The decade from 1945 to 1955 was a period of rapid
technical and structural change described by Norman
Friedman as the “postwar naval revolution.” This marked
the shift away from escort strategies to concepts such as
attack-at-source, ocean barrier, and the reliance on undersea
sound surveillance systems. The fast modern forces required
for these various missions rendered many fleets built during
the Second World War obsolete or at best in need of extensive
modernization. The RCN attempted to parallel the changes
in British and American fleet structures and roles that
combined constitute Friedman’s naval revolution; it did so,
however, with considerable lag time and under tremendous
financial and technological pressures.
La décennie 1945-1955 fut une période de changement
technique et structurel rapide, ce que Norman Friedman a
décrit comme étant la « révolution navale de l’après guerre ».
Cette période marque l’abandon des stratégies d’escorte au
profit de concepts tels que l’attaque à la source, la barrière
océanique et le recours aux systèmes de détection acoustique
sous-marine. Des forces modernes et rapides nécessaires àl’accomplissement des diverses missions, et de nombreuses
flottes construites pendant la Seconde Guerre mondiale
étaient devenues obsolètes ou devaient faire l’objet d’une
vaste modernisation. La MRC tenta de suivre l’évolution des
changements de structure et des rôles des flottes britannique
et américaine, qui représentent ensemble la révolution navale
de Friedman, mais avec un retard considérable et sous
d’énormes pressions financières et technologiques.
Through the decade from 1945 to 1955, both Britain and the United States (US)
framed naval forces in response to the new global military threat of the Soviet Union.
In doing so they sought to incorporate rapidly changing technologies and frame
effective strategies within severely constrained naval defence budgets. Beyond
nuclear weapons, they faced the world’s largest submarine force, and a slowly
developing surface navy. Through this period of rapid technical and structural change,
a period described by Norman Friedman as the “postwar naval revolution,” mostnavies of the NATO western alliance relied on Britain and the United States to indicate
the proper role and composition of a navy in the nuclear age.1 According to Friedman,

the British and American navies came to denigrate the role of general escort and anti-
submarine forces in favour of forces required for offensive operations. This was a
restructuring of forces shaped largely in response to the fast submarine, guided missile,
and jet aircraft. Because of the inherent difficulties of intercepting these forces near
their intended targets, both the RN and USN adopted strategies and structures that
equated sea control with power projection missions. Following Friedman, this marked
the shift away from escort strategies to concepts such as attack-at-source, ocean
barrier, and the reliance on undersea sound surveillance systems.2 The fast modern
forces required for these various missions rendered many fleets built during the
Second World War obsolete or at best in need of extensive modernization.
Whether or not these trends affected Canada’s navy cannot be determined from
Friedman’s account, because he did not address it. Canada’s response to the
postwar naval revolution is the subject of this paper. As will be demonstrated
below, the RCN attempted to parallel the changes in fleet structures and roles that
combined constitute Friedman’s naval revolution; it did so, however, with
considerable lag time and under tremendous financial and technological pressures.
That the following period, from 1955 to 1964, was a tumultuous era for Canadian
defence policy is well demonstrated. But accounts of this period have tended to
concentrate on issues of continental air defence, particularly the NORADagreement, the cancellation of the Avro Arrow, and the indecision and deceit of the
Diefenbaker administration’s acquisition of nuclear weapons.3 Undeniably this
issue largely determined the election of 1963. Still, accounts have focused on
Diefenbaker being cast from office and the fundamental reforms and reorganization
of Canadian defence policies and forces under the Liberal government of Lester B.
Pearson. These large issues were not without consequence for the RCN, which
after all was dissolved under the direction of the incoming Minister of National
Defence, Paul Hellyer. Although these issues would affect the RCN, the primaryfocus of this essay is fleet planning within the RCN up to that point.
An overview of the entire postwar period, from 1945 to 1964, could be
constructed according to several epochs: from the initial down-sizing of the
fleet; through the beginning of the Cold War and the founding of NATO; the
Korean War; the development of nuclear deterrence strategy; to unification.
However one chooses to compartmentalize the account there are several key

2 Friedman is arguably remiss in not assessing the internal institutional pressures for the adoption of offensive force postures.3 Representative of these themes are Joseph T. Jockel, No Boundaries Upstairs: Canada, the United
States, and the Origins of North American Air Defence (UBC Press, 1987); J.L. Granatstein, Canada

turning points. Although the following account is largely monochromatic and
narrowly focused, the RCN’s response to the postwar naval revolution lends
itself to the following periodization. The first and longest period, 1948-54, is
one of hasty birth and specialization. The second period matched financial
austerity with rapid technical change: the years 1955 through 1961 witnessed the
increased specialization of the fleet in ASW operations in accord with allied
strategies, sound surveillance systems, and a rapidly changing submarine
menace. The RCN’s efforts to respond with “better ships but fewer ships” and
comply with the “come-as-you-are” war scenario of MC-48 came in the face of
extreme financial austerity, but rapid technological change.
The third period, from late 1960 to early 1963, brought short relief to that austerity.
In the expectation of increased money, the RCN tried to reconstitute a balanced
surface capability. The budget increases promised under the MC-70 concept,
however, did not formally encourage RCN participation in the forward maritime
strategy that the primary navies of the alliance had come to substitute for tactical
ASW operations. Instead, tactical ASW in the western Atlantic remained the only
accepted raison d’être. Efforts by the RCN to re-invent itself and create a new
balanced fleet capable of contributing to UN actions or limited war must also be
seen as an effort to create a fleet capable of contributing to forward operations in
the eastern Atlantic. Certainly there were efforts to manipulate the government intoallowing a force structure able to contribute to those operations – witness the
pressure by SACLANT for a second carrier and the General Purpose Frigate (GPF).
In the fourth phase, coinciding with the initial steps taken by Paul Hellyer in
1963 and 1964 to integrate the armed forces, retrenchment and austerity moved
the RCN back into its strictly ASW role in the western Atlantic. The subsequent
steps taken by the navy to restore its mission flexibility following this period
have not been addressed.
In 1961 the RCN had more than sixty warships in commission. It was a sizable and
modern fleet of which many were proud. As Vice-Admiral Herbert Rayner, the
Chief of the Naval Staff, explained at the time: “All efforts are directed towards the
support of the fleet –for it is the fleet that is the true expression of the Navy’s
worth.”4 The vessels included the aircraft carrier Bonaventure, fourteen modern
Canadian-built destroyer escorts of the St. Laurent and Restigouche classes, and a
number of war-built but modernized vessels, including eleven destroyers (seven of the powerful Tribal class, the remainder “emergency-built” classes) 5 and eighteen
frigates of the Prestonian class. A submarine on loan from the USN operated on the

