Strategic bombing is a systematically organized and executed attack from the air which can utilize strategic bombers , long- or medium-range missiles , or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. It is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations , or both. The term terror bombing is used to describe the strategic bombing of civilian targets without military value, in the hope of damaging an enemy's morale.

310-913: A segregated basis. A flight training center was set up at the Tuskegee Institute in Alabama . Despite the handicap—caused by the segregation policy—of not having an experienced training cadre as with other AAF units, the Tuskegee Airmen distinguished themselves in combat with the 332nd Fighter Group . The Tuskegee training program produced 673 black fighter pilots, 253 B-26 Marauder pilots, and 132 navigators. The vast majority of African-American airmen, however, did not fare as well. Mainly draftees , most did not fly or maintain aircraft. Their largely menial duties, indifferent or hostile leadership, and poor morale led to serious dissatisfaction and several violent incidents. Women served more successfully as part of
465-573: A "disturbing failure to follow through on orders". To streamline the AAF in preparation for war, with a goal of centralized planning and decentralized execution of operations, in October 1941 Arnold submitted to the WDGS essentially the same reorganization plan it had rejected a year before, this time crafted by Chief of Air Staff Brig. Gen. Carl A. Spaatz . When this plan was not given any consideration, Arnold reworded
620-469: A 3 mi (4.8 km) radius from point of aim in any case. The United States Army Air Forces adopted a policy of daylight precision bombing for greater accuracy as, for example, during the Schweinfurt raids. That doctrine, based on the erroneous supposition that bombers could adequately defend themselves against air attack, entailed much higher American losses until long-range fighter escorts (e.g.
775-472: A Chief of Air Staff and three deputies. This wartime structure remained essentially unchanged for the remainder of hostilities. In October 1944 Arnold, to begin a process of reorganization for reducing the structure, proposed to eliminate the AC/AS, Training and move his office into OC&R, changing it to Operations, Training and Requirements (OT&R) but the mergers were never effected. On 23 August 1945, after

The Circular No. 59 reorganization directed the AAF to operate under
1085-472: A banker, Lovett had prior experience with the aviation industry that translated into realistic production goals and harmony in integrating the plans of the AAF with those of the Army as a whole. Lovett initially believed that President Roosevelt's demand following the attack on Pearl Harbor for 60,000 airplanes in 1942 and 125,000 in 1943 was grossly ambitious. However, working closely with General Arnold and engaging
1240-557: A blueprint. After war began, Congress enacted the First War Powers Act on 18 December 1941 endowing President Franklin D. Roosevelt with virtual carte blanche to reorganize the executive branch as he found necessary. Under it, on 28 February 1942, Roosevelt issued Executive Order 9082 , based on Marshall's recommendation and the work of McNarney's committee. The EO changed Arnold's title to Commanding General, Army Air Forces effective 9 March 1942, making him co-equal with
1395-419: A change of mood at the War Department, and of dubious legality. By November 1941, on the eve of U.S. entry into the war, the division of authority within the Army as a whole, caused by the activation of Army GHQ a year before, had led to a "battle of memos" between it and the WDGS over administering the AAF, prompting Marshall to state that he had "the poorest command post in the Army" when defense commands showed
1550-563: A combined-arms attack which would be developed to a significant degree by Germany , and which contributed much to the success of the Wehrmacht during the first four years (1939–42) of World War II. The Luftwaffe became a major element of the German blitzkrieg . Some leading theorists of strategic air warfare , namely strategic bombing during this period were the Italian Giulio Douhet ,
1705-453: A complex division of administrative control performed by a policy staff, an operating staff, and the support commands (formerly "field activities" of the OCAC). The former field activities operated under a "bureau" structure, with both policy and operating functions vested in staff-type officers who often exercised command and policy authority without responsibility for results, a system held over from

The leases were negotiated for the AAF by the Corps of Engineers, often to the economic detriment of hotel owners in rental rates, wear and tear clauses, and short-notice to terminate leases. In December 1943,

Since 1939 the overall level of experience among the combat groups had fallen to such an extent that when the demand for replacements in combat was factored in, the entire operational training system
2170-435: A future war as exemplified by Stanley Baldwin 's 1932 comment that the bomber will always get through . One of the aims of war is to demoralize the enemy; facing continual death and destruction may make the prospect of peace or surrender preferable. The proponents of strategic bombing between the world wars, such as General Douhet, expected that direct attacks upon an enemy country's cities by strategic bombers would lead to
2325-694: A general autonomy within the War Department (similar to that of the Marine Corps within the Department of the Navy ) until the end of the war, while its commanders would cease lobbying for independence. Marshall, a strong proponent of airpower, understood that the Air Force would likely achieve its independence following the war. Soon after the Japanese attack on Pearl Harbor on 7 December 1941, in recognition of importance of

