The Air War Plans Division (AWPD) was an American military organization established to make long-term plans for war. Headed by Harold L. George, the unit was tasked in July 1941 to provide President Franklin D. Roosevelt with "overall production requirements required to defeat our potential enemies."[1] The plans that were made at the AWPD eventually proved significant in the defeat of Nazi Germany.[2]
The AWPD went beyond offering basic production requirements and provided a comprehensive air plan which was designed to defeat the Axis powers.[1] The plan, AWPD-1, was completed in nine days.[2] The plan emphasized using heavy bombers to carry out precision bombing attacks as the primary method of defeating Germany and its allies. A year later, after the United States became directly involved in World War II, AWPD delivered a second plan—AWPD-42—which slightly changed the earlier plan to incorporate lessons learned from eight months of the war. Neither AWPD-1 nor AWPD-42 were approved as combat battle plans or war operations; they were simply accepted as guidelines for the production of materiel[3] and the creation of necessary air squadrons. Finally, in 1943, an operational aerial warfare plan was agreed in meetings between American and British war planners, based on a combination of British plans and those from the AWPD, to create the Anglo-American Combined Bomber Offensive (CBO).[4][5]
Founding
On 20 June 1941, the United States Army Air Forces (USAAF) were established as a way to combine and streamline two conflicting air commands: GHQ Air Force and the Army Air Corps. Major General Henry H. Arnold commanded the USAAF and formed an Air Staff to lead it; within the Air Staff, the Air War Plans Division was established with Lieutenant Colonel Harold L. George at its head. George was to coordinate his planning efforts with the War Plans Division (WPD) of the War Department.[6]
Up to this point, the WPD was responsible for planning all aspects of Army and Army Air Corps expansion in the U.S.[6] George was challenged by WPD, which contested AWPD's and Air Staff's authority to make strategic plans. WPD recommended that AWPD should be limited to tactical planning, and that the Air Staff, in a subordinate role, should advise the WPD rather than make its own operational or strategic plans. George pushed for greater autonomy—he wished to prepare all plans for all air operations.[6]
On 9 July 1941, President Roosevelt asked Frank Knox, the Secretary of the Navy, and Henry L. Stimson, the Secretary of War, for an exploration of the total war production required for the United States to prevail in case of war.[1] The WPD, in order to project long-term numbers, realized that the Rainbow 5 plan would be used as a basis for production quantities, but it lacked detailed air power figures. Stimson requested of Robert A. Lovett, Assistant Secretary of War for Air,[7] that the USAAF be tapped for their ideas about production numbers. After some bureaucratic delay, the AWPD received the request.[1]
In early 1941, American, Canadian and British war planners convened in Washington D.C. for a series of secret planning sessions called the American–British Conference, or ABC-1, to determine a course of action should the United States become a belligerent in the war. An overarching strategy of Europe first was agreed to, where American energies would primarily be directed against Germany, Italy and their European conquests, during which a secondary defensive posture was to be held against Japan. Royal Air ForceAir Vice-MarshalJohn Slessor[8] and other airmen present at the conference agreed on the general concept of using strategic bombing by both British and American air units based in the United Kingdom to reduce Axis military power in Europe.[9] Incorporating this work in April 1941, the joint U.S. Army-Navy Board developed Rainbow 5, the final version of general military guidelines the U.S. would follow in case of war.[10]
At the beginning of August 1941, the AWPD consisted of only four officers: Harold L. George, Orvil Anderson, Kenneth Walker (each one a lieutenant colonel), and Major Haywood S. Hansell.[1] To help answer the urgent need for planning, George could have sent a couple of his air officers to WPD to assist them, following the standard Army policy since air warfare first arose in World War I. An air plan would have been made emphasizing tactical air coordination with ground forces,[11] one which targeted Axis military formations and supplies in preparation and support of an invasion.[8] George wished to implement the strategic bombing theories that had been debated and refined at the Air Corps Tactical School (ACTS) during the preceding decade, but was sure that the Army and the War Department would not accept a strategy that assumed air attack would prevail alone. Instead, he intended to implement a middle path which began with strategic air attack but contained allowances for the eventual support of a ground invasion.[8] In requesting autonomy to make his own plans, George gained approval from General Arnold and from General Leonard T. Gerow, head of the overworked WPD, who approved as long as AWPD held to the guidelines of ABC-1 and Rainbow 5.[11]
