The British assembled a small fleet for Operation Hurricane that included the escort carrier , which served as the flagship, and the LSTs "Narvik", "Zeebrugge" and "Tracker", under the command of Rear Admiral A. D. Torlesse. Leonard Tyte from the AERE was appointed the technical director. "Campania" had five aircraft embarked, three Westland WS-51 Dragonfly helicopters and two Supermarine Sea Otter amphibians. Between them, the LSTs carried five LCMs and twelve LCAs. The bomb, less its radioactive components, was assembled at Foulness, and then taken to the River-class frigate on 5 June 1952 for transport to Australia. It took "Campania" and "Plym" eight weeks to make the voyage, as they sailed around the Cape of Good Hope instead of traversing the Suez Canal, because there was unrest in Egypt at the time.