In high enough concentration, it was capable of producing a firestorm . The high explosives were often delay-action bombs intended to kill or intimidate those fighting the fires caused by incendiaries. At first this required multiple aircraft, often returning to
2635-698: A major reorganization and consolidation on 29 March 1943. The four main directorates and seventeen subordinate directorates (the "operating staff") were abolished as an unnecessary level of authority, and execution of policies was removed from the staffs to be assigned solely to field organizations along functional lines. The policy functions of the directorates were reorganized and consolidated into offices regrouped along conventional military lines under six assistant chiefs of air staff (AC/AS): Personnel; Intelligence; Operations, Commitments, and Requirements (OC&R); Materiel, Maintenance, and Distribution (MM&D); Plans; and Training. Command of Headquarters AAF resided in
2790-467: A military strategy proved to be an effective and efficient way for the British to police their Middle East protectorates in the 1920s. Fewer men were required as compared to ground forces. Pre-war planners, on the whole, vastly overestimated the damage bombers could do, and underestimated the resilience of civilian populations. Jingoistic national pride played a major role: for example, at a time when Germany
2945-555: A multiplicity of branches and organizations, reduced the WDGS greatly in size, and proportionally increased the representation of the air forces members on it to 50%. In addition to dissolving both Army General Headquarters and the chiefs of the combat arms , and assigning their training functions to the Army Ground Forces, War Department Circular 59 reorganized the Army Air Forces, disbanding both Air Force Combat Command and
3100-563: A perception of resistance and even obstruction then by the bureaucracy in the War Department General Staff (WDGS), much of which was attributable to lack of funds, the Air Corps later made great strides in the 1930s, both organizationally and in doctrine. A strategy stressing precision bombing of industrial targets by heavily armed, long-range bombers emerged, formulated by the men who would become its leaders. A major step toward
3255-464: A proposal for creation of an air staff, unification of the air arm under one commander, and equality with the ground and supply forces. Arnold's proposal was immediately opposed by the General Staff in all respects, rehashing its traditional doctrinal argument that, in the event of war, the Air Corps would have no mission independent of support of the ground forces. Marshall implemented a compromise that

The British also stepped up their strategic bombing campaign. In late 1915, the order was given for attacks on German industrial targets, and the 41st Wing was formed from units of the RNAS and Royal Flying Corps . The RNAS took to
3565-579: A rapid collapse of civilian morale so that political pressure to sue for peace would lead to a rapid conclusion. When such attacks were tried in the 1930s—in the Spanish Civil War and the Second Sino-Japanese War —they were ineffective. Commentators observed the failures and some air forces, such as the Luftwaffe , concentrated their efforts upon direct support of the troops. Terror bombing
3720-497: A result, bomb loads were regularly dropped "blind" using dead-reckoning methods little different from those used by the RAF night bombers. In addition, only the leading bomber in a formation actually utilized the Norden sight, the rest of the formation dropping their bombs only when they saw the lead aircraft's bombload falling away. Since even a very tight bomber formation could cover a vast area,
3875-574: A separate air force came in March 1935, when the command of all combat air units within the Continental United States (CONUS) was centralized under a single organization called the "General Headquarters Air Force" . Since 1920, control of aviation units had resided with commanders of the corps areas (a peacetime ground forces administrative echelon), following the model established by commanding General John J. Pershing during World War I. In 1924,
4030-473: A standard of combat proficiency had barely surpassed the total originally authorized by the first expansion program in 1940. The extant training establishment, in essence a "self-training" system, was inadequate in assets, organization, and pedagogy to train units wholesale. Individual training of freshly minted pilots occupied an inordinate amount of the available time to the detriment of unit proficiency. The ever-increasing numbers of new groups being formed had

The military press censor at SHAEF made a mistake and allowed the Cowan cable to go out starting with "Allied air bosses have made the long awaited decision to adopt deliberate terror bombing of great German population centers as a ruthless expedient to hasten Hitler's doom." There were follow-up newspaper editorials on the issue and a longtime opponent of strategic bombing, Richard Stokes MP , asked questions in

This headquarters was referred to as "XV Fighter Command (Provisional)". Eight air divisions served as an additional layer of command and control for the vast organization, capable of acting independently if the need arose. Inclusive within

They know that within 45 minutes a full-sized village can be practically wiped out and a third of its inhabitants killed or injured". On an official level, RAF directives stressed: In these attacks, endeavour should be made to spare

Use of the term to refer to aerial attacks implies the attacks are criminal according to the law of war , or if within the laws of war are nevertheless a moral crime.

The operation of the stateside depots was done largely by more than 300,000 civilian maintenance employees, many of them women, freeing a like number of Air Forces mechanics for overseas duty. In all facets of the service, more than 420,000 civilian personnel were employed by

In addition, the invasion produced a new Lend lease partner in Russia, creating even greater demands on an already struggling American aircraft production. An offensive strategy required several types of urgent and sustained effort. In addition to the development and manufacture of aircraft in massive numbers,

However, the Japanese military in most places advanced quickly enough that a strategic bombing campaign was unnecessary, and the Japanese aircraft industry was incapable of producing truly strategic bombers in any event. In those places where it

Conditions in the European theatre made it very difficult to achieve the accuracy achieved using the exceptional and top-secret Norden optical bombsight in the clear skies over the desert bombing ranges of Nevada and California.

Almost 1.4 million men received technical training as aircraft mechanics, electronics specialists, and other technicians. Non-aircraft related support services were provided by airmen trained by

During the Spanish Civil War , the bombing of Guernica by German aviators including the Condor Legion , under Nationalist command, resulted in its near destruction.

6510-597: The AAF created a reserve pool that held qualified pilot candidates until they could be called to active duty, rather than losing them in the draft. By 1944, this pool became surplus, and 24,000 were sent to the Army Ground Forces for retraining as infantry , and 6,000 to the Army Service Forces . Pilot standards were changed to reduce the minimum age from 20 to 18, and eliminated the educational requirement of at least two years of college. Two fighter pilot beneficiaries of this change went on to become brigadier generals in

At the end of the war, the AAF was using almost 20 million acres of land, an area as large as Massachusetts , Connecticut , Vermont , and New Hampshire combined. By the end of World War II, the USAAF had created 16 numbered air forces ( First through Fifteenth and Twentieth ) distributed worldwide to prosecute

