This operational success at a critical moment proved in many ways to be the pinnacle of the RCN during the Cold War. The following year, Prime Minister Lester Pearson’s Liberals came to power with a commitment to reorganize national defence. In 1964, integration of the navy with the air force and army did away with the separate service staffs, and unification in 1968 saw the controversial transition of the RCN into a subordinate Maritime Command, causing a number of admirals to resign in protest. At the same time, a slashing of the defence budget made it no longer affordable to maintain a naval aviation branch, and the carrier Bonaventure was scrapped in 1970.

A decade earlier in 1960, on its golden anniversary, the RCN had boasted a fleet of some 50 warships (the carrier, 14 St. Laurent-class destroyer-escorts with another 6 under construction, 23 converted wartime destroyers and frigates, and 10 minesweepers) crewed by 21,500 sailors. By 1970, other than the ageing St. Laurent-class vessels, the navy had only an operational support ship and three Oberon-class training submarines acquired in the mid-1960s, plus the expectation of four new gas-turbine-powered, helicopter-carrying destroyers (the Iroquois class) and two more operational support ships (the Protecteur class) for fewer than 10,000 sailors. By the mid-1970s, Maritime Command had reorganized into the semblance of a naval staff. With these reduced forces constituting the fleet that would serve out the last two decades of the Cold War, it was to oversee a navy that actively exercised with its alliance partners but as an increasingly marginal element, even within its anti-submarine specialty.

New Ships, New Wars

The fall of the Berlin Wall in 1989 coincided with the long-deferred fleet renewal that included 12 Halifax-class frigates in various stages of building, a major mid-life upgrade for the four Iroquois-class destroyers, and 12 maritime coastal-defence vessels planned to revive a mine-clearing capability for the naval reserve. However, the cancellation of a program for 10–12 nuclear-powered submarines signalled the probability of yet another period of retrenchment.

In a completely unexpected course of events, Iraq invaded Kuwait in August 1990, and Canada found itself, yet again, at war and with a navy well placed to respond. The navy’s operational focus shifted from North Atlantic open-ocean anti-submarine warfare to maritime security operations in the hot, humid, and confined waters of southwest Asia, where it maintained a presence for the ensuing quarter century.

The two years following the terror attacks of September 11, 2001, witnessed a particularly active pace of operations—greater than that of the Korean War—in which 17 Canadian warships (every major vessel except two in long refit) served off southwest Asia. A succession of Canadian commodores also held the prestigious command of the coalition fleet in the Arabian Sea in support of international forces in Afghanistan.

Other globe-girdling operations included deployments to East Timor, a circumnavigation of the continent of Africa, seemingly annual forays to various points in the Caribbean, and a deployment to the south Atlantic for an RCMP drug bust off Angola. Closer to home, the navy has been at the forefront of the annual Armed Forces operations in the Arctic.

21st-Century Shipbuilding

Now into its second century, the RCN finds itself embarking upon another postwar period of fleet renewal in uncertain budgetary times. The government of Prime Minister Stephen Harper announced in September 2014 that the Iroquois- and Protecteur-class warships would end service in 2015. Two new support ships are expected to be ready by 2020, but the first of 12–15 replacement warships probably won’t be before 2025, and then at the modest national shipbuilding procurement strategy rate of one every two years. A flotilla of five or six Arctic offshore patrol vessels should also be ready by 2020.

With the four problem-plagued Victoria-class submarines acquired from Britain in the early 2000s finally achieving full operational capability and the 12 Halifax-class frigates coming out of a major mid-life modernization program, the core of the navy’s fighting forces well into the 21st century will be formed.
