The United Kingdom’s future nuclear deterrent: 2012 update to Parliament

This report explains the progress the MOD has made on this programme.

This was published under the 2010 to 2015 Conservative and Liberal Democrat coalition government



On 18 May 2011, the Ministry of Defence (MOD) announced that the first milestone (known as Initial Gate) for the successor deterrent submarine programme had been passed and that a five year long, £3 billion assessment phase had been approved. The main purpose of the assessment phase is to refine the design of the successor submarine prior to the main investment decision (known as Main Gate), which will be taken in 2016.

This is the first of a series of annual reports that will explain the progress the MOD has made on this programme and set out what is expected to be achieved over the coming year.
