Deferred nuclear investment and the defence budget

If Britain's major defence-spending increase is delayed until 2034, what happens to submarine timelines?

The nuclear and submarine programmes are already receiving funding, although concentrating deferred work into a few years places heavy pressure on the budget.

Nuclear submarines are identified as an area receiving funding within the Defence Investment Plan. The comparison describes France as spreading nuclear expenditure consistently over twenty years and Britain as trying to economize for sixteen before paying heavily over the final four. The figures quoted are roughly 297.7 billion pounds of defence expenditure over four years, including more than sixty billion for nuclear work. The twelve F-35As' nuclear role is also said to move part of their procurement into the nuclear funding category. That accounting change links the next aircraft purchase to both air and nuclear budgets.
