Ornadyne’s O1 ornithopter drone successfully evaded sensor detection at the Air Force’s “Game of Drones” 26-3 exercise this September at Edwards Air Force Base.
By mimicking the flight mechanics and visual silhouette of a crow, the one-pound UAS bypassed counter-UAS systems that failed to classify the craft as a man-made threat.
Ornithopter Mechanics Replace Traditional Rotors
Most tactical unmanned aerial systems rely on high-RPM brushless motors and propellers, which generate distinct acoustic and radar signatures. The Ornadyne O1 shifts the architecture entirely by utilizing wing-flapping kinetics. This mechanical shift not only reduces the acoustic profile but also creates a biological signature that legacy detection algorithms are currently ill-equipped to interpret.
“It looks like a bird, it moves similar to a bird, and humans and counter-UAS systems can misclassify it as a bird,” co-founder Armen Arakelyan stated in a Department of Defense release. Arakelyan, a former SpaceX engineer, designed the system to prioritize low-altitude surveillance while blending into local avian populations.

Sensor Evasion at Edwards Air Force Base
During the September 17, 2026, demonstration at the Mojave Desert facility, the O1 proved that passive camouflage—specifically, the ability to match the color, wingspan, and silhouette of native species—functions as a viable electronic warfare countermeasure. The test was conducted under the oversight of the Air Force 412th Test Wing’s Experimental Test Force and the Defense Contract Management Agency’s Blue List team.
The O1’s performance highlights a critical gap in current identification, friend or foe (IFF) protocols. If a system classifies an object as biological, it is often filtered out by automated defensive nets to prevent false positives in high-clutter environments. Ornadyne’s hardware exploits this signal-processing bias, essentially forcing a “no-action” state in counter-UAS sensor suites.

The Global Race for Biomimetic Surveillance
The U.S. military is not alone in exploring ornithopter technology. In 2024, footage emerged showing Chinese Jiaolong Commandos deploying bird-like drones, showing the race for low-observable, biomimetic UAS is a global priority. These systems represent a departure from the high-speed, high-signature drones that have dominated the last decade of conflict.
“We learned during ‘Game of Drones’ that sensors deployed by the other companies here could not establish our drone using their detection equipment,” co-founder Geourg Kivijian noted following the exercise.
O1 Replicates Natural Environments to Enable Undetected Military Operations
The integration of the O1 into broader military operations depends on the Blue List team’s ongoing verification process. As the military moves toward more autonomous, low-altitude intelligence, surveillance, and reconnaissance (ISR) tools, the ability to operate undetected within a contested environment becomes a primary requirement for commercial vendors.
For now, the O1 serves as a proof-of-concept that the most effective way to hide in plain sight is not to use stealth coatings or electronic jamming, but to replicate the natural environment itself.
