Serco, a provider of professional, technology, and management services, completed the acquisition of Alion's Naval Systems Business Unit, a provider of naval ship and submarine design, systems and engineering services, production support and in-service sustainment for $225m. The acquisition would substantially strengthen Serco's presence in naval support, modernization and sustainment, which has been a key growth area for the Company in recent years. "Combining our existing C5ISR capabilities in ship, shore, satellite and radar modernization with the naval design and engineering capabilities of NSBU will make Serco a top-tier Navy services provider with a full-spectrum, design-integrate-support life cycle maritime offering," Dave Dacquino, Serco CEO.
