RAF Coastal Command RAF Coastal Command was a formation within the Royal Air Force ( RAF ) . Founded in 1936 , it was the RAF ' s premier maritime arm , after the Royal Navy ' s secondment of the Fleet Air Arm in 1937 . Naval aviation was neglected in the inter - war period , 1919 – 1939 , and as a consequence the service did not receive the resources it needed to develop properly or efficiently . This continued until the outbreak of the Second World War , during which it came to prominence . But owing to the Air Ministry ' s concentration on RAF Fighter Command and RAF Bomber Command , Coastal Command was often referred to as the " Cinderella Service " , a phrase first used by the First Lord of the Admiralty at the time A V Alexander . Its primary task was to protect convoys from the German " Kriegsmarine " ' s U - Boat force , known as the " wolfpacks " . It also protected Allied shipping from the aerial threat posed by the " Luftwaffe " . The main operations of Coastal Command were defensive , defending supply lines in the various theatres of war , most notably the Mediterranean , Middle East and African theatres and the battle of the Atlantic . It also served in an offensive capacity . In the Mediterranean theatre and the Baltic sea it carried out attacks on German shipping moving war materials from Italy to North Africa and from Scandinavia to Germany . By 1943 Coastal Command finally received the recognition it needed and its operations proved decisive in the victory over the U - Boats . The service saw action from the first day of hostilities until the last day of the Second World War . It flew over one million flying hours , 240 , 000 operations and destroyed 212 U - boats . Coastal Command ' s casualties amounted to 2 , 060 aircraft to all causes and some 5 , 866 personnel killed in action . From 1940 to 1945 Coastal Command sank 366 German transport vessels and damaged 134 . The total tonnage sunk was 512 , 330 tons and another 513 , 454 tons damaged . A total of 10 , 663 persons were rescued by the Command , including 5 , 721 Allied crews , 277 enemy personnel , and 4 , 665 non - aircrews . After the war , the Command continued Anti - Submarine Warfare duties during the Cold War , to combat the threat posed by the Soviet Navy and those fleets of the Warsaw Pact . Formation and neglect . In 1936 , almost 18 years after the end of the First World War , there was a major change in the Command structure of the RAF . Several Expansion Schemes were heading at such pace to rearm the British military in face of the Nazi threat that " Area " formations were now to be called " Commands " . Fighter and Bomber Areas became Fighter and Bomber Command and Coastal Area was renamed Coastal Command . Its Headquarters was located as Lee - on - Solent . Air Marshal Arthur Longmore , AOC RAF Coastal Area oversaw the renaming and handed over command to Air Marshal Philip Joubert de la Ferté on 24 August 1936 . In March 1935 the threat from Nazi Germany prompted a series of expansion schemes which pushed the number of squadrons up to 163 ( as per Expansion Scheme M , the last before the outbreak of war ) and the number of aircraft to 2 , 549 . But it was never fully implemented , and Scheme F , 124 Squadrons and 1 , 736 aircraft , was the only scheme that ran its full course . It did produce modern aircraft and it made adequate provision for reserves ( 75 percent ) , but again , the bomber forces received no less than 50 percent which averaged 57 percent over all schemes . Maritime air units never made more than 12 percent of British air strength . From a pre - expansion strength of just five squadrons , four of which were flying boats , the figure of maritime squadrons rose to 18 by September 1939 , with a strength of just 176 aircraft . Some 16 of these were allocated to trade defence , but given Trenchard ' s policy ( which was still in place after his retirement ) of developing bombers for the maritime arm which could bolster the air offensive , most were unspecialised for ASW , and the Air Ministry were thoroughly uninterested in any aircraft which fell outside of the bomber function . de la Ferté was highly critical of the Air Ministry ' s attitude to his service . In 1937 several exercises were carried out by Coastal Command in cooperation with submarines against the Home Fleet to judge the surface fleet ' s defence against submarine and air attack . However , despite the experiences of the First World War , no attention was paid to the problem of attacking submarines from the air as part of trade protection measures . Owing to the imperfect ASDIC invention , it appeared the Royal Navy no longer considered U - Boats were a threat to Britain ' s sea lanes . The Air Ministry , keen to concentrate on strategic air forces , did not dispute the Admiralty ' s conclusions and Coastal Command did not receive any guidance from the Air Ministry . The saving grace of both services was the construction of the Combined Headquarters which enabled rapid collaboration in maritime operations . This was one of the few successes in organisation and preparation made before the outbreak of war . When the review of the role Coastal Command was to play in war was assessed in 1937 , the then AOC Frederick Bowhill was informed by his senior Air Staff Officer Air Commodore Geoffrey Bromet that the other two commands ( Bomber and Fighter ) had clear mission objectives while Coastal Command had been given no clear mandate . It was assumed that Coastal Command was to keep sea communications open for merchant shipping and prevent seaborne