The huge increases in aircraft inventory resulted in a similar increase in personnel, expanding sixteen-fold in less than three years following its formation, and changed the personnel policies under which the Air Service and Air Corps had operated since the National Defense Act of 1920. No longer could pilots represent 90% of commissioned officers. The need for large numbers of specialists in administration and technical services resulted in
7130-525: The Air Corps expanded from 15 to 30 groups by the end of the year. On 7 December 1941 the number of activated combat groups had reached 67, with 49 still within the Continental United States. Of the CONUS groups (the "strategic reserve"), 21 were engaged in operational training or still being organized and were unsuitable for deployment. Of the 67 combat groups, 26 were classified as bombardment: 13 Heavy Bomb groups ( B-17 Flying Fortress and B-24 Liberator ), and
7285-545: The Air Corps found entirely inadequate, naming Arnold as acting "Deputy Chief of Staff for Air" but rejecting all organizational points of his proposal. GHQ Air Force instead was assigned to the control of Army General Headquarters, although the latter was a training and not an operational component, when it was activated in November 1940. A division of the GHQ Air Force into four geographical air defense districts on 19 October 1940
7440-480: The Air Corps in October 1940 saw fifteen new general officer billets created. By the end of World War II, 320 generals were authorized for service within the wartime AAF. The Air Corps operated 156 installations at the beginning of 1941. An airbase expansion program had been underway since 1939, attempting to keep pace with the increase in personnel, units, and aircraft, using existing municipal and private facilities where possible, but it had been mismanaged, first by

Airpower advocates achieved a centralized control of air units under an air commander, while the WDGS divided authority within the air arm and assured a continuing policy of support of ground operations as its primary role. GHQ Air Force organized combat groups administratively into a strike force of three wings deployed to the Atlantic , Pacific, and Gulf coasts but

American fighter aircraft were inferior to the British Spitfire and Hurricane , and German Messerschmitt Bf 110 and 109 . Ralph Ingersoll wrote in late 1940 after visiting Britain that the "best American fighter planes already delivered to the British are used by them either as advanced trainers—or for fighting equally obsolete Italian planes in

The concept of an "operating staff", or directorates, was modeled on the RAF system that had been much admired by the observer groups sent over in 1941, and resulted from a desire to place experts in various aspects of military aviation into key positions of implementation. However functions often overlapped, communication and coordination between the divisions failed or was ignored, policy prerogatives were usurped by

The peak size of the AAF during World War II was over 2.4 million men and women in service and nearly 80,000 aircraft by 1944, and 783 domestic bases in December 1943. By " V-E Day ", the Army Air Forces had 1.25 million men stationed overseas and operated from more than 1,600 airfields worldwide. The Army Air Forces

While officially the air arm was the Army Air Forces , the term Air Corps persisted colloquially among the public as well as veteran airmen; in addition, the singular Air Force often crept into popular and even official use, reflected by the designation Air Force Combat Command in 1941–42. This misnomer

In all, four people were killed and sixteen injured, and monetary damage was estimated at £7,740 (about US$ 36,000 at the time). German airships also bombed on other fronts, for example in January 1915 on Liepāja in Latvia. In 1915 there were 19 more raids, in which 37 tons of bombs were dropped, killing 181 people and injuring 455. Raids continued in 1916. London

A much greater impact was the diversion of twelve aircraft squadrons, many guns, and over 10,000 men to air defenses. The raids generated a wave of hysteria, partially caused by media. This revealed

After the Butt Report (released in September 1941) proved the inadequacy of RAF Bomber Command training methods and equipment, the RAF adopted an area-attack strategy, by which it hoped to impede Germany's war production, her powers of resistance (by destroying resources and forcing Germany to divert resources from her front lines to defend her air space), and her morale. The RAF dramatically improved its navigation so that on average its bombs hit closer to target. Accuracy never exceeded

