By what year was the greater part of the army presence in Plymouth gone?
Post-war, Devonport Dockyard was kept busy refitting aircraft carriers such as the Ark Royal and, later, nuclear submarines while new light industrial factories were constructed in the newly zoned industrial sector attracting rapid growth of the urban population. The army had substantially left the city by 1971, with barracks pulled down in the 1960s, however the city remains home to the 42 Commando of the Royal Marines.
