) platform, the F-15EX offers a more cost-effective “quarterback” for CCA operations, preserving the stealth assets for the most penetrating missions.
The choice to use a 4th-generation-plus fighter rather than a 5th-generation aircraft for this demonstration is deliberate. The USAF needs CCA integration across its entire fleet, not just its most advanced platforms, and the F-15EX represents the bulk of future tactical fighter acquisitions in the near term.
The MQ-28 Ghost Bat: Australia’s AI Wingman Takes Center Stage
The star of the show alongside the Eagle II is the MQ-28 Ghost Bat, originally developed under Boeing Australia’s Loyal Wingman program. Designed from the ground up for collaborative combat operations, the Ghost Bat was built to fly alongside manned aircraft and execute missions that are either too dangerous, too distant, or too numerous for human pilots to handle alone.
Ghost Bat Specifications and Capabilities
The MQ-28 is a striking aircraft. With a length of approximately 11.7 meters and a stealthy aerodynamic profile, it’s designed to reduce radar cross-section while maintaining the agility needed for tactical operations. Its modular nose section allows mission payloads to be swapped depending on the tasking:
– Intelligence, Surveillance, and Reconnaissance (ISR): Persistent sensor coverage in contested airspace where sending a manned aircraft would be excessively risky.
– Electronic Warfare (EW): Jamming and suppressing enemy radar and communications systems ahead of a strike package.
– Strike Missions: Carrying weapons to extend a formation’s offensive reach.
– Decoy Operations: Drawing enemy fire and depleting adversary missile inventories before manned aircraft enter the threat envelope.
The Ghost Bat’s AI-driven autonomy allows it to execute complex tasks with minimal real-time input from its human controller. It can navigate, respond to threats, and adapt its flight path while keeping the human pilot in the decision loop for critical actions.
The Drone the USAF Didn’t Buy — and Why That Matters
Here’s where things get strategically interesting. The USAF has selected five companies to develop competing CCA designs under its official program. The MQ-28 Ghost Bat is not among them. So why is the Air Force flying it over the Philippine Sea in a major exercise?
The answer reveals a great deal about how the USAF is approaching CCA development. Rather than waiting for a single officially-procured platform, the service is using the Ghost Bat as an exploratory test asset — a way to rapidly develop tactics, techniques, and procedures (TTPs) for human-machine teaming without being constrained to one design philosophy.
This approach also deepens the U.S.-Australia defense relationship. Under the AUKUS security partnership, interoperability between allied platforms is increasingly critical. Testing the Ghost Bat in the Pacific isn’t just about the drone — it’s about demonstrating that allied uncrewed systems can integrate seamlessly with U.S. Air Force operations.
The USAF’s Broader CCA Program: Building an Affordable Arsenal
The F-15EX/Ghost Bat demonstration doesn’t exist in isolation. It’s one data point in a much larger transformation underway across the U.S. Air Force’s Collaborative Combat Aircraft program.
The USAF’s stated ambition is audacious: field thousands of affordable, attritable uncrewed aircraft to augment manned platforms. The word “attritable” is important — these are drones designed to be affordable enough that losing one in combat doesn’t represent a catastrophic financial or strategic loss. Unlike a $100 million fighter, an attritable CCA can absorb risk, enter heavily defended airspace, and if necessary, be expended without sacrificing a human pilot.
Key Programs Shaping the CCA Ecosystem
Several interrelated programs are accelerating the CCA vision:
Skyborg: The USAF’s AI-driven autonomy program that develops the software “brain” for uncrewed platforms. Skyborg is about creating a common autonomy core that can be applied across different drone airframes, enabling them to fly, navigate, and make tactical decisions with varying levels of human oversight.
Project Venom: A rapid prototyping and experimentation effort specifically focused on accelerating software and technology integration into autonomous systems. Project Venom is designed to compress development timelines dramatically — getting new capabilities from concept to operational testing in months rather than years.
Next-Generation Air Dominance (NGAD): The USAF’s most advanced future combat aircraft program, NGAD envisions a “system of systems” where a crewed 6th-generation fighter operates alongside multiple CCAs. The manned aircraft becomes a quarterback, while drones extend its eyes, ears, and weapons reach far beyond what a single pilot could achieve.
The F-15EX/Ghost Bat pairing tested at Valiant Shield 2026 is essentially a near-term, real-world prototype of what the NGAD concept will eventually look like at operational scale.
What Human-Machine Teaming Actually Means in Combat
The phrase “human-machine teaming” gets used frequently, but its practical implications in aerial combat are worth unpacking carefully.
In a traditional two-ship fighter formation, both pilots communicate in real time, make split-second decisions independently, and back each other up instinctively. Replacing one of those aircraft with an autonomous drone fundamentally changes the dynamic. The human pilot must now manage their own aircraft, fly tactically, and simultaneously direct the drone’s actions through digital commands — all under the extreme cognitive load of combat.
The Control Interface Challenge
The F-15EX’s advanced cockpit displays allow the pilot to monitor the CCA’s status, assign waypoints or targets, and authorize or override autonomous decisions. But the interface must be intuitive enough to use under stress, with gloves on, pulling G-forces. Getting that human-machine interface right is one of the most technically demanding aspects of the entire program.
Critically, the level of autonomy given to the drone is a sliding scale. In permissive airspace, the CCA might execute complex multi-waypoint ISR missions with minimal input. In the merge — the close-quarters chaos of a dogfight — the human remains firmly in control of lethal decisions.
Ethical Considerations of Autonomous Combat Aircraft
The integration of AI-driven autonomous systems into combat raises legitimate ethical questions. Military doctrine and international law require that human beings retain meaningful control over life-and-death decisions on the battlefield. The USAF’s approach to CCAs maintains this principle by keeping humans “in the loop” for weapons release, even as the drone handles navigation, sensor management, and threat avoidance autonomously.
This isn’t just a legal or ethical checkbox — it’s an operational requirement. Trust between pilot and machine must be earned through demonstrated reliability before autonomous systems can be granted greater operational latitude.
Challenges on the Road to Operational Reality
Despite the progress demonstrated at Valiant Shield 2026, significant challenges remain before CCA teaming becomes routine in operational squadrons.
Communications Reliability: The datalink connecting the F-15EX to its CCA drone must remain robust in environments where adversaries actively jam or spoof communications. Developing resilient, low-probability-of-intercept communications is a major ongoing technical challenge.
AI Reliability and Trust: Pilots need to trust that the drone will do what it’s told and not misinterpret ambiguous situations. Building that trust requires thousands of hours of testing across the full spectrum of combat scenarios.
Training and Doctrine: Fighter pilot training must evolve to incorporate CCA management. The skills required to effectively quarterback a drone while simultaneously flying a tactical mission are genuinely different from traditional fighter pilot skills — and developing the curriculum to teach them takes time.
Budgetary Reality: Fielding thousands of CCAs at acceptable unit costs requires a procurement approach the defense industry has rarely been asked to execute. Keeping costs low enough to make CCAs truly “attritable” while maintaining the capability to be tactically meaningful is an ongoing tension.