Not only would such attacks weaken the enemy by destroying important military infrastructure, they would also break the morale of the civilian population, forcing their government to capitulate. Although area bombing theorists acknowledged that measures could be taken to defend against bombers—using fighter planes and anti-aircraft artillery —the maxim of
11470-492: The USAAF's strategic bombing campaign in Europe, with its avowed (if unachievable) objective of precision bombing of strategic targets, the bombing of Japanese cities involved the deliberate targeting of residential zones from the outset. Bomb loads included very high proportions of incendiaries, with the intention of igniting the highly combustible wooden houses common in Japanese cities and thereby generating firestorms. The final development of strategic bombing in World War II
11625-674: The United States . The AAF was a component of the United States Army , which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces , the United States Army Services of Supply (which in 1943 became the Army Service Forces ), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff . The AAF administered all parts of military aviation formerly distributed among
11780-518: The United States, where excerpts from his book The Command of the Air (1921) were published. These visions of cities laid waste by bombing also gripped the popular imagination and found expression in novels such as Douhet's The War of 19-- (1930) and H. G. Wells 's The Shape of Things to Come (1933) (filmed by Alexander Korda as Things to Come (1936)). Douhet's proposals were hugely influential among air force enthusiasts, arguing as they did that
11935-541: The WAACs and WACs as AAF personnel, more than 1,000 as Women Airforce Service Pilots (WASPs), and 6,500 as nurses in the Army Air Forces, including 500 flight nurses. 7,601 "Air WACs" served overseas in April 1945, and women performed in more than 200 job categories. The Air Corps Act of July 1926 increased the number of general officers authorized in the Army's air arm from two to four. The activation of GHQAF in March 1935 doubled that number to eight and pre-war expansion of
12090-634: The Yemeni side, were 65 killed or wounded (one RAF pilot was killed and one airman wounded). Between the wars the RAF conducted 26 separate air operations within the Aden Protectorate. The majority were conducted in response to persistent banditry or to restore the Government's authority. Excluding operations against Yemeni forces—which had effectively ceased by 1934—a total of twelve deaths were attributed to air attacks conducted between 1919 and 1939. Bombing as
12245-631: The acceptance of the provisions of the Joint Declaration of the Powers. Nuclear weapons defined strategic bombing during the Cold War . The age of the massive strategic bombing campaign had come to an end. It was replaced by more devastating attacks using improved targeting and weapons technology. Strategic bombing by the Great Powers also became politically indefensible. The political fallout resulting from
12400-430: The air forces and to avoid binding legislation from Congress, the War Department revised the army regulation governing the organization of Army aviation, AR 95–5. Arnold assumed the title of Chief of the Army Air Forces , creating an echelon of command over all military aviation components for the first time and ending the dual status of the Air Corps and GHQ Air Force, which was renamed Air Force Combat Command (AFCC) in
12555-473: The air forces, commands and divisions were administrative headquarters called wings to control groups (operational units; see section below). As the number of groups increased, the number of wings needed to control them multiplied, with 91 ultimately activated, 69 of which were still active at the end of the war. As part of the Air Service and Air Corps, wings had been composite organizations, that is, composed of groups with different types of missions. Most of
12710-473: The air raids with a series of night infiltration bombings of ADD airfields near Leningrad . Strategic bombing in Europe never reached the decisive completeness the American campaign against Japan achieved, helped in part by the fragility of Japanese housing , which was particularly vulnerable to firebombing through the use of incendiary devices . The destruction of German infrastructure became apparent, but
12865-481: The annual addition to the force of 30,000 new pilots and 100,000 technical personnel. The accelerated expansion programs resulted in a force of 156 airfields and 152,125 personnel at the time of the creation of the Army Air Forces. In its expansion during World War II, the AAF became the world's most powerful air force. From the Air Corps of 1939, with 20,000 men and 2,400 planes, to the nearly autonomous AAF of 1944, with almost 2.4 million personnel and 80,000 aircraft,
13020-521: The bombing air arm was the most important, powerful, and invulnerable part of any military. He envisaged future wars as lasting a matter of a few weeks. While each opposing Army and Navy fought an inglorious holding campaign, the respective Air Forces would dismantle their enemies' country, and if one side did not rapidly surrender, both would be so weak after the first few days that the war would effectively cease. Fighter aircraft would be relegated to spotting patrols but would be essentially powerless to resist
13175-507: The bombing of railways, trains, canals, and roads more harmful to production than attacks on factories themselves, Sir Roy Fedden (in his report on a postwar British scientific intelligence mission) calling it "fatal" and saying it reduced aero-engine production by two thirds (from a maximum output of 5,000 to 7,000 a month). Strategic bombing was a way of taking the war into Europe while Allied ground forces were unable to do so. Between them, Allied air forces claimed to be able to bomb "around
13330-463: The capacity of the American automotive industry brought about an effort that produced almost 100,000 aircraft in 1944. The AAF reached its wartime inventory peak of nearly 80,000 aircraft in July 1944, 41% of them first line combat aircraft, before trimming back to 73,000 at the end of the year following a large reduction in the number of trainers needed. The logistical demands of this armada were met by
13485-430: The capitulation of Japan, realignment took place with the complete elimination of OC&R. The now five assistant chiefs of air staff were designated AC/AS-1 through -5 corresponding to Personnel, Intelligence, Operations and Training, Materiel and Supply, and Plans. Most personnel of the Army Air Forces were drawn from the Air Corps. In May 1945, 88 per cent of officers serving in the Army Air Forces were commissioned in
13640-503: The civilian population , thought to be demoralizing to the enemy, seemed to have the opposite effect. E. B. Strauss surmised, "Observers state that one of the most remarkable effects of the bombing of open towns in Government Spain had been the welding together into a formidable fighting force of groups of political factions who were previously at each other's throats...", a sentiment with which Hitler 's Luftwaffe , supporting
13795-478: The clock". In fact, few targets were ever hit by British and American forces the same day, the strategic isolation of Normandy on D-Day and the bombing of Dresden in February 1945 being exceptions rather than the rule. There were generally no coordinated plans for the around-the-clock bombing of any target. In some cases, single missions have been considered to constitute strategic bombing. The bombing of Peenemünde