Pacific coast and another two from the RN operated on the Atlantic. The RCN fleet
included ten minesweepers, two escort maintenance ships, and seven smaller craft.
In addition there were over one hundred auxiliary vessels, ranging from research
ships to oil scows and yard craft. The RCN provided three first-line air squadrons
consisting of CS2F Trackers, Banshee fighters and anti-submarine helicopters.
Four other squadrons engaged in training and evaluation duties. Nearly fifty-one
per cent of its uniformed personnel were at sea, a very high sea-to-shore ratio in
comparison to other NATO navies. Building in Canadian shipyards were several
destroyer escorts and the 22,000-ton tanker-supply ship Provider .
Although the fleet may not have been the true measure of the navy’s worth,
addressing the changing composition of the fleet helps foreshorten discussion of
how the RCN faced the postwar naval revolution. At the same time, by 1961 the
fleet’s continued existence was in doubt. Much of the RCN was approaching
block obsolescence. The carrier required replacement before 1975, and the eleven
war-construction destroyers and eighteen frigates were due for retirement before
1970. Bi-lateral agreements under the Canada-United States Regional Planning
Group (CUSRPG) for the defence of the Pacific coast and NATO multi-lateral
arrangements for the Supreme Allied Command Atlantic (SACLANT) committed
Canada to providing twenty-nine anti-submarine warfare escorts to SACLANT
and fourteen to the Canada-US region. With so many vessels requiringreplacement, the RCN would have a net deficiency from agreed force goals of
twenty-three ships by 1970. Living up to that commitment would require a
continuing ship replacement program. The navy largely determined what types of
vessels it required, but obtaining the funding to build ships entailed many others.
As one former insider has recalled, the power to shape the fleet was in the hands of a
very small circle of men.6 The Naval Board bore responsibility for establishing naval
policy. Unlike its namesake created during the Second World War, which included acivilian deputy minister responsible for financial and administrative oversight, the
Naval Board from 1957 consisted of seven senior naval officers: the Chief of the
Naval Staff, the Vice-Chief, the Navy Comptroller, the Director of Personnel, the
Assistant Chief of Naval Staff (Plans), and the Assistant Chief of Naval Staff (Air &
Warfare). These last two members controlled the two functional directorates of the
Naval Staff responsible for force planning and reported to the Vice-Chief of the Naval
Staff. The coordination of technical, financial and operational requirements was
facilitated through the Programme Policy Coordinating Committee,7
chaired by the

Vice-Chief, which vetted most proposals moving forward for consideration by the
Naval Board. If a collective biography of the Naval Board through this period were
to be prepared, it would demonstrate that almost every member had considerable sea
combat experience, ranging from small ship ASW operations to large fleet unit
bombardment missions and even carrier operations. Most had withstood the test of
war and many experienced their war far from Canadian home waters – this despite
the pre-war policy of preparing the navy primarily to operate “over here”. Most had
direct experience of the darkest days of the Battle of the Atlantic and Canada’s hastily
constructed small ship navy. Those shared experiences influenced greatly their desire
to remain technologically advanced and prepared to operate across the great global
seas that admit no artificial boundary. In a future war, as in the last, the Navy would
have to be able to go to the fight.
Despite these shared experiences and perceptions, there remained considerable
leeway to argue about the composition of the RCN. Moreover, fleet planning for most
of the period in question involved making repeated compromises between new
technology, new commitments, and simply maintaining commitments. Simply
maintaining commitments during the period from 1955 to 1960 proved exceedingly
difficult. To illustrate the nature of the problem requires identifying the primary
double bind placed on fleet planning through those years, namely keeping abreast of
the technologies required for a changing NATO maritime strategy, within the direfinancial strictures placed on the Department of National Defence in the late 1950s.
Reflecting the financial problems and priorities of the government, the naval
appropriation was progressively reduced from $326 million in 1957 to $271 million
by 1961. In real dollars the naval budget in 1961 was only nineteen per cent greater
than it had been in 1951. But within these declining estimates RCN personnel
strength increased from 13,500 to over 20,000, and the size of the fleet had trebled
since 1950. Technological changes compounded the effects of the financial strictures.
At NATO’s inception, the large submarine fleet of the Soviet Union posed the
primary naval threat. In 1948, Cabinet authorized the first postwar naval
building program, comprising an arctic icebreaker, three modern ASW escort
frigates, and several small harbour craft. The ASW frigates (the lead ships of the
St. Laurent class) were to be ultramodern ships of Canadian design and
manufacture, capable of locating and destroying the advanced type of U-boats
that Germany had been on the verge of bringing into service in the closing
months of the war.8
Most of the technologies that would have allowed theseboats to operate with near impunity in the North Atlantic were known to have
been captured by the Soviet Union. Following the Chinese intervention in the