raids on British coastlines and ports . No mention of U - Boats was made by either man . Both assumed aircraft and surface raiders presented the greater threat in British waters . Thus they followed the Admiralty line that U - Boats were no longer a danger . When Admiral Dudley Pound enquired about aerial assets in trade and commerce defence , Chief of the Air Staff Cyril Newall , replied that there was not enough " jam " [ resources ] to go around and stated it was more advisable to risk losses on trade routes than weaken the RAF ' s ability to protect Britain from air attack and bomb its enemies . In March 1937 , the then Director of Operations Group Captain Robert Saundby , complained that the role for Coastal Command in war , namely supporting the bomber offensive , and second , the support of naval forces along the British coastline , were too limited and was in danger of diverting the Command from its main concern ; ASW . In October the Deputy Chief of the Air Staff ( DCAS ) Air Vice Marshal Richard Peirse confirmed that there was no formal role for the service or location of its units . Peirse did reverse the decision to have strategic bombing support as the primary function . This was changed to trade defence . Coastal Command was only to be used for other purposes if trade routes were suffering little interference and the intensity of air attack on Britain or air attacks on enemy targets , required all available air units for those purposes . However , in December 1937 , the Naval and Air Staffs met again , and changed the priority to North Sea reconnaissance . The Naval Staff insisted that commerce raiders presented the greatest danger , and aircraft could prove decisive only in locating enemy Warships . ASW remained in third place , behind direct co - operation with surface fleets . In December 1938 , this was changed again , and ASW moved up to second priority . In August 1939 , it was moved to first priority . When Coastal Command went to war , its first task was to co - operate with the Navy to prevent enemy vessels from escaping into the North Sea and Atlantic Oceans . Second , it was to provide ASW support where and when it could . These steps are significant as the language indicates a change from passive reconnaissance of enemy warships and submarines , to an active directive which involved the attack of the vessels by Coastal Command aircraft . Since the late 1920s the tension between the air and naval services had declined . It arose briefly again in 1937 when the question of the FAA operational control arose . On this occasion the British Government sided with the Admiralty . Despite a spirited defence of its asset , once the Minister for Coordination of Defence , Sir Thomas Inskip had decided to transfer the arm , the Air Ministry was content to let the matter rest . Any threat to the Air Ministry ' s existence had long since passed , budgetary constraint , and the reluctance to engage in another battle which would waste resources were also factors in the Air Ministry ' s decision not to contest the issue further . However , inter - Service squabbling assured maritime aviation ' s stagnation , especially in shore - based elements . Virtually no co - operation existed in the area of research and development . In the case of Coastal Command , it continued to come third in the Air Ministry ' s list of priorities , after Fighter and Bomber Commands , well into the late 1930s . Second World War . Early war . From its formation in 1936 the Command did not receive the support it required to be an effective naval air service . In September 1939 , Nazi Germany invaded Poland beginning the war in Europe . The Command ' s position was comfortable for the first nine months of the war , the period known as the Phoney War . German submarines were not able to reach the Atlantic unless they undertook a dangerous transit journey through the North Sea and around Britain ' s northern waters , or through the English Channel , which was guarded by the Royal and French Navies . The powerful French Navy was responsible for covering half of the Atlantic shipping routes , and thus contributed half of the Allied forces available . However , the events of April to June 1940 overturned the balance of power , as the Germans conquered Denmark , Norway , The Netherlands , Belgium and France . This allowed the " Luftwaffe " and " Kriegsmarine " to operate from French ports on the Atlantic coast , much closer to the Atlantic shipping lanes . It also put German air power within range of Britain ' s ports on all of its coasts . The advantage now enjoyed by the Germans allowed them to inflict heavy losses to merchant shipping supplying food and war materials to Britain , potentially threatening to starve Britain . While merchant shipping was suffering these high losses , Coastal Command had proven ineffective at countering air or sea attacks on Allied shipping . In particular , it was ineffective at protecting English Channel convoys , which were forced to abandon operations for a few months , starting in July 1940 . RAF Fighter Command was given the task , as it enjoyed the majority of RAF resources at the time . The strategic air attack and defence predominated in the RAF , despite the warning signs of 1914 to 1918 , that U - Boats were going to become a main opponent again , and aircraft were a suitable counter to their operations . Coastal Command became the " Cinderella service " until 1943 . The situation would not improve until 1942 . In the meantime , however , Coastal Command did operate with effect alongside