UAV Turbines is developing a microturbine engine specifically for Group 3 unmanned aerial vehicles (UAVs), and the company believes the engines will be more reliable than the reciprocating engines commonly used in this class of aircraft.
UAV Turbines believes its Monarch 5 class of engines could improve US Army UAV propulsion in the smaller Group 3 and Group 4 range. The company has three different Monarch 5 models: turboshaft, turbogenerator, and turboprop. UAV Turbines also has a small Monarch 1 turbogenerator.

The Monarch 5 engines include a through-the-shaft, full authority digital engine control (FADEC), hydraulically-actuated variable pitch mechanism. UAV Turbines introduced a lightweight recuperator for the first time in a flight weight micro turboprop, providing better fuel efficiency.