George sought out men he knew were bombing advocates. He obtained temporary help from five more air officers: Lieutenant Colonels Max F. Schneider and Arthur W. Vanaman, and Majors Hoyt S. Vandenberg, Laurence S. Kuter, and Samuel E. Anderson.[1] All but Samuel E. Anderson had passed through ACTS, where precision bombing theories were ascendant.[12] Orvil Anderson was assigned to continue with ongoing projects while the rest of the men concentrated on the new request. On 4 August 1941, the augmented AWPD set to work.[1]
George, Walker, Kuter, and Hansell provided the key concepts for the AWPD task force. George's vision was that the plan should not be a simple list of quantities of men and materiel—it should be a clear expression of the strategic direction required to win the war by use of air power.[13] The main feature of the plan was the proposal to use massive fleets of heavy bombers to attack economic targets, the choke points of Axis industry. Hansell, fresh from a fact-finding mission to England in which he was briefed on British appreciations of German industrial and military targets, immediately became immersed in the job of target selection.[9]
Munitions Requirements of the Army Air Forces to Defeat Our Potential Enemies, or AWPD-1, standing for "Air War Plans Division, plan number one",[14] was the first concrete result of AWPD; it was delivered on 12 August after nine days of preparation. The plan used industrial web theory to describe how air power could be used to attack vulnerable nodes in Germany's economy, including electrical power systems, transportation networks, and oil and petroleum resources.[1] The civil population of Berlin could be targeted as a final step to achieving enemy capitulation, but such an attack was optional: "No special bombardment unit [would be] set up for this purpose."[15]
The plan also described, in less detail, how to use air power to draw a defensive perimeter around the Western Hemisphere and around America's interests in Alaska, Hawaii, the Dutch East Indies and the Philippines in the Pacific Ocean. In the Atlantic, AWPD indicated bases be developed in Iceland, Newfoundland, and Greenland to augment bases in the United Kingdom.[1] Elsewhere, bases were to be established in India and staging areas arranged in Siberia.[1]
Finally, the plan detailed large tactical air formations to assist in an invasion of Europe and to fight in the land campaigns to follow, to be ready by Spring 1944—the same time that invasion forces would be ready.[8]
Army Chief of Staff General George Marshall approved AWPD-1 in September, as did Secretary of War Stimson.[8] Army planners were worried that both the Soviet Union and the United Kingdom would be defeated, and that an invasion of Europe would become remote. The strategy of weakening Germany by bombing, long before an invasion could be prepared, gave hope that America would not lose any allies in the interim.[8]
AWPD-2
On 9 September 1941, the president asked for more detail regarding allocation of aircraft based on estimates of peacetime production for the next nine months. In AWPD-2, Arnold and George designated two-thirds of the aircraft to be pooled for anti-Axis purposes such as Lend-Lease and one-third to be sent to the USAAF.[11]
Public knowledge
Senator Burton K. Wheeler compromised the secret plans in his wish to keep America out of the war.
Roosevelt incorporated the Army's, Navy's and Air Staff's detailed plans into an executive policy he called his "Victory Program". Roosevelt hoped to engage public opinion in favor of the Victory Program because the increase in production it promised meant more jobs and a healthier economy. Opponents of the policy included a powerful supporter of the isolationistAmerica First Committee, Senator Burton K. Wheeler. Wheeler obtained a copy of the Victory Program, classified Secret, from a source within the Air Corps, and on 4 December 1941 leaked the plan to two isolationist newspapers, the Chicago Tribune and the Washington Times-Herald.[8] Vocal public opposition to the plan ceased three days later on 7 December, when the Japanese attacked Pearl Harbor. Congress soon passed the Victory Program with few changes.
