BlueHalo on Monday said it has acquired Verus Technology Group, a small company that provides counter-unmanned aircraft system (C-UAS) products based on radio frequency and digital signal processing technologies.

Terms of the deal were not disclosed.

Verus, which is based in Northern Virginia, develops and produces the SkyView family of passive RF-based detection, identification, tracking and telemetry extraction of small UAS. SkyView is offered in mobile and fixed-site solutions for military and critical infrastructure applications.

Verus has delivered more than 400 C-UAS sensors to various customers through the Defense Department, intelligence community, civilian, commercial and international customers. The company’s products are also on two programs of record with the Marine Corps and Special Operations Command.

BlueHalo, a portfolio company of Arlington Capital Partners, already offers the artificial intelligence and machine learning-enabled RF-based Titan C-UAS solution, which is used by U.S. Customs and Border Protection, the Locust directed energy C-UAS solution, and the ARGUS perimeter security system for physical security.

“Drone technology continues to proliferate, allowing bad actors to acquire greater capability at a lower cost,” David Wodlinger, a managing partner at Arlington Capital, said in a statement. “The U.S., and the world more broadly, are not yet adequately prepared for the threat that drones pose to our critical infrastructure and national security. Within BlueHalo, we plan to invest an increasing amount of resources into bringing to market the best C-UAS solutions to address these emerging threats.”

Jonathan Moneymaker, BlueHalo’s CEO, said acquiring Verus will allow the company to “provide an integrated…set of solutions offering a protective ring around our customers as we seek to neutralize the ongoing C-UAS threat.”

Citizens Capital Markets was Verus’ financial adviser on the transaction.
