In a statement, AWE said “The UK Defence Spending Review, announced by the Prime Minister, outlines significant investment in nuclear security, including the modernisation of infrastructure at AWE.
“AWE’s nuclear warhead programme features some of the most advanced and sensitive science, engineering and manufacturing facilities in the UK.”
The Prime Minister said the world had changed and there was greater instability and the UK needed to respond to those threats.
He added: “We have seen what’s happened in Ukraine… Russia has shown in recent weeks it is not serious about peace and we have to be ready.”
