Ships of Commonwealth

The "Commonwealth of Nations" was born in the early 20th century during the waning years of the British Empire. Officially formed in December 1931 via the Statute of Westminster, the original seven member states were the United Kingdom, Australia, Canada, New Zealand, South Africa, Ireland, and Newfoundland. Today, it is made up of 52 sovereign states that span the globe, and currently includes nations that had no previous political or economic ties to the United Kingdom or the British Empire.

Several of the various nation-states that comprise the Commonwealth deploy their own military forces. Collectively, they are represented in World of Warships under a single flag, but each navy has its own history and traditions.

Established following the introduction of the Naval Service Bill by then Prime Minister Sir Wilfrid Laurier, the Naval Service of Canada (NSC) was intended as a distinct naval force for the Dominion, that, should the need arise, could be placed under British control. The bill received royal assent on 4 May 1910. Initially equipped with two former Royal Navy vessels, HMCS Niobe and HMCS Rainbow, King George V granted permission for the service to be known as the Royal Canadian Navy on 29 August 1911.

During the first years of the First World War, the RCN's six-vessel naval force patrolled both the North American west and east coasts to deter the German naval threat, with a seventh ship, HMCS Shearwater joining the force in 1915. Just before the end of the war in 1918, the Royal Canadian Naval Air Service was established with the purpose of carrying out anti-submarine operations; however, it was disbanded after the armistice of 11 November.

After the war, the Royal Canadian Navy took over certain responsibilities of the Department of Transport's Marine Service, and slowly started to build its fleet, with the first warships specifically designed for the RCN being commissioned in 1932. At the outbreak of the Second World War, the Navy had 11 combat vessels, 145 officers and 1,674 men. During the Second World War, the Royal Canadian Navy expanded significantly, ultimately gaining responsibility for the entire Northwest Atlantic theatre of war. By the end of the war, the RCN had become the fifth-largest navy in the world after the United States Navy, the Royal Navy, the Imperial Japanese Navy, and the Soviet Navy, with over 900 vessels and 375 combat ships. During the Battle of the Atlantic, the RCN sank 31 U-boats and sank or captured 42 enemy surface vessels, while successfully completing 25,343 merchant crossings. The Navy lost 24 ships and 1,797 sailors in the war.

In 1940–41, the Royal Canadian Navy Reserves scheme for training yacht club members developed the first central registry system.

From 1950 to 1955, during the Korean War, Canadian destroyers maintained a presence off the Korean peninsula, engaging in shore bombardments and maritime interdiction. During the Cold War, the Navy developed an anti-submarine capability to counter the growing Soviet naval threat. In the 1960s, the Royal Canadian Navy retired most of its Second World War vessels, and further developed its anti-submarine warfare capabilities by acquiring the Sikorsky CH-124 Sea King, and successfully pioneered the use of large maritime helicopters on small surface vessels. At that time, Canada was also operating an aircraft carrier, HMCS Bonaventure, flying the McDonnell F2H Banshee fighter jet until 1962, as well as various other anti-submarine aircraft.

HMAS Perth, Tier VI cruiser

With the vast majority of its population spread along the long coastlines of the country, Australia relied upon detached units from the Royal Navy to provide naval defense for over a hundred years. This remained the status quo until 1909, when talks began of a dedicated naval unit to be deployed to Australian waters. It was decided between the British Admiralty and the Australian Government that Australia would purchase a "fleet unit" consisting of six destroyers, three cruisers, three submarines, various auxiliaries, and a battlecruiser. The first two ships, HMAS Yarra and HMAS Parramatta, reached Australian waters in November 1910, and on 10 July 1911 King George V granted the title of Royal Australian Navy to the Commonwealth Naval Forces. By 1913, the completed Australian fleet — led by battlecruiser HMAS Australia — entered Sydney Harbour for the first time.

The RAN served on the frontlines of World War I, supporting Australian landings in the invasion of the German New Guinea colonies and attacking the Ottoman Navy in the Sea of Marmora during the Gallipoli campaign. HMAS Sydney faced off alone against SMS Emden in the middle of the Indian Ocean and won — earning the RAN's first victory at sea — while HMAS Australia was later involved in the Battle of Jutland. After the war, the RAN like many other navies was forced to make changes as a result of the Washington Naval Treaty of 1922, losing their only battlecruiser, but gaining several pre-war submarines and destroyers.

During the inter-war period, older ships were sold for scrap while newer heavy cruisers, light cruisers, submarines, destroyers, and a seaplane carrier found their way into RAN service. Hampered by the inter-war disarmament policies due to shifting economic and political situations, the RAN rose once again to fight in World War II. Throughout 1940, the RAN distinguished itself in the Mediterranean with the famous destroyers of the "Scrap Iron Flotilla". RAN units returned to defend the Australian homeland when war broke out in the Pacific and enemy ships prowled Australian waters, fighting against the encroaching Empire of Japan as close to home as the Coral Sea.

Since the end of the Second World War, the Royal Australian Navy has served in operations from the Korean Theatre to East Timor, focusing on protecting Australia’s interests in the southwestern Pacific region and peacekeeping around the globe with a 50-strong fleet of modern destroyers, frigates, submarines, and auxiliaries.
