Airbus has completed the purchase of US company Aerovel, which manufactures the Flexrotor unmanned aircraft system (UAS).

The European company announced the milestone on 7 May, saying it will strengthen its portfolio of tactical unmanned solutions.

“We see more and more armed forces and parapublic agencies around the world looking to investigate how unmanned aerial systems can strengthen their intelligence and surveillance capabilities,” Airbus said.

Based in Bingen, Washington state, Aerovel manufactures the Flexrotor, which is a rotary- and fixed-winged vertical take-off and landing (VTOL) unmanned aircraft designed for intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) missions at sea and over land. With a maximum take-off weight (MTOW) of 25 kg, the Flexrotor can operate for upwards of 14 hours while carrying a range of electro-optic/infrared (EO/IR) payloads.

Malaysian firm Malvus Sense unveiled the CW-25H, a new hydrogen-electric-powered vertical take-off and landing (VTOL) unmanned aircraft system (UAS), in collaboration with Chinese UAS firm JOUAV at the Defence Services Asia (DSA) 2024 exhibition held in Kuala Lumpur from 6 to 9 May.

Powered by hydrogen-electric hybrid technology, the CW-25H has a flight time of up to 330 minutes.

The two companies are collaborating on UASs for the Malaysian Armed Forces. JOUAV designs and develops drones, while Malvus Sense assembles them in Malaysia.

The CW-25H has a maximum service ceiling of 6,000 m and a cruising speed of 80 km/h. It is adaptable for various applications from infrastructure inspection to environmental monitoring.

Syed Omar Syed Mohamad, managing director of Malvus Sense, said, “The CW-25H represents a paradigm shift in aerial operations. Its hydrogen-electric hybrid technology not only extends endurance but also ensures environmental sustainability. We are proud to offer a solution that not only meets but exceeds industry standards, setting a new benchmark for efficiency, safety, and performance.”

Turkish company Aselsan has unveiled its latest radio relay system at the Defence Services Asia (DSA) 2024 exhibition held in Kuala Lumpur from 6 to 9 May.

The system, known as URAL, is an airborne software-defined radio relay operating in the very/ultra-high frequency (V/UHF) band.

URAL is designed for unmanned aerial vehicles (UAVs) and other airborne platforms for surveillance, reconnaissance, and mapping applications.

It utilises Aselsan's advanced network waveform features to achieve the high throughput data rate.

The VHF and UHF bands are incorporated in a single unit to reduce the system's size and weight to meet the low size, weight, and power (SWaP) requirement of UAVs. The company told Janes that older radio relays are available in single band only, either VHF or UHF frequency.

Aselsan's representative did not disclose the modulation type, data rate, and the waveforms incorporated in the system at the time of publication. Based on Janes
