Construction starts on UK's biggest, most advanced nuclear submarine

Construction has commenced on the UK’s most advanced nuclear-powered attack submarine, the SSN-AUKUS, marking a significant step in the nation’s defense capabilities under the AUKUS partnership with Australia and the US. The London-based defense firm Babcock has secured key contracts to build components for this new class of conventionally-armed submarines, which are set to replace the current Astute-class vessels starting in the late 2030s. The program envisions building up to 12 SSN-AUKUS submarines, representing a major expansion of the UK’s submarine fleet and industrial capacity, particularly at the Barrow and Raynesway shipyards. Babcock’s involvement includes delivering weapon handling and launch systems, integrated tube hulls, and technical support for the Tomahawk missile, leveraging its extensive experience in submarine manufacturing and integration. The program aligns with a broader £15 billion government investment in the UK’s sovereign warhead program and aims to enhance Britain’s deterrence and defense