German agents monitoring American newspapers wired the compromised secret program to Berlin where Franz Halder, Chief of the German General Staff, realized its critical importance. On 12 December, Adolf Hitler issued Directive 39 which countered the American strategic bombing and invasion plans by massing air defenses around key industries and by greatly increasing Atlantic Ocean attacks so that an Allied invasion fleet could not be formed.[8] Hitler directed his forces opposing the Soviet Union to go on the defensive so that they could hold their ground at least cost. Four days later, after visiting the Eastern Front and seeing the extent of his strategic failures there, Hitler "angrily and irrationally rescinded Directive 39" and focused his armies once again on the attack.[8]
AWPD-4
After 7 December, all of America's former plans required revision—none had projected such early involvement in direct combat. Orvil Anderson was asked to rewrite the air plans. On 15 December, Anderson submitted AWPD-4, mostly a restatement of the goals of AWPD-1, but with augmented quantities to meet the greater needs of a two-front war. The number of combat aircraft was increased by 65%, and total aircraft production was more than doubled.[13]
AWPD-42
On 24 August 1942, in light of the grim global situation, President Roosevelt called for a major reassessment of U.S. air power requirements, "in order to have complete air ascendancy over the enemy."[16] The Japanese had expanded quickly in the Pacific Theater, North Africa was being rolled up by Rommel with Egypt threatened, Soviet forces were falling back against the German advances toward Stalingrad and the oilfields of the Caucasus, and German U-boats in the Atlantic sank 589 ships in early 1942.[17] On 25 August, Arnold received word of the president's request from Army Chief of Staff George Marshall.[16] The individual AWPD-1 team members had been reassigned to a wide variety of posts and duties, so to perform the reassessment Arnold recommended Hansell, recently made brigadier general. Marshall cabled Hansell in the UK, where he had been working under General Dwight D. Eisenhower as Air Planner, and under General Carl Andrew Spaatz as Deputy Theater Air Officer.[18][19] Marshall ordered Hansell to hurry back to AWPD and that "the results of the work of this group are of such far-reaching importance that it will probably determine whether or not we control the air."[17] Hansell brought with him VIII Bomber Command Chief of Intelligence Colonel Harris Hull and RAF Group Captain Bobby Sharp, as well as the little data compiled from five UK-based raids which had been flown by U.S. bombers.[16] Hansell was assisted on a consultative basis by George, Kuter and Walker, old AWPD-1 hands, and by Lieutenant Colonel Malcolm Moss, who was a sharp businessman in civil life. The team had just 11 days to finish the work.[17] Arnold was more closely involved than before in leading the group and formulating the new plan. Like AWPD-1, the new framework was based largely on untried bombing theory.[16] The report, entitled Requirements for Air Ascendancy, 1942, or AWPD-42, was submitted to the Joint Chiefs of Staff (JCS) on 6 September 1942.[19]Harry Hopkins had obtained his copy at 1am the day it was to be released, and Hopkins read it in time to tell Roosevelt over breakfast that the plan was sound. Roosevelt called Stimson to say he approved it, but Stimson hadn't had not seen it; nor had Marshall when Stimson called him. Hansell left hurriedly for England so that he would not have to face Marshall's anger at being caught unprepared.[20]
AWPD-42 was written under the assumption that the Soviet Union would be knocked out of the war, and that German forces in the East would then be brought to bear against the West. The plan thus assumed that German ground forces defending Europe would be numerically superior to Allied invasion forces, making invasion extremely costly and perhaps impossible. It was also assumed that two-front tension in the German economy would lessen, and Allied damage to Axis industry would be more easily absorbed. An increase in American air power was projected as the best way to reduce Axis industrial might. An air campaign against two major European objectives was encompassed: first to paralyze Axis industrial power, and second to defeat Axis air power.[16] Axis aircraft factories and aircraft engine plants were to be targeted during 1943–1944 so that, in the spring of 1944, an invasion of Europe could be undertaken.[16]
A U.S. Navy patrol bomber in 1943: the PB4Y-1 Liberator. Under AWPB-42, the aircraft would have been flown by Army Air Forces, not the Navy.
