Plymouth has been left out of a government plan that will see £500 million go to one of Devonport's rival dockyards - Faslane on the Clyde.
Alongside Portsmouth and Devonport, Faslane is one of three major naval hubs, and is the home of Britain’s Trident nuclear deterrent.
The money will go towards a 10-year infrastructure project which is expected to begin in 2017. The plans include building sea walls and jetties, and will create thousands of jobs.
Two submarines from Devonport will also be moved up to Faslane in 2020.
