ROYAL CANADIANThe Royal Canadian Navy iscelebrating its 50th anniversary.Canada's Navy officiallycame into being when, on 4thMay, 1910. Royal assent wasgranted to the Naval ServiceAct. That same year two protectedcruisers, the NIOBEandRAINBOW, were acquiredfrom the Royal Navy.Ships of the Royal CanadianNavy have served in threewars. During the First WorldWar the Canadian naval contributionwas about 9.600 officersand men and 100 ships.During the Second WorldWar the Royal Canadian Navyexpanded to 392 armed shipsand 95,000 officers, men andNAVYWrens. Canada's major navaleffort being devoted to theBattle of the Atlantic.Canadian destroyers servedin the Far East throughout theKorean War.This 50th anniversary yearI960, finds the Royal CanadianNavy at its greatest peacetimestrength, with Ii2 warships incommission and with 20.604officers, men and Wrens onfull-time duty, and 3.550 in theactive Royal Canadian NavalReserve. Some 49 per cent, ofthe Royal Canadian Navy personnelare at present servingon board ship.R.C.N. JETS TESTED.Six Banshee jet-fighters ofthe Royal Canadian Navy,armed with Sidewinder missiles.convincingly demonstratedtheir destructive power byshooting down five target-aircraftin an exercise designedto test the effectiveness of theBanshee-Sidewinder combination.The firings took place overthe sea on the missile range ofthe Royal Aircraft Establishmentat Aberporth, Wales. Thetargets were Firefly VIM aircraft.flown by remote control.Six missiles were fired at asmany targets and five of thedrone aircraft were splashed.The operation was carriedout by aircraft of FighterSquadron K70.The Governor-General, Lord Donroaall. and Lady Dunronall, with Aetinf/Leadlni Seaman Brian Boad ofH.M.A.8 VAMPIRF. liid Chief F..R.A Chartea Cunningham of HM.AS MELBOURNE and Mm. Cunninghamat an Investiture for R.A.N, men at Government House, Canberra.22THE NAVYQUEEN'S BIRTHDAY HONOURSHer Majesty the Queen ha* beenfollowing awards:—Knight Commander ofThe Order of the British EmpireVice-Admiral HenryC.B.E.Commander ofMackay Burrell, C.B.,The Order of the BritishEmpireRear-Admiral Kenneth McKenzie Urquhart.Officer ofThe Order of the British EmpireCaptain Stanley Darling, D.S.C. and two bars,V.R.D., R.A.N.R.Member ofThe Order of the British EmpireLieut. Ronald Mervyn Titcombe, R.A.N.BritishVice-Admiral Sir Henry Bvrreil, K.B.E., C.B. Chief E.R.A. Thomas William James Cunningham.The circumstances surroundingthe award to Lieut. Titcombewere:On April 21, 1959, a chopperoperating from Portland (England)ditched about 9 milessouth-east of the ShamblesLight Vessel, in a depth of 170feet.To determine the cause ofthe crash it was essential torecover the helicopter, but thestrong tides prevented the recoveryby wire sweeps andstandard divers.Lieutenant Titcombe, then incharge of the Clearance Divingteam at H.M. Underwater DetectionEstablishment, was consultedoil the use of clearancedivers. In such depths, withfurther complications causedby the swift tides, operatingtime for the divers belowwould be very short.Still further, the ascent mustbe a matter of no more than5 minutes, making decompressionin a special chamber amatter of urgent necessity.The necessary equipment includingspecial inflatable dinghiescapable of operating inrough weather were available,and so Clearance Diving historywas made.It was tin 1 first operationaloccasion that Clearance Divershad performed at such greatdepths and that surface decompressionhad been used, andthe team effort was the mainfactor in the successful recoveryof the chopper.The success of the operationwas largely due to the intelligentappreciation of thesituation, the leadership andthe fine personal efforts ofLieutenant Titcombe.NEW RATE FOR R.N.Among the points that Mr.Orr-Ewing, Civil Lord of theAdmiralty, recently discussedill tile House of Commons wasthe suggestion that a Masterrate, above that of Chief PettyOfficer, be introduced in theRoyal Navy.This rate would bring theNavy in line with the statusand pay of Warrant Officers inthe other services.Mr. Orr-Ewing said that theproblem is now under consideration.July, I960 23