RAF Bomber Command in disrupting enemy shipping during the Battle of Britain in 1940 . Coastal Command attacked shipping and mined waters around invasion ports . The German amphibious invasion of Britain in 1940 , Operation Sea Lion , was eventually cancelled owing to the German defeat in the Battle of Britain . During the first three years of the Second World War , Coastal Command and the Admiralty fought a continuous battle with the RAF and Air Ministry over the primacy of trade defence in relation to the bomber effort against mainland Germany , a strategic tussle which conceivably could have cost the Western Alliance the Battle of the Atlantic . The Air Staff and Bomber Command enjoyed the backing of Churchill and the maritime air effort struggled to receive the recognition it needed . On the outbreak of war , the order of battle listed just 298 aircraft , of which only 171 were operational . Owing to the starvation of resources , even as late as March 1943 the Atlantic supply lines were being threatened . This situation arose as a direct result of the lack of very long - range aircraft . Despite the enormous losses of the disastrous 1940 – 1942 period , known to the Germans as the " First " and " Second Happy Time " , the Air Ministry refused to invest in trade defence . Further delays in resource procurement might have led to German success , which could have defeated Britain and forced it out of the war , or at least caused a postponement of Operation Torch , the American - led landing in northwest Africa and Operation Overlord , the landing in France in 1942 and 1944 . Other research indicates that losses unquestionably affected the build - up for Operation Neptune , the actual landing phase of the invasion of Europe . Mid and later war . Eventually the Command was given the investment it needed . Radar and long - range aircraft enabled the Command to hunt down and destroy U - boats with growing efficiency . German submarines had been sinking a large number of Allied ships in the Atlantic Gap , which was a stretch of water in the central Atlantic beyond the range of most Allied aircraft . The covering of the gap by long - range aircraft equipped with radar helped reduce the effectiveness of U - boats . In May 1943 the campaign reached a peak , when a large number of U - boats were sunk with little loss to Allied shipping . During this time Coastal Command gained the initiative . It was known by the Germans as Black May . Thereafter the suppression of German submarines was made not only in the Atlantic , but also in their transit routes through the Bay of Biscay in 1942 , 1943 and 1944 . In June 1944 the Normandy landings and subsequent Operation Overlord liberated France and cost the Germans their air and submarine bases , won in 1940 . The U - boats were thus forced to relocate to Norway and Germany in August , restoring the many of the difficulties faced by the " Kriegsmarine " in 1939 and early 1940 . The entire strategic position , which had been the foundation of the U - Boat war since June 1940 had been undermined . In the last three years of the war , Coastal Command sank more U - boats than any other service and continued to hold the technological advantage from 1943 onwards . A brief threat , in the shape of the German Type XXI submarine emerged , but was too late to alter the course of events . It was not until midnight on the 4 June 1945 that official wartime operations ceased . The last mission was flown by Wing Commander J . Barret DFC , GOC No . 201 Squadron RAF . By that time over 2 , 000 decorations had been awarded . These included four Victoria Crosses , 17 George Medal s , and 82 Distinguished Service Order s . Cold War . Beginnings . The capitulation of Germany in May 1945 was followed by a rapid rundown of Coastal Command with the immediate disbandment of combat units and the transfer of aircraft to the RAF Transport Command . Commonwealth personnel were also sent back home and the powerful Bristol Beaufighter and de Havilland Mosquito wings were decimated . The Command still maintained strong Air - sea - rescue and reconnaissance forces but its ASW was lopsided . With a few exceptions , only a handful of Squadrons with ASW aircraft remained by January 1946 . While the command retained a minimum peacetime force and the Air Ministry had every intention of maintaining it as such , the fleet was further reduced and suffered from procurement problems . The Short Shetland and Short Seaford were rejected as replacements for the B - 24 Liberator . A maritime version of the promising Avro Lincoln had yet to be ordered by the time the lend lease program ended in August 1945 . The Short Sunderland was forced to continue as the main operational type until the end of 1946 . Most of the aircraft that operated in the command were the Second World War types ; the Spitfire , Lancaster , Mosquito and Beaufighter . The command was kept busy in the late 1940s . Units were sent to the Middle East and Palestine as part of an air policing policy , in cooperation with the Israeli Air Force and Egyptian Air Force to prevent conflict between the two countries owing to the formation of the state of Israel in 1948 . While there , they undertook a major operation , Operation Bobcat , to prevent floods of illegal Jewish immigrants coming into Israel . In May 1948 the variety of aircraft was reduced despite increasing demand for operations . In May Palestinian terrorists and their supporters began attacking British military installations throughout the region . In the largest British post - war action , Operation Dawn ( 13 to 14 May 1948 ) was launched with the support of Coastal Command . On 28 June 1948 Coastal Command was also involved in the Berlin Airlift . The Soviet Union attempted to cut off all aid to the city which was jointly occupied by the four major powers ; the Soviets in the east , and the Americans , French and British in the west . The joint American - British operation continued for almost a year . Coastal Command aircraft were involved as flying boats were the only aircraft with internal anti - corrosion treatment allowing bulk salt to be transported . The Command ' s operations grew in intensity . By 13 July , daily sorties had risen to 16 . By October it was 214 sorties ( other RAF Commands were also flying in supplies ) . The flying boats made their flight in using the Elbe river , but these operations came to a close on 14 December 1948 , when the hazard from uncharted sandbanks and wreckage , which , in some cases had been deliberately placed there by the Soviets to prevent the Western Allies from supplying the city , made operations impractical . Over 1 , 000 sorties had been made , and 4 , 500 tons of supplies were flown in and 1 , 113 people , mainly children , evacuated . Soviet threat . NATO ( North Atlantic Treaty Organisation ) began preparations for a military defence of Western Europe by incorporating most West European nations into a defence pact against Soviet aggression in April 1951 . This led to the militarisation of West Germany in 1955 and was met with the militarisation of East Germany soon after , and its merger into the Warsaw Pact alliance with the Soviet Union . The purpose of Coastal Command was to help bolster the defence and guard against a potential Soviet naval threat in Atlantic and European waters . For Coastal Command the main concern was the Atlantic . On 1 March 1950 it had lost the photo reconnaissance units to RAF Bomber Command . The transfer was not complete when North Korea invaded South Korea beginning the Korean War . The Handley Page Hastings was hastily modified and ready for operations but were not sent , owing to the need for ASW aircraft in the Eastern Atlantic . The Avro Shackleton was the main operational aircraft 1950s , replacing the wartime Liberator GRs , along with the Neptune MR . 1s . At the end of August 1951 , No . 201 Squadron RAF became the first unit to complete training on the type . In mid - 1953 , Coastal Commands order of Battle consisted of eight Shackleton Squadrons ; one at Gibraltar , four covering the South West Approaches in the Atlantic , and three more covering the North Western Approaches . This force numbered 64 aircraft . A further four Sunderland Squadrons numbering 20 aircraft were split between the North and South West Approaches . The Neptune Squadrons , numbering 32 aircraft in four Squadrons , covered the North East and Eastern Approaches . The Helicopter also joined Coastal Command . Bristol Sycamore s entered service in 1953 and 16 aircraft were dispersed in Britain for ASW . In March , the Avro Lancaster was finally phased out of Coastal Command service . The Command was too expensive to maintain and cost cuts were made during the 1950s which caused a reduction in strength . By mid - 1957 , the Command had been cut to 82 aircraft . By mid - 1958 it had shrunk to just 67 . The Shackletons dominated the core of this force numbering 54 aircraft . The Neptune was cut from the service altogether , beginning on 31 August 1956 . There was little operational action for the Command at this point . It airlifted British Army forces into Egypt during the Suez Crisis which was its major action during this period . The lack of funds and any active conventional military role saw the Command struggle to keep its frontline strength high . There was a brief alert in October 1962 , during the Cuban Missile Crisis , when all six Squadrons it then possessed were put on high alert , but nothing came of the crisis . In the early 1960s the Soviet Navy and Communist Block ' s fishing fleets began operating around the British Isles in increasing numbers . The British public began taking an interest in their operations as civilian fisherman began complaining about their presence . Operation Chacewater began , in which Coastal Command began monitoring their movements , in particular other vessels that loitered in areas covering the arrival and departure routes for Royal Navy nuclear submarine forces . Soon after , counter operations such as Operation Adjutant were carried out , which was aimed at searching for Soviet submarines . The main threat from the Soviets in the Atlantic came from the Soviet Northern Fleet and in early 1965 most of the Command ' s units were concentrated in No . 18 Group RAF , based in Scotland to monitor their activities . No recorded confrontation took place between Coastal Command and Soviet naval forces during this time . In 1969 the special - purpose Hawker - Siddeley Nimrod , based on the de Havilland Comet airliner , was introduced into RAF service and Coastal Command duties were passed on to general squadrons . The Nimrod was a replacement for the Shackleton and it began to do so on 2 October 1969 . However , less than eight weeks later , Coastal Command was disbanded and ceased to exist on 27 November 1969 , when it was subsumed into RAF Strike Command . Commanders in Chief . The following officers commanded the service : Depiction in film . The work of Coastal Command was immortalised in a 1942 wartime propaganda documentary named " Coastal Command " with a score by Ralph Vaughan Williams . | -
