The Royal Navy operates a fleet of submarines that play a crucial role in national defense and maritime security. These submarines are designed for various missions, including surveillance, reconnaissance, and deterrence. The most advanced class, the Astute-class, features cutting-edge technology and stealth capabilities, allowing them to operate undetected. Royal Navy submarines are equipped with nuclear propulsion, enabling them to remain submerged for extended periods without surfacing. They carry a range of weapons, including Tomahawk cruise missiles, which can strike targets on land or at sea. This versatility makes them a vital component of the UK's military strategy.
