In June, Wior’s firm raised $200 million, in a round led by Smash Capital, on the strength of its Bullfrog platform, which can respond to a drone threat in seconds by shooting them out of the sky with bullets. The Bullfrog system is light enough to mount on the back of a Toyota Tacoma and, most critically, it is scalable. Wior says ACS is currently cranking out 10 units a week and is poised to announce the opening of huge new manufacturing plants in Texas and Alabama that will let it ramp up to thousands of units a month.

The Bullfrog units are already making a difference in the Middle East theater where Iran has used cheap Chinese drones to kill American service members and blow up high tech kits worth billions of dollars. Their arrival also comes at a time when the U.S. has been using Patriot and Thaad missiles to counter drones—an unsustainable tactic that has reportedly cost $4 million per shot.

The early phase deployment of a cheap and effective drone deterrent is encouraging news, but so too are recent procurement changes at the Department of War that have made it possible for startups like ACS to supply the military in the first place. Those changes include the introduction of online shopping forums such as the Army UAS marketplace, which was launched in partnership with Amazon’s AWS, and that allows commanders to “buy and try” drones from vetted vendors. There is also a similar site for counter-drone kit called C-UAS marketplace.

“This means you let the Army buy whatever they like, and let the best rise to the top rather than trying to pick winners ahead of time,” says Wior. All of this suggests the U.S. could regain some of its military mojo by infusing Silicon Valley-style innovation into its warfighting capacities. When it comes to the drone situation, the country may have no choice.

According to retired Brigadier General Houston Cantwell, who recently finished a fellowship at the Mitchell Institute for Aerospace Studies, the goals of the Pentagon’s “Drone Dominance Program”—which calls for the annual production of 200,000 American-made drones—are laughable, and that China can easily outstrip that. He believes that focusing on making drone defense units is the way to go, and is cautiously optimistic about the recent changes to procurement policy.

“No one familiar with the DoD acquisition system is going to praise its agility but, in the last 18 months, the administration is starting to adapt,” said Cantwell, pointing to the C-UAS site as a particularly promising example.

All of this could be good news for American security, but also for investors. Wior wouldn’t share specific revenue figures but said ACS’s revenue, which came in around $10 million last year, is set to be in the “low nine figures” for 2026. ACS and other startups that offer anti-drone solutions, including Anduril and DroneShield, aren’t likely to go public for a while, but their shares are available on secondary platforms like Hiive and Forge.

Would-be investors should, of course, take all of these companies’ claims with a grain of salt, especially given recent talk of a defense tech bubble. If that’s the case, their VC investors could get blown up—hopefully just in the figurative sense. 

See you Monday,
