The United States has unveiled a full-size prototype of a vertical takeoff and landing (VTOL) combat drone, marking a significant step in its military aviation capabilities. This innovative development aims to integrate thrust vectoring technology with autonomous software, thereby reducing the dependency of jet drones on runways and large maritime platforms. The goal is to provide the U.S. Armed Forces with new, low-cost options for aerial strike capabilities in expeditionary operations.
On November 3, 2026, Shield AI, an American company specializing in artificial intelligence, showcased a video confirming the completion of its X-BAT vertical takeoff and landing autonomous combat drone prototype.
Just one day later, Armor Harris, the Vice President of Aircraft Engineering at Shield AI, announced that the prototype had been transported from the company’s research and development center in Frisco, Texas, to a flight testing facility in Newton, Kansas. There, it will undergo vertical takeoff and landing capability verification. The company plans to perform engine tests in both horizontal and vertical configurations, followed by tethered and untethered flight tests. The objective is to achieve mission-capable test flights by 2028 and commence mass production by 2029.
The X-BAT 001 prototype, depicted in the video, is the first of two full-scale test prototypes that Shield AI plans to manufacture. The drone utilizes a tailless and rear-stabilized vertical takeoff and landing design, powered by a General Electric F110-GE-129E engine. Notably, the axisymmetric vector thrust nozzle at the rear extends significantly beyond the trailing edge of the wings, showcasing a departure from earlier models that were embedded within the aircraft’s structure.
The overall aerodynamic layout is characterized by an arrow-shaped delta wing design. Since Shield AI first revealed the X-BAT concept in October 2025, the development team has made substantial improvements based on extensive high-speed and low-speed wind tunnel testing. This has optimized lift-to-drag ratios during high subsonic cruise phases, structural rigidity of the fuselage, and aerodynamic stability in high angle of attack scenarios, paving the way for the successful manufacturing and flight testing of the full-size prototype.
Moreover, the X-BAT prototype reflects advancements in stealth technology and manufacturing techniques. Its tailless configuration, sharply swept wings, and blended body design contribute to a favorable balance between aerodynamic efficiency and radar reflectivity. Adjustments to fuselage panel seams and the arrangement of thrust vector nozzles may also enhance its low-observable characteristics. The visible seams, fasteners, and openings on the prototype have ignited interest among observers regarding its stealth capabilities.
In an interview, Harris likened the differences between the X-BAT prototype and future production models to the relationship between the X-35 and F-35. He pointed out that this prototype is meant to complete flight validation using a conservative and reliable composite skin combined with a metal internal structure, setting the framework for weight reduction and stealth optimization in the production model.
However, it should be noted that Shield AI has yet to publicly disclose any data supporting the radar cross-section, infrared signature, or overall stealth performance of the drone.
The rear-stabilized vertical takeoff and landing design poses engineering challenges as well. The U.S. Air Force and Navy previously experimented with various turboprop and jet-powered rear-stabilized prototypes during the 1950s, but these early attempts did not lead to effective combat deployment. One of the main reasons for the failure of piloted rear-stabilized aircraft was that pilots faced severely limited visibility during vertical landings, making it difficult to accurately control thrust and attitude solely through manual operations.
The X-BAT, however, entirely removes the need for human pilots, combining its jet propulsion system with Shield AI’s advanced guidance and control algorithms. This allows the drone to autonomously correct its vertical takeoff and landing posture within a remarkably short time frame.
According to Harris, over the past year, Shield AI has conducted wind tunnel tests, engine trials, thermal assessments, and various other evaluations, effectively mitigating major risks associated with the project and fostering confidence for moving towards production design.
He explained that the testing team initially placed the X-BAT 001 in a horizontal position on a launch and recovery trailer to operate the engine, then transitioned the fuselage to a vertical position for engine operations. Subsequently, a massive crane at the Kansas testing facility lifted the aircraft to perform flight control tests while restrained. Following the successful completion of flight control verification, the crane will be removed to conduct real untethered vertical takeoff, landing, and transition to level flight trials.
The X-BAT’s autonomous combat capabilities stem from Shield AI’s Hivemind autonomous flight software, which has been validated on over 30 platforms since 2019.
Harris emphasized that with integrated sensors and navigational techniques, the X-BAT can autonomously complete the entire process from vertical launch, coordinated operations, target identification, to vertical recovery, even in environments where GPS signals are jammed and communication links are severed. In cases of offensive decision-making involving lethal strikes, the system adheres to the “in-the-loop” principle, requiring human commanders to issue engagement directives through a communication link.
