HMS Campania (D48)

HMS "Campania", pennant number D48, was an escort aircraft carrier of the Royal Navy that saw service during World War II. 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 over 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 ships of the "Nairana"-class.

World War II

"Campania" operated escorting convoys and doing anti-submarine work in the Atlantic and Arctic theatres. In December 1944 her Swordfish aircraft sank the German submarine U-365 while the "Campania" was escorting the Arctic convoy Convoy RA-62.

The ship survived the war, and unlike other Royal Navy escort carriers was not immediately scrapped or sold. She was briefly used as an aircraft-transport before being decommissioned and placed in reserve in December 1945.

Festival of Britain

In 1951 she was the Festival of Britain's exhibition ship, touring the country's ports with a civilian crew as the "Festival Ship Campania" to supplement the main exhibition in London and two thousand local events.

The Festival Office's resident designer, John Holland, considered that the vessel would "not convert easily into a showboat", but with the massive demand for shipping to help rebuild Europe after the war, he and his colleagues felt lucky to have any ship at all.

Repainted white, the ship was decorated with skeleton masts and bunting. Officially named the Sea Travelling Exhibition, the exhibits were intended to reflect the main London Exhibition. Like the Festival's Land Travelling Exhibition, they were divided into three sections, the "Land of Britain", "Discovery" and "The People at Home". Between 4 May 1951 and 6 October, the ship visited Southampton, Dundee, Newcastle, Hull, Plymouth, Bristol, Cardiff, Belfast, Birkenhead and Glasgow, staying at each port for 10-14 days.

Operation Hurricane

With the festival over, the ship was refitted in Birkenhead for a very different role, as the command ship for Operation Hurricane, the test of the first British atomic bomb on the Monte Bello Islands off western Australia. The refit saw the exhibition replaced by workshops, laboratories, offices and cabins, plus a desalination plant since the Monte Bello Islands did not have any indigenous fresh water source to supply the 1500 personnel who would take part in the test.

Four other ships were directly involved in the test, the landing ships HMS "Narvik", HMS "Zeebrugge", HMS "Tracker" and a frigate, HMS "Plym". "Tracker" was designated as the Health Ship and extensively equipped with decontamination facilities, whilst the weapon was to be detonated aboard "Plym". The flotilla was under the overall command of Rear Admiral Arthur David Torlesse.

Heavily laden with crated equipment and deck cargo, including three Dragnonfly helicopters and two Sea Otter aircraft and deck cargo, the ship departed from Portsmouth for the islands on 2 June 1952. Eighty-five scientists were also onboard as passengers, around half directly involved in British nuclear programme and the remainder from other parts of the British civil service.

The vessel arrived at the Monte Bello Islands on 8 August after calling into Gibraltar, Cape Town, Mauritius and Fremantle and the next two months were spent preparing for the test, which took place on 3 October. "Campania" was not found to be particularly suitable as the main base for the test, partly because it was hot and cramped, and partly because there were insufficient boats for ferrying them between the ship and the shore and the eight pinnaces intended to perform about a third of the work could not moor close to the ship at night because the water was too choppy. Most of the scientists and engineers soon moved to tented accommodation ashore.

The ship was decommissioned for the final time in December 1952 following her return to the United Kingdom, and sold and scrapped in Blyth in 1955.
