The Royal Navy’s Astute class designed by BAE Systems Maritime and the US Navy’s Virginiaclass built by General Dynamics Electric Boat and Newport News Shipbuilding. Both are among the best nuclear-powered attack submarine (SSN) classes in the world. We put them head-to-head in the ring on factors like size, speed, armament, technology and cost.
The Royal Navy’s Astute-class SSN is currently the tenth-biggest submarine class in the world, with a surfaced displacement of 7,000t to 7,400t, and a submerged displacement of 7,400t to 7,800t. At a length of 97m (318ft 3in) and a beam of 11.3m (37ft 1in), the Astute class is smaller than US Navy’s Virginiaclass. The Virginia class has a displacem...
The Astute is powered by the latest Rolls-Roycepressurised water reactor (PWR 2) design, the Core H, which eliminates the need for refuelling, and means that the sub’s nuclear reactor only requires one refit instead of the traditional two refits throughout its service life. Astutehas unlimited endurance and can provide unlimited air and water suppl...
Being attack submarines, both classes are naturally armed to the teeth with the latest maritime weaponry. Astute-class submarines come with six 21 in torpedo tubes capable of firing Spearfish heavyweight torpedoes. It also launches Raytheon Tomahawk Block IV cruise missiles for land-attack operations, upgraded to the Block V from 2024. The Astutecl...
