These submarines can also be fitted with a dry deck shelter, which allows special forces (e.g. SBS) to deploy whilst the submarine is submerged. [33] More than 39,000 acoustic tiles mask the vessel's sonar signature, part of acoustic qualities that give the Astute class over any other submarine previously operated by the Royal Navy.

Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. The class made up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class was replaced by the larger and more capable Astute class, of which five are commissioned.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". [ 1 ]
The Astute-class submarine is the largest nuclear fleet submarine ever to serve with the Royal Navy, being nearly 30% larger than its predecessors. Its powerplant is the Rolls-Royce PWR2 reactor, developed for the Vanguard-class SSBN. The submarine's armament consists of up to 38 Spearfish torpedoes and Tomahawk Block IV land-attack cruise ...
The R-class submarine was designed to meet an Admiralty requirement for a specialised hunter-killer submarine with an emphasis on submerged performance. The boats had a length of 163 feet 9 inches (49.9 m) overall, a beam of 15 feet 3 inches (4.6 m) and a mean draft of 11 feet 6 inches (3.5 m).
A hunter-killer group would typically be formed around an escort carrier to provide aerial reconnaissance and air cover, with a number of corvettes, destroyers, destroyer escorts, frigates, and/or United States Coast Guard Cutters armed with depth charges and Hedgehog anti-submarine mortars.
On 25 March 2010, BAE Systems were given the authorisation by the British government to begin construction on boats 5 and 6 (Anson and Agamemnon), being given a £300 million contract for the "initial build" of boat 5 and "long lead procurement activities" for boat 6. [8] Later that year work was begun on the pressure hull and reactor compartments.