Korean War, Canadian Cold War rearmament moved into full swing, with an
increase in the scale and scope of the St. Laurent building program and the major
refit of the Tribal class destroyers and the rechristened Prestonian class frigates
for escort and ASW duties to fill a glaring gap in Canada’s ability to patrol its
coastal areas. Further, the government placed orders for an additional seven
slightly modified St. Laurents (renamed the Restigouche class), all joining the
fleet over the course of 1955-59.
The construction of these vessels proved a major technological feat for
Canadian industry, but the perceived likelihood of general war distracted the
government’s attention from matters of ultimate cost.9 Hasty mobilization
measures bore financial consequences for the future. As the minister of defence
during the Korean era mobilization, Brooke Claxton, discovered shortly before
leaving office, the cost of sustaining the Canadian air commitment alone
promised to require 25 per cent of the department’s budget for the next seven
years.10 As for the RCN, once Canada had committed itself to supplying a set
number of vessels to NATO, that number received a degree of inviolability in
naval planning. The original contributions to NATO for SACLANT and to the
forces under the CUSRPG for Pacific defence had not been based on any cold
calculation of what forces were essential, but rather on what forces Canada
could quickly make available. Canada’s army and air force commitments weresimilarly premised on filling an immediate gap. The costs of sustaining those
commitments through the long haul soon threatened to overwhelm the
government’s financial resources.
Fleet planning within the resulting constricted budget was further complicated
by three developments: NATO naval strategy was changing; the submarine threat
was increasing; and many of the vessels brought into service were expected to
be obsolescent by the mid-1960s. The problem of ship replacementconsequently plagued naval planning from 1955 to 1963.
The efficacy of escort and tactical ASW operations in the age of thermonuclear war
faced serious reconsideration within NATO. Between 1955 and 1962, two
fundamental restatements of NATO’s defensive strategy were made that sorely
tested the RCN’s capacity to respond. The first of these came with the adoption in
1954 of MC-48 marking NATO’s “massive retaliation” reliance on thermonuclear
weapons. The second key policy statement came with promulgation of the MC-70war fighting doctrines aimed at keeping deterrence credible by providing standing
combat forces capable of combat below the nuclear threshold. The debates

surrounding the origins of this policy statement in 1958 need not delay us.11 What
is important for discussion here is the “new look” and then the “new new look”
capabilities the RCN framed in response.12 In short, the escort and ASW strategies
that were clear, unambiguous missions at NATO’s inception waned in importance.
The Chief of Naval Technical Services framed the first guidelines for fleet
planning during this period. Given the anticipated slow or negative growth of the
annual naval budget, Rear-Admiral J.G. Knowlton argued that the RCN adopt a
policy of “fewer ships... but better ships....” 13 While the full implications and
operational requirements were being developed for the support of the MC-48
war concept, the planned fleet replacement building program was postponed. To
replace vessels retiring from the fleet was expected to require a building
program laying down four new ships each fiscal year from 1957 to 1960,
followed by two ships a year from 1960 to 1966/67.
Operationally, the role of ASW forces was no longer clearly one of facilitating
passage on the high seas. For the Navy this meant no longer preparing simply
to re-fight the Battle of the Atlantic. Instead two clear missions developed. The
defence of continental North America now entailed preventing the approach of
Soviet submarines capable of launching nuclear missiles. From late 1954 the
RCN participated in the American development of an extensive under-watersound surveillance system (SOSUS), codenamed project CAESAR.14 For the
CAESAR line to secure the strategic approaches to North America, naval forces
and maritime patrol aircraft were essential for responding to SOSUS contacts
and localizing the submerged threat. A fleet capable of exploiting SOSUS
contacts required greater endurance, speed and improved weapons systems.
The concept of operations in the North Atlantic, in support of SOSUS, required
RCN ASW forces to patrol an area approximately 700 by 300 miles, sufficiently

inshore system, which SOSUS eventually replaced.

