The Royal Navy currently has nine nuclear-powered submarines in service, including four nuclear-armed vessels maintaining the UK’s continuous at-sea deterrent, the Ministry of Defence has confirmed.
Responding to a question in the House of Lords, Defence Minister Lord Coaker said the submarine force consists of four Vanguard-class ballistic missile submarines and five Astute-class attack submarines.
“The Royal Navy has a fleet of nine submarines currently in service,” he told peers. “It operates four Vanguard class nuclear-powered and nuclear-armed submarines in Operation Relentless, the continuous at-sea deterrent, which has been successfully maintained for over 56 years.”
Lord Coaker added that the Vanguard-class boats will be replaced by four Dreadnought-class submarines, which are scheduled to enter service in the 2030s. He also confirmed that two additional Astute-class submarines are currently under construction. The exchange followed a question from Lord Trefgarne, who asked how many nuclear-powered and nuclear-armed submarines are currently in service. In a follow-up, he asked whether the deterrent submarines are being maintained and operated to the required standard.
In response, Lord Coaker emphasised the importance of the continuous at-sea deterrent, stating: “A key point for all of us in this House, our nation and our alliances is that it is a continuous at-sea deterrent, and I reassure everyone that we maintain that.”
He described the deterrent as having underpinned peace and security for decades and said it has been sustained under successive governments. Lord Bruce of Bennachie later questioned how many submarines are operational at any one time, citing periods when boats have been unavailable due to maintenance, and raised concerns about the ability to sustain the programme while delivering future commitments such as AUKUS.
Lord Coaker declined to give figures on operational availability, saying: “I will not go into the number of submarines that are operational for obvious reasons.” However, he referred to the Royal Navy’s submarine recovery plan, which aims to improve docking and maintenance capacity in order to increase availability. He said those measures are intended to ensure the fleet can meet current requirements while supporting future submarine programmes.
How many are working? What a going no where nothing new story, its like the Navy confirming it has two Carriers, this is just another nothing story by the MOD about nothing new.
How many currently at sea? 2.
They are all working.
Really ?
😅
It’s not a MOD story though, it’s a UKDJ one. A question was asked in the House of Lords and an answer was given. The UKDJ then thought it sufficiently interesting enough to put up an article about it. Why get annoyed at that?
“Two additional Astute-class submarines are currently under construction”
That’ll be a surprise to the crew who dived HMS Agamemnon last October. I’ll bet they didn’t realize we did basin dives while the ship was still under construction. I do hope the scaffolding didn’t get in the way. Come to think of it, it’s a commissioned ship too. The King turned up and everything.
Maybe they meant Ten ? 😁
This is Fantastic news, to think we have 9 Cutting edge World class, State of the art Submarines all ready at the push of a button (NOOO not that button 😱) ready to “Unleash Hell” on any aggresso, makes one feel safe at night.
I’m guessing It’s two then ? r
Hopefully we can get the Astute maintenance program on a more even keel and the last two boats into service. We are suppose to be deploying an Astute permanently to Australia in a few years which should be very doable from a fleet of 7.
You would think an “Even Keel” would be a given really.