13950-511: The commanders of GHQ Air Force and the Air Corps, Major Generals Frank M. Andrews and Oscar Westover respectively, clashed philosophically over the direction in which the air arm was moving, exacerbating the difficulties. The expected activation of Army General Headquarters prompted Army Chief of Staff George C. Marshall to request a reorganization study from Chief of the Air Corps Maj. Gen. Henry H. Arnold resulting on 5 October 1940 in
14105-557: The commanding generals of the new Army Ground Forces and Services of Supply , the other two components of the Army of the United States . The War Department issued Circular No. 59 on 2 March that carried out the executive order, intended (as with the creation of the Air Service in World War I) as a wartime expedient to expire six months after the end of the war. The three components replaced
14260-683: The conduct of all aspects of the air war in every part of the world, determining air policy and issuing orders without transmitting them through the Army Chief of Staff. This "contrast between theory and fact is...fundamental to an understanding of the AAF." The roots of the Army Air Forces arose in the formulation of theories of strategic bombing at the Air Corps Tactical School that gave new impetus to arguments for an independent air force, beginning with those espoused by Brig. Gen. Billy Mitchell that led to his later court-martial . Despite
14415-596: The creation of the Air Service Command on 17 October 1941 to provide service units and maintain 250 depots in the United States; the elevation of the Materiel Division to full command status on 9 March 1942 to develop and procure aircraft, equipment, and parts; and the merger of these commands into the Air Technical Service Command on 31 August 1944. In addition to carrying personnel and cargo,
14570-452: The day of detachment of the cadre, the first half of the process bringing the new unit up to strength, the second half devoted to flying training, with the final six weeks concentrating on fighting as a unit. Strategic bombing One of the strategies of war is to demoralize the enemy so that peace or surrender becomes preferable to continuing the conflict. Strategic bombing has been used to this end. The phrase "terror bombing" entered
14725-410: The detachment radius) of communications, their indifference to obstacles, and the unlikelihood of casualties to air personnel combine to encourage their use offensively more often than the occasion warrants. In British strikes over Yemen in over a six-month period, sixty tons of bombs were dropped in over 1,200 cumulative flying hours. By August 1928, total losses in ground fighting and air attack, on
14880-469: The direct control of Headquarters Army Air Forces. At the end of 1942 and again in the spring of 1943 the AAF listed nine support commands before it began a process of consolidation that streamlined the number to five at the end of the war. These commands were: "In 1943 the AAF met a new personnel problem, to which it applied an original solution: to interview, rehabilitate, and reassign men returning from overseas. [To do this], an AAF Redistribution Center
15035-620: The directorates, and they became overburdened with detail, all contributing to the diversion of the directorates from their original purpose. The system of directorates in particular handicapped the developing operational training program (see Combat units below), preventing establishment of an OTU command and having a tendency to micromanage because of the lack of centralized control. Four main directorates—Military Requirements, Technical Services, Personnel, and Management Control—were created, each with multiple sub-directorates, and eventually more than thirty offices were authorized to issue orders in
15190-447: The dormant struggle for an independent United States Air Force. Marshall had come to the view that the air forces needed a "simpler system" and a unified command. Working with Arnold and Robert A. Lovett , recently appointed to the long-vacant position of Assistant Secretary of War for Air, he reached a consensus that quasi-autonomy for the air forces was preferable to immediate separation. On 20 June 1941, to grant additional autonomy to
15345-552: The end of World War II, the Army Air Forces had become virtually an independent service. By regulation and executive order, it was a subordinate agency of the United States Department of War (as were the Army Ground Forces and the Army Service Forces) tasked only with organizing, training, and equipping combat units and limited in responsibility to the continental United States. In reality, Headquarters AAF controlled
15500-542: The establishment of an Officer Candidate School in Miami Beach, Florida , and the direct commissioning of thousands of professionals. Even so, 193,000 new pilots entered the AAF during World War II, while 124,000 other candidates failed at some point during training or were killed in accidents. The requirements for new pilots resulted in a massive expansion of the Aviation Cadet program, which had so many volunteers that
15655-661: The famous iconic " Why We Fight " series, as an animated map graphic of equal prominence to that of the Army and Navy. The Air Corps at the direction of President Roosevelt began a rapid expansion from the spring of 1939 forward, partly from the Civilian Pilot Training Program created at the end of 1938, with the goal of providing an adequate air force for defense of the Western Hemisphere. An initial "25-group program", announced in April 1939, called for 50,000 men. However, when war broke out in September 1939
15810-436: The first independent strategic bombing force, was created in April 1918. By the end of the war, the force had aircraft that could reach Berlin , but these were never used. Following the war, the concept of strategic bombing developed. Calculations of the number of dead to the weight of bombs would have a profound effect on the attitudes of the British authorities and population in the interwar years. As bombers became larger, it
15965-448: The following two decades fighting for survival in an environment of severe government spending constraints. In Italy, the airpower prophet General Giulio Douhet asserted the basic principle of strategic bombing was the offensive, and there was no defense against carpet bombing and poison gas attacks. The seeds of Douhet's apocalyptic predictions found fertile soil in France, Germany, and
16120-410: The force array. In the first half of 1942 the Army Air Forces expanded rapidly as the necessity of a much larger air force than planned was immediately realized. Authorization for the total number of combat groups required to fight the war nearly doubled in February to 115. In July it jumped to 224, and a month later to 273. When the U.S. entered the war, however, the number of groups actually trained to
16275-406: The force of four aircraft inflicted minor damage on the sheds. The raid was repeated a month later with slightly more success. Within a year or so, specialized aircraft and dedicated bomber squadrons were in service on both sides. These were generally used for tactical bombing; the aim was that of directly harming enemy troops, strongpoints, or equipment, usually within a relatively small distance of
