Unveiled at the 2026 Singapore Airshow, the DrN-600 is ST Engineering’s boldest move yet into the world of autonomous logistics. This medium-lift cargo drone isn't just a prototype; it’s a certification-ready powerhouse designed to bridge the gap between tiny delivery drones and full-sized crewed aircraft.

Developed in partnership with the Israeli-US electric aircraft pioneer AIR (the creators of the AIR ONE personal eVTOL), the DrN-600 is built for one thing: getting heavy goods to hard-to-reach places without a pilot in sight.

The Technical Breakdown: Power Meets Precision

The DrN-600 is the "big brother" of ST Engineering’s existing DroNet family. While its predecessors handled lighter tasks, this machine is a true workhorse.

• Maximum Take-Off Weight (MTOW): Just under 600 kg (approx. 1,323 lbs).

• Payload Capacity: It can carry up to 100 kg (220 lbs) of cargo.

• Impressive Range: Capable of flying up to 120 km (75 miles) on a single charge—nearly ten times the range of many current cargo multirotors.

• Wingspan: Spanning 8 meters (26 feet), it uses a "lift-and-cruise" configuration. This means it takes off vertically like a helicopter but flies forward like a plane for maximum efficiency.

• Propulsion: Fully electric, powered by high-density lithium-polymer batteries.

The Logistics Game-Changer: "Front-Loading" Innovation

Unlike many cargo drones that require loads to be slung underneath on a hook (which can sway in the wind), the DrN-600 features an enclosed 1.5-cubic-meter cargo bay.

In a clever nod to traditional logistics, the bay is designed to accept standardized pallets through a front-loading door. This allows it to plug directly into existing supply chains. Whether it’s delivering medical supplies to a remote island or resupplying a military unit in a mountainous region, the DrN-600 makes the "last mile" look easy.

Fun Facts & Trivia

1. The "Panda" Payload: A 100 kg payload capacity means the DrN-600 could theoretically transport a full-grown Giant Panda (or about 20 large bags of rice) across a 100 km distance in one go.

2. The "Power Tool" Approach: Much like your favorite cordless drill, the DrN-600 uses hot-swappable battery packs. Instead of waiting hours to recharge, ground crews can simply swap the "battery brick" and have the drone back in the air in minutes.

3. Silent but Steady: Because it’s all-electric, the DrN-600 is significantly quieter than helicopters, making it ideal for deliveries to noise-sensitive hospitals or residential areas.

4. A "Smart" Sibling: It was unveiled alongside Gemini-X (a tactical datalink) and AXIOS (a multi-payload delivery system), forming part of a new "Manned-Unmanned Teaming" ecosystem where drones and humans work together in real-time.

5. Beating the Competition: While the popular DJI FlyCart 100 can carry 100 kg, its range is limited to around 12 km. The DrN-600 is designed to go 10 times further, making it the "marathon runner" of the cargo drone world.

Why It Matters

For years, the "last mile" has been the most expensive and difficult part of delivery. By creating a drone that is robust enough for heavy cargo but simple enough to fly autonomously, ST Engineering isn't just building a new gadget—they're building the future of the autonomous supply chain. Whether it’s crossing the Kallang River or the South China Sea, the DrN-600 is ready to deliver.
