The U.S. Department of Defense has taken an unprecedented step to modernize its submarine fleet. The Pentagon has signed a series of contracts totaling more than $76 billion, which will fund the construction of 14 new nuclear-powered submarines. This massive fleet upgrade is planned to be implemented during the fiscal years 2025 through 2029.
Two Industry Giants and New Submarines
According to the U.S. Navy, government orders have been distributed between the country's two leading shipbuilding companies. The defense industry giant General Dynamics Electric Boat received the contract to build five Columbia-class ballistic missile submarines.
The second major contract went to HII-Newport News Shipbuilding. They are set to build nine Virginia-class multi-purpose nuclear submarines. These vessels are designed to provide powerful strike capabilities and are capable of carrying a significant payload.
Strategic Significance and Priorities
The Pentagon characterizes these deals as "historic investments" in the future of U.S. naval power. Special attention is being paid to the Columbia-class submarines, which, according to military officials, will become the most survivable component of the nation's nuclear triad. Equipped with ballistic missiles, they are intended to ensure effective strategic deterrence and remain the number one priority in Department of Defense procurement.
Parallel to this, the deployment of advanced Virginia-class platforms is being supported, which play a key role in tactical and strike operations.
Program Scale and Generation Change
The new contracts complement existing plans. As of 2026, the U.S. Navy already has contracts for seven Columbia-class submarines. As for the Virginia class, the fleet currently has 26 submarines of this type built, with another 23 planned for construction.
Fleet modernization also implies the decommissioning of aging units. In the near future, the United States will retire Ohio-class submarines. These vessels, capable of carrying up to 154 Tomahawk cruise missiles, are renowned for their unique endurance. They can perform continuous missions lasting about two years. In naval history, there is a case where the submarine USS Florida, during a 700-day combat patrol, covered about 100,000 kilometers, demonstrating phenomenal autonomy characteristics.
