The complexity and uniqueness of a nuclear submarine require special skills, facilities, and oversight not supported by other shipbuilding programmes. In fact, a single shipyard, Barrow-in-Furness, designs and builds the United Kingdom's nuclear submarines, and many of the vendors that support submarine construction are sole-source providers. With such specialisation, in addition to a limited design and production demand, there is concern about whether the submarine industrial base can maintain its viability into the future. This report seeks to determine what actions should be taken to maintain nuclear submarine design capabilities and how nuclear submarine production should be scheduled for efficient use of the industrial base. Based on their findings, the authors recommend that the Ministry of Defence determine the scheduling of construction for future submarine contracts as soon as possible; plan to retain a design core of designers, engineers, and draughtsmen during periods of reduced demand; and take steps towards collaboration with other countries.

Cost increases in maintaining regulating licenses at BAE Systems' Barrow-in-Furness shipyard and Devonport Management Limited's (DML's) facility have led the UK Ministry of Defence to consider the possibility of consolidating its nuclear fuel-handling capabilities at DML. This report assesses where the United Kingdom's nuclear fuelling of submarines should occur to best minimise cost and schedule risks, particularly regarding the Astute submarine programme, which is already under way.

For the first time since the design of the first nuclear submarine, the U.S. Navy has no nuclear submarine design program under way, which raises the possibility that design capability could be lost. Such a loss could result in higher costs and delays when the next submarine design is undertaken, as well as risks to system performance and safety. The authors estimate and compare the costs and delays of letting design capability erode vs. those of alternative means of managing the workload and workforce over the gap in design demand and beyond. The authors recommend that the Navy consider stret.
