Kraus Hamdani Aerospace (KHA) and PowerLight Technologies have successfully demonstrated laser-based wireless power beaming to the K1000ULE unmanned aerial vehicle at Shaw Air Force Base in South Carolina — a milestone that could fundamentally change how long-endurance military drones operate in the field.
What Happened at Shaw AFB
The demonstration took place at the AFCENT Battle Lab, hosted in coordination with CENTCOM and the Operational Energy Innovation office. During the event, the K1000ULE — KHA's high-altitude, long-endurance (HALE) UAS — was sustained in flight using power transmitted wirelessly via laser rather than relying on onboard battery reserves alone.
The core achievement here is significant: the drone remained airborne and continued conducting Intelligence, Surveillance, and Reconnaissance (ISR) operations without requiring a ground recovery to recharge or refuel. In practical terms, that means an operator could theoretically keep the platform on-station indefinitely, so long as the ground-based laser system continues to beam energy to the aircraft.
How Wireless Power Beaming Works
Wireless power beaming — sometimes called power-over-laser or optical power transmission — works by converting electrical energy into a focused laser beam on the ground, then transmitting that beam to a photovoltaic receiver mounted on the aircraft. The receiver converts the light energy back into usable electrical power to charge the drone's batteries or directly power its systems.
PowerLight Technologies is one of the leading companies developing this capability, and their collaboration with KHA represents one of the more operationally relevant demonstrations of the technology to date. Unlike microwave-based wireless power transfer, laser beaming can be highly directional and efficient over longer distances, making it better suited for aerial applications.
Why This Matters for Military ISR
Persistent ISR is one of the most demanding requirements in modern military operations. Traditional battery-powered drones face a hard ceiling on how long they can stay aloft before needing to land — exposing the aircraft to ground threats, interrupting the surveillance feed, and requiring personnel to retrieve and reservice the platform.
- No ground recovery required during active ISR missions
- Continuous on-station time limited by mechanical reliability rather than energy storage
- Reduced operational footprint — fewer relaunch cycles means fewer personnel and less logistical exposure
- Harder to deny coverage to adversaries who might time actions around drone recharge windows
For a platform like the K1000ULE, which is already designed for extended endurance operations, adding wireless power replenishment could make it a genuinely persistent surveillance asset rather than one constrained by battery capacity.
The K1000ULE Platform
The K1000ULE is KHA's flagship long-endurance unmanned aircraft, built for high-altitude operations and optimized for persistent ISR missions. The platform has been designed with military and government customers in mind, emphasizing quiet operation, endurance, and sensor payload flexibility.
What Comes Next
While this demonstration marks a meaningful proof-of-concept in an operationally relevant environment, it's worth noting that the technology still faces real-world challenges before it becomes a standard capability. Atmospheric conditions, line-of-sight requirements, and laser safety protocols all factor into how and where this system can be deployed effectively.
That said, the involvement of CENTCOM and the Operational Energy Innovation office signals serious institutional interest from the U.S. military in maturing this capability. Demonstrations at active Air Force installations tend to be a step toward formal evaluation programs rather than one-off science projects.
For the broader drone industry, this is a reminder that the next leap in endurance won't necessarily come from better batteries — it may come from eliminating the need to land in the first place.