far from landfall to negate the range of Soviet missiles.15 To cover the patrol
areas, ships were to operate in pairs, with twenty-four ships required to cover the
search area. Given that number of ships, one hour and fifty minutes would be
required to respond to a SOSUS contact for vessels capable of 27 knots (that is,
the St. Laurent class) or two hours and fifteen minutes for ships of 18 knots
(Prestonian class). These operational requirements highlighted some of the
deficiencies of the current destroyer escort forces. The RCN expected to have
fourteen 27-knot St. Laurent/Restigouche destroyer escorts (DDEs) and four
Tribal class destroyers in service by the end of 1958. 16 There were eleven other
escorts in the fleet (four Tribals and seven Prestonians), but they possessed
neither the speed nor ASW gear suitable for these missions. As well, all the
Tribals and Prestonians were due for retirement by 1970. To achieve the
required twenty-four long-range patrol vessels, six additional ships were
required. Further, to keep ships operating at maximum efficiency within the
patrol areas, two tankers were essential for the Atlantic coast and one for the
Pacific.17 Obtaining vessels for these various missions became the priority of the
ship replacement plan.
However, the defence mission in the western Atlantic was growing quite distinct
from the operational methods being contemplated for the eastern Atlantic. The
maritime strategy shaping the British and American navies required thedevelopment of balanced fleets, based on carrier task forces, capable of offensive
operations against the major Soviet naval bases. As well, ASW barrier operations
were being developed. These entailed securing various choke points through
which Soviet naval forces would have to pass to gain the high seas and North
American approaches. The RCN did not restructure itself to participate in the
strike operations against the Soviet Union, but it had a long-standing commitment
to contribute one aircraft carrier and six escorts for operations under SACLANT
control. In keeping with the changing focus of proposed operations, the carrier’sarea of operations progressively moved into the eastern Atlantic.18
The ability to localize and engage modern submarines became a pressing
concern for two reasons: an unanticipated failure of strategic surveillance
Hennessy: The Postwar Naval Revolution 151
15 In 1956 that range was only 200 nautical miles, but by 1960 it was judged to be between 1000 and1500 nautical miles. See, “Some Factors Pertinent to the MC 48 War Concept”, esp “Annex I – ForceRequirements for the Support of Sound Surveillance Systems,” memo Director Naval Plans to ACNS(Plans), 14 February 1956, LAC, RG 24, Acc 83-84/167, box 457, file 1650-26, vol 15.16 If there were one helicopter per two ships, then not more than forty minutes was required to reach the
DATUM (submarine’s estimated position) point. As for maritime patrol aircraft, maintaining three oncontinuous patrol would give a time on datum of 40 minutes. With those performance requirements, afleet of 40 Neptune patrol aircraft was required to provide twenty-four hour patrol.17 “Annex I – Force Requirements for Support of Sound Surveillance Systems,” LAC, RG 24, Acc 83-84/167, box 457, file 1650-26, vol 15.18 These forces were to be stationed at Brest and Milford-Haven in the event of hostilities, and wouldoperate at the discretion of NATO’s Supreme Commander, Atlantic, SACLANT.

systems; and the improved capabilities of Soviet submarines. Of immediate
concern was the advent of the Soviet Union’s missile carrying submarine
program. The success of the nuclear-powered submarine USS Nautilus in
travelling under the polar ice-cap in 1957 demonstrated to the Naval Board both
the viability of the propulsion plant and that Canada’s northern waters were no
longer immune to submarine operations. The potent combination of nuclear
missiles in nuclear submarines proved a spectre that the Chief of the Naval Staff
explained to the Chiefs of Staff Committee “left anti-submarine warfare far
behind....”19 Further, the ability of the Soviet Union to sortie a large number of
long-range boats was demonstrated during the Cuban missile crisis, when from
23 October to 15 November 1962, some 136 Soviet submarines appeared within
proximity to the Canadian area of responsibility in the Atlantic.20 The anticipated
solution – the SOSUS deep-water sound surveillance system – became
operational in 1957, but did not live up to expectations.21 As late as November
1961, it is clear that SOSUS remained virtually unable to detect Soviet
submarines. The Vice-Chief of the Naval Staff informed the Navy’s senior
officers, “we have virtually no ability” to stop missile firing submarines.22
While studying the ASW problem the Naval Board authorized reductions in the
fleet and declined additional missions for the Navy. After long debate, the Naval
Board voted to dispose of the two cruisers Ontario and Quebec. Though onlybeing used for training missions, the cruisers had been promised to SACLANT for
operations in the eastern Atlantic after mobilization. But the cost of maintaining
that commitment threatened to expend funds that were more urgently required for
addressing the submarine threat in the western Atlantic.23 In the name of economy,
the fleet’s general service capability was further reduced when the navy’s only
icebreaker, HMCS Labrador , was transferred to the Department of Transport.24

19 At one point the Americans sought Canadian adoption of new rules of engagement that would have
authorized ship’s captains to force a vessel within or in proximity to territorial waters to the surface byfire if necessary. Although the Canadians prevailed in stating such a response was unacceptable to theCanadian government it illustrates the level of concern: Navy Board minutes, 592-6, 8 April 1959; andRaymont collection, memo Chief of Naval Staff to Chairman, Chief of Staffs, “RCN SubmarineProgramme”, 18 November 1959, DHH 73/1223 series 1, file 379.20 “Prediction of Operational Exposure Periods in ASW,” in ASW Operational Research Team, ClosedCirculation Report, cited in Tony German, The Sea is at Our Gate, 272.21 For instance, in late 1958 the RCN responded to a submarine operating in conjunction with Soviettrawlers, detected by SOSUS some ten miles off Shelburne, Nova Scotia. The vessels took five hoursto reach the contact datum point. Six vessels conducted the search, but with their sonars limited todetection ranges of about 2000 yards (a range only marginally better than ones obtained during theSecond World War), only a twelve square mile search area was covered before the hunt terminatedunsuccessfully: message to Naval Secretary from Canadian Maritime Commander, Atlantic, “Analysisof the Operations, September 7 and 8, 1958, analysis of contact P-86,” 14 December 1958, LAC, RG

