RN Ships & Subs - P to S

The Royal Navy's active fleet of major warships and submarines forms a technologically advanced but numerically limited force focused on high-end capabilities, including carrier strike, air defense, anti-submarine warfare, and strategic nuclear deterrence. The surface fleet is centered on two Queen Elizabeth-class aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, which provide global power projection with F-35B Lightning jets and serve as flagships for carrier strike groups. These are supported by six Type 45 guided-missile destroyers—specialized in anti-air warfare with the Sea Viper system—and approximately seven Type 23 frigates, versatile platforms handling anti-submarine and general-purpose roles as they are gradually phased out. The submarine service includes four Vanguard-class ballistic missile submarines maintaining the UK's continuous at-sea nuclear deterrent and six Astute-class nuclear-powered fleet submarines (with the seventh nearing completion), renowned for their stealth, endurance, and multi-role capabilities armed with Spearfish torpedoes and Tomahawk missiles. This fleet, complemented by mine countermeasures vessels, patrol ships, and auxiliaries, enables the Royal Navy to conduct operations worldwide, from NATO commitments in the North Atlantic to maritime security, though ongoing transitions to new Type 26 and Type 31 frigates highlight efforts to modernize amid evolving threats.
