The Astute-class submarines have set new standards for the Royal Navy’s underwater warfare capabilities. These nuclear-powered vessels feature some of the most advanced sonar systems ever deployed, capable of tracking ships departing New York Harbor while the submarine remains submerged near the English Channel. The submarine’s nuclear reactor provides virtually unlimited range, requiring no refueling over its 25-year service life. Armed with Spearfish torpedoes and Tomahawk land-attack missiles, the Astute-class is equipped with a state-of-the-art combat management system that enables precise target tracking and engagement in challenging environments. Its unique hull design and acoustic-dampening tiles make it one of the stealthiest submarines ever built.
