  • Swarm selected the commercially available Honeywell TPE331 as the powerplant for its large, multi-mission Group 5 uncrewed aircraft.
  • Initial propulsion systems had already been supplied under the contract, and the companies were working together on aircraft design, development, maintenance and operations.
  • Honeywell reported 13,000 TPE331 engines delivered and 122 million flight hours; Swarm is using the established platform to reduce cost and production risk.

Swarm Aero is a defence unmanned-systems company building UAV swarms, onboard collaborative autonomy, and swarm-scale command-and-control software. The company positions its stack around aircraft designed from the ground up for swarming, with mission software that lets small teams coordinate large numbers of uncrewed vehicles in communications-limited, contested environments.
