Mr Philip Hammond: To date, the Ministry of Defence (MOD) has spent £17.033 million on long lead items for the successor submarines. This spend is associated with the development of the Pressurised Water Reactor 3 plant to be used in the submarines.
The MOD has not spent any money on long lead items for nuclear weapons. The Strategic Defence and Security Review determined that a replacement warhead would not be required until the 2030s. Therefore the decision to refurbish or replace the existing warhead will not be required until the next Parliament.
