TL;DR
HII announced it has received government contracts to construct Block VI Virginia-class and Build I Columbia-class submarines. This development confirms the company’s role in advancing U.S. naval submarine programs, with implications for national security and defense industry supply chains.
HII has been awarded contracts to build Block VI Virginia-class and Build I Columbia-class submarines, marking a major step in U.S. naval modernization efforts. This confirms the company’s continued role in producing critical submarine platforms for the U.S. Navy, with broad implications for national security and defense manufacturing.
The Department of Defense announced on March 2024 that HII received contracts worth hundreds of millions of dollars to construct multiple submarines. Specifically, the company will build Block VI Virginia-class submarines, which are the latest iteration of the Navy’s nuclear-powered attack submarines, and Build I Columbia-class submarines, the next-generation ballistic missile submarines designed to replace the Ohio-class fleet.
These contracts are part of the Navy’s ongoing efforts to modernize its submarine fleet. The Virginia-class program is managed by HII’s Newport News Shipbuilding division, while the Columbia-class program is a collaboration with General Dynamics Electric Boat. The awards include both initial construction and future sustainment work, emphasizing HII’s critical role in maintaining U.S. naval superiority.
Officials from HII and the Department of Defense confirmed the awards, with HII stating that the contracts will support hundreds of jobs and reinforce the company’s position as a leader in submarine construction. The exact dollar amounts and specific project timelines remain undisclosed at this stage.
Strategic Implications of New Submarine Contracts
The awarding of these contracts underscores the U.S. Navy’s focus on maintaining a modern, capable submarine fleet amid rising global maritime tensions. The Virginia-class and Columbia-class submarines are essential components of national defense, providing strategic deterrence and underwater warfare capabilities. For HII, this solidifies its role as a key contractor in the U.S. military industrial complex, supporting thousands of jobs and technological innovation.
Furthermore, these contracts signal continued investment in submarine technology and production capacity, which are vital for the U.S. to sustain its naval dominance for decades to come. The projects also highlight ongoing collaboration between government and industry, with implications for future defense procurement and industrial base resilience.

Background on Virginia-class and Columbia-class Programs
The Virginia-class submarine program began in the early 2000s to replace aging attack submarines, with the latest Block VI being part of a series that emphasizes technological upgrades and extended service life. Construction of Virginia-class submarines is managed by HII’s Newport News Shipbuilding, which has delivered multiple units since the program’s inception.
The Columbia-class program, initiated in the 2010s, aims to replace the Ohio-class ballistic missile submarines, ensuring nuclear deterrence capabilities through the 2080s. This program involves extensive collaboration between HII and General Dynamics Electric Boat, with the first units expected to be delivered in the late 2020s.
These programs are among the largest and most complex naval shipbuilding efforts in U.S. history, with significant funding allocated annually to sustain production and technological development.
“This contract award affirms HII’s leadership in submarine construction and our critical role in supporting the Navy’s modernization goals.”
