The Dreadnought-class submarines are a series of nuclear-powered submarines used by the Royal Navy of the United Kingdom. They are designed to carry and launch Trident II ballistic missiles, providing a key component of the UK's nuclear deterrent strategy. These submarines are known for their stealth capabilities and advanced technology, allowing them to operate undetected in various maritime environments. Each Dreadnought-class submarine is equipped with modern systems for navigation, communication, and combat, ensuring they can perform effectively in diverse missions. The class is set to replace the older Vanguard-class submarines, with the first of the new class expected to enter service in the mid-2020s.
