Alion
Alion's Overview
Alion Science and Technology, acquired by Huntington Ingalls Industries (HII) in August 2021, was a prominent provider of advanced engineering, research and development, and operational solutions. For nearly two decades, Alion supported the U.S. Department of Defense, the intelligence community, and other federal agencies by delivering critical expertise in areas such as C5ISR (Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance), artificial intelligence, big data, cyber security, electronic warfare, and live, virtual, and constructive (LVC) training. Following its acquisition, Alion's capabilities and personnel were integrated into HII's Technical Solutions division, which was subsequently rebranded as HII Mission Technologies. This integration significantly enhanced HII's portfolio in high-growth national security markets, strengthening its offerings in advanced mission solutions.
