Virginia-class
The US Navy’s premier nuclear-powered fast-attack submarine, blending advanced quieting, a large Tomahawk strike payload, and special-operations support; the platform at the center of the AUKUS submarine pathway.
The United States Navy’s front-line nuclear fast-attack submarine, in serial production since 2004, combining advanced quieting, a growing Tomahawk land-attack punch, and a lock-out chamber for special forces — the boat that will underpin Australia’s nuclear-powered submarine force under AUKUS.
Overview
The Virginia class (SSN-774) is the United States Navy’s premier nuclear-powered attack submarine, designed for multi-mission dominance across open-ocean and littoral environments. Built by a teaming arrangement between General Dynamics Electric Boat and HII Newport News, each boat integrates long-endurance ASW, anti-surface warfare, land-attack, intelligence-surveillance-reconnaissance, and special-operations support. Approximately 24 hulls have been commissioned, and serial production continues through Block V and beyond. The class is equally the cornerstone of the AUKUS Pillar I agreement, under which Australia will acquire its first nuclear-powered submarines from the early 2030s.
Development
The Virginia class originated as the New Attack Submarine (NSSN) in the 1990s, conceived as a more affordable, more versatile successor to the Seawolf class. The lead boat, USS Virginia (SSN-774), was commissioned in 2004, as detailed in the US Navy’s Attack Submarines fact file. Production evolved through successive blocks that introduced modular construction, improved sensors, and reduced lifecycle maintenance costs. The defining shift arrived with Block V, which introduces the Virginia Payload Module (VPM) — an 84-foot hull insert that quadruples the boat’s Tomahawk capacity. Construction of the first Block V boat reached a key milestone in December 2025, with delivery expected early next decade, according to Naval Today.
