British Prime Minister Theresa May has been put under pressure to answer questions over whether she deliberately withheld knowledge of a malfunction of a Trident missile fired from HMS Vengeance weeks before she lobbied Parliament for the nuclear deterrent to be renewed. The accusation was made by The Sunday Times newspaper claiming a “naval source” broke the story of the malfunction to them.
In June 2016, the Vanguard-class SSBN HMS Vengeance test fired an unarmed Trident II D5 nuclear missile as part of an operation which is designed to certify the submarine and its crew for conducting nuclear deterrence patrols with live nuclear weapons. In the wake of the The Sunday Times claims the MoD issued a statement saying;
Vengeance and her crew were successfully tested and certified, allowing Vengeance to return into service. We have absolute confidence in our independent nuclear deterrent.
The newspaper claims that the missile, which was intended to be fired 5,600 miles to a target area off the west coast of Africa, malfunctioned and instead veered towards the US. Interviewed by Andrew Marr on the BBC, the Prime Minister rebuffed four questions regarding the claim which has left her exposed to criticism from the leaders of two of the major British political parties – Nicola Sturgeon of the Scottish National Party and Jeremy Corbyn of the Labour Party – both of whom have routinely voiced their opposition to maintaining the British nuclear deterrent.
Both the MoD and Downing Street have issued statements denying the newspaper’s claims regarding a malfunction but there are still calls for an investigation.
On July 18th 2016, a month after the test took place, Parliament voted 472-117 to renew the nuclear deterrent based around the Trident II D5 Submarine Launched Ballistic Missile (SLBM) carried by the new Dreadnought-class SSBNs. The first Dreadnought-class is expected to enter service in 2028 and the cost of the entire project is expected to be around £40bn.
