Flexrotor is a Group 2 small tactical vertical take-off and landing (VTOL) unmanned aircraft system (UAS). It has a maximum take-off weight of 25 kg (55 lbs) and is designed for Intelligence, Surveillance, Target
Acquisition, and Reconnaissance (ISTAR) missions for more than 14 hours in a typical operational configuration.

It can integrate different types of payloads, including an electro-optical system and advanced sensors to suit customers’ unique mission needs. With the ability to autonomously launch and recover from either land or at sea requiring only a 3.7 by 3.7 m (12 by 12 ft.) area, Flexrotor is ideal for expeditionary missions requiring minimal footprint. 

Unmanned aerial system (UAS), Flexrotor


Flexrotor delivers long endurance and high space weight and power (SWaP), enabling the expeditionary UAS to operate a wide array of sensors and capabilities. It can operate from confined land areas and from ships without flight decks, and its expeditionary capability makes it easy to transport and to go from stowed to airborne in less than 14 minutes.

Missions include: 

- Maritime warfare (signal Intelligence, electronic warfare, communications relay)
- Search and rescue 
- Parapublic (firefighting, humanitarian missions, border security)
- Civil applications (precision agriculture, geo mapping, wildlife observation & marine science)