16430-463: The front line. Eventually, attention turned to the possibility of causing indirect harm to the enemy by systematically attacking vital rear-area resources. The most well known attacks were those done by Zeppelins over England through the course of the war. The first aerial bombardment of English civilians was on January 19, 1915, when two Zeppelins dropped 24 fifty-kilogram (110-pound) high-explosive bombs and ineffective three-kilogram incendiaries on
16585-637: The ground forces by March 1942. In the spring of 1941, the success in Europe of air operations conducted under centralized control (as exemplified by the British Royal Air Force and the German Wehrmacht 's military air arm, the Luftwaffe ) made clear that the splintering of authority in the American air forces, characterized as " hydra -headed" by one congressman, had caused a disturbing lack of clear channels of command. Less than five months after
16740-454: The mighty bombers. In support of this theory, he argued for targeting of the civilian population as much as any military target, since a nation's morale was as important a resource as its weapons. Paradoxically, he suggested that this would actually reduce total casualties, since "The time would soon come when to put an end to horror and suffering, the people themselves, driven by the instinct of self-preservation, would rise up and demand an end to
16895-544: The name of the commanding general. Among the headquarters directorates were Technical Services, Air Defense, Base Services, Ground-Air Support, Management Control, Military Equipment, Military Requirements , and Procurement & Distribution. A "strong and growing dissatisfaction" with the organization led to an attempt by Lovett in September 1942 to make the system work by bringing the Directorate of Management Control and several traditional offices that had been moved to
17050-402: The new organization. The AAF gained the formal "Air Staff" long opposed by the General Staff, and a single air commander, but still did not have equal status with the Army ground forces, and air units continued to report through two chains of command. The commanding general of AFCC gained control of his stations and court martial authority over his personnel, but under the new field manual FM-5
17205-704: The only answers—a later generation would revisit this, as Mutual Assured Destruction . During the interwar period (1919–1939), the use of aerial bombing was developed as part of British foreign policy in its colonies, with Hugh Trenchard as its leading proponent, Sir Charles Portal , Sir Arthur Harris , and Sidney Bufton . The Trenchard School theories were successfully put into action in Mesopotamia (modern-day Iraq ) where RAF bombers used high-explosive bombs and strafing runs against Arab forces. The techniques of so-called "Air Control" also included target marking and locating, as well as formation flying. Arthur Harris ,
17360-471: The operating staff, including the Air Judge Advocate and Budget Officer, back under the policy staff umbrella. When this adjustment failed to resolve the problems, the system was scrapped and all functions combined into a single restructured air staff. The hierarchical "command" principle, in which a single commander has direct final accountability but delegates authority to staff, was adopted AAF-wide in
17515-921: The operational command was designated by the Roman numeral of its parent numbered air force. For instance, the Eighth Air Force listed the VIII Bomber Command and the VIII Fighter Command as subordinate operational commands. Roman numbered commands within numbered air forces also included "support", "base", and other services commands to support the operational units, such as the VIII Air Force Service and VIII Air Force Composite Commands also part of Eighth Air Force during its history. The Tenth and Fourteenth Air Forces did not field subordinate commands during World War II. Fifteenth Air Force organized
17670-511: The proposal the following month which, in the face of Marshall's dissatisfaction with Army GHQ, the War Plans Division accepted. Just before Pearl Harbor, Marshall recalled an Air Corps officer, Brig. Gen. Joseph T. McNarney , from an observer group in England and appointed him to chair a "War Department Reorganization Committee" within the War Plans Division, using Arnold's and Spaatz's plan as
17825-442: The rejection of Arnold's reorganization proposal, a joint U.S.-British strategic planning agreement ( ABC-1 ) refuted the General Staff's argument that the Air Corps had no wartime mission except to support ground forces. A struggle with the General Staff over control of air defense of the United States had been won by airmen and vested in four command units called "numbered air forces", but the bureaucratic conflict threatened to renew
17980-482: The responsible air forces, but after 9 October 1942, by the Army Air Force School of Applied Tactics (AAFSAT) to standardize curriculum and instruction. New graduates of training schools fleshed out the satellite group and also restored the parent group to its overstrength size. The parent group was responsible for the organization and training of its satellite, normally a process six months in length that began
18135-526: The rest Medium and Light groups ( B-25 Mitchell , B-26 Marauder , and A-20 Havoc ). The balance of the force included 26 Pursuit groups (renamed fighter group in May 1942), 9 Observation (renamed Reconnaissance ) groups, and 6 Transport (renamed Troop Carrier or Combat Cargo ) groups. After the operational deployment of the B-29 Superfortress bomber, Very Heavy Bombardment units were added to
18290-511: The role of the Army Air Forces, Arnold was given a seat on the Joint Chiefs of Staff , the planning staff that served as the focal point of American strategic planning during the war, in order that the United States would have an air representative in staff talks with their British counterparts on the Combined Chiefs . In effect the head of the AAF gained equality with Marshall. While this step
18445-521: The sake of increasing the terror, though under other pretexts, should be reviewed...." Under pressure from the Chiefs of Staff and in response to the views expressed by Chief of the Air Staff Sir Charles Portal , and the head of Bomber Command, Arthur "Bomber" Harris , among others, Churchill withdrew his memo and issued a new one. This was completed on 1 April 1945 and started instead with
18600-448: The scatter of bombs was likely to be considerable. Add to these difficulties the disruptive effects of increasingly accurate anti-aircraft fire and head-on attacks by fighter aircraft and the theoretical accuracy of daylight bombing was often hard to achieve. Accuracy, described as "pinpoint", never exceeded the best British average of about a 3 mi (4.8 km) radius from point of aim in any case. Postwar German engineers considered
18755-601: The strategic bombing in a bigger way than the RFC, who were focused on supporting the infantry actions of the Western Front. At first, the RNAS attacked the German submarines in their moorings and then steelworks further in targeting the origin of the submarines themselves. In early 1918 they operated their "round the clock" bombing raid, with lighter bombers attacking the town of Trier by day and large HP O/400s attacking by night. The Independent Force , an expanded bombing group, and