In the president's request, he had not asked for the combined numbers of U.S. Army and U.S. Navy aircraft; he asked for the "number of combat aircraft by types which should be produced in this country for the Army and our Allies in 1943..."[21] This meant that the Navy's aircraft needs, which were significant, were not requested, but that the aircraft needs for America's allies would be included, allies that were to receive a certain number of Navy-type aircraft. Hansell decided to make his plan wholly inclusive of all American aircraft requirements—Army, Navy, and Allied—so that there would be no misunderstanding about how aircraft-producing resources would be allocated. Hansell accepted the aircraft production plans that the Navy submitted, but with one vital change: the four-engined bombers the Navy wanted would be built as Air Corps bombers, flown by USAAF units.[21]
The Navy was not at all satisfied with AWPD-42. The Navy's intention to divert 1250 land-based heavy bombers from AAF requirements, to use for long-range patrol and for attacking enemy vessels, was dismissed in favor of USAAF flights to achieve the same goals. The Navy expected that command and control differences between the services, as well as differing targeting preferences, would create impossible barriers to successful employment of the notional USAAF patrol bombers against enemy naval forces. The Navy flatly rejected AWPD-42, which barred acceptance by the JCS, but by 15 October 1942 the president had established it as the U.S.'s aircraft manufacturing plan, saying that the lofty aircraft production proposal "will be given the highest priority and whatever preference is needed to insure its accomplishment."[16]
Quantities
AWPD-1 called for the production of 61,800 aircraft, of which 37,000 would be trainers and 11,800 would be for combat.[13] The remaining 13,000 would be military transport aircraft and other types.[13] Of the combat aircraft, 5000 were to be heavy and very heavy bombers.[13] AWPD-4 increased the combat aircraft to 19,520 and the total to 146,000.[13] Numbers increased again in AWPD-42, which proposed that combat aircraft should top 63,000 in 1943.[16] Total U.S. aircraft production, including for the Navy, was set at 139,000 until it was realized that the goal could not be reached by American industry. 107,000 was instead proposed.[16]
AWPD-1 projected a force of 2.1million airmen. AWPD-42 increased this to 2.7million.[22]
In drawing up AWPD-1, George had predicted that two very heavy bombers that were on the drawing board, the Boeing B-29 Superfortress and the Consolidated-Vultee B-36, would be ready in time to take part in the attack on Germany. Delays in both programs kept them from consideration in Europe. In AWPD-42, the B-29 was shifted to attacks on Japan, and the B-36 development at Consolidated-Vultee was slowed in favor of manufacturing more B-24 Liberators.[22] The extra-long range of the B-36 would not be needed now that the United Kingdom appeared secure from attack.[17]
AWPD-1 identified 154 targets in four areas of concern: electric power, transportation, petroleum and the Luftwaffe, the German Air Force.[8] An arbitrary time frame was given, suggesting that six months after the strategic bombing forces were ready for large-scale attacks, the enemy targets would be destroyed.[8]
AWPD-42 called for 177 targets to be hit, covering seven strategic areas, with the highest priority being enemy aircraft production.[16] Other priorities were submarine pens and building yards, transportation systems, electric power generation and distribution, the petroleum industry, aluminum refining and manufacture, and the synthetic rubber industry.[16] Hansell considered it a mistake to remove electricity from the top priority, and worse still to place submarine pens there.[20] Political expediency dictated the shift in target priorities, not pure strategic considerations.[20]
Subsequent groups
Targeting proved a difficult task for AWPD—attaining the proper selection required a wide range of intelligence input as well as operational considerations. In December 1942, Arnold set up the Committee of Operations Analysts (COA) to better study the problem. The COA performed target selection for the USAAF.[23]
