Project history

For the 1912 Programme three near-repeats of the Chatham class were approved. The only alterations were to add a second 152mm on the forecastle, side by side to improve ahead fire, and additional flare of the forecastle to reduce spray. Also they received new 45cal 152mm guns. Like the Chatham class they proved highly successful in service and they were retained in the post-war Navy.

Adelaide was the oldest cruiser (considering from the moment of the design approval and laid down date) of British Empire served in the Second World War. She was built in Australia for its Navy under the design of cruiser Birmingham from 1910 and become obsolete in days of the First World War, because of last circumstance completion was conducted very slowly.
