Amentum
US defense & engineering firm spun off from AECOM in 2020; ~50,000 employees across 80 countries supporting nuclear, space, and military programs.
Amentum is a Chantilly, Virginia-headquartered global engineering and technical services company established in 2020 as an independent spinoff following the sale of AECOM's Management Services division to private equity firms American Securities and Lindsay Goldberg for $2.4 billion. The company provides engineering, operations, logistics, and technical solutions primarily to the U.S. federal government and allied nations, with a particular concentration in the Department of Defense and the Department of Energy.
Amentum operates through two primary business segments — digital services and global engineering — and employs approximately 50,000 people in more than 80 countries across all seven continents. As of fiscal year 2025 the company reported revenue of approximately $14.4 billion and a total contract backlog of $47.1 billion.
Core capability areas include defense support services (aviation maintenance for U.S. Army, Navy, Air Force, and Department of Homeland Security across more than 200 aircraft models), nuclear security and environmental remediation, space systems engineering, maritime systems integration (hull design, propulsion, combat systems), intelligence and cybersecurity, and advanced technical facility design and construction. Special operations support and research, development, test, and evaluation (RDT&E) services constitute additional focus areas.
In the robotics and automation context, Amentum deploys robotic and autonomous systems for inspection, maintenance, and hazardous-environment operations — including nuclear facilities, remote military installations, and space-relevant test environments. The company manages programs involving unmanned systems, autonomous ground vehicles, and robotic manipulation tools used in special operations and extreme environmental conditions.
Amentum became a publicly listed company in 2024 (NYSE: AMTM) following a merger with Jacobs Solutions' Critical Mission Solutions segment, significantly expanding its scale. The company's corporate headquarters is located at 4800 Westfields Blvd, Suite 400, Chantilly, Virginia.
