The U.S. Marine Corps wants to field its first conventional takeoff and landing Collaborative Combat Aircraft (CCA) drones in 2029, and is also looking at the possibility of fielding similar drones with short takeoff and landing capabilities. The news comes soon after the service outlined its plans for Kratos’ XQ-58 Valkyrie, and potentially other CCAs, to be paired with its F-35s as a “bridge” to an entire family of next-generation air combat capabilities, which could include a sixth-generation crewed fighter. You can read more about the implications of that in our previous coverage.
Updates on the latest developments within the Marine Corps’ CCA program were provided by Col. Scott Shadforth, a program manager for the Expeditionary and Maritime Aviation Advanced Development Team (XMA-ADT), at the annual Modern Day Marine conference in Washington, D.C., at which TWZ is in attendance.
The Corps’ CCA efforts currently fall under a program called Marine Air-Ground Task Force (MAGTF) Uncrewed Expeditionary Tactical Aircraft (MUX TACAIR). The MAGTF is the primary organizing concept around which the service deploys air and ground forces.
Shadforth defines the CCA program as “how the Marine Corps is going after increasing the lethality of existing and future tactical aircraft in a high-threat environment.”
The MUX TACAIR effort emerged out of a previous effort that the Marine Corps War Fighting Lab sponsored as part of a Rapid Defense Experimentation Reserve (RDER) with the Office of the Secretary of Defense (OSD). This earlier program was known as the Penetrating Affordable Autonomous Collaborative Killer — Portfolio (PAACK-P).
The Marine Corps is kicking off its CCA efforts with a landing gear-equipped version of the XQ-58. In contrast, the previous PAACK-P program involved the rocket-assisted takeoff (RATO) variant of the XQ-58. Meanwhile, the MQ-58 designation refers to Marine-specific variants of Kratos’ Valkyrie now in development, although it remains unclear how official this is.
As Shadforth explained, under MUX TACAIR, the Marine Corps is attempting to answer the question: “How do we take that essential [XQ-58] airframe itself and turn it into a conventional takeoff and landing [CTOL] platform so that it’s reusable at a higher rate?”
The OSD effort involved four flights of the XQ-58, culminating in the fall of 2024. At the beginning of this month, the Marine Corps completed a risk-reduction flight involving XQ-58 payloads and integration at China Lake.
Up to this point, the tests have all involved RATO variants of the XQ-58, but the Marines are targeting a first flight using conventional takeoff and landing sometime in the mid- to late summer of this year.
Shadforth confirmed that the “ultimate goal” for the MQ-58 effort is to get its hands on “deliverable prototypes” in the summer of 2029. In an ideal case, he added, these would be delivered to VMX-1 in Yuma, “so the Marine Corps can actually get their hands on the aircraft and fly the aircraft in a tactical environment and develop the CONOPS for how they’re actually going to employ those.”
VMX-1, or Marine Operational Test and Evaluation Squadron One, has multiple aircraft types in its inventory and is responsible for tests and evaluations of all types of Marine aircraft and associated systems, while assisting in the creation of tactics, techniques, and procedures (TTPs).

MUX TACAIR doesn’t start and end with the MQ-58, however.
Shadforth said that the Marine Corps is currently exploring further MUX TACAIR options with “several vendors,” including General Atomics and Anduril. Meanwhile, the branch is also working with Northrop Grumman as part of the MQ-58 effort.
As to how the CTOL MQ-58 will be best integrated with the fleet of Marine Corps F-35Bs, which feature short takeoff and landing (STOVL) at the heart of their capabilities, this is something the service is still weighing up.
According to Shadforth, the Marine Corps “is always going to be interested” in finding ways for fixed-wing aircraft to operate from shorter runways, suggesting that a STOVL-type CCA could well be part of its future plans. Of course, a return to the RATO-capable MQ-58 could be one way of achieving this.
For now, the Marine CCA effort is squarely focused on the CTOL variant of the Valkyrie, but Shadforth said that it’s also looking toward the future, including “other vendor offerings, whether they exist in reality or not, that remove the need for landing gear.” CCAs that offer either runway independence or that are able to operate from shorter or improvised airstrips represent a capability “the Marine Corps will be interested in exploring,” Shadforth added. One obvious candidate here would be the X-BAT, the jet-powered autonomous stealth ‘fighter’ drone designed to take off vertically and land the same way, tail first, after completing its mission.
At this point, it should be recalled that Kratos said earlier this year that the CTOL version of the Valkyrie being developed for the Marines will still be able to make rocket-assisted takeoffs from static launchers. This means the drone will retain a valuable degree of runway independence, though it will have to touch down on a runway at the end of its sortie.
Before that, Kratos also unveiled a special launch trolley that allows variants of the XQ-58 without landing gear to take off from traditional runways, though not land back on them, as seen in the video below.

An aircraft with some kind of STOVL capabilities “just kind of opens up the world to us, where we don’t need 7,000-, 8,000-, 9,000-, or 10,000-foot paved runways. Those are always capabilities that we’re interested in,” Shadforth said.
Overall, this is a somewhat surprising route, considering that the XQ-58 in its basic form is already runway independent. This would suggest the Marines, in the future, are looking specifically for something that combines STOVL performance with faster sortie rates. After all, the XQ-58 also requires some infrastructure for that and requires a reset time. A STOVL or VTOL type of CCA would also be able to deploy and operate alongside the F-35B more seamlessly.
“As far as how CCA is envisioned integrating with existing STOVL-type platforms, the Marine Corps is kind of on the front end right now of getting CCA out to the operational forces. A lot of that’s going to come through experimentation and evaluation. As we target the 2029 timeframe to get prototypes out to VMX-1, part of their mission set is going to be: now we’ve physically got these things, how are we actually going to employ them with the various tactical aircraft we have available?” he continued.
As well as the STOVL F-35Bs, these tactical aircraft include CTOL/carrier-capable F-35Cs and potentially legacy F/A-18 Hornets, as well as other Joint Force capabilities.
Shadforth continued: “Those are issues that are going to have to be explored and experimented with for how we’re going to see how those CCAs are going to operate. The point being there’s no set solution at the moment.”
In terms of missions, the Marine Corps is initially focusing MUX TACAIR on an “electronic warfare type platform,” Shadforth said. “Those are the payloads we’re interested in looking at at the moment.”

But Shadforth confirmed that other efforts with different vendors are exploring how to use the space within the Valkyrie air vehicle to see what other payloads and capabilities are available to the Marine Corps. Not only usefulness but timeliness are important factors here, Shadforth added.
Kratos is known to be working on a miniature cruise missile called Ragnarok, which the XQ-58 can carry in its internal bay and externally under its wings, and you can read more about it here. Renderings have also shown Valkyries with AIM-120 Advanced Medium Range Air-to-Air Missiles (AMRAAM) under their wings. The drone can carry Small Diameter Bombs (SDB) internally, and has demonstrated drone launch — launched effects are therefore almost certain to be included for the electronic warfare mission.
Within all this, it is important to remember that, at this point, the Marine CCA effort is still very much in the prototyping phase, led by the MQ-58. As Shadforth noted, the service has “not entered into a specific acquisition-type construct yet,” beyond developing these prototypes. Nevertheless, with a timeline now in place to get the first MQ-58s to Yuma, and with conventional takeoff and landing trials expected in the next few months, MUX TACAIR reflects the overall acceleration of the Corps’ CCA program.
