Swarm Aero has taken delivery of the first of the Honeywell TPE331 engines that will power its new large uncrewed air system.

Honeywell Aerospace’s TPE331 turboprop engine will power a multi-mission uncrewed air system (UAS) being developed by Swarm Aero. The first propulsion system has already been supplied to be installed on what Swarm said on June 9 will be a production-ready aircraft. Swarm has not confirmed the size, payload, and range of its UAS, but said that it falls within the Group 5 class defined by the U.S. Department of Defense.

This would generally include designs weighing more than 1,320 pounds, with a payload greater than 1,000 pounds and the ability to operate above 18,000 feet. According to the California-based company, it is contracted under multiple unspecified Pentagon contracts.
