The US Army has experimented with a 3D-printed drone it developed using input from frontline troops, aiming to produce equipment grounded in real battlefield needs.
Built with soldier feedback incorporated early in the design process, the Soldier Portable Autonomous Reconnaissance Transitioning Aircraft (SPARTA) is capable of flying up to 30 kilometers (18.6 miles).
It weighs just over two pounds (0.9 kilograms) and combines the vertical takeoff and landing capability of a helicopter with the forward flight of a fixed-wing aircraft.
That hybrid configuration is designed to give it more mission endurance compared to conventional quad-rotor drones, enabling flight times beyond one hour at altitudes of around 500 feet (152 meters).
Its 3D-printed airframe can be produced overnight, and the entire system can be assembled rapidly without the need for specialized tools.
Built for Scale and Affordability
Researchers at the Army Research Laboratory (ARL) see SPARTA as a scalable platform that could be mass-produced at a fraction of the cost of conventional drones.
Priced at just over $1,000 per unit, the system is intended to be both replaceable and resilient enough to withstand significant crash damage.
Its modular design allows electronic components to be swapped out within minutes, while a large internal payload bay enables soldiers to configure different camera systems depending on mission needs.
More Users, More Feedback
SPARTA made its debut at the Best Drone Warfighter Competition in Alabama, where it demonstrated its intelligence, surveillance, and reconnaissance capabilities.
Senior army officials and soldiers in attendance provided additional feedback, contributing to ongoing refinements of the system.
“Our team at ARL has been working on new types of small unmanned aerial system designs for several years,” ARL Mechanical Engineer Dr. John Hrynuk said.
“When soldiers visited ARL last spring, they expressed the need for a lightweight, modular drone that could be easily assembled, repaired, and adapted in the field.”
Hrynuk’s team plans to deploy SPARTA to other operational units and gather feedback from users with different mission profiles.
The ARL team is also working with industry partners to transition the system toward serial production.
