I want to know the answer to the following question:
What aircraft carrier received maintenance at Devonport Dockyard?
All the background I'm provided with is that "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.". Is that enough to answer the question?
