The risk of concentrating British warship construction

What are the risks of concentrating Royal Navy shipbuilding in Scotland?

Past fleet contraction hollowed out English and Welsh capacity, so future expansion would be more resilient if work and investment were spread across more yards.

During the Royal Navy's contraction, most English yards and all Welsh capacity disappeared while Scottish yards retained much of the available work. This left Britain with a narrow industrial base as the fleet began seeking renewed investment. Surviving yards such as Cammell Laird and Appledore could support a broader programme. Concentrating every new warship in a single region would create further risk. Shipyard geography affects strategic resilience as well as politics and employment.
