asked the First Lord of the Admiralty if the date for the coming naval mobilisation and review by His Majesty at Spithead is definitely fixed for 18th July; what is the number and description of each class of vessel which will be assembled there for review; if any provision is contemplated whereby Members of both Houses of Parliament can be present at this review as in former years; if he will place in the Tea Room a chart showing the position of the ships; if he will state if the regulations which yachts, passenger vessels, and other merchant ships will have to obey during the review have yet been issued; and, if not, how soon they will be available?
Information about the UK’s continuous at sea deterrent (CASD) and the Successor programme to replace the Royal Navy’s Trident missile Vanguard Class Submarines.
The protection and defence of the UK is a primary responsibility of the government. The government is committed to maintaining the UK’s national nuclear deterrent based on a ballistic missile submarine for as long as the global security situation makes that necessary.
The continuous at sea deterrent (CASD) has provided the United Kingdom’s ultimate security insurance policy every day for the last 46 years.
Since 1992 the 4 boats of the Vanguard Class have maintained CASD, ensuring at all times 1 submarine was deployed. As the Vanguard submarines progress to the end of their lifespan, the UK is looking at the next generation of submarines to carry forward the vital role. This is called the Successor submarine programme.