18910-499: The tactic's potential as a weapon that was of use for propagandists on both sides. The late Zeppelin raids were complemented by the Gotha bomber, which was the first heavier-than-air bomber to be used for strategic bombing. The French army on June 15, 1915, attacked the German town of Karlsruhe , killing 29 civilians and wounding 58. Further raids followed until the Armistice in 1918. In
19065-450: The target in waves. Nowadays, a large bomber or missile can be used to the same effect on a small area (an airfield, for example) by releasing a relatively large number of smaller bombs. Strategic bombing campaigns were conducted in Europe and Asia. The Germans and Japanese made use of mostly twin-engined bombers with a payload generally less than 5,000 pounds (2,300 kg), and never produced larger craft to any great extent. By comparison,
19220-516: The term has pejorative connotations, others have denied that such bombing campaigns and raids are examples of "terror bombing". Defensive measures against air raids include: Strategic bombing was used in World War I, though it was not understood in its present form. The first aerial bombing of a city was on 6 August 1914 when the German Army Zeppelin Z VI bombed, with artillery shells,
19375-404: The times remained " the bomber will always get through ". These theorists for strategic bombing argued that it would be necessary to develop a fleet of strategic bombers during peacetime, both to deter any potential enemy, and also in the case of a war, to be able to deliver devastating attacks on the enemy industries and cities while suffering from relatively few friendly casualties before victory
19530-406: The toll of many innocent lives. Should We continue to fight, it would not only result in an ultimate collapse and obliteration of the Japanese nation but also it would lead to the total extinction of human civilization. Such being the case, how are We to save the millions of Our subjects; or to atone Ourselves before the hallowed spirits of Our Imperial Ancestors? This is the reason why We have ordered
19685-569: The unique ability of a modern air force to win wars by unaided strategic bombing. As the speed and altitude of bombers increased in proportion to fighter aircraft, the prevailing strategic understanding became "the bomber will always get through". Although anti-aircraft guns and fighter aircraft had proved effective in the Great War, it was accepted there was little warring nations could do to prevent massive civilian casualties from strategic bombing . High civilian morale and retaliation in kind were seen as
19840-429: The usual euphemism used when referring to strategic bombing: "It seems to me that the moment has come when the question of the so called 'area-bombing' of German cities should be reviewed from the point of view of our own interests....". Many strategic bombing campaigns and individual raids of aerial warfare have been described as "terror bombing" by commentators and historians since the end of World War II, but because
19995-484: The war, plus a general air force within the continental United States to support the whole and provide air defense. The latter was formally organized as the Continental Air Forces and activated on 15 December 1944, although it did not formally take jurisdiction of its component air forces until the end of the war in Europe. Half of the numbered air forces were created de novo as the service expanded during
20150-615: The war, when Germany invaded Poland on 1 September 1939. A strategic-bombing campaign was launched by the Germans as a precursor to the invasion of the United Kingdom to force the RAF to engage the Luftwaffe and so be destroyed either on the ground or in the air. That tactic failed, and the RAF began bombing German cities on 11 May 1940. After the Battle of Britain , the Germans launched their night time Blitz hoping to break British morale and to have
20305-461: The war-time Army Air Forces. The AAF was willing to experiment with its allotment from the unpopular Women's Army Auxiliary Corps (WAACs) and became an early and determined supporter of full military status for women in the Army ( Women's Army Corps or WACs). WACs serving in the AAF became such an accepted and valuable part of the service they earned the distinction of being commonly (but unofficially) known as "Air WACs". Nearly 40,000 women served in
20460-618: The war. Some grew out of earlier commands as the service expanded in size and hierarchy (for example, the V Air Support Command became the Ninth Air Force in April 1942), and higher echelons such as United States Strategic Air Forces (USSTAF) in Europe and U.S. Strategic Air Forces in the Pacific became necessary to control the whole. Within numbered air forces, operational commands were created to divide administrative control of units by function (eg fighters and bombers). The numbering of
20615-431: The war...". As a result of Douhet's proposals, air forces allocated greater resources to their bomber squadrons than to their fighters, and the 'dashing young pilots' promoted in the propaganda of the time were invariably bomber pilots. Royal Air Force leaders, in particular Air Chief Marshal Hugh Trenchard , believed the key to retaining their independence from the senior services was to lay stress on what they saw as
20770-404: The wings of World War II, however, were composed of groups with like functions (denoted as bombardment , fighter , reconnaissance , training , antisubmarine , troop carrier , and replacement ). The six support commands organized between March 1941 and April 1942 to support and supply the numbered air forces remained on the same chain of command echelon as the numbered air forces, under
20925-449: The women and children as far as possible, and for this purpose, a warning should be given, whenever practicable. It would be wrong even at this stage to think that airpower was simply seen as a tool for rapid retribution. A statement clearly pointed out that the ability of aircraft to inflict punishment could be open to abuse: Their power to cover great distances at high speed, their instant readiness for action, their independence (within
21080-604: Was a remarkable expansion. Robert A. Lovett, the Assistant Secretary of War for Air, together with Arnold, presided over an increase greater than for either the ground Army or the Navy, while at the same time dispatching combat air forces to the battlefronts. The German invasion of the Soviet Union , occurring only two days after the creation of the Army Air Forces, caused an immediate reassessment of U.S. defense strategy and policy. The need for an offensive strategy to defeat
21235-489: Was accidentally bombed in May, and in July the Kaiser allowed directed raids against urban centers. There were 23 airship raids in 1916, in which 125 tons of ordnance were dropped, killing 293 people and injuring 691. Gradually British air defenses improved. In 1917 and 1918, there were only 11 Zeppelin raids against England, and the final raid occurred on August 5, 1918, which resulted in the death of KK Peter Strasser , commander of
21390-433: Was achieved. In the period between the two world wars, military thinkers from several nations advocated strategic bombing as the logical and obvious way to employ aircraft. Domestic political considerations saw to it that the British worked harder on the concept than most. The British Royal Flying Corps and Royal Naval Air Service of the Great War had been merged in 1918 to create a separate air force, which spent much of
