Fortem closes $50M Series B to scale counter-drone systems

Fortem Technologies has closed a $50 million Series B led by Lockheed Martin to expand an integrated counter-drone system for military, government and commercial security teams. Its SkyDome product family combines ground-based sensors, command software and autonomous DroneHunter interceptors rather than treating detection and defeat as separate products.

Fortem’s product materials describe a workflow that begins with radar, cameras and radio-frequency sensors feeding tracks into SkyDome Manager. The software filters out irrelevant objects, classifies potential drones and ranks threats using factors such as speed and direction. An operator can review visual evidence, authorize a response and stop or recall an interceptor after launch.

For a serious threat, DroneHunter uses its own radar to pursue the target and fires an expanding net. Smaller drones can be carried to a designated location, while a net and drogue can slow larger targets into a controlled descent. That physical catch-and-remove approach doesn’t depend on the target maintaining a radio link that can be jammed.

Lockheed Martin supplied $25 million through the initial tranche announced in April, or half of the completed round. Unusual Machines and other investors also participated. Fortem said the capital will increase manufacturing at its Lindon, Utah, facility and widen deployments; Lockheed is also integrating the company’s technology into its broader Sanctum counter-drone architecture.

Fortem has announced contracts to protect 2026 FIFA World Cup venues for the Department of Homeland Security and defend United States Army installations. In August, the company separately said it was one of seven Track 1 prime contractors eligible to receive Homeland Security task orders. The vehicle’s estimated $1.011 billion starting ceiling covers the multiple-award program, not booked Fortem revenue.
