Beehive sets October altitude test for Frenzy UAV engine, targets flight trials in early 2026
Beehive Industries plans to altitude-test its Frenzy UAV engine in October and move to flight testing in early 2026.
The propulsion startup is developing the low-cost, additively manufactured engine family under a $12.4 million agreement with the University of Dayton Research Institute backed by the U.S. Air Force. A 200-pound version has completed acceptance testing and is set to be shipped to the Air Force Research Laboratory facility in Ohio for altitude runs. Beehive says Frenzy is aimed at unmanned systems used for Air Launched Effects and counter-drone missions, where low cost, higher output and faster production could shape procurement decisions.
Beehive said it has sharply compressed the development cycle since launching the program. The company reached its first engine-to-test milestone within five months and has since been turning out a new engine every six weeks. Four Frenzy variants tested so far span diameters of five to eight inches and the 100- to 300-pound class. According to the company, all have completed performance and operability validation, durability validation and environmental stress testing. Beehive said each engine exceeded target power and specific fuel consumption goals and demonstrated more than a full mission of operational durability. Combined runtime has topped 20 hours.
A key element of the effort is proving the design can be built outside Beehive’s own factory. Under the contract scope, the University of Dayton Research Institute will receive the engine design and manufacture it independently to validate third-party producibility. Beehive also says Frenzy is designed to be usable immediately after more than 10 years in storage, a feature that could matter for attritable unmanned systems that must be bought in volume and fielded quickly. The company has not disclosed which aircraft will carry the engine in next year’s flight demonstration.
If altitude and flight testing stay on track, Frenzy could give the Air Force a new path to cheaper, scalable propulsion for expendable UAVs with longer reach. That would support larger inventories, lower unit costs and broader use of unmanned aircraft in strike-extension and counter-drone roles.
