The Astute-class submarines are a class of nuclear-powered submarines used by the Royal Navy of the United Kingdom. Designed for a variety of missions, they are capable of anti-submarine warfare, anti-surface ship warfare, and intelligence gathering. The submarines are known for their advanced stealth features, allowing them to operate undetected in hostile environments. Each Astute-class submarine is equipped with state-of-the-art technology, including a sophisticated sonar system and advanced weaponry. They can carry a range of missiles, including Tomahawk cruise missiles, making them versatile assets in modern naval operations. The class is designed to replace the older Swiftsure-class submarines.
