History

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. On 15 September 2011 it was announced that boat 5 would be named Anson; [9] it was previously believed that boat 5 would be Agamemnon and boat 6 Anson. Her keel was ceremonially laid on 13 October 2011. [10] [11] On 19 November 2015, a possible new contract worth £1.3 billion was signed for HMS Anson. [12] She was officially named on 11 December 2020, [13] [14] was rolled out of the Devonshire Dock Hall on 19 April 2021, [15] and launched on 20 April 2021. [16] It completed its first practice dive in a dock on 14 February 2022. [17] She was commissioned on 31 August 2022 prior to starting sea trials. [18] [19] On 19 February 2023 she left Barrow for the first time for her sea trials. [20]

Design

Propulsion

Anson's nuclear reactor will not need to be refuelled during the boat's 25-year service. Since the submarine can purify water and air, she will be able to circumnavigate the planet without resurfacing. The main limit is that the submarine will only be able to carry three months' supply of food for 98 officers and ratings.

Weapons

Anson will have provision for up to 38 weapons in six 21-inch (533 mm) torpedo tubes. [21] The submarine will be capable of using Tomahawk Block IV land-attack missiles with a range of 1,000 miles (1,600 kilometres) [22] and Spearfish heavyweight torpedoes.

The Swiftsure class was a class of nuclear-powered fleet submarines in service with the Royal Navy from the early 1970s until 2010.

<i>Trafalgar</i>-class submarine 1983 class of British attack submarines

The Trafalgar class is a class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy, and the successor to the Swiftsure class. Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. With only one boat remaining active and in commission and six retired from the seven originally in service, the class makes up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.

The Vanguard class is a class of nuclear-powered ballistic missile submarines (SSBNs) in service with the Royal Navy. The class was introduced in 1994 as part of the Trident nuclear programme, and comprises four vessels: Vanguard, Victorious, Vigilant and Vengeance, built between 1986 and 1999 at Barrow-in-Furness by Vickers Shipbuilding and Engineering, now owned by BAE Systems. All four boats are based at HM Naval Base Clyde , 40 km (25 mi) west of Glasgow, Scotland.

The Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The boats are being constructed by BAE Systems Submarines at Barrow-in-Furness. Seven boats will be constructed: the first of class, Astute, was launched by Queen Camilla, in 2007, commissioned in 2010, and declared fully operational in May 2014. The Astute class is the replacement for the Trafalgar-class fleet submarines in Royal Navy service.

Artful was ordered from GEC's Marconi Marine on 17 March 1997, and was constructed at Barrow in Furness. She was named on 20 September 2013, was rolled out of the shipyard construction hall on 16 May 2014, and was due to start sea trials in early 2015. Artful made her first successful basin dive in October 2014, and sailed on 13 August 2015 for sea trials. Artful was handed over the Royal Navy on 14 December 2015, and commissioned on 18 March 2016.

The fifth HMS Sceptre is a Swiftsure-class submarine built by Vickers in Barrow-in-Furness. She was launched in 1976, with a bottle of cider against her hull.

She was decommissioned on 10 December 2010, at which time she was the oldest commissioned vessel in the Royal Navy still available for service; in total around 1,500 men served aboard during her commission. In theory, she is replaced by the first Astute-class submarine in service, HMS Astute.