In January 1943 at the Casablanca Conference, the Combined Chiefs of Staff agreed to begin the Combined Bomber Offensive (CBO) in June and set targeting priorities. Based on these priorities but with some changes, the British Air Ministry issued the Casablanca directive on 4 February, targeting the German military, German industrial and economic systems, and German morale.[24] More methodically, USAAF General Ira C. Eaker assembled an Anglo-American planning team to take the COA's list of targets and schedule them for combined bomber operations. This unnamed group, sometimes called the CBO Planning Team,[4] was led by Hansell and included among others USAAF Brigadier General Franklin Anderson and RAF Air Commodore Sidney Osborne Bufton. Finished in April 1943, the plan recommended 18 operations during each three-month phase against a total of 76 specific targets.[25] The Combined Bomber Offensive began on 10 June 1943.[26]
In late 1944, the COA was superseded by the Joint Target Group, a combined service unit organized by the JCS.[23]

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.
The United States Strategic Bombing Survey (USSBS) was a written report created by a board of experts assembled to produce an impartial assessment of the effects of the Anglo-American strategic bombing of Nazi Germany during the European theatre of World War II. After publishing the report in 1945, the Survey members then turned their attention to the war efforts against Imperial Japan during the Pacific War, including a separate section on the recent use of the atomic bomb in attacks on two Japanese cities.
Bomber Command is an organisational military unit, generally subordinate to the air force of a country. The best known were in Britain and the United States. A Bomber Command is generally used for strategic bombing, and is composed of bombers.
In military tactics, close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.
The Norden Mk. XV, known as the Norden M series in U.S. Army service, is a bombsight that was used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars. It was an early tachometric design, which combined optics, a mechanical computer, and an autopilot for the first time to not merely identify a target but fly the airplane to it. The bombsight directly measured the aircraft's ground speed and direction, which older types could only estimate with lengthy manual procedures. The Norden further improved on older designs by using an analog computer that continuously recalculated the bomb's impact point based on changing flight conditions, and an autopilot that reacted quickly and accurately to changes in the wind or other effects.
World War II (1939–1945) involved sustained strategic bombing of railways, harbours, cities, workers' and civilian housing, and industrial districts in enemy territory. Strategic bombing as a military strategy is distinct both from close air support of ground forces and from tactical air power. During World War II, many military strategists of air power believed that air forces could win major victories by attacking industrial and political infrastructure, rather than purely military targets. Strategic bombing often involved bombing areas inhabited by civilians, and some campaigns were deliberately designed to target civilian populations in order to terrorize them and disrupt their usual activities. International law at the outset of World War II did not specifically forbid the aerial bombardment of cities – despite the prior occurrence of such bombing during World War I (1914–1918), the Spanish Civil War (1936–1939), and the Second Sino-Japanese War (1937–1945).
Precision bombing is the attempted aerial bombing of a target with some degree of accuracy, with the aim of maximising target damage or limiting collateral damage. Its strategic counterpart is carpet bombing. An example would be destroying a single building in a built up area causing minimal damage to the surroundings. Precision bombing was initially tried by both the Allied and Central Powers during World War I, however it was found to be ineffective because the technology did not allow for sufficient accuracy. Therefore, the air forces turned to area bombardment, which killed civilians. Since the War, the development and adoption of guided munitions has greatly increased the accuracy of aerial bombing. Because the accuracy achieved in bombing is dependent on the available technology, the "precision" of precision bombing is relative to the time period.
The Pointblank directive authorised the initiation of Operation Pