Alex visited BAE Systems in Barrow-in-Furness to cut steel on Warspite, the third of four new submarines that will carry our country’s continuous-at-sea nuclear deterrent.
Advanced nuclear submarines enable the UK to maintain a safe and credible capability to deter any adversary, and provide security to our allies.
Alex said:
"Our nuclear deterrent protects every UK citizen from the most extreme threats, every minute of every day, and progress on the Dreadnought Class is crucial to maintaining our national security.
"This milestone is a significant step forward in the Dreadnought programme, supporting thousands of jobs and apprenticeships across the country, and protecting the UK and our allies for decades to come."
