L3Harris Technologies has integrated its VAMPIRE counter-unmanned aerial system onto GM Defense’s Infantry Squad Vehicle (ISV), creating a mobile counter-drone solution for U.S. Army operations.

The VAMPIRE (Vehicle-Agnostic Modular Palletized ISR Rocket Equipment) platform provides reconnaissance and precision-strike capabilities against small drones and remotely piloted aircraft. The system has been deployed in European conflict zones since 2023, where it has reportedly neutralized hundreds of unmanned aerial threats.

“Deploying VAMPIRE on GM Defense’s ISV is a great example of how quickly and seamlessly this system can be used by our Army customer to defeat the rapidly growing threat of small, hostile drones,” said Tom Kirkland, Vice President and General Manager of Targeting and Sensor Systems at L3Harris. “Working together, we have swiftly responded to the urgent need to defeat small unmanned autonomous systems accurately and affordably while allowing ground forces to stay tactically mobile.”

The GM Defense ISV was designed to meet the U.S. Army’s requirement for a lightweight, rapidly deployable off-road vehicle capable of supporting a nine-soldier squad. Built on a commercial Chevrolet Colorado ZR2 chassis, the ISV is engineered for adaptability and low maintenance across diverse mission types.

By mounting VAMPIRE on the ISV, GM Defense and L3Harris aim to deliver a modular, easily deployable counter-UAS capability. The partnership reflects ongoing efforts to expand the ISV’s functionality through specialized kits for different mission profiles.

“The versatility of the ISV is one of its core strengths, and integrating a critical counter-UAS capability like VAMPIRE showcases our ability to rapidly adapt the vehicle to meet evolving threats,” said John “JD” Johnson, Vice President of Government Solutions and Strategy at GM Defense. “This successful integration highlights how the ISV's modular design and commercial-based architecture can quickly incorporate next-generation technologies to deliver immediate value and enhanced protection to our warfighters.”

The demonstration underscores a broader U.S. Army push toward mobile, cost-effective systems capable of countering the expanding threat of small drones in modern battlefields.
