A small unmanned aircraft that runs on solar power alone completed its first flight at an airport in north-west China on November 11, 2026. Named Light Cavalry, it was developed by the China Academy of Aerospace Aerodynamics, the 11th Academy of China Aerospace Science and Technology Corporation (CASC). Chinese reports describe it as the country's first small-to-medium solar-only aircraft built for the commercial market rather than as a research demonstrator.
On the test the aircraft started its motor, taxied, took off, climbed to its planned altitude, circled the field and landed. The developer says flight control, avionics, energy storage and handling were all checked and worked normally. This was a first flight only. The 30-hour figure quoted for the aircraft is a design maximum, and no long-endurance flight has been reported so far.
The airframe is 3.2 m long with an 8 m wingspan and a take-off weight of 45 kg. Solar cells laid across the wing are its only source of power. The design ceiling is 7,000 m and the payload capacity is more than 5 kg. It is launched from a vehicle, so it needs no runway, and preparing it on the ground takes about 20 minutes. The payload section is modular, so communications relay or remote-sensing equipment can be swapped in quickly.
Most solar aircraft known for long flights are large, with wingspans from about 25 m to more than 70 m and dedicated ground teams. Making the concept smaller is harder, because a short wing collects less sunlight relative to the weight and power draw of the aircraft. That pushes designers toward lighter materials, more efficient motors and better energy storage. The developer says Light Cavalry was designed around low cost and fast volume production.
Planned uses include patrols of roads, railways, power lines and long pipelines; checks on reservoirs, rivers and embankments; land surveying and natural resource surveys; monitoring of forests, grassland and desertification; fast surveys of areas hit by floods, geological hazards or forest fires; and monitoring of coastlines and port areas. The next steps are more rounds of test flights, work on energy storage and solar conversion, a design freeze and then commercial delivery. No price or delivery date has been announced.
What this means for buyers: Light Cavalry is not on sale yet, but it shows Chinese developers taking solar drones from the laboratory toward a small, vehicle-launched format that one field crew can handle. For pipeline, power line, mapping and environmental monitoring work, ask any supplier how endurance changes with season, latitude and cloud cover, because solar output drives every endurance figure, and how much stored energy is left for night flying or poor weather.