In an official statement from October 2025, Shield AI positioned the X-BAT as a multirole autonomous tactical platform, designed for various missions including air-to-air strikes, ground attacks, electronic warfare, and intelligence, surveillance, and reconnaissance. The autonomous flight software allows it to act independently or in coordination with manned combat aircraft, using its vertical takeoff and landing design to operate from ships, islands, and remote locations lacking runways, thereby reducing dependence on traditional air force bases.
Benefiting from lightweight design principles and the rear-stabilized takeoff configuration, the X-BAT demonstrates tactical potential far surpassing that of similar drones.
According to data from Shield AI, the X-BAT has a length of approximately 9.75 meters, a height of about 1.52 meters, and a wingspan of roughly 11.9 meters. Its overall size is about one-third that of an F/A-18 Hornet fighter jet, yet it houses a high-thrust engine capable of delivering 29,000 pounds of thrust. The design notably omits cumbersome undercarriage structures typically found in conventional aircraft, such as the complex lift-fan systems in the F-35B, allowing it to achieve a thrust-to-weight ratio greater than 1 even when fully loaded with fuel and munitions. The X-BAT can vertically launch from a trailer without the need for rocket assist, subsequently transitioning into high-speed horizontal flight.
This combination of a high thrust-to-weight ratio and a favorable lift-to-drag ratio grants the X-BAT an operational altitude exceeding approximately 15,240 meters, a maneuverability overload capacity greater than 4 Gs, and a maximum range exceeding 3,700 kilometers with full weapons load, along with an operational radius surpassing 1,852 kilometers.
Additionally, its internal weapon bay can accommodate approximately 910 kilograms of munitions while maintaining a stealthy profile. It can carry up to two AGM-154 Joint Standoff Weapons or between six to eight medium-range air-to-air missiles. The drone can also be equipped with larger, external stand-off strike weapons under its wings, with the capability to adapt sensors and electronic warfare kits according to mission demands.
In comparison to the U.S. Air Force’s Phase One Collaborative Combat Aircraft (CCA), the X-BAT’s multipurpose capabilities distinguish it as a vastly different class of drone. The CCA concept envisions smaller drones primarily focused on air-to-air combat, while the X-BAT, being considerably larger, is capable of executing ground attack missions and carrying an array of additional sensors. Its larger thrust and thrust vectoring propulsion system endow the X-BAT with a broader flight envelope than those relatively smaller unmanned systems.
The rear-stabilized takeoff and landing design liberates the X-BAT from runway constraints and grants it a disruptive operational profile for both land-based and sea-based scenarios.
Harris noted that in numerous military simulations, it was found that the number of aircraft destroyed at ground bases by enemy long-range missiles and drones vastly outnumbered the losses incurred during aerial combat. He explained that mobile launch and recovery vehicles are challenging to detect, track, target, and destroy, providing critical ground survivability for the X-BAT weapon system, effectively enabling a “hit-and-run” tactical approach.
In the Pacific, launch trailers equipped with the X-BAT can be dispersed across remote islands and forward arming and refueling points, creating a decentralized fire network that is difficult for adversaries to incapacitate in one strike.
For maritime platforms, the X-BAT offers a pathway to augment naval air power projection without encroaching on carrier deck space.
According to estimates from Shield AI, three folded-wing X-BATs occupy deck space equivalent to that of one carrier-based fighter jet.
Deploying X-BATs on existing maritime platforms would significantly increase the size of the carrier air wing. This approach allows naval air power with a reach of 1,000 nautical miles to be spread across the entire surface fleet, reducing reliance on large carriers and consequently enhancing the survival and strike depth capabilities of the U.S. military in threatened maritime zones.
In addition to the X-BAT program from Shield AI, the U.S. Navy is running a parallel initiative known as the Runway Independent Maritime Expeditionary Strike (RIMES) program. This initiative aims to develop unmanned aerial systems that can operate from forward bases lacking robust infrastructure or vessels without extensive flight decks to conduct long-range maritime strike missions.
In 2026, the U.S. Navy allocated $50 million to Shield AI for the RIMES program, with the company providing an additional $50 million in matching funds. Furthermore, another $150 million investment from the Navy is directed towards the X-BAT program.
A Navy spokesperson stated that the service is accelerating development and testing of RIMES to coordinate the delivery of runway-independent long-range maritime strike capabilities to the fleet alongside the X-BAT.
Shield AI plans to initiate mass production in 2029, forming the initial combat capabilities of the X-BAT. This endeavor, which integrates thrust vector nozzles and artificial intelligence control systems into a rear-stabilized unmanned jet fighter, is a trailblazing process filled with engineering challenges and uncertainties.
The official debut of the X-BAT 001 prototype signifies a milestone in the evolution of “runway-independent heavy aerial strike capabilities,” promising to provide the U.S. military with novel unmanned aerial strike options in the Pacific expeditionary operations landscape.
