HMS Agamemnon is the sixth Astute-class nuclear-powered fleet submarine of the Royal Navy and is currently under construction. She will be the sixth vessel of the Royal Navy to bear the name, after the legendary Greek king Agamemnon.

On 25 March 2010, BAE Systems were given the go-ahead by the 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. [9] Initial construction work was begun on boat 6 late in 2010 and is ongoing as of 2011. [10] On 15 September 2011 it was announced that boat 5 was to be named Anson; it had previously been stated that boat 5 (as S123) would be Agamemnon and boat 6 Anson, and it is now believed that the Agamemnon name will be transferred to boat 6.[ citation needed ]

Her keel was laid on 18 July 2013, when the Minister for Defence Equipment, Support and Technology, Philip Dunne, unveiled the "Agamemnon Keel Unit". [11]

Her electric switchboards were powered up, for the first time, 1 October 2020, making the boat go "live". [12]

Design

Propulsion

Agamemnon's nuclear reactor will not need to be refueled 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

Agamemnon will have provision for up-to 38 weapons in six 21-inch (533 mm) torpedo tubes. [13] The submarine will be capable of using Tomahawk Block IV land-attack missiles with a range of 1,000 miles (1,600 kilometres) [14] and Spearfish heavyweight torpedoes.

<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 The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.

<i>Vanguard</i>-class submarine Royal Navy ballistic missile submarine class

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.

<i>Astute</i>-class submarine Class of nuclear-powered fleet submarines

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.

The Spearfish torpedo is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo.

HMS Artful is the third Astute-class nuclear-powered fleet submarine of the British Royal Navy. She is the second submarine of the Royal Navy to bear this name. 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 commissioned on 14 February 1978, by Lady Audrey White. She was the tenth nuclear fleet submarine to enter service with the Royal Navy. 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.
