Company History and Business Evolution

Founded in 2002 as a spin-off from IIT Research Institute (IITRI), Alion Science and Technology Corporation was established to focus on advanced technology solutions for defense and national security. The company quickly gained momentum through strategic acquisitions and organic growth, expanding its capabilities in cyber warfare, sensor systems, and decision support tools. A significant milestone came in 2007 when Alion acquired the Science and Technology Business of IITRI, solidifying its position in the research and development arena. Over the next decade, the company continued to broaden its portfolio, adding expertise in electronic warfare through the acquisition of Ticom Geomatics and others. In 2021, Alion was acquired by Huntington Ingalls Industries (HII) for $1.65 billion, marking a new chapter as an independent operating division within HII's Technical Solutions segment. Despite the ownership change, the Alion brand and mission remain intact, continuing to deliver cutting-edge capabilities to warfighters and government clients. This evolution underscores the company's resilience and adaptability in a rapidly changing defense landscape.
