ACS opens new engineering office in Silicon Valley. Its new engineering facility in Mountain View, California, will hire electrical, software and computer vision engineering talent. Published on Sep. 21, 2026 Rose Velazquez Allen Control Systems, or ACS, an Austin-based company dedicated to precision robotics in the defense sector, recently announced the opening of its new facility in Mountain View, California. The new engineering office will focus on accelerating the company's autonomous precision capabilities for the U.S. and its allied forces. The company is equipping its customers to combat the growing threat of low-cost weaponized drones. Its new Silicon Valley office will house electrical, software and computer vision talent, complementing its Austin-based team to design, build and deploy systems that can defeat hostile drones at a lower cost than conventional interceptors. "With deep robotics expertise, our engineering team has already solved the incredibly complex problem of building a counter-drone system that is both cost-effective and scalable," Mike Wior, ACS co-founder and CEO, said in a statement. "With military targets and critical infrastructure acutely vulnerable to drone attacks, we will innovate and build with speed to meet this pressing threat. We are tapping into the unique talent market of Silicon Valley to continue to deliver essential capabilities to warfighters as quickly as possible." The Mountain View office opening coincides with ACS's major manufacturing expansion in Austin. The initiative aims to scale production of the company's autonomous weapon station, Bullfrog, which leverages computer vision, autonomous control and precision robotics and existing weapon systems to provide scalable counter-drone solutions.

How Silicon Valley just might save America from the growing drone threat. 6 4 minutes read Jeff John Roberts here. This drone threat is giving me the chills. Weeks after the FBI busted a plot to launch explosive-laden drones at the White House, a U.S. Army division engaged a Ukrainian drone unit in a war games exercise - and got whupped so thoroughly they had to "respawn" to keep going. It feels like Americans in combat (and here at home) are sitting ducks for these lethal and inexpensive airborne weapons. That's why it was refreshing to hear some good news from Mike Wior, the CEO of defense tech startup Allen Control Systems (ACS). 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.

The US Marine Corps has contracted Allen Control Systems to integrate its Bullfrog autonomous weapon system into the Light Marine Air Defense Integrated System counter-drone platform. The system uses artificial intelligence and computer vision to control standard military firearms, including M240 and M2 machine guns, to target drones and ground threats. Unlike purpose-built counter-drone systems, Bullfrog adapts existing weapons to detect and engage targets autonomously, which ACS claims is more cost-effective than expensive interceptor missiles. The M240 variant fires up to 850 rounds per minute and can neutralise drones weighing up to 600 kilogrammes operating at altitudes below 5,500 metres. The US Army and Navy already deploy Bullfrog systems. ACS cited the widespread use of inexpensive drones in conflicts in Ukraine and the Middle East as justification for developing affordable counter-drone technology.
