The images released from Exercise Valiant Shield 26 look spectacular on a corporate slide deck. High above the Philippine Sea, a U.S. Air Force F-15EX Eagle II flew in tight formation with a Boeing Defence Australia MQ-28 Ghost Bat drone. Pentagon public affairs offices immediately cataloged the moment as a historic milestone for human-machine teaming in the Indo-Pacific.
Do not believe the hype. Expanding on this idea, you can find more in: Japan's 38 Drone Killer Groupthink is a Multi Billion Dollar Mirage.
While the flight represents a genuine engineering step forward, the presentation of this event as a seamless evolution of ready-to-fight technology obscures a messy reality of defense procurement, industrial bottlenecks, and unresolved tactical dilemmas. The Air Force is practicing collaborative combat operations with an uncrewed aircraft it actively chose not to buy, controlled by a fighter jet whose integration software is still being written, all while staring down an adversary in Beijing that is expanding its own mass at a blistering pace.
The Drone the Pentagon Didn't Want
The MQ-28 Ghost Bat is a highly capable piece of hardware. Developed primarily by Boeing Australia for the Royal Australian Air Force, the 38-foot-long uncrewed platform boasts fighter-like performance, an adaptable mission nose, and a range exceeding 2,000 nautical miles. It is an ideal surrogate for testing the Collaborative Combat Aircraft (CCA) concept. Experts at Mashable have provided expertise on this matter.
However, a surrogate is all it will ever be for the United States.
In June, the U.S. Air Force explicitly bypassed the Ghost Bat for its highly anticipated CCA Increment 1 production contracts. The service instead awarded those contracts to General Atomics for the FQ-42A Dark Merlin and Anduril for the FQ-44A Fury. The Ghost Bat flying over the Pacific is a ghost in the procurement machine. It functions as a stand-in for the Nellis-based Experimental Operations Unit to gather data on how autonomous drones might behave in a theater before the actual operational fleet arrives.
This creates an awkward dynamic for Boeing. The aerospace giant has aggressively marketed the Ghost Bat to the Pentagon, utilizing concept art that routinely pairs the drone with the F-15EX. The Valiant Shield flight was as much a corporate marketing demonstration as it was a military exercise.
The Pentagon is using Boeing’s Australian-funded hardware to learn lessons that it will ultimately apply to aircraft built by Boeing's direct competitors. It is a pragmatically cynical move by the Air Force, but it underscores a deep fragmentation in allied drone development rather than a unified front.
The Backseat Bottleneck
Pacific Air Forces remained notably tight-lipped about the level of actual integration during the flight. When pressed on whether the F-15EX crew actively controlled the Ghost Bat or if the two platforms simply shared a highly coordinated flight path for the cameras, official spokespersons refused to comment on tactical details.
The hesitation highlights the unresolved core of the crewed-uncrewed teaming concept. Who actually flies the drone?
The F-15EX is unique among modern American fighters because of its two-seat configuration. The service has spent years debating what to do with the weapon systems officer (WSO) in the back seat. Optimists argue the WSO is the natural choice to act as an airborne battle manager, utilizing the massive cockpit displays to direct a swarm of loyal wingmen while the pilot focuses on flying and survival.
The physics and cognitive load of that division of labor remain highly theoretical. Managing sensors, parsing electronic warfare data, and executing weapons releases for your own aircraft is exhausting. Layering the command of three or four semi-autonomous uncrewed aircraft on top of that threatens to overwhelm human processing capacity, regardless of how customizable the cockpit screens are.
If the F-15EX was not actively passing dynamic mission commands to the Ghost Bat via an operational data link during the Valiant Shield flight, then the exercise was little more than a high-speed parade. The real challenge of CCA is not aerodynamic formation flight. It is the underlying software architecture that allows a human to command an autonomous system without looking at a joystick.
Supply Chain Realities and Broken Timelines
Even if the software were perfected tomorrow, the physical platforms are not arriving fast enough. The F-15EX involved in the Philippine Sea flight belongs to the 85th Test and Evaluation Squadron out of Eglin Air Force Base. It had to deploy to Kadena Air Base in Japan just to participate.
Permanent basing of the F-15EX at Kadena has slipped to 2027.
This delay is the direct result of industrial friction. A massive Boeing manufacturing strike that paralyzed production from August through November shattered delivery schedules. The Air Force desperately needs the F-15EX to replace aging F-15C/D models in the Pacific, yet the assembly lines cannot keep up with the strategic timeline.
The Air Force recently expanded its planned total buy of the Eagle II to 267 jets, signaling a renewed appreciation for the platform's massive weapons payload and range. The jet is envisioned as an airborne missile truck, lagging behind stealthy fifth-generation platforms like the F-35 to lob heavy ordnance at targets illuminated by forward sensors.
But a missile truck without missiles, or without the drones meant to scout ahead of it, is just an expensive target. The Ghost Bat itself is only moving into Block 2 production in Australia, with the fully operational Block 3 variant still deep in development. We are looking at a mismatched timeline where the controller aircraft are delayed by labor disputes, and the operational drones are still years away from mass production.
The Threat of Symmetric Autonomy
The rationale for the F-15EX and CCA pairing is simple geography. The Indo-Pacific theater is defined by vast, unforgiving distances. Traditional short-range fighters require an extensive network of vulnerable aerial tankers to reach the fight. The F-15EX and larger combat drones offer the structural legs required to operate across the first and second island chains.
The United States does not have a monopoly on this concept.

Western analysts frequently discuss how autonomous wingmen will complicate the battlespace for adversaries, generating what military planners call chaos and friction. They rarely acknowledge that the Chinese People’s Liberation Army Air Force is executing the exact same playbook. China is aggressively developing its own family of uncrewed effectors, designed to fly alongside heavy, non-stealthy fighters like the J-16.
When both sides deploy hundreds of semi-autonomous drones into the same airspace, the conflict ceases to be a clean demonstration of human-machine efficiency. It becomes an electronic warfare nightmare. The side that wins will not be the one with the sleekest airframe, but the one whose data links can withstand heavy jamming while maintaining the integrity of the autonomous loop.
Moving Beyond the Propaganda
If the Pentagon wants to turn the imagery from the Philippine Sea into an actual operational deterrent, it must stop treating these exercises as victory laps. The integration of the F-15EX and autonomous drones requires brutal honesty about what works and what does not.
The immediate next step requires testing the platform under severe electronic degradation. The Air Force must force its test units to attempt drone control while under simulated Chinese electronic attack, using the actual data link architectures planned for the FQ-42A and FQ-44A, rather than relying on clean commercial frequencies.
Furthermore, the industrial base must be stabilized. The vulnerability of American airpower to domestic labor strikes and supply chain bottlenecks undermines the entire concept of affordable mass. A drone that costs a fraction of a fighter jet is only affordable if you can build hundreds of them annually. Right now, the aerospace industry is struggling to deliver the crewed cockpits, let alone the uncrewed swarms.
The flight over the Philippine Sea proved that a fourth-generation fighter and an advanced drone can share a patch of sky without crashing into each other. That is an achievement worth noting. It is not, however, a strategy for winning a war in the Pacific. That strategy remains unwritten, waiting on software code and factory floors that are currently behind schedule.