21545-536: Was also used on official recruiting posters (see image above) and was important in promoting the idea of an "Air Force" as an independent service. Jimmy Stewart , a Hollywood movie star serving as an AAF pilot, used the terms "Air Corps" and "Air Forces" interchangeably in the narration of the 1942 recruiting short " Winning Your Wings " . The term "Air Force" also appeared prominently in Frank Capra 's 1945 War Department indoctrination film " War Comes to America " , of
21700-569: Was concurrent with the creation of air forces to defend Hawaii and the Panama Canal . The air districts were converted in March 1941 into numbered air forces with a subordinate organization of 54 groups. The likelihood of U.S. participation in World War II prompted the most radical reorganization of the aviation branch in its history, developing a structure that both unified command of all air elements and gave it total autonomy and equality with
21855-457: Was created in June 1941 to provide the air arm greater autonomy in which to expand more efficiently, to provide a structure for the additional command echelons required by a vastly increased force, and to end an increasingly divisive administrative battle within the Army over control of aviation doctrine and organization that had been ongoing since the creation of an aviation section within the U.S. Army Signal Corps in 1914. The AAF succeeded both
22010-468: Was developed between the two world wars. Some leading theorists of strategic air warfare during this period were the Italian Giulio Douhet , the Trenchard school in the United Kingdom, and General Billy Mitchell in the United States. These theorists were highly influential, both on the military justification for an independent air force (such as the Royal Air Force ) and in influencing political thoughts on
22165-484: Was established on 7 August 1943, and given command status on 1 June 1944. as the AAF Personnel Distribution Command. This organization was ordered discontinued, effective 30 June 1946." The primary combat unit of the Army Air Forces for both administrative and tactical purposes was the group , an organization of three or four flying squadrons and attached or organic ground support elements, which
22320-411: Was fully expected that deaths would dramatically increase. The fear of aerial attack on such a scale was one of the fundamental driving forces of the appeasement of Nazi Germany in the 1930s. These early developments of aerial warfare led to two distinct branches in the writings of air warfare theorists: tactical air warfare and strategic air warfare. Tactical air warfare was developed as part of
22475-575: Was in a Reader's Digest article dated June 1941, a finding confirmed by the Oxford English Dictionary . Aerial attacks described as terror bombing are often long range strategic bombing raids, although attacks which result in the deaths of civilians may also be described as such, or if the attacks involve fighters strafing they may be labelled "terror attacks". German propaganda minister Joseph Goebbels and other high-ranking officials of Nazi Germany frequently described attacks by
22630-494: Was never officially recognized by the United States Navy , and was bitterly disputed behind the scenes at every opportunity, it nevertheless succeeded as a pragmatic foundation for the future separation of the Air Force. Under the revision of AR 95–5, the Army Air Forces consisted of three major components: Headquarters AAF, Air Force Combat Command, and the Air Corps. Yet the reforms were incomplete, subject to reversal with
22785-525: Was required, the smaller Japanese bombers (in comparison to British and American types) did not carry a bombload sufficient to inflict the sort of damage regularly occurring at that point in the war in Europe, or later in Japan. The development of the B-29 gave the United States a bomber with sufficient range to reach the Japanese home islands from the safety of American bases in the Pacific or western China. The capture of
22940-464: Was small in comparison to European air forces. Lines of authority were difficult, at best, since GHQ Air Force controlled only operations of its combat units while the Air Corps was still responsible for doctrine, acquisition of aircraft, and training. Corps area commanders continued to exercise control over airfields and administration of personnel, and in the overseas departments, operational control of units as well. Between March 1935 and September 1938,
23095-477: Was still disarmed and France was Britain's only European rival, Trenchard boasted, "the French in a bombing duel would probably squeal before we did". At the time, the expectation was any new war would be brief and very brutal. A British Cabinet planning document in 1938 predicted that, if war with Germany broke out, 35% of British homes would be hit by bombs in the first three weeks. This type of expectation would justify
23250-636: Was such an event, as was the bombing of the Ruhr dams . The Peenemünde mission delayed Nazi Germany's V-2 program enough that it did not become a major factor in the outcome of the war. Soviet Air Forces conducted strategic bombings of Helsinki , the capital of Finland , between 1939 and 1944, with Finland being subjected to a number of bombing campaigns by the USSR in that period. The largest were three raids in February 1944, which have been called The Great Raids Against Helsinki . The Finnish Air Force responded to
23405-404: Was the major land-based aerial warfare service component of the United States Army and de facto aerial warfare service branch of the United States during and immediately after World War II (1941–1947). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force , today one of the six armed forces of
23560-455: Was the rough equivalent of a regiment of the Army Ground Forces . The Army Air Forces fielded a total of 318 combat groups at some point during World War II, with an operational force of 243 combat groups in 1945. The Air Service and its successor the Air Corps had established 15 permanent combat groups between 1919 and 1937. With the buildup of the combat force beginning 1 February 1940,
23715-423: Was the use of nuclear weapons. On August 6 and 9, 1945, the United States exploded nuclear bombs over Hiroshima and Nagasaki, killing 105,000 people and inflicting a psychological shock on the Japanese nation. On August 15, Emperor Hirohito announced the surrender of Japan , stating : Moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to do damage is indeed incalculable, taking
23870-575: Was threatened. To avoid this probable crisis, an Operational Training Unit (OTU) system was adopted as it had been by the RAF. Under the American OTU concept, certain experienced groups were authorized as overstrength "parent" groups. A parent group (OTU unit) provided approximately 20% of its seasoned personnel as cadre to a newly activated, or "satellite", group. Cadres detached to the newly activated satellite group were first provided with special instruction on their training responsibilities, initially by
24025-490: Was to come in the near future. Yet the theory that " the bomber will always get through " started to appear doubtful, as stated by the U.S. Attaché in 1937, "The peacetime theory of the complete invulnerability of the modern type of bombardment airplane no longer holds. The increased speeds of both the bombardment and pursuit plane have worked in favor of the pursuit ... The flying fortress died in Spain." Large scale bombing of