Additionally, in focusing on the submarine threat in the western Atlantic, the Navy
Board declined participation in an American plan to extend the Distant Early
Warning radar system at sea.25 And a Canadian contribution to ASW barrier
operations closer to the Soviet Union, for instance in the Greenland-Iceland-
United Kingdom (GIUK) gap was similarly declined, so as to allow concentration
of resources in the western Atlantic.26
Before any construction began, however, the Liberals were turned from
office. The new Conservative government requested a review of the
proposals before finally giving authorization on 8 August 1957. Finally,
faced with the need to replace retiring vessels, and the need to maintain a
basis of skill among the shipyards, four more destroyer escorts were ordered,
with an additional two authorized the following year.27 For the first four
vessels the infelicitous name “repeat Restigouche” gave way to the
designation “Mackenzie class” – even though they were not the Mackenzie
class as originally designed. The final two repeat Restigouche vessels also
emerged from the shipyards under a new name, the Annapolis class. During
construction, their design under-went substantial modernization,
incorporating those features prepared for the St. Laurent class modernization.
Although the St. Laurents only really joined the operational fleet from about1955 (having been designed in 1948, and laid down in 1949) the pace of
technological change had rendered them nearly obsolescent. They had barely
become operational when a major modernization program was first mooted. This
included incorporation of a helicopter hanger and flight deck, and the
installation of the Canadian designed variable depth sonar (VDS). 28 The potential
of the VDS and helicopter were recognized very early by the RCN. Consisting
of a large active sonar towed array capable of being lowered through the ocean’s
distinct surface temperature layers that particularly disrupted sonar effectivenessin the western Atlantic, the VDS had by late 1958 achieved effective active sonar

same area previously demanding six. After a period of design development and
sea trials their incorporation into the fleet was delayed only by the rate of
production and an orderly shipyard schedule.29
The fitting of helicopters and VDS to the original St. Laurents was undertaken during
their mid-life refits,30 but the modernization program had been in planning since
August 1957.31 Authority for an extensive modernization program came with little
debate because it was apparent that the delays experienced in ordering the “repeat
Restigouche” vessels had threatened to seriously reduce the improvement of the fleet.
The Chief of the Naval Staff gained authority to plan the modernization program after
a private meeting with the ministers of National Defence, External Affairs, and
Finance.32 Once the minister authorized preparation for a major modernization
program, studies commenced in 1958 that focused on improving the ASW
effectiveness of the fleet.33 These studies demonstrated fleet effectiveness would be
greatly improved by the deployment of submarines, helicopters and fixed wing
aircraft working in combination to support the SOSUS barrier. Improving the on-
station time of the ASW vessels was judged critical to meeting the increasing
operational requirements of the ASW forces, and to this end the first of three fleet
replenishment/tankers was undertaken.34 Beyond improving the on-station time of the
fleet, drastic improvements were sought in the ASW vessels. Present forces required
immediate improvement,35 leading to the modernization program that saw theconcepts tested on the converted wartime construction destroyers Sioux and Crescent .
Less immediate was the solution to the shape of the next class of ASW vessels.
Submarines, it was argued, could be incorporated into the annual estimates for

1958/59.36 If the RCN was to create a submarine branch focussed on ASW it was
fair to ask what future surface combatants should have as their primary role. But
in considering the usefulness of surface escorts the fleet anti-aircraft capacity
also required consideration. Maintaining an anti-air capability while improving
the ASW effectiveness of the fleet and meeting the replacement schedule
evolved into a long-running question for naval planners, and could not be
disentangled from the submarine building initiative.
Allied navies were demonstrating that submarines promised to make the most
effective means of hunting other submarines. As well the development of
nuclear submarines by both the United States and Great Britain saw Canada’s
major naval allies choosing a technology that would be difficult but not
impossible for Canada to acquire. Certainly Canada explored the possibility of
indigenous production of nuclear boats, but eventually settled upon the
compromise purchase of the conventional Oberon class submarines that served
until the late 1990s. At the 564th meeting of the Naval Board on 2 April 1958, the
requirement for nuclear submarines was agreed. A detailed feasibility study on
Canadian construction facilities was undertaken by the Nuclear Submarine
Survey Team, which experienced no luck in securing detailed information from
the United States on either the hull or propulsion characteristics of their vessels
in 1958. In early 1959, a “Scope and Means” agreement was negotiated with theUnited States Navy and Atomic Energy Commission, allowing the exchange of
some detailed information. The final report of the Survey Team was completed
by July 1959, and an extensive survey of Canadian shipyards and discussion
with manufacturers concluded Canadian industry could build nuclear
submarines, the only limiting considerations being time and cost.37
These too-generous caveats prompted the Chief of Naval Staff, Vice-Admiral
H.G. DeWolf, to call into question the findings of the survey. For theconservative cost estimate of one nuclear submarine, the RCN could gain three
to five conventional submarines.38 As it was then argued, the latest conventional

$9 million in the UK; see “RCN Submarine Programme” 1959, 2; for the entire Nuclear Submarine Survey,see DHH 79/246 project files, L-1 and L-2. However, the ability of the nuclear submarine to generateelectricity was also of great benefit: while Britain and the United States were employing submarine-mountedpassive sonar with increasing effect, achieving quite exceptional detection ranges (in the order of 125 miles),active sonar was still considered an essential requirement, even if the power requirements of long rangeactive sonar could quickly drain a conventional submarine’s batteries. At the time a good range for activesonar was 10 miles, with some demonstrated capacity out to the first convergence zone (35 miles).

