CACI to Acquire Space Technology Firm ARKA for $2.6 Billion, Expanding National Security Capabilities
December 22, 2025 — Washington, D.C. — CACI International, a leading defense and intelligence contractor, announced on December 22, 2025, its intention to acquire ARKA Group, a prominent space technology company, in an all-cash deal valued at approximately $2.6 billion. This strategic move significantly broadens CACI’s presence in space-based sensing and intelligence systems.
Expanding Footprint in Space-Based Intelligence
Headquartered in Reston, Virginia, CACI is a publicly traded company specializing in defense, intelligence, and national security solutions. The ARKA Group, based in Danbury, Connecticut, is well-known for its advanced software and hardware solutions related to space-based sensors. ARKA develops sophisticated software tools for processing and analyzing data derived from radar and remote sensing satellites. Its portfolio encompasses analytics and data fusion capabilities that transform raw sensor information into actionable intelligence.
Furthermore, ARKA produces space-qualified optical payloads and subsystems, including high-precision telescopes and electro-optical sensors. These technologies support critical intelligence, surveillance, and reconnaissance (ISR) missions by enhancing remote sensing and intelligence gathering from space platforms. The company has recently expanded its manufacturing facilities to bolster its capacity for producing payloads and optical coatings.
Ownership Background and Strategic Alignment
ARKA has been part of Blackstone Tactical Opportunities, the private equity investment arm of Blackstone, since 2019. Throughout its ownership, Blackstone facilitated ARKA’s growth through various acquisitions. CACI’s acquisition of ARKA represents a step to deepen its engagement in the space domain, particularly in support of U.S. national security missions.
“ARKA supports national security missions through its space-based sensor portfolio and ground-based software processing, accelerating the delivery of actionable intelligence to the warfighter,” CACI stated. John Mengucci, President and CEO of CACI, described the acquisition as “a significant step forward in our space strategy,” highlighting that it positions the company to “capture significant future opportunities in the space domain across the intelligence community, U.S. Space Force, and other Department of Defense customers.”
Complementing CACI’s Existing Space Capabilities
CACI’s space-related business spans hardware development, software innovation, and professional services. One of its notable product lines includes optical communications terminals, which enable high-speed satellite-to-satellite data transmission for U.S. government customers.
In addition, CACI recently secured a 10-year contract valued at up to $450 million to support the Joint Navigation Warfare Center, an entity under U.S. Space Command tasked with safeguarding satellite-based positioning, navigation, and timing capabilities vital to defense operations.
Next Steps and Closing Timeline
The acquisition agreement is subject to regulatory approvals and customary closing conditions. CACI anticipates finalizing the transaction in the third quarter of its fiscal year 2026. This acquisition underscores the intensifying focus of defense contractors on space technologies, particularly those enhancing situational awareness and intelligence for national security. By integrating ARKA’s technologies and expertise, CACI aims to enhance its capabilities in space-based sensing, data analytics, and optical communications, thereby strengthening the United States’ space defense infrastructure.
