The Submarine Service is the [[submarine]] based element of the Royal Navy. It is sometimes referred to as the "''Silent Service''",<ref>{{cite web|url=http://www.royalnavy.mod.uk/The-Fleet/Shore-Establishments/HMS-Raleigh/Royal-Navy-Submarine-School |title=Royal Navy Submarine School |publisher=Royal Navy |date=10 April 2012 |access-date=2 March 2016 |archive-url=https://web.archive.org/web/20120419073443/http://www.royalnavy.mod.uk/The-Fleet/Shore-Establishments/HMS-Raleigh/Royal-Navy-Submarine-School |archive-date=19 April 2012 }}</ref> as the submarines are generally required to operate undetected. Founded in 1901, the service made history in 1982 when, during the Falklands War, {{HMS|Conqueror|S48|6}} became the first nuclear-powered submarine to sink a surface ship, {{ship|ARA|General Belgrano}}. Today, all of the Royal Navy's submarines are [[Nuclear marine propulsion|nuclear-powered]].<ref>{{cite web|url=https://www.royalnavy.mod.uk/news-and-latest-activity/news/2013/february/13/130213-submarine-propulsion|title=MOD Awards £800m Contract For Submarine Propulsion Programme|date=13 February 2013|publisher=Royal Navy|access-date=30 December 2017|archive-url=https://web.archive.org/web/20171230230222/https://www.royalnavy.mod.uk/news-and-latest-activity/news/2013/february/13/130213-submarine-propulsion|archive-date=30 December 2017|url-status=live}}</ref>

====Ballistic missile submarines (SSBN)====
The Royal Navy operates four {{sclass|Vanguard|submarine|0}} [[ballistic missile submarine]]s displacing nearly 16,000 tonnes and equipped with Trident II missiles (armed with [[Nuclear weapons and the United Kingdom|nuclear weapons]]) and heavyweight [[Spearfish torpedo]]es, to carry out Operation Relentless, the United Kingdom's Continuous At Sea Deterrent (CASD). The UK government has committed to replace these submarines with four new {{sclass|Dreadnought|submarine|1}}s, which will enter service in the "early 2030s" to maintain this capability.<ref name="theyworkforyou1">{{cite web|author=a few days |url=https://www.theyworkforyou.com/wrans/?id=2020-01-30.10350.h&s=c |title=HMS Audacious: 6 Feb 2020: Hansard Written Answers |publisher=TheyWorkForYou |date=6 February 2020 |access-date=12 May 2020}}</ref><ref>{{Cite news |url=https://www.newscientist.com/article/dn10729 |title=UK unveils plans for a new submarine fleet |publisher=New Scientist (Environment) |last=Knight |first=Will |date=5 December 2006 |access-date=10 August 2007 |archive-url=https://web.archive.org/web/20081208162915/http://www.newscientist.com/article/dn10729 |archive-date=8 December 2008 |url-status=live  }}</ref>