boats possessed many of the same operational advantages as other submarines,
the only real disadvantage being submerged endurance and speed – limitations
that eventually proved decisive against an immediate program to build nuclear
boats, in light of the tremendous cost differential.
These were the major points of DeWolf’s criticism. The tactics and training for
ASW had yet to take account of the speed advantages of nuclear boats. Most
tactics and methods had been developed against conventional submarines with
submerged speeds of 3-5 knots. Against such slow targets ships were given a
five-to-one speed advantage and aircraft a forty-to-one advantage. But with
nuclear boats capable of high-speed operations in excess of 20 knots, the surface
craft often had a speed disadvantage, and maritime aircraft were reduced to an
approximately seven-to-one advantage. These operational conditions were not
widely known at the time, and for the minister speed proved the decisive issue.
As he saw it high speed was not essential for “defensive A/S operations in the
Atlantic.” Consequently, the Chief of Naval Staff recommended that, unless
additional funds could be made available to the Navy to meet the cost of
building nuclear boats, conventional submarines should be undertaken on the
basis of equal priority with the surface vessels of the planned replacement
program.39 However, until the submarine program was settled the surface fleet
replacement program was also delayed.
In recognition of the demise of the nuclear program, the RCN made an interim
submission to the minister on 27 October 1960. The Chief of the Naval Staff
compared the costs of building six US Barbel class conventional boats in Canada
(at $164 million) to building six British Oberon class boats in the United
Kingdom: of all available conventional submarine designs only the Oberons
approached the operational profile of the Barbels, yet for the same money the
Oberons would allow the Navy to obtain an additional four surface ASW vessels,at the cost of $22 million dollars each. Although the CNS concluded the Barbels
would make the most effective ASW force, the usefulness of additional ASW
ships could not be discounted.
In the absence of ministerial decision the RCN persisted with the Barbel
proposal, taking it to the Chiefs of Staff Committee on 18 May 1961. The
program for ship replacement then discussed included not only the six

submarines, but also an eight-vessel General Purpose Frigate (GPF) program.
Had both programs been adopted, the resulting fleet would include twenty-six
ASW escorts, nine submarines, and eight general purpose frigates. Once the
submarines and GPFs were completed the RCN would commence a six-vessel
ASW frigate program. This building program was markedly more ambitious
than that proposed to the Minister only nine months previously.
What were the origins of the modified program? The most important event was
the promise of additional money. In accordance with NATO strategy, articulated
under the MC-70 policy, the federal Cabinet agreed on 22 March 1960 to
increase the Canadian defence budget from its present level of approximately
$1.5 billion annually to $2 billion by fiscal year 1964/65.40 Within NATO
strategy the MC-70 concept entailed a policy of forward engagement for
maritime forces as developed by the RN and USN. Tactical ASW in the western
Atlantic was troubling for the Navy, but was neither the true end of NATO
strategy (which was to deter aggression) nor the most efficacious means of
counter-acting Soviet submarine operations. Keeping the Bear in its pen was
better than dealing with it on the loose – at least that is where SACLANT’s naval
strategy was pointed, whether or not Canada participated.
Requirements for support of MC-70 had influenced NATO fleet planning since1958, but Canada did not move to increase its participation in forward
operations. Subtle pressures through SACLANT had been brought to bear on
the cabinet for the deployment of a second Canadian aircraft carrier. Whatever
the cabinet’s reluctance to contemplate contributing to strike operations, the
financial requirement proved decisive in killing further talk of a second carrier.41
There were enough financial, operational, and political difficulties dealing with
the submarines in Canada’s coastal area of responsibility.
Within the Navy, the long delays in obtaining approval for any fleet replacement
plan had caused grave concern. Concern also developed over the specialization
in the ASW mission. General purpose forces had been pared away in pursuit of
a better ASW force at a time when allied navies were changing their approach to
the submarine problem by building strike forces. Once it appeared to the naval
staff that some form of submarine program would be authorized, attention turned
to developing designs for follow-on surface vessels that would preserve the
general surface capacity of the fleet.42

approval of any submarine program uncertain, the naval staff still listed a low
cost “austerity” ASW frigate as the top priority building requirement. 43 But then
it was an either-or proposition: either submarines or ASW frigates.44
However, the replacement program sent forward on 18 May 1961 discarded the
austerity frigate, and sought instead permission to undertake simultaneously the
construction of submarine and new surface vessel programs. These were elaborated
in the Ad Hoc Report on Naval Objectives45 sent to the minister in December 1961.
The Report bore the hallmark of the incoming Vice-Chief of Naval Staff, Vice-
Admiral Jeffry V. Brock. By his own later admission, it was the “first opportunity
to put my own hands on the helm after all these years.”46 The Brock Report
identified most of the recent trends in naval technology confronting the Naval
Board. Transitions in air, surface, and sub-surface operational requirements were
portrayed as calling for many new surface and sub-surface vessels.
In sum, the report endorsed a fleet based on the concept of “cheap and many.”
To forestall serious deficiencies in the Navy’s escort forces, the Brock Report
called for a replacement and modernization program. The future fleet required
replenishment vessels to allow the fighting units to stay within their patrol
areas longer. The fighting fleet required six Barbel class conventional
submarines and eight general purpose frigates. These frigates would replacethe Tribals and were to be capable of shore bombardment, limited air-defence,
and ASW missions. To replace the old, slow, ocean escort Prestonians as well
as the aircraft carrier Bonaventure, the Brock Report called for construction of
a number of “heliporters”: frigates only marginally larger than the
Prestonians, but capable of operating three helicopters in the ASW role. These
heliporters also could be converted to provide moderate troop lift capacity –
something that would be greatly reduced with the retirement of Bonaventure in
1975. Finally the RCN was to continue an extensive research program intounconventional ASW craft, such as hydrofoils and hovercraft. This new
construction, argued the Report, could be funded through a modest increase in
naval appropriations. The funding goal was one per cent of the Gross National
Product annually for fifteen years.47 In dollar terms, the fifteen-year program
called for naval capital expenditures to increase from $275 million to a peak
in 1972 at $525 million.48

