LARGS, SCOTLAND - FEBRUARY 27:  In this handout image provided by MoD Crown Copyright, HMS Vengeance departs for Devonport prior to re-fit on Ferbruary 27, 2012 off the coast of Largs, Scotland. The UK Ministry of Defence has awarded UK's leading naval support business Babcock, on March 25, 2012, with a contract to commence the planning phase for the ?350 million GBP refit of Trident ballistic missile submarine HMS Vengeance, which will be undertaken at their Devonport Royal Dockyard. The project to upgrade and refuel the nuclear submarine will safeguard 2,000 UK jobs and will take around three and a half years. River Tamar shipping was suspended when the the 150m-long, 15,900-tonne submarine HMS Vengeance travelled to the Devonport Dockyard ahead of the scheduled refit on March 2, 2012, arriving amid concerns without a signed contract for the refit.  HMS Vengeance will be the last of four Vanguard class submarines to undergo a Lond Overhaul Period and Refuel LOP(R) at Davernport that will commence once HMS Vigilant leaves Devonport on completion of her LOP(R) in 2012.

Questions raised over effectiveness of Trident nuclear deterrent system

Washington CNN  — 

A missile test involving Britain’s Trident nuclear deterrent system ended in failure off the coast of Florida last year, a US defense official with direct knowledge of the incident told CNN on Monday.

The official told CNN that the incident, which happened last June in an the area off the Florida coast used by the US and the UK for missile tests, did not in involve a nuclear warhead.

Britain’s Sunday Times newspaper reported that the missile veered towards the US coast, but the US official told CNN that this trajectory was part of an automatic self-destruct sequence. The official said the missile diverted into the ocean – an automatic procedure when missile electronics detect an anomaly.

A month after the test, the UK parliament approved the renewal of Trident at a cost of £40 billion. Unaware of the failure, members of the House of Commons voted by 472 votes to 117 in favor of renewal.

A Trident missile is launched by the US navy during a test in 1989.

On Sunday, British Prime Minister Theresa May was asked four times during an interview with the BBC’s Andrew Marr Show whether she knew of the missile failure before the vote. May refused to answer.

Government challenged on CNN report

Forced to make a statement on the controversy in the House of Commons on Monday, British Defense Secretary Michael Fallon said he had “absolute confidence” in Trident but refused to give “operational details” about the test.

CNN published this story just as Fallon spoke, and Mary Creagh, of the opposition Labour Party demanded to know why he would not give any further details.

Citing CNN’s story she said: “The Secretary of State has advised us not to believe everything we read in the Sunday newspapers, but should we believe the [US] official who, while we’ve been sitting here debating, has confirmed to CNN that the missile did auto-self-destruct off the coast of Florida? And if that is the case, why is the British parliament and the British public the last people to know?”

Fallon once again declined to give “operational details”.

Another Labour lawmaker, Chris Byrant, said the reporting by CNN and the Sunday Times demonstrated the need for a full investigation.

“We deplore the leakage of any information about the nuclear deterrent but it is not for me to comment on what may or may not be said by the United States administration,” Fallon replied. “This is our submarine, our deterrent, and it is our responsibility to apply to it the very highest security classification.”

May under fire

The UK government’s refusal to discuss the missile failure has prompted criticism from opponents of the UK’s nuclear deterrent.

Scotland’s First Minister Nicola Sturgeon tweeted: “This is a hugely serious issue. There should be full disclosure of what happened, who knew what/when, and why House of Commons wasn’t told.”

Earlier on Monday, a spokeswoman for May said she was briefed on the Trident test when she came into office.

The Prime Minister and the Defense Secretary are routinely informed about tests and their outcome, May’s spokeswoman told reporters.

“These are known as a ‘demonstration and shakedown’ test. This test was in June (2016) under the last prime minister (David Cameron). On taking office the current Prime Minister (Theresa May) was briefed on a range of nuclear issues, including this. This test saw the submarine and crew successfully tested and certified.”
