Royal Canadian Navy
The Royal Canadian Navy is the naval force of Canada. The navy is one of three environmental commands within the Canadian Armed Forces. As of February 2024, the RCN operates 12 s, 4 s, 4 s, 5 s, 8 s, and several auxiliary vessels. Officially, the RCN consisted of 7,700 Regular Force and 4,100 Primary Reserve sailors, supported by 3,800 civilians.
Founded in 1910 as the Naval Service of Canada and given royal sanction on 29 August 1911, the RCN was amalgamated with the Royal Canadian Air Force and the Canadian Army to form the unified Canadian Armed Forces in 1968, after which it was known as Maritime Command until 2011.
In 2011, its historical title of "Royal Canadian Navy" was restored. The RCN has served in the First and Second World Wars, the Korean War, the Persian Gulf War, Afghanistan, and numerous United Nations peacekeeping missions and NATO operations.
History
1910–1968
Established following the introduction of the Naval Service Act by Prime Minister Sir Wilfrid Laurier, the Naval Service of Canada was intended as a distinct naval force for Canada that could, should the need arise, 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 RCN 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 RCN expanded significantly, ultimately gaining responsibility for the entire Northwest Atlantic theatre of war. During the Battle of the Atlantic, the RCN sank 31 U-boats and sank or captured 42 enemy surface vessels, while completing 25,343 merchant crossings. The navy suffered the loss of 33 ships and 1,797 sailors. To gain experience with the operation of aircraft carriers, RCN personnel crewed two Royal Navy escort carriers from 1944 to 1946:, and.
Starting in May 1944, when Canada began drafting plans to assume a larger role in the Pacific Theatre after achieving victory in Europe, the Canadian government recognized that the RCN would require much larger vessels. Canadian naval staff advocated for HMS Nabob and HMS Puncher to be given back to the Royal Navy in exchange for two light fleet carriers. The Canadian government agreed to acquire two carriers on loan from the Royal Navy, with an option to purchase them, but they were not ready before the war ended. Postwar budget cuts meant that Canada could only afford to operate one aircraft carrier, instead of two as originally planned. The RCN operated from 1946 to 1948, before exchanging it with the Royal Navy for the slightly larger.
From 1950 to 1955, during and after the Korean War, Canadian destroyers maintained a presence off of 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 November 1956, HMCS Magnificent was chosen to transport men and supplies to Egypt as part of Canada's response to the Suez Crisis. In preparation for use as a transport, the ship's weapons were stripped, and her complement was reduced to 600 personnel. The initial plan was to embark the Queen's Own Rifles of Canada, but that order was rescinded in December. Magnificent waited in Halifax until the end of the month, then sailed for Egypt carrying 406 Canadian troops and their vehicles, four Royal Canadian Air Force de Havilland Canada DHC-3 Otters, and a single H04S helicopter. She returned to Canada in March 1957. Later in 1957, the RCN paid off HMCS Magnificent and commissioned, which was better suited for jet aircraft. She flew the McDonnell F2H Banshee fighter jet until 1962, as well as various other anti-submarine aircraft until her decommissioning. In the 1960s, the RCN 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.
