The proliferation of drones in land warfare has brought maneuver to a stalemate, extracting a significant toll in terms of both man and machine. Attack helicopters and their crews, long the lifeblood of maneuver warfare, are increasingly held at risk by a combination of loitering munitions, cheap air defenses, and ubiquitous persistent ISR platforms that have rendered the near-surface domain one of the most lethal places on the battlefield.
In this robotic kill zone, maneuver warfare hinges on the ability to exploit an adversary’s weaknesses through principles like speed, agility, reach, and decisive mass. Any one of these attributes on their own is insufficient. Instead, it is the combination and orchestration of these elements that unlocks the decisive blows that enable friendly forces to maneuver to a position of advantage. All of these dynamics point to a new reality for maneuver warfare: one that must be driven by autonomous technology in attack aviation.
Today, Anduril is unveiling its answer to these changing conditions: Thunder, a Group 5 autonomous attack rotorcraft specifically designed to multiply the combat power and increase the survivability of current and next-generation crewed attack and assault aircraft. Thunder is equipped with the payload capacity and open architecture required to deliver overwhelming effects for any mission, engineered with the survivability, speed and range critical for the deep fight, and built on flight-proven autonomy that enables validated, high-performance teaming with crewed assets.
Reach Farther, Faster
Thunder is purpose-built for the new geometry of battlefield maneuver, wherein long-range fires, contested staging areas, and vast theaters all push attack aviation farther from the fight. Thunder’s tiltrotor configuration combines vertical takeoff and landing (VTOL) with efficient wingborne cruise, enabling runway-independent operations from austere locations without the range constraints of traditional rotorcraft.
Thunder is the defense-specific variant of a dual-use platform co-developed with Archer Aviation, bringing the commercial VTOL sector's rapid innovation in electric propulsion and rotor design directly into defense. A series hybrid-electric powertrain enables Thunder to achieve significant range and endurance, while still maintaining the necessary precision to closely optimize power through the full range of flight conditions. Meanwhile, Optimum-Speed Tiltrotors (OSTR) vary rotor RPM to maintain efficiency across flight regimes, reducing power demand and fuel burn in cruise and minimizing acoustic signature to enhance survivability during low-altitude ingress.
The tiltrotor configuration, series hybrid-electric powertrain, and rotor technology provides Thunder with the range necessary to support global self-deployment. Alternatively, Thunder can be packed into a standard shipping container for transport by air, road, rail, or sea, offering the multi-modal transport logistics required to reach any fight.
Designed to Deliver Mass
Anduril has configured Thunder to bring affordable mass to the deepest, most heavily-defended parts of the battlefield. Whether the aircraft is needed as a missile carrier, air-launched effects mothership, maritime patrol aircraft, or contested logistics platform, Thunder offers the payload capacity and flexibility required to overwhelm sophisticated defenses and finish the mission.
Modular internal main and nose payload module bays enable Thunder to host lethal combinations of precision munitions, air-launched effects, rockets, electronic warfare payloads, counter-UAS force protection, and cargo, and is provisioned for rapid integration of future mission systems. For example, Thunder’s main payload module can be configured with ten air-to-ground missiles (e.g. Hellfire, JAGM, Barracuda-100M), sixteen launched effects (e.g. Altius-600), or seventy-six 70mm rockets, plus an additional twelve counter-UAS effectors, in the nose payload module, providing a mix of effects to address a wide variety of threats during a single sortie.
Teaming multiplies the mass that Thunder brings to the fight. By pairing multiple Thunder aircraft with a single crewed platform, commanders can achieve a step-change in combat mass that enables formations to defeat more targets, sustain operations longer, and keep crews farther from the most lethal threats. By teaming three Thunder aircraft with each Apache, for example, a Combat Aviation Brigade will achieve a 3x increase in available munitions without placing additional pilots in harm’s way, all at a fraction of the cost of a similarly-sized formation of exclusively crewed aircraft.
Mass is only achievable if the platform delivering it is producible and affordable. The common dual-use baseline behind Thunder drives the economies of scale, expanded demand, and broad supply chains critical to drive down costs and de-risk the pathway to large-scale production.
Formation-Based Autonomy
The advantages that Thunder brings to the battlefield extend beyond its hardware - they are also defined by the centrality of software and autonomy to its performance. Anduril’s core Lattice for Mission Autonomy software delivers the trusted, flight-proven formation behaviors, separation management, and flight logic necessary for Thunder to remain useful, predictable, and safe around crewed aircraft. By translating operator intent into trusted machine-speed route, timing, tasking, and deconfliction decisions, Lattice eliminates the need for pilots to manage Thunder with a stick and rudder, enabling them to focus instead on the most important decisions at hand.
This feature is especially important as the future of attack aviation emerges. Terrain, obstacles, threats, and degraded visual environments make the kind of high-speed, low-altitude operations flown by attack helicopters uniquely complex — whether for a manned platform or an autonomous one. Anduril, however, has specifically designed Thunder from the start to meet this task. With sophisticated onboard machine perception, vehicle autonomy, and flight-proven collaborative mission autonomy software, Thunder can maneuver with the formation, share data in real time, coordinate effects, and act on pilot intent, delivering a trusted autonomous wingman that can keep up with, defend, and empower the pilots flying the most congested airspace on the battlefield.
Being able to see and decide at machine speed is what enables Thunder to fly near-surface missions at pace. Thunder’s multi-modal machine perception stack and sensor suite combines passive and selective active sensors with onboard computer vision, map data, and edge compute, enabling Thunder to continuously detect, classify, and track terrain, obstacles, and threats. That sensor data provides the inputs necessary to facilitate the visual navigation, inertial positioning, and terrain feature mapping that enable Thunder to remain on course when GPS, visibility, and communications are degraded or denied.
Lattice multiplies the situational awareness of every platform on the battlefield, fusing sensor, threat, and mission data from each platform to generate a common, formation-wide tactical operating picture. Software ensures not only that Thunder is able to perform its own mission, but that it actually enhances the effectiveness of every platform around it.
A New Era of Attack Aviation
Thunder is urgently needed today. Anduril, Archer, and a team of industry partners are already hard at work developing this capability, leveraging proven technologies to accelerate development and de-risk performance. Anduril has already completed multiple test flights with full-scale surrogate aircraft. Thunder’s first flight is planned for 2027.
The near-surface fight has become one of the most lethal parts of the battlefield. By combining the range and speed necessary to penetrate contested airspace, the autonomy required to maneuver and team with crewed aircraft, and the payload capacity to overwhelm sophisticated defenses, Thunder brings the combination of capabilities necessary to achieve maneuver dominance on the modern battlefield.
