NX3 – a UK-sovereign, dual-use heavy-lift UAS, engineered as one system.

NX3 is a heavy-lift autonomous aircraft built for the missions that fall between what off-the-shelf drones can carry and what large military systems can reach. It lifts serious payloads, flies real distances, and keeps working in conditions and airspace that defeat lighter platforms. The airframe, the systems integration, and the sovereign autonomy layer have all been designed in-house in Wales and proven across three generations of hardware – engineered from the outset to move towards a fully sovereign UK supply chain (currently 86%+ UK parts).

Maturity: Core platform at TRL 6, on an evidenced pathway to TRL 7. Autonomy and navigation layer at TRL 5-6. This is a mature system with flight hours behind it, not a concept or a demonstrator.

NX3 isn’t an assembly of bought-in parts wrapped in a frame. It’s an integrated platform where the airframe, propulsion, power, avionics, and payload architecture were designed to work together from the first line in CAD.

The aircraft uses a four-arm rotary-wing configuration with large-diameter rotors sized for lift efficiency, a structural core built from composite and alloys, and modularity that lets the same airframe conduct very different missions.

The result is a platform that’s strong where it needs to be, light everywhere else, and serviceable in the field rather than only on a bench.

A composite and titanium structure engineered for the hardest trade in aviation: maximum strength at minimum weight. Each generation has driven structural mass down without giving up rigidity or durability, because every kilogram saved is returned directly to payload, range, or safety margin. The airframe is designed to take real-world handling – transport, field deployment, repeated launch and recovery – not just controlled test conditions.

An all-electric propulsion and power system, designed as an integrated whole rather than a parts list – balancing thrust, efficiency, weight, and the practical reality of keeping an aircraft flying and serviceable away from base. Power architecture is matched to the lift demands of a heavy platform, with reliability treated as a first-order design requirement, not an afterthought.

The navigation intelligence of the aircraft sits on a UK-controlled avionics and autonomy layer that we design, understand, and can stand behind. That means flight behaviour that is auditable and trusted rather than borrowed from a black box – a distinction that matters increasingly to serious civil and defence operators who need to know exactly what their aircraft is doing and why.

NX3 is designed to keep knowing where it is and what it’s doing when conventional satellite navigation can’t be relied upon – denied, jammed, or simply unavailable. It does this through alternative sensing and the intelligent fusion of multiple independent position sources, so the platform degrades gracefully instead of failing when the sky stops cooperating. For missions where you can’t assume a clean GNSS signal, this is the capability that makes the difference.

One airframe, many missions is our mantra. The main airframe, landing gear and payload attachment and release system architecture is built to be reconfigured – survey and inspection sensors, logistics and delivery loads, search-and-rescue equipment, or mission-specific defence payloads – without redesigning the aircraft around each task. Capability proven in one role strengthens every other.

NX3 instills pilot confidence from the outset and this is achieved through the use of the pilot interface, designed to keep the operator in command without burying them in complexity. The aim is an aircraft that an operator can deploy and trust quickly, with the autonomy doing the heavy cognitive lifting and the pilot retaining clear, confident control.

The same platform serves both sides of the dual-use line. On the civil side: aerial survey and infrastructure inspection, heavy-lift logistics and delivery, search-and-rescue payload deployment, offshore energy support, disaster response, and scientific operations. On the defence and security side: ISR and reconnaissance, border and critical-infrastructure protection, logistics resupply to forward positions, and national-resilience support.
