DrN-600

DrN-600 is an all-electric, vertical-takeoff-and-landing (VTOL) cargo drone co-developed by ST Aerospace of Singapore and the Florida-based advanced air mobility company AIR, unveiled at the Singapore Airshow media preview on 1 February 2026. It is designed for medium-lift air cargo delivery and is, by ST Engineering's own description, its largest uncrewed cargo aircraft to date.

Overview

ST Engineering's press materials for Singapore Airshow 2026 described DrN-600 as "a next-generation unmanned aircraft system for medium-lift air cargo delivery," developed with AIR, which supplies the aircraft's core flight architecture shared with its piloted AIR ONE and a larger cargo eVTOL under development. DroneLife reported that the programme keeps the aircraft's maximum take-off weight just under 600 kg so operators can work within existing European and Asian aviation frameworks, such as the EASA light-UAS category, rather than under the heavier rules that apply above that threshold; one DroneLife report nonetheless described the design weight as exactly 600 kg, so the precise figure has not been confirmed to kilogram accuracy.

Janes reported in February 2026 that DrN-600 is ST Engineering's first medium-lift cargo UAS and said the companies describe it as "designed from the outset as a dual-use system," with civil logistics as the near-term goal and military logistics as a stated future possibility. In July 2026, ST Engineering signed a memorandum of understanding with the California firm Odys Aviation to design a new propulsion system aimed at extending the aircraft's range; the companies gave no performance figures or timeline for that follow-on work, and no catalog entry yet exists for an updated variant.

Design and capabilities

DrN-600 is built around a central fuselage with an 8 m wing and a twin-fin tail for forward flight, and lifts off vertically using four pods, each housing a pair of co-axial, electrically driven rotors. The aircraft is fully electric, powered by lithium-polymer batteries, with no combustion or hybrid-electric component at launch. It carries a front-loading cargo bay sized for standardised pallets and rated for up to 100 kg of payload, intended for time-sensitive deliveries such as medical and other supplies to islands and mountainous areas with limited ground access. Reported range figures differ between sources: Janes gives "over 70 km," while DroneLife reports "70 to 100 km"; neither a manufacturer specification sheet nor a resolution of the discrepancy was available at the time of writing.

Use cases

ST Engineering and AIR present DrN-600 primarily as a commercial logistics aircraft for last-mile and time-critical cargo to remote or infrastructure-limited sites. Janes additionally reports that the companies have designed the airframe to be adaptable to military logistics roles, though no defence customer or contract has been named.

Frequently asked questions

How much can the DrN-600 carry?

Up to 100 kg, in a front-loading bay sized for standardised pallets, according to Janes and DroneLife.

How is the DrN-600 powered?

Fully by electric motors and lithium-polymer batteries; ST Engineering and Odys Aviation signed a memorandum of understanding in July 2026 to develop a new propulsion system for a longer-range version, but no specification has been published.

What is the range of the DrN-600?

Sources disagree: Janes reports "over 70 km," while DroneLife reports "70 to 100 km." Neither manufacturer has published a definitive figure.

Has the DrN-600 flown yet?

As of October 2026, no source confirms a first flight; ST Engineering targeted baseline flight trials for the second or third quarter of 2026 and certification around 2028.

Who makes the DrN-600?

ST Aerospace (part of ST Engineering) of Singapore, co-developed with the US advanced air mobility company AIR.
