Fortem Technologies is a privately held airspace security company headquartered in Lindon, Utah. It develops systems that detect, track, classify and intercept hostile or unauthorized drones. Its SkyDome platform combines TrueView sensors, command and control software and autonomous DroneHunter interceptors.
The company works with military, government and commercial organizations, including defense installations, airports, energy infrastructure, law enforcement, prisons and public venues. Its technology has been deployed in Ukraine, the Middle East and East Asia.
Fortem was founded in 2016 by Adam Robertson and Timothy Bean. Robertson remains chief technology officer, while Jon Gruen serves as CEO. The company focuses on protecting controlled and sensitive airspace from unauthorized drone activity.
Fortem Technologies has closed a $50 million Series B funding round led by Lockheed Martin. Lockheed Martin committed $25 million in the first tranche of the round in April 2026, while Unusual Machines and other strategic and institutional investors joined the completed financing.
The funding comes as governments and military organizations increase spending on systems designed to detect and stop unauthorized drones. The Federal Aviation Administration currently reports more than 837,000 registered drones in the United States and more than 481,000 certificated remote pilots.
Fortem has also expanded its government work. The company secured a multimillion dollar Department of Homeland Security contract connected to protecting venues during the 2026 FIFA World Cup, as well as a U.S. Army contract covering installations worldwide.
Counter unmanned aerial systems, commonly called C UAS, are designed to identify and stop drones that may pose a security threat. These systems can combine radar, software and interception technology to help operators understand what is flying in controlled airspace and decide how to respond.
In August, Fortem was selected as the only small business serving as a prime contractor on a five year Department of Homeland Security counter drone hardware and software contract. The contract has an estimated initial ceiling of $1.011 billion.
Fortem is also integrating its technology with Lockheed Martin's Sanctum C UAS architecture, which combines different sensors and response systems into a broader airspace protection setup.
“Our partners need counter-UAS capabilities that can move faster than the threat. They need solutions they can field quickly, scale in volume and adapt rapidly. That’s why we’re investing ahead of the need. This collaboration reflects our shared commitment to delivering the right capability, at an affordable cost, and at the speed of relevance.” — Stephanie C. Hill, President, Lockheed Martin Rotary and Mission Systems.
Fortem will use the Series B capital to increase manufacturing at its facility in Lindon, Utah, and expand global deployment of its SkyDome Family of Systems.
The company plans to produce more TrueView radar systems and DroneHunter interceptors as deployments expand across military, government and commercial environments.
SkyDome combines three main elements. TrueView sensors detect and track objects in the air, command and control software classifies them and coordinates a response, and DroneHunter autonomous aircraft can intercept drones identified as threats.
“The threat is real, demand is here, and our technology is proven in real-world environments – from the Middle East to Europe to the World Cup. This capital lets Fortem scale to meet accelerating demand for our products.” — Charlie O'Connell, Chief Business Officer of Fortem Technologiesю
Fortem's SkyDome Family of Systems is built around detection, classification and interception. TrueView radar sensors scan surrounding airspace and track small aircraft, while SkyDome Manager software combines the information and helps operators identify possible threats.
DroneHunter provides the interception part of the system. The autonomous aircraft is designed to pursue another drone and remove it from the air.
The system can be installed permanently or used as part of a mobile setup, depending on the site and operational requirements. Fortem serves military bases, airports, energy infrastructure, prisons, public venues and other locations where controlled airspace needs protection.
Lockheed Martin led Fortem's $50 million Series B after committing $25 million in the initial tranche. Unusual Machines also participated in the round, together with other strategic and institutional investors.
Fortem has previously received backing from investors including DCVC, Toshiba, AIM13 and Signia Venture Partners. Toshiba invested $15 million in 2021.
In 2023, Fortem raised another $17.8 million in a round that included Lockheed Martin Ventures, Hanwha Aerospace and AIM13|Crumpton Venture Partners as new investors, alongside existing investors DCVC and Signia Venture Partners.
