HII Deepens Partnership with Babcock International Group in Support of Virginia-Class Submarine Construction
ARLINGTON, Va., Dec. 09, 2025 (GLOBE NEWSWIRE) -- HII (NYSE: HII) and Babcock International Group (Babcock) announced today they have signed a contract that expands their strategic partnership to further support Virginia-class submarine construction throughput at HII’s Newport News Shipbuilding (NNS) division. Additionally, the contract will build resiliency within HII’s submarine supply base.
