Trident Nuclear Programme

Lord West of Spithead Excerpts

Monday 7th December 2020 Lords Chamber

Asked by

[Lord West of Spithead]

To ask Her Majesty’s Government whether a new United Kingdom warhead is required to extend the Trident nuclear programme to 2049; and if so, by when it will be required.

[The Minister of State, Ministry of Defence (Baroness Goldie) (Con) [V]]

My Lords, in order to ensure that the Government maintain an effective deterrent throughout the commission of the Dreadnought class submarines and into the future, the Secretary of State for Defence formally announced to Parliament on 25 February 2020 that the UK will replace its nuclear warhead. The replacement warhead programme will be delivered to a schedule that ensures that our deterrence posture under Operation Relentless endures uninterrupted. I am withholding specific information about the in-service date to safeguard national security.

[Lord West of Spithead (Lab)]

I thank the Minister for her Answer. I am delighted that we are pressing ahead with this. It is a part of our armoury that is used every single day in deterring, so I am pleased about it. However, I have great concerns about AWE. Repeated ministerial deferrals post 2010 have resulted in decay of nuclear expertise and cost escalation within AWE, as has been noted by the NAO. Could the Minister confirm, after the failures of the MENSA, Hydrus and Pegasus projects to deliver on time and within budget, and the scathing assessment by the NAO earlier this year, that AWE as currently structured is able to deliver such a complex programme on time and at cost?
