Beehive Industries Achieves Major Breakthrough as Frenzy™ Engine Completes High-Altitude Testing, Paving the Way for First Flight in Early 2026
Beehive Industries, a rapidly rising American manufacturer specializing in advanced propulsion technologies for uncrewed aerial defense applications, announced a significant milestone today with the successful completion of high-altitude testing for its 200-pound-force (lbf) class Frenzy™ engine. This accomplishment represents a defining moment in the company’s accelerated development roadmap and confirms that the Frenzy engine is on track for its initial flight test campaign scheduled for the first quarter of 2026. In an environment where defense innovation is increasingly measured not only by capability but also by speed and scalability, the company’s achievement underscores Beehive’s mission to deliver operationally decisive propulsion systems “at the speed of need.”
The recently completed test campaign took place at a government-operated high-altitude propulsion facility located in Ohio, a site recognized for its specialized ability to simulate the extreme atmospheric conditions aircraft encounter at operational altitudes. Completing the full sequence of tests at this facility provides critical validation that the Frenzy engine can operate reliably, efficiently, and safely across the entire flight envelope — from takeoff and climb through cruise and high-altitude maneuvering. With these results, Beehive has now fulfilled a major developmental requirement and is positioned to transition smoothly toward the next phase: flight-ready hardware integration and rapid production expansion.
David Kimball, Chief Technology Officer at Beehive Industries, highlighted the significance of this achievement. “This milestone confirms Frenzy’s readiness for flight integration,” Kimball said. “What we’ve accomplished over the past year is extraordinary. In under twelve months, we progressed from conceptual architecture to proven high-altitude performance. This acceleration is a direct testament to the capability, dedication, and ingenuity of the Beehive engineering and manufacturing teams. Frenzy is now unquestionably flight-ready, and our production system is prepared to scale to meet emerging demand from our defense partners.”
A Year of Remarkable Progress
The successful high-altitude campaign is the culmination of a remarkable year for the Frenzy program, one defined by rapid iteration, progressive development milestones, and a strategy built around manufacturing efficiency and technical readiness. Earlier in September, Beehive announced that it had successfully completed ground testing of six Frenzy engines within a span of just four months — a pace almost unheard of in traditional aerospace propulsion development cycles. That announcement underscored both the maturity of the engine design and the company’s commitment to high-tempo engineering progress.
Following that achievement, Beehive shipped two prototype Frenzy engines to the government facility in Ohio in October, exactly on schedule. These prototypes were subjected to a rigorous series of high-altitude performance evaluations, including cold-start conditions, ignition stability, steady-state operation, transient performance, and durability testing under simulated mission stress loads. The testing validated the engine’s responsiveness, efficiency, and structural robustness across multiple operating conditions.
According to the company, results from the high-altitude campaign either met or exceeded stringent Air Force requirements across all major evaluation metrics. Those metrics included ignition performance at altitude, throttle response, turbine temperature behavior, structural durability, and thrust-specific fuel consumption — all crucial parameters that determine whether an engine is not only technically viable but also mission-capable.
Key Test Highlights
To summarize, the Frenzy engines demonstrated several critical performance benchmarks:
- Successful ignition and sustained operation across the full flight envelope, including challenging high-altitude conditions where air density and temperature typically stress small turbine engines.
- Rapid acceleration from ignition to full operating speed, confirming the engine’s suitability for fast-response mission profiles that require immediate thrust availability.
- Turbine inlet temperatures and fuel efficiency surpassing predicted values, indicating optimized combustion and superior thermal performance relative to initial modeling.
- Hardware that remained in “like-new” condition after enduring mission-equivalent runtime, showcasing exceptional durability and confirming that engineered materials and additive-manufactured components are performing exactly as intended.
These results are particularly notable because Frenzy is one of the first propulsion systems of its class to be designed using an “additive-first” approach, meaning that the engine architecture, components, and manufacturing methods were conceived with advanced additive manufacturing (AM) at their core. This strategy allows Beehive to unlock design geometries not achievable through conventional fabrication while compressing development timelines from multi-year processes to cycles measured in months.
Iterative Development at Operational Tempo
Kimball emphasized that the testing success is as much about the company’s engineering philosophy as it is about the engine itself. “This test campaign demonstrates not only the full potential of our engine but also the power of a highly iterative, cross-functional development program,” he explained. “Every milestone reinforces our confidence in the underlying architecture, our capacity to deliver on our commitments, and the disruptive trajectory we are establishing for next-generation propulsion. We are not just accelerating development timelines — we are ensuring America’s warfighters have access to the technology they need, precisely when they need it.”
Beehive’s program structure incorporates rapid design iteration, early manufacturing integration, tightly aligned engineering feedback loops, and aggressive but achievable milestone scheduling. This integrated framework enables the company to compress development cycles and respond immediately to test insights, significantly reducing the traditional barriers that slow aerospace innovation.
Flight Testing and Production Scaling
With flight testing scheduled to begin in early 2026, Beehive is now preparing to integrate the Frenzy engine with its first developmental flight vehicle. This integration phase represents the final validation step before entering low-rate initial production (LRIP), during which the company will begin delivering early units for operational evaluation.
To support this next stage, Beehive’s facilities in Denver, Cincinnati, and Knoxville are already ramping up manufacturing capacity. The company is investing heavily in additive manufacturing systems, propulsion assembly lines, quality control infrastructure, and talent expansion to ensure it can meet rapidly increasing customer demand for advanced propulsion systems capable of supporting next-generation uncrewed aerial systems (UAS).
A Program Backed by U.S. Air Force Investment
The rapid progress of the Frenzy program builds on the foundation of a $12.46 million contract awarded in October 2024 by the U.S. Air Force Rapid Sustainment Office (RSO) in partnership with the University of Dayton Research Institute (UDRI). This contract provided critical funding that enabled fast-cycle hardware development, expanded prototype production, and accelerated test sequencing. Following the engine’s official debut in December 2024, Beehive has remained on an aggressive delivery schedule aligned with Air Force priorities for affordable, highly reliable propulsion for uncrewed aerial platforms.
The Frenzy engine family — covering thrust classes ranging from 100 to 300 lbf — is designed to power a new generation of UAS platforms that require high efficiency, robust performance, and cost-effective manufacturability. With its advanced thermal behavior, strong structural integrity, and scalable design, the Frenzy family is positioned to become a cornerstone propulsion solution for defense programs seeking to expand mission capabilities while lowering lifecycle costs.
