Ornadyne's 1-Pound Flapping Drone Registered as a Bird at Edwards, in a Test With No Published Detection Rate

A flapping-wing drone built by Ornadyne, a Los Angeles startup with a team of four, registered as a bird on other companies' detection sensors during the Air Force's Game of Drones 26-3 exercise at Edwards Air Force Base on September 17, according to Task & Purpose. The result comes from the company's own account of the test; no sensor maker, detection rate or number of passes has been published.

The exercise was run by the 412th Test Wing's Experimental Test Force and the Defense Contract Management Agency's Blue List team, and the Mojave base hosts drone exercises each quarter, per Task & Purpose. It was the first time Ornadyne had flown against detection systems built by other private companies.

What the O1 is, by the numbers

The O1 is an ornithopter, a drone that flaps its wings instead of using propellers. Specifications below come from a company fact sheet quoted by Task & Purpose, and none has been independently measured.

Specification	Ornadyne's figure
Weight	1 lb
Range	Up to 10 km (about 6 miles)
Endurance	More than 1 hour
Payload	Small, such as a camera for target recognition
Wingspan and unit cost	Not stated

The company says it can change the O1's colour, wingspan, proportions and silhouette to match a bird species native to the area it operates in. A 1 lb airframe with a camera-sized payload is a reconnaissance platform, not a munition carrier, and an hour of endurance at that weight puts it in the class of small hand-launched fixed-wing drones rather than the quadcopters that dominate current battlefield use.

What the founders said

Armen Arakelyan, who Y Combinator lists as founder and chief technology officer and who previously worked on Starship components at SpaceX, told Task & Purpose: "It looks like a bird, it moves similar to a bird, and humans and counter-UAS systems can misclassify it as a bird."

Geourg Kivijian, the founder and chief executive, previously at NASA's Jet Propulsion Laboratory and Astrolab, said "sensors deployed by the other companies here could not establish our drone using their detection equipment" and, of the result, "It registered as a bird, which is exactly what we wanted."

The Y Combinator listing for the Spring 2026 batch describes the product as "robot birds for surveillance" with "hour-class flight times" and "low acoustic signatures", and gives no figures.

What is missing

The test result is a single sentence of evidence. Task & Purpose does not report which sensors were used, whether they were radar, optical or acoustic, how far away the O1 flew, or how many times it was classified. A bird misclassification at long range by a radar tuned to ignore birds is a weaker result than one at 200 metres by an optical system trained on birds, and the account does not separate them.

There is also no operational data: no unit cost, no customer, no flight in wind or rain, and no figure for how noisy the flapping mechanism is, even though Kivijian says the drone is quieter than propeller designs. A one-hour endurance claim and a 10 km range are both company figures from a fact sheet.

The military question runs the other way too. The same behaviour that fools a counter-drone sensor is a problem for a base trying to tell a surveillance drone from a flock of crows. Our earlier coverage of Renault's Forefront ground robot and of Nominal's $240 million Series C shows how much of this market is still announcements and renderings.

What happens next

Ornadyne says it is pursuing demonstration partnerships with military stakeholders. The next evidence that would matter is a test with named sensors, repeated passes and a published classification count, run by someone other than the company.