The developing submarine threat, the limitations of current underwater
surveillance techniques, and the almost prohibitive expense of modern surface
ASW vessels, combined to suggest the force requirements and building program
outlined in the Brock Report. Although the Brock Report is given to diverse
interpretations, 49 the acceptance of the Report by the entire Naval Board
demonstrated a shared belief that, unlike most other NATO navies, the RCN
should not (or politically could not) restructure around carrier task groups or
strike forces. That it included a call for the maintenance of a general purpose
capacity does not contradict that trend.
The genesis of the GPF program illustrates these points. In developing the
design, the naval staff turned to the characteristics of new general purpose
designs being developed by the RN and USN.50 Both these navies developed
these vessels in light of new missile technologies and a concept of operations
that illustrated the precarious place that strictly ASW forces occupied in their
strategies. From the late 1950s, both navies increased their reliance on strike
operations. For their attack-at-source missions, or the imposition of near-source
ASW barrier operations designed to hold Soviet submarines in the eastern
Atlantic, surface fire and anti-aircraft forces were essential. Their general
purpose vessels were designed for those operations.
However, in seeking a general purpose Canadian vessel the strike mission was
not a stated goal of the Naval Board. A memorandum from the Director of
Naval Operations indicates at least one primary interest. In light of the
possible acquisition of nuclear weapons51 and submarines, the guided missile
frigate would be far better for morale “than our obsession with the submarine
threat.” The present ASW forces could hold “the thin red line” until relieved
by the submarines.52 Further, the guided missile ships would also improve the
balance and flexibility of the RCN by replacing the aging Tribal classdestroyers. As well, their air defence capabilities would soon be essential for
defence of the Canadian carrier task force. The Bonaventure’s Banshee
Hennessy: The Postwar Naval Revolution 159
49 Some observers regard it as calling for a “quantum leap” in the Navy’s capabilities. In thisinterpretation the Report marks a radical departure from previous naval policy – calling for a return toa balanced fleet for the RCN and a move away from the emphasis on ASW operations. Others portrayit as simply a re-statement of the navy’s primary anti-submarine warfare role, specifying new vesselsrequired to fulfil that role. See, Peter Haydon, “When Military Plans and Policies Conflict: The Caseof Canada’s General Purpose Frigate Problems,” The McNaughton Papers (vol II) (Toronto: CISS,1991), 59; and Brian Cuthbertson, Canadian Military Independence in the Age of the Superpowers
(Toronto: Fitzhenry & Whiteside, 1977), 129-30.50 The RN recently produced a new Tribal class, the Type 81 Frigate, and the USN the guided missileCharles F. Adams class destroyer.51 The possible acquisition of nuclear weapons was under constant study through the late 1950s.However, no major steps were taken to actually retain nuclear depth bombs in Canada or on its warshipsuntil 1964.

fighters, scheduled for retirement in 1962, were not going to be replaced. 53
Consequently, steps were taken to plan the carrier’s conversion into a
commando or heliporter carrier.54 The decision to develop the carrier along
these lines marked a loss for the proponents of carrier aviation within the
Navy. The decision not to retain the fighters marked a step away from
operations in the eastern Atlantic and was closely tied to acquisition of the
GPF.55 Funds not used to replace the Banshee fighters would be turned to new
ship construction.56
In seeking authority for the GPF, two further arguments were marshalled. First,
champions of the General Purpose Frigate pointed to its potential contribution to
United Nations operations, and possible use in brush-fire wars. Although the
Chairman of the Chiefs of Staff Committee had been wary of recommending
construction of the GPF because it threatened to move the RCN toward
participation in strike operations in the eastern Atlantic, the UN and small war
argument won him over.57 The argument was not without merit. Canadian
destroyers were among the first Canadian forces to participate in UN operations
during the Korean War. In 1956, the RCN had transported a Canadian battalion
to Suez for UN deployment. Given the contemporary UN military actions in the
Congo, possible participation in brush-fire crises was not easily discounted. Just
so no one missed the point, a line was inserted into the RCN long term planningguide noting that the “successful deterrent in global war will tend to increase the
likelihood of limited war.”58
The second major argument marshalled in favour of the GPF was the RCN’s
newly developed concept of a balanced ASW force. By April 1961, the Naval
Board had developed the concept of what constituted a modern, balanced ASW
fleet. Their ideal force required one-fifth submarines, three-fifths ASW escorts,
and one-fifth general purpose ships. With Canada committed to provide a forty-three-ship ASW force to SACLANT, the required force mix would yield a fleet
of twenty-six A/S escorts, nine A/S submarines, and eight General Purpose
Frigates – this was the precise mix later included in the Brock Report. 59 Through
circuitous means the naval staff succeeded in having SACLANT recommend just

