RAF Coastal Command

RAF Coastal Command was a formation within the Royal Air Force (RAF). It was founded in 1936, when the RAF was restructured into Fighter, Bomber and Coastal Commands and played an important role during the Second World War. Maritime Aviation had been neglected in the inter-war period, due to disagreements between the Royal Navy (RN) and RAF over the ownership, roles and investment in maritime air power.[5]

The Admiralty's main concern until 1937 was the return of the Fleet Air Arm to the Royal Navy while the RAF prioritised the development of a bombing force to provide a deterrent. Coastal Command was referred to as the 'Cinderella Service' by A V Alexander, the First Lord of the Admiralty in November 1940.[6]

Soon after RAF Coastal Area was elevated to Coastal Command, its headquarters moved from Lee-on-Solent to Northwood in northwest London.

During the Second World War, Coastal Command's most important contribution was the protection of Allied convoys from attacks by the German Kriegsmarine's U-boats.[5] It also protected Allied shipping from aerial attacks by the Luftwaffe. The main operations of Coastal Command were defensive, defending supply lines in the Battle of the Atlantic, as well as the Mediterranean, Middle East, and African theatres. It operated from bases in the United Kingdom, Iceland, Gibraltar, the Soviet Union, West Africa and North Africa.[7] It also had an offensive capacity. In the North Sea, Arctic, Mediterranean, and Baltic, strike wings attacked German shipping carrying war materials from Italy to North Africa and from Scandinavia to Germany.

By 1943 Coastal Command finally received sufficient Very Long Range [VLR] aircraft it needed and its operations proved decisive in the victory over the U-boats. These aircraft were Consolidated B-24 Liberators and, from early 1943, these, and other Coastal Command aircraft, were fitted with Mark III ASV [air-to-surface vessel] centimetric radar, the latest depth charges, including homing torpedoes, officially classed as Mark 24 mines [nicknamed 'Wandering Annie' or 'Wandering Willie'] and even rockets. The Command saw action from the first day of hostilities until the last day of the Second World War. It completed one million flying hours,[8] 240,000 operations and destroyed 212 U-boats.[9] Coastal Command's casualties amounted to 2,060 aircraft to all causes. From 1940 to 1945 Coastal Command sank 366 German transport vessels and damaged 134. The total tonnage sunk was 512,330 tons[10] and another 513,454 tons damaged.[9] 10,663 persons were rescued by the Command, comprising 5,721 Allied crew members, 277 enemy personnel, and 4,665 non-aircrews.[11] 5,866 Coastal Command personnel were killed in action.

During the Cold War, Coastal Command concentrated on anti-submarine duties. The perceived main threat was vessels of the Soviet Navy and other fleets of the Warsaw Pact. In 1969, Coastal Command was subsumed into the newly formed Strike Command, which had also absorbed the former Bomber, Fighter and Signals Commands and later also absorbed Air Support Command, the former Transport Command.

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 re-arm 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 Commands and Coastal Area was renamed Coastal Command. Its headquarters was located at Lee-on-Solent. Air Marshal Sir 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.[12]

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 up more than 12 per cent 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,[13] 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 not specialised ASW aircraft, and the Air Ministry was thoroughly uninterested in any aircraft which fell outside the bomber function.[14][15]

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 co-operation 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 misplaced faith in the imperfect ASDIC invention which was never intended to detect surface-running submarines, it appeared the Royal Navy no longer considered U-boats 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 for 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.[16][17]

When the review of the role Coastal Command was to play in war was assessed in 1937, the then AOC Sir 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 apparently assumed aircraft and surface raiders presented the greater threat in British waters, thus following the then Admiralty line that U-boats were no longer a threat.[18] When Admiral Sir Dudley Pound enquired about aerial assets in trade and commerce defence, Chief of the Air Staff Cyril Newall, 1st Baron 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.[19]

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 surface commerce raiders presented the greatest danger, and aircraft could prove decisive only in locating enemy warships.[20] ASW remained in third place, after 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. Secondly, 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.[21]

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.[22] 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.[23][24]

Second World War

Early war

From its formation in 1936, Coastal 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.[25]

The events of April to June 1940 overturned the balance of naval and air power, as the Germans conquered Denmark, Norway, The Netherlands, Belgium and France. The occupation of these countries permitted the Luftwaffe and Kriegsmarine to operate from French ports on the Atlantic coast, hundreds of miles closer to the Atlantic shipping lanes.[26] German medium bombers could also reach British ports on the westernmost and northernmost coasts. The advantage enjoyed by the Germans, allowed them to interdict merchant shipping supplying food and war materials to Britain much more effectively, which had the potential to starve Britain. While merchant shipping was suffering these losses, Coastal Command had proven ineffective at countering German air and sea attacks on shipping.[27] But the command could not protect English Channel convoys, and was forced to abandon operations until July 1940. RAF Fighter Command was given the task, supplying air attack and defence with the enemy. Warning signs after the First World War, that U-boats could become a serious threat once again, meant that aircraft would be the best counter to their operations. This fact not being fully understood, Coastal Command became the 'Cinderella service' until about 1943.[28]

The situation would not improve until 1942.[29] 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 invasion of Britain in 1940, Operation Sea Lion, was eventually cancelled owing to the German defeat in the Battle of Britain.[30]

During the first three years of the Second World War, Coastal Command and the Admiralty fought a 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.[31] On 15 February 1941, Coastal Command was placed under the operational control of the Admiralty. Instrumental in improving the strike rate against submarines was scientific advisor and assistant director of research E. J. Williams, who applied scientific analysis to the logistical problems to great effect. Williams was present at some meetings of the Cabinet Anti-U-boat Committee at 10 Downing Street, under the chairmanship of the Prime Minister.[32][33]

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 Allied landings in French North-West Africa in 1942 and Operation Overlord, the landing in France, in 1944.[34][35] Other research indicates that losses unquestionably affected the build-up for Operation Neptune, the naval phase of the landings in Europe.[36]

Mid and later war

Eventually the Command was given the investment it needed. Radar and long-range aircraft enabled the Command to hunt and destroy U-boats with growing efficiency.[37] 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 very-long-range aircraft equipped with radar helped reduce the effectiveness of U-boats.[38] In May 1943 the campaign reached a peak, when a large number of U-boats were sunk with little loss to Allied shipping; Coastal Command had gained the initiative and it was known by the Germans as Black May. Thereafter the suppression of German submarines was effective in the Atlantic and in their transit routes through the Bay of Biscay in 1942, 1943 and 1944.[39] 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 forced to relocate to Norway and Germany in August, restoring many of the difficulties faced by the Kriegsmarine in 1939 and early 1940.[40][41] The entire strategic position, which had been the foundation of the U-boat war since June 1940 had been undermined.[42]

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. A brief threat, in the shape of the German Type XXI submarine emerged but was too late to alter the course of the war.[43] Technological answers to the Type XXI were available in the form of 3-centimetre radar and magnetic anomaly detectors in aircraft. At midnight 4 June 1945, official wartime operations ceased. The last mission was flown by Wing Commander J. Barret DFC, commanding officer of No. 201 Squadron RAF. By that time over 2,000 decorations had been awarded. These included four Victoria Crosses, of whom only one survived the war, 17 George Medals, and 82 Distinguished Service Orders.[44]
