exercise

U.S. Air Force Collaborative Combat Aircraft (CCA) are set to take part in a large-force employment (LFE) exercise for the first time later this year. Sending CCAs to the next iteration of the Emerald Flag test exercise is another important new stepping stone toward fielding the drones operationally.

“We have not yet done a LFE with these [CCAs], for real. The first one is going to be Emerald Flag. That’s in December,” Lt. Col. Lyndon “OTTO” Bartlett, Director of Operations for the Experimental Operations Unit (EOU) at Nellis Air Force Base in Nevada, said earlier today. “That’ll be our first tip dip of the toe in an actual force integration.”

Bartlett was speaking during a panel at the Air & Space Forces Association’s (AFA) 2026 Air, Space & Cyber Conference, at which TWZ is in attendance. The EOU has been leading Air Force efforts to lay the groundwork for future CCA operations. The unit has already been conducting various types of testing using prototypes of the General Atomics FQ-42A Vengeance and Anduril FQ-44 Fury. The Air Force announced in June that its initial operational CCA fleet would consist of a mix of FQ-42s and FQ-44s.

The Air Force’s 96th Test Wing at Eglin Air Force Base in Florida first began hosting Emerald Flag exercises in 2020. The exercise series has historically focused heavily on demonstrating new and improved aerial networking architectures and other command and control capabilities, which will be especially critical elements for future CCA operations. Emerald Flag, with its not purely limited to the air domain, is often tied in with other large force test exercise series. Other branches of the U.S. military regularly take part, as well.

It is worth noting here that Boeing’s MQ-28 Ghost Bat, a CCA-type design, did take part in Valiant Shield 26, another LFE exercise, earlier this year. The EOU was also involved. However, the MQ-28, originally developed for the Royal Australian Air Force, is not officially part of the Air Force’s CCA program at present.

Emerald Flag in December “will, in OTTO’s mind, be the first time that we will ever do some CCA end-to-end chain [demonstration] live. That’s the first time we’ll ever be integrated in a fourth- and fifth-gen combined OCA [offensive counter air] push,” Lt. Col. Bartlett added. “It’ll be small, but those type [sic] of building blocks are where I think you get the intangibles like trust in the CCA.”

“Those learnings are going to be just as valuable as the technical, [like] does the radio work properly? Does the button I push to say ‘target’ work properly?” he continued.

U.S. military officers, including tactical jet pilots, regularly talk about the critical need for trust in autonomous systems to perform as expected when directed in future operations. Establishing that trust, and doing so in real-world environments, is seen as foundational to answering larger outstanding questions about how CCA-type drones will be deployed, launched, recovered, supported, and otherwise operated, let alone employed tactically.

The EOU, together with other partners within the U.S. military and industry, have been working for years now to validate and improve autonomous capabilities in the virtual realm, and then test in more limited real-world contexts. Virtualized testing does offer immense benefits for rapid iterative development of the underlying software ahead of live demonstrations.

“If it’s in a simulated environment, it’s immediate,” Lt. Col. Bartlett said during the panel when asked about the “feedback loop” in testing the EOU is already taking part in. In that environment, “when the mission autonomy iterations are happening, our guys are literally with the programmers … They give the feedback, and if it’s possible to do immediately, they take that feedback. If not, then they work on it on the next turn of the software.”

Real-world testing, of course, offers opportunities to explore additional aspects of future CCA operations, including when it comes to loading weapons and maintenance. A key component of the Air Force’s vision for CCA employment is being able to forward deploy the drones to far-flung locations, including airstrips with limited infrastructure and access to logistics chains. Rapid, distributed deployments like this are central to still-evolving concepts of operations currently referred to collectively as Agile Combat Employment (ACE). The EOU has been involved in at least two rounds of ACE-focused testing this year, one at Edwards Air Force Base in California in April and another at Creech Air Force Base in Nevada in July. TWZ was the first to report on the latter event.

Visualizing ACE

During the panel today, Lt. Col. Bartlett also talked more generally about work EOU has done to date. This has included exploring “sortie generation, how easy they are to maintain, [and] how small a footprint could be.”

“We’ve been pleasantly surprised. The jets are extremely easy to maintain,” he continued. “We’re at a one-to-one maintainer-to-airplane ratio, which is crazy small.”