1968–present
From 1964 through 1968, under Prime Minister Lester B. Pearson, the RCN, Royal Canadian Air Force and Canadian Army were amalgamated to form the Canadian Armed Forces. This process was overseen by then–defence minister Paul Hellyer. The controversial merger resulted in the abolition of the RCN as a separate legal entity. All personnel, ships, and aircraft became part of Maritime Command, an element of the Canadian Armed Forces. The traditional naval uniform was eliminated and all naval personnel were required to wear the new Canadian Armed Forces rifle green uniform, adopted also by former Royal Canadian Air Force and Canadian Army personnel. Ship-borne aircraft continued to be under the command of MARCOM, while shore-based patrol aircraft of the former Royal Canadian Air Force were transferred to MARCOM. In 1975 Air Command was formed and all maritime aircraft were transferred to Air Command's Maritime Air Group. The unification of the Canadian Forces in 1968 was the first time that a nation with a modern military combined its formerly separate naval, land and air elements into a single service.File:HMCS ATHABASKAN F-282, Halifax NS, August 1990..jpg|thumb|left| departing Halifax for the Persian Gulf as part of the Coalition forces. Canada deployed three ships in support of Operation Desert Shield, and later Operation Desert Storm
HMCS Bonaventure was sold off in 1970, shortly after completing a 16-month, $11 million mid-life refit. The 1970s saw the addition of four s, which were later updated to air defence destroyers, and in the late 1980s and 1990s the construction of twelve s and the purchase of the s. In 1990, Canada deployed three warships to support Operation Friction. Later in the decade, ships were deployed to patrol the Adriatic Sea during the Yugoslav Wars and the Kosovo War. More recently, Maritime Command provided vessels to serve as a part of Operation Apollo and to combat piracy off the coast of Somalia.
Following the Official Languages Act enshrinement in 1969, MARCOM instituted the French Language Unit, which constituted a francophone unit with the navy. The first was. In the 1980s and 1990s, women were also accepted into the fleet, with the submarine service the last to allow them, beginning in 2001.
Some of the changes that had taken place during the unification of the forces began to be undone. In 1985, MARCOM received new black uniforms, differentiating them from the land-based forces. By 1990, the three senior naval officers of MARCOM had recreated the Naval Board. On 16 August 2011, the government restored the historic names of the Canadian Forces' three environmental commands: Maritime Command became the "Royal Canadian Navy", Air Command the "Royal Canadian Air Force," and Land Force Command the "Canadian Army."
As of August 2015, with the loss of area air defence and resupply capabilities, the RCN was then classified as a Rank 5 navy on the Todd-Lindberg navy classification system of naval strength, dropping from Rank 3 in 2005. Vice-Admiral Angus Topshee, the commander of the RCN, indicated in 2023, the "effective strength" of the regular force was considerably lower with numerous naval trades having shortages in trained strength of more than 20 percent. In late 2025, Vice-Admiral Topshee stated that the Navy's personnel problem had not been solved and remained dire, while the Auditor General of Canada reported deeper systemic problems with Canadian military recruitment.
In December 2025, Iran designated the Royal Canadian Navy as a “terrorist organization”. Iran's foreign ministry stated the decision was made “within the framework of reciprocity”, after the Government of Canada listed the Islamic Revolutionary Guard Corps as a terrorist entity in 2024.
Structure
The RCN is headquartered at National Defence Headquarters in Ottawa, Ontario. Since 1968, the RCN has been an environmental command of the Canadian Armed Forces and since 2012 it has been charged with maintaining and generating forces for the Canadian Joint Operations Command.Naval Staff Headquarters
The RCN is directed through Naval Staff HQ by the Commander of the RCN, as the Chief of Naval Staff, whose mission is to lead the strategic development and generation of combat capable multi-purpose maritime forces and to provide advice in support of maritime operations.Maritime Forces Atlantic
The RCN's Atlantic Fleet, known as Canadian Fleet Atlantic is co-located with Maritime Forces Atlantic, with headquarters at CFB Halifax in Halifax, Nova Scotia. It is supported by CFS St. John's in Newfoundland. Attached to MARLANT and CFB Halifax is the Royal Canadian Air Force's 12 Wing Shearwater, based at Shearwater Heliport, which provides shipborne air support for the Atlantic Fleet. The RCAF's 14 Wing Greenwood provides fixed-wing air support for MARLANT through 404 Maritime Patrol and Training Squadron and 405 Maritime Patrol Squadron. Other Atlantic Fleet facilities are CFAD Bedford, an ammunition depot, and two radio stations, Naval Radio Section Newport Corner and NRS Mill Cove.The Atlantic Fleet, with 18 warships and a number of auxiliary vessels, is responsible for Canada's exclusive economic zone on the East Coast, as well as Canada's area of responsibility in the Atlantic Ocean and the eastern Arctic Ocean.
