Rugged VTOL UAVs & High-Performance Propulsion Systems

Rotron Aerospace is a specialist developer of rugged VTOL UAVs (unmanned aerial vehicles) and high-performance propulsion systems that deliver industry-leading and transformative capabilities for military and government applications.

dt-300 VTOL UAV PlatformThe company’s pioneering electric and hybrid drone platforms offer enhanced range and endurance as well as class-leading payload capabilities, with ultra-quiet operation for maximum covertness.

These advanced and game-changing UAS have been successfully deployed around the world by a wide range of clients.

Rotron’s aircraft propulsion systems and rotary engines offer unparalleled power-to-weight performance with virtually no vibration, and have been selected by some of the world’s largest aerospace OEMs.

Electric & Hybrid VTOL UAS

Talon DT-300

Multi-role VTOL UAV with 45 kg payload capacity

The Talon DT-300 is a highly reconfigurable fully electric VTOL UAS that is ideal for a variety of critical military and government missions, including ISTAR, cargo delivery, humanitarian aid, and target detection, identification, and tracking. Featuring a unique dual-rotor design inspired by the CH-47 Chinook cargo helicopter, it offers class-leading and cost-effective performance with superior payload and range, and ultra-low operational radar and acoustic signatures for maximum covertness. Built in the UK, the system is not reliant on Far Eastern components.

Talon DT-300 UAVThe aircraft’s highly optimised and stable aerodynamic design utilizes tandem counter-rotating rotors, removing the need for a tail rotor and ensuring that all power is used for generating lift. Active blade pitch control allows the platform to harness translation lift during forward flight. These capabilities enable the Talon DT-300 to outperform traditional multirotor designs by a factor of up to four times.
Talon DT-300 Rotor

The Talon DT-300 is equipped with a NextVision Raptor EO/IR gimbal as standard. Its 45 kg payload capacity also allows it to act as a mothership capability, enabling smaller FPV drones to be launched directly from its modular carrier rack for extended BVLOS operations.

The ultra-lightweight carbon composite fuselage is foldable for maximum portability and convenience, providing a highly transportable form factor that can be carried and loaded by two people into a small vehicle.

Talon DT-300X

Hybrid electric helicopter UAV for long-range ISTAR, logistics resupply & strike missions

Talon DT-300X unmanned helicopter

The Talon DT-300X is a hybrid version of the DT-300, featuring Rotron’s hydrocarbon-fuelled RT150 aero-engine, which recharges the electric batteries to provide longer battery life and unparalleled range and endurance. Capable of flying for up to 5 hours and 400 km, it is designed for a variety of mission types including extended ISTAR (intelligence, surveillance, target acquisition, and reconnaissance), cargo delivery and logistics resupply, anti-submarine warfare support, and deep strike.

Talon DT-300X Hybrid electric unmanned helicopter

The RT150 aero-engine can be easily removed to convert the DT-300X into a fully electric platform. With a low logistical footprint, the IP67-rated aircraft can be folded down into a highly compact form factor, and can be deployed from urban areas, remote regions, or vessels and marine platforms.

Like the DT-300, the DT-300X is also ideal as a mothership platform for extended-range deployment of short-range FPV drones and decoys.

Talon DT-150

Rugged ultra-compact Group 2 unmanned helicopter with 22.5kg payload capacity

Talon DT-150 electric helicopter UAS

The Talon DT-150 is an ultra-compact fully electric Group 2 helicopter UAS platform designed as a smaller counterpart to the DT-300. With a maximum payload of 22.5 kg, it is ideal for battlefield logistics, as well as a range of other mission-critical applications such as ISR and search and rescue. The versatile aircraft can also be used as a mobile launch platform for the deployment of up to three smaller FPV drones.

Talon DT-150 helicopter UAVThe rugged UAS is highly resilient against wind and weather, offering IP67-rated waterproofing as well as excellent stability and control in high crosswinds or turbulence. It features a foldable design with detachable rotor blades, allowing it to be packed down into an easily transportable case that fits in a standard SUV.

The Talon DT-150 is equipped with hardened GPS and frequency-hopping datalinks, ensuring continued availability and security even during EW and jamming and spoofing attacks.

Defendor

High-speed long-range UCAV & One Way Effect platform

defendorDefendor is Rotron’s next-generation Uncrewed Combat Aerial Vehicle (UCAV) and One Way Effect (OWE) platform, engineered for long-range strike and massed deployment. Powered by the R250-FDS Fan Drive System, it delivers exceptional efficiency and SWaP-C performance, enabling ranges of 1,000 km or greater and speeds up to 650 km/h while carrying a substantial payload at low unit cost.

The design supports scalable combat mass through simple supply chains for rapid, high-volume production and is suitable for strike missions, swarm employment, and integration into layered air defense concepts. Fully designed, specified, and integrated in the UK, Defendor provides sovereign assurance and a low logistical burden, closing the capability gap between tactical drones and traditional combat aircraft.