With “CCAs, [it] seems like because they’re a little bit simpler, because their role is so focused, what we found is that just about any – not just about, but we found that any AFSC [Air Force Specialty Code; alphanumeric codes used to identify specific jobs within this service] can be trained to generate sorties to load weapons, and we’ve done some of those things already,” he further explained. “It’s our job to bring them [CCAs] out and make sure that, beyond the technical specifications of it, that we’re kind of experimenting with the more complex things like logistics, and C2 [command and control], and how do we battle manage these things.”

The head of the EOU did acknowledge challenges that still have to be surmounted. This notably includes hurdles currently imposed by Federal Aviation Administration (FAA) regulations on the operation of fully uncrewed aircraft, even by the U.S. military, within U.S. airspace. This is further compounded by the explicit intention to operate CCAs with far more minimal human engagement compared to most existing drones.

“Mission autonomy is going to be the secret sauce that lets these things become decisive or not, and we’ll know that over the next couple years as that develops,” according to Bartlett. “If I were to identify the two biggest problems from the trenches of the EOU, [one] is FAA integration or policy implications to an autonomous airplane.”

“So these things don’t have pilots. They’re not RPAs [remotely-piloted aircraft]. They’re not manned fighters. They have no pilots,” he continued. “Our system is not set up for that, and that is a challenge that we are finding extremely hard to navigate through, and to not go around, but to make a policy.”

“We need to make sure the Air Force is ready for these things, to set policies that make sure the enterprise and the country is [sic] ready to receive these, and internalize an autonomous fighter that does not have a pilot that is running on a mission autonomy agent that doesn’t listen to ATC [air traffic control],” he added.

The second problem, per Bartlett, is making sure the Air Force develops new internal policies and doctrine that are not “copy and pastes from old regulations” that do not take into account the specific nuances that CCAs will bring. What the service needs is “something that enables us to move quickly with these things, to weigh what we need, and to experiment with novel types of air superiority.”

All of this circles back to the discussion of trust in autonomous capabilities. It also speaks to the potential for future operations where CCAs could operate far more independently.

“It’s in the name that they’re collaborative,” Bartlett said. “Taking them out of that could technically be effective, but would not enhance the joint force the way that we see a collaborative, integrated force package to be.”

“What we need autonomously to do is written down. I won’t discuss the particulars in this forum, but we know what we need it to do, or we know what we think it really needs to do,” he noted. “We’ve structured our experimentation game plan to analyze ‘can it do those things?,’ and if not, then how do they need to be different? And then as they iterate on it, which we’ve already seen a couple times, we get that at the EOU, we get the new version down, we fly it again. Is it fixed? Yes or no.”

Some members of industry are clearly envisioning futures with different definitions of ‘collaborative’ that could lean more toward independent operations involving highly autonomous drones.

What “the whole entire program is trying to do is [figure out] what is the requirement to put out into the field to get to the warfighter and to start operating this thing this [sic; in] real time?” Robert “Otis” Winkler, Vice President of Corporate Development & National Security Programs at dronemaker Kratos, another one of the panelists, said. “The collaborative part of this makes it a much easier, I think, technical problem to be able to limit and grow the autonomy as you field this.”

“I think eventually we may see these aircraft utilized as collaborative aircraft, but not in conjunction with your traditional pulsed operation, but in support of that pulsed operation when the pulse isn’t there yet. But I do think that that is a bit of a stretch goal that’s going to be down the road.”

CCAs “have been designed really around increasing both survivability and lethality of current force packages. So there are many manned platforms that you would describe in the exact same fashion,” Jason Levin, Senior Vice President for Air Dominance and Strike at Anduril, who was also on the panel, said. He was responding here to a specific question about whether his use of the term “fighter” to describe these drones implied more emphasis on independent operations.

All of this underscores the importance of bringing CCAs to Emerald Flag in December, as well as other events in the future offering opportunities to see how the drones really fit in with other crewed platforms. The Air Force is hoping to start seeing CCAs enter operational service around the end of the decade, and have 500 of them, at least, in inventory by 2032.

During the panel today, the EOU’s Lt. Col. Bartlett made clear that “we’re going to learn a lot over the next couple years.”
