Shield AI Unveils Full-Scale X-BAT VTOL Autonomous Fighter Drone Prototype

Shield AI has unveiled the first full-scale prototype of its X-BAT autonomous combat drone, a jet-powered aircraft designed to take off and land vertically on its tail. The rollout marks a critical hardware milestone for a system intended to operate without traditional runways or aircraft carrier decks.[1][3]

The prototype, designated X-BAT 001, is currently being transported from the company's manufacturing hub in Frisco, Texas, to a dedicated flight test facility in Newton, Kansas. The move initiates a rigorous ground and flight testing campaign aimed at proving the ambitious tail-sitting concept.[1][4]

"X-BAT 001 is a development aircraft, so the design will evolve as we test and refine it," a Shield AI spokesperson stated following the release of rollout footage. The aircraft features a swept, arrowhead-shaped wing profile and a prominent thrust-vectoring exhaust nozzle extending past the trailing edge.[1][3]

The drone's propulsion system relies on a GE Aerospace F110 engine paired with an Axisymmetric Vectoring Exhaust Nozzle, or AVEN. This specialized nozzle, originally developed in the 1990s for an experimental F-16 fighter, redirects engine thrust to provide pitch and yaw control during vertical flight.[1][5]

"That's a full-scale vehicle," Armor Harris, Senior Vice President and General Manager of Shield AI's aircraft division, said of the prototype. "It's got the outer mold line, it's got the F110 engine, the full propulsion path, everything in it."[1]

Runway Independence

The X-BAT is designed to launch and recover from a specialized trailer system, eliminating the need for heavy landing gear and reducing the aircraft's operational footprint. This approach allows the drone to be deployed from austere land bases or the decks of amphibious assault ships.[1][5]

"The launch and recovery vehicle is actually critical to the operation of the X-BAT weapon system because it enables survivability on the ground," Harris explained. "So when you're operating in a land-based environment, it enables basically shoot-and-scoot tactics."[1]

By operating from mobile trailers, the X-BAT aims to complicate adversary targeting in a manner similar to mobile missile launchers. On the maritime side, the system could significantly expand the U.S. Navy's strike capacity by turning expeditionary sea bases into ad-hoc drone carriers.[1][5]

The U.S. Navy is heavily backing the development through its Runway Independent Maritime Expeditionary Strike, or RIMES, program. Shield AI has received $200 million in Navy funding for the initiative, which the company has matched with an equal amount of internal capital.[1][5]

"The Department of the Navy Rapid Capabilities Office, in partnership with the Defense Innovation Unit, is aggressively accelerating development and testing of RIMES," a Navy spokesperson said. The goal is to deliver a long-range maritime strike capability to the fleet at the speed of relevance.[1]

Testing the Vertical Envelope

Before the X-BAT can conduct operational missions, Shield AI must prove that the heavy, jet-powered aircraft can safely transition between vertical hover and horizontal forward flight. Previous industry attempts to field tail-sitting jet fighters have historically struggled with this complex aerodynamic transition.[1][3]

The testing sequence in Kansas will begin with the aircraft positioned horizontally on its trailer to run the engine, before moving to vertical engine runs. The team will then suspend the drone from a massive crane to conduct tethered hover tests.[1]

"Then we have one of the biggest cranes in the world that's getting set up at our test site in Kansas right now, and we hang the vehicle suspended from that crane," Harris noted. Untethered free flights will only commence once the tethered testing validates the control software.[1]

The aircraft's flight control relies heavily on Shield AI's Hivemind autonomy software, which the company has previously refined on its smaller, propeller-driven V-BAT drone. The software must manage the thrust-vectoring nozzle and wing-mounted bleed-air thrusters to maintain stability during vertical maneuvers.[1][5]

Shield AI and GE Aerospace have already completed critical integration work on the propulsion system. In July 2026, the companies successfully conducted actuation and engine light-off testing at GE's facility in Peebles, Ohio, bringing the engine and nozzle together ahead of airframe installation.[3][5]

Scaling Combat Mass

The X-BAT represents a significantly larger and more capable platform than the initial drones being developed under the U.S. Air Force's Collaborative Combat Aircraft program. It is designed to carry internal munitions and a robust suite of sensors for multi-role missions.[1][3]

"Those multirole abilities put X-BAT in a very different category from Air Force Increment 1 CCAs," Harris stated. "X-BAT is twice the size, has the capacity for air-to-ground strike missions, and carries many more sensors on board."[1]

The integration of the F110 engine provides the X-BAT with a flight envelope that closely mirrors traditional crewed fighters. This performance allows the drone to keep pace with crewed aircraft during complex strike packages while carrying a heavier payload than smaller autonomous wingmen.[1][3]

The prototype revealed this week features a gray digital camouflage scheme and markings denoting the Hivemind software. While the current exhaust nozzle lacks low-observable treatments, Shield AI plans to refine the aircraft's stealth characteristics as the design matures toward production.[1][3]

The company has set an aggressive timeline for the program, aiming to fly a fully missionized version of the X-BAT by 2028. If development proceeds smoothly, Shield AI hopes to begin series production and achieve a limited operational capability by 2029.[1][5]

Strategic Implications

The push for runway-independent aviation reflects a broader shift in U.S. military strategy toward distributed operations. As adversaries field increasingly precise long-range missiles, traditional air bases and massive aircraft carriers are viewed as vulnerable fixed targets.[1][5]

AI

By distributing jet-powered strike capacity across smaller naval vessels and mobile ground units, the military can project power from unpredictable locations. The X-BAT's ability to operate without catapults or arresting gear makes it uniquely suited for this dispersed operational concept.[1][4]

The $400 million combined investment in the RIMES program underscores the Pentagon's urgency in fielding these capabilities. While the 2029 production target remains highly ambitious for a novel aircraft configuration, the rollout of a full-scale prototype demonstrates tangible momentum.[1][5]

As the X-BAT 001 prepares for its first engine runs in Kansas, the aviation industry will be watching closely. The upcoming vertical hover tests will serve as the ultimate validation of Shield AI's propulsion and autonomy integration.[1][3]

Success in Newton would not only advance the X-BAT program but also validate the viability of tail-sitting jet aircraft for modern combat. The transition from a bold concept to a flying prototype marks a pivotal moment in the evolution of autonomous military aviation.[1][4]

The U.S. Navy's interest in the platform extends beyond simple strike missions, as the service looks to integrate autonomous systems across its surface fleet. Deploying dozens of X-BATs across amphibious ships could effectively multiply the number of carrier air wings available to commanders in the Pacific.[1][5]

"So when you think about the number of carrier air wings that the Navy has to deploy, deploying X-BAT across all these other ships basically significantly increases the number of carrier air wings," Harris said. He noted this approach fundamentally changes the maritime deployment strategy.[1]

The X-BAT's operational future now hinges on its ability to execute complex aerodynamic transitions without constant human oversight. If Shield AI can meet its aggressive 2029 production target, the drone will fundamentally alter how the U.S. military projects air power from contested maritime environments.[1][4]
