Warship Weeks were British National savings campaigns during the Second World War, with the adoption of a Royal Navy warship by a civil community. A level of savings would be set to raise enough money to provide the cost of building a particular naval ship. The aim was for cities to raise enough to adopt battleships and aircraft carriers, while towns and villages would focus on cruisers and destroyers. Smaller towns and villages would be set a lower figure. Once the target money was saved for the ship, the community would adopt the ship and its crew.