such a fleet structure to the Chiefs of Staff Committee when generating new
force requirements in support of the MC-70 Medium Term Defence Plan.60
All of these diverse strands came together in the building program proposed to
the Chiefs of Staff Committee in early May 1961. The RCN gained permission
to include the GPF in its annual estimates for fiscal year 1962/63. But unknown
to the planning staff, the RCN instead was approaching nadir. Program planning
and budgeting problems associated with this new program were only part of the
Navy’s undoing. By early 1963, the GPF program estimates had risen from $275
million to $450-500 million, and design refinement was still at an early stage.61
The growing concern of the Department of Finance and the Treasury Board was
soon shared by a new government, after the Diefenbaker Conservatives lost a
vote of confidence in the House on 5 February 1963.
Prevarication by Diefenbaker’s government over the adoption of nuclear
weapons and dithering during the Cuban Missile Crisis raised defence policy as
a major issue in Canadian political circles. The Liberals won the election under
the banner of reform, and the “sixty days of decision” Pearson promised the
electorate heralded a commitment to action and reform. The reforms then set in
train took much longer than sixty days to implement – but the new Minister of
National Defence, Paul Hellyer, turned his immediate attention to the GPFprogram. Program review began in May. In June, all government capital
programs were suspended pending a full review of expenditures. By early
October, cabinet had agreed to cancel the General Purpose Frigate. The
cancellation cannot be explained as simply a response to the expected cost
overruns. Rather it was directly tied to the more fundamental reforms of defence
policy and defence spending undertaken by the new government.
In outlining these cuts to the full cabinet, the Chief of the Naval Staff pointedout that the RCN would effect savings of $280 million as requested by the
minister by taking $197 million over the next two and one half years from
capital programs, the balance to be reduced by cutting the uniformed strength
from 21,324 to 20,500 and removing four Tribal class destroyers from service.
By 1970, the RCN would be reduced to twenty-seven warships, sixteen of
which would be obsolete and overdue for replacement, and with eleven of the
twenty St. Laurent/Restigouche/MacKenzie class vessels lacking the most
effective ASW equipment. The ramifications of the proposed cuts were spelled

out in detail to the cabinet, wrote Hellyer, so that they could adequately judge
the “order of magnitude.”62
The cabinet minutes indicate the prime minister was moved by the passion of the
arguments presented by the service chiefs as they outlined the consequences of
reducing the defence appropriation. But the minutes also record Pearson’s
conclusion: “in order to get public support for the defence programme, there
would have to be radical change in its character.”63 The GPF took the first real
blow in this long process of radical reform. 64
Although the minister’s personal emissary investigating the GPF found it as
capable of effectively contributing to ASW operations as any other unit in the fleet
(or proposed design), the need to reduce the general defence budget drove the
issue.65 The proposed cuts soon sparked the recommendation from the deputy
minister of defence to cancel the GPF and retain the Oberon building program. The
British had already agreed to offset the submarine sale by contributing fifty per cent
of the development costs (some $10 million) to the development of a small drone
aircraft that had “a good prospect of sizable export sales for Canada.”66 The
minister’s recommendation to cancel the GPF and maintain the Oberon building
program did not shield the ramifications from cabinet. Cancellation would yield a
fleet “incapable of meeting current NATO commitments....” There would be no“satisfactory anti air defence for the fleet.” SACLANT considered the move would
reduce the effectiveness of the Canadian carrier ASW group. The twenty-three
surface vessels of Second World War construction would remain in service for
years past their effective life. But as the minister’s memo to cabinet noted, “in view
of the reduced resources available for defence” cancellation had to be
recommended.67 All that remained to be determined was how to sugar coat the pill.
Cabinet turned its attention to this matter on 18 and 22 October. In discussion it
was agreed to state the reduction came as part of a current NATO review of policy,even though the two matters were unrelated. Further, press announcements would
stress that no jobs had actually been forfeit. Lastly, the public statement was
delayed so that the Department of Transport could prepare an announcement that its
shipbuilding program would be expanded. The expanded DOT program and
cancellation of the GPF were announced on 25 October 1963.68 Although these cuts
were the first of major reforms to come, Minister of Finance Walter Gordon noted

the excellent job Paul Hellyer was doing in reversing the upward curve in defence
expenditures, adding enigmatically that the move was all the more difficult in light
of it being done “before long-term policy decisions were reached....”69
But for the RCN it was portent enough. Operation “cut back” continued into
1964.70 Efforts by the naval staff through early 1964 to devise a plan for the
future shape of the fleet maintained the assumption that the RCN should be
primarily an ASW navy, but also have a capability for UN peacekeeping
operations and limited war commitments.71 The lack of suitable air-defence
capabilities remained a pressing concern, as did long term planning for the
introduction of nuclear submarines and helicopter carriers.72 But running
parallel to those studies were others being prepared for the minister as he set
about to draft the 1964 White Paper on Defence. However, even the financial
predictions prepared in those studies would prove too optimistic. Where the
reductions would cease remained unknown on 1 August 1964, when in
accordance with the White Paper, the Chiefs of Staff Committee, independent
service heads, Naval Board and Naval Staff were struck down as the first step
in integrating the Department of National Defence. Operation cut back
continued – how the now-headless Navy fared after 1964, however, is beyond
the scope of this paper.73
The rate of technological change being experienced by the RCN through this period
is perhaps unprecedented. That the RCN faced the demands of the postwar naval
revolution with dispatch and professionalism is not in doubt. That efforts were made
to stay abreast of all the technical trends and to do so without increasing dramatically
the naval appropriation called for numerous trade-offs. Aware that major increases to
their budget would not be forthcoming, the Naval Board and lower levels of the Naval
Staff held many pressures in check. The institutional pressures for more aircraft,
another aircraft carrier, nuclear propelled submarines, and surface-to-air missileequipped frigates were generated as often by the Soviet threat as by reading trends in
allied weapons development and capabilities. Even so, efforts were made to employ
supply-side pressures on the government through manipulating SACLANT’s force
requests – first for an additional aircraft carrier and then the General Purpose Frigate.

However, only the appreciable demand-side pressures resulting from the
increased Soviet submarine presence and the demand-side pressure imposed by
a changing NATO strategy resulted in the Navy apparently achieving real
increased funding – as witnessed by the announced acceptance of the submarine
and GPF program. That those systems’ designs reflected the latest of allied
technologies and capabilities must be accepted. That they had been designed to
support a forward defence strategy not accepted by the government proved only
a short-lived problem – solved by the Liberal’s reforms that in short order
eliminated the RCN as an independent service.