NEW TYPE SONARSignificant Advance in Submarine DetectionA new type of Sonar, known asis being manufactured in CanadaHE new system will enableT warships to lower sonargear through the ocean's thermallayers, thereby overcomingthe ability of submarinesto escape detection in or belowthese temperature strata.Variable depth sonar is theresult of more than 1(1 years'research anil development byDefence Research Hoard scientistsof the Naval ResearchEstablishment at Halifax. NovaScotia.The need for a layer-probingsonar first became apparentwhen German submarines, bothby accident and design, madetactical use of thermal layersduring the Second World War.The upper levels of oceansusually contain layers of. varyingtemperature which form ahorizontally uniform patternmany miles in extent. Theselayers may refract or completelyresist penetration bvsonar transmissions from hullmountedsets.The problem was of particularconcern to the RoyalCanadian Navv because of thepresence of such layers off thecoasts of Canada.Defence Research Hoardscientists and anti-submarinespecialists of the Royal CanadianNavy, Working on theproject together, discoveredthat the problem could be substantiallyovercome by placingtransducers in or below thelayers of varying temperatures.Applied research and developmentfollowed, and theresult was an equipment consistingessentially of a trans-V.D.S. (variable depth sonar)for the Royal Canadian Navy.ducer enclosed in a streamlinedbody which can be towed atvarying depths. The towingcable houses a core of electricalconductors. These transmitsignals to tin* towing ship'ssonar displays and alsn earnelectrical power from the shipto tin- transducer.The concept which led to thedevelopment of variable depthsonar was initiated almostsimultaneously in Canada andthe United States. Close liaisonwas maintained with theRoyal Navy and the I'nitedStates Navy, who also soughtimproved detection methodsalong similar lines. Informationwas shared throughout bythe associated countries, withCanada concentrating 011 specifiedpossible methods as theother countries explored differentbut allied techniques.II. M.C.S. "NEW LIS-K E A R D ". originally an"Algerine" class ocean minesweepersubsequently reclassifiedas a coastal escort,and now again re-rated asa survey ship for bathythermeographicduties, was thefirst ship to be used for experimentaltrials. Repeated testingand modification resulted inimprovement in the performanceof the equipment, and amore sophisticated version ofvariable depth sonar, built byCanadian firms, was installedin II.M.C.S. "CRUSADER," aformer British destroyer nowrated as a destroyer escort.Intensive evaluation producedeffective results and the equipmentwas accepted for servicein the Royal Canadian Navy.MELBOURNESTEAMSHIPCO.

VERSUS SUB.(Continued from page 15)form of warfare, has been asuccession of temporary advanceson each side of thebattle. Now. however, thenuclear submarine has temporarilyoutstripped all conventionalforms of surface and airA/S methods, leaving only allothersubmarine (preferablynuclear) as its logical opponent.What advantages does asubmarine hold over its surfaceand air colleagues? By itschoice of depth it can penetratethe density layers whichare the under-water equivalentof the smoke screen or rainstorm to shelter a hunted submarine.It can chase its quarryunder the polar icefloes. Itsinvisibility, even in these days,gives it a good chance of operatingin enemy held waters,and particularly in the approachesto submarine bases—the most fruitful huntingground of all. Such areas, withtheir inevitable enemy air sujieriority,are unsuitable, to saythe least, for patrol by frigategroups or slow A/S aircraft.As well as having the abilityto remain unseen, the submarinecan stay 011 patrol forweeks or even mouths, maintainingcomplete silence, andmaking the best use of intelligencereports covering a largearea. Finally, rough weathereffectively "quenches" theasdics of surface ships and reducestheir speed superiorityover a conventional submarine.The chances of detection andchase against a '20-knot nuclearvessel are still decidedly slender,even using a combinationof air and surface forces. Anothernuclear submarine, equippedwith homing torpedoes andmodern asdics, has both thespeed and the detection equipmentto deal with its transittingopponent.July.
