CACI International Inc
"Ever Vigilant"
CACI International is a Reston, Virginia defense contractor whose SkyValor counter-drone system won a $500M JIATF-401 contract in 2026.
CACI International Inc is a Reston, Virginia-headquartered technology and expertise provider to U.S. federal government agencies, with a business built around national security, intelligence, and defense modernization work. The company traces its roots to 1962, when Herb Karr and Harry Markowitz left the RAND Corporation to commercialize the SIMSCRIPT simulation programming language, initially operating as California Analysis Center, Inc. before adopting the CACI name in 1973. Publicly traded on the New York Stock Exchange under the ticker CACI, the company today employs roughly 24,000 people and has grown through decades of acquisitions, including L-3 National Security Solutions in 2015, into a diversified provider of C4ISR, cyber, software, and network modernization services for the Department of Defense, homeland security, and intelligence community customers.
Within CACI's portfolio is SkyValor, a counter-unmanned aircraft systems platform designed to detect, track, and defeat hostile drones using RF-based sensing and mitigation techniques. In August 2026, CACI was awarded a contract worth approximately 500 million dollars to supply the SkyValor system to Joint Interagency Task Force 401, extending the company's presence in the fast-growing counter-drone defense segment alongside its existing work in electronic warfare, optical communications, and signal intelligence.
Beyond counter-drone systems, CACI's business spans agile software development for government platforms, cybersecurity operations, network modernization, mission and engineering support, and enterprise IT services delivered under long-running federal contract vehicles. Its customer base is concentrated almost entirely in the U.S. government sector, particularly the Department of Defense and national intelligence agencies, distinguishing it from commercial robotics and drone vendors that primarily serve industrial or consumer markets.
CACI operates its Reston headquarters at 12021 Sunset Hills Road, a facility the company opened in 2021 to consolidate its regional workforce. The company markets itself under the motto Ever Vigilant, reflecting its focus on national security missions. As a systems integrator rather than a component or airframe manufacturer, CACI typically partners with hardware suppliers and integrates sensors, communications links, and software into mission-ready systems for government end users, a role that positions SkyValor and related counter-drone offerings as software and integration heavy rather than a purely hardware product line.
