Steve Timms, Managing Director of BAE Systems’ Submarines business, said: "Today’s milestone is a really significant moment for the thousands of employees here at BAE Systems and across the submarines enterprise who are working together to deliver the Dreadnought Class. “We are immensely proud of the role we play in delivering this truly national endeavour for the Royal Navy and our contribution to protecting national security.†Attending the ceremony, Defence Procurement Minister Alex Chalk KC, 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.†|

| HMS Stratagem sailed from Trincomalee on 10th November 1944 with orders to patrol in the vicinity of Malacca where it was believed the Japanese were loading ships with bauxite ore. On the afternoon of the 18th Stratagem attacked and sank the tanker Nichinan Maru. On 22nd November a Japanese aircraft spotted the submarine and directed a destroyer to where it had dived. Just after midday the destroyer attacked, the first depth charge causing the submarine's bow to strike the bottom. The submarine was plunged into darkness and the forward part began to flood. Attempts to shut the watertight door to the forward compartment failed and the crew were forced to make their escape. Ten crew managed to escape, of which eight were taken Prisoner of War. Only three of these (who were taken to Japan) survived captivity. The other five were executed in Singapore by the Japanese. | |
