The contract, worth as much as $542 million, was issued by the Naval Sea Systems Command and services such as engineering, logistics, program management and business and financial management for Team Submarine Program Offices.
Included is support for the acquisition, development, and maintenance of submarines, sensors, combat systems and weapons.
Team Submarine brings together all submarine-related organizations in the Navy and focuses on undersea warfare research, development and acquisition.
"The U.S. undersea forces are crucial to the nation's security strategy," said Alion Senior Vice President Rod Riddick. "Alion's experts have been supporting the submarine force for decades, so we fully understand the environment in which they operate. This means we can implement solutions that can make the undersea fleet faster, quieter, safer and more powerful, while meeting the Navy's financial goals."
The contract is for five years.
