This is another book in this series, each concerning itself with one particular type or class of ship. This one is about British Anti-/Aircraft Cruisers and includes ships specifically built for this mission or converted to it. As usual for this series, it is not so much a history of the ships, although brief accounts of their careers are included, as it is a description of the various specific modifications made to them that made them anti-aircraft ships. Included are the “C” class cruisers that were converted for this work, merchant vessels that were requisitioned and converted and the more-or-less purpose build Dido Class ships.
