CACI International Inc (NYSE: CACI) today announced the Spectral program has successfully completed rigorous review by the U.S. Navy’s Program Executive Office for Command, Control, Communications, Computers, and Intelligence (PEO C4I), achieving Milestone C. CACI partnered with PEO C4I’s Program Manager Warfare Battlespace Awareness and Information Operations Program Office (PMW 120), to achieve this historic accomplishment, marking the start of the program's low-rate initial production (LRIP) and deployment phase, a defining step toward placing this critical electronic warfare (EW) technology in the hands of U.S. sailors.

“This recent milestone enables the delivery of modern, cutting-edge technologies that empower our warfighters to defend the nation from our adversaries and maintain decision superiority across every domain, especially the electromagnetic spectrum,” said John Mengucci, CACI President and CEO. “Our bold investments in technology and our world-class engineering team have led us to this critical milestone, a momentous leap forward for the Navy. I thank the Navy for entrusting CACI to strengthen their ability to defend the nation and prevail in contested environments, when it matters most – when the stakes are highest, and lives are on the line.”

As part of Milestone C, CACI and PMW 120 have executed several Iterative Capability Tests proving the functionality of the system which led to this decision by Milestone Defense Authority. Under the Spectral program, CACI will rapidly, and at scale, develop and deploy the next generation of shipboard signals intelligence and electronic warfare capabilities, effectively protecting warfighters from electronic attacks and adversarial threats.

Through software-defined systems and open architectures, CACI optimizes platforms with advanced electromagnetic warfare technologies that detect and exploit signals across the spectrum — enabling sensing, communications, and information operations.
