HMS Campania was an escort aircraft carrier of the Royal Navy that saw service during the Second World War. After the war, the ship was used as a floating exhibition hall for the 1951 Festival of Britain and as the command ship for the 1952 Operation Hurricane, the test of the prototype British atomic bomb. She was built at Harland & Wolff shipyards in Belfast, Northern Ireland. When construction started in 1941 she was intended as a refrigerated cargo ship for transporting lamb and mutton from New Zealand, but was requisitioned by the British Government during construction and completed and launched as an escort carrier, entering service in early 1944. The ship was of a similar, but not identical design to the other ships of the Nairana class. (Wikipedia)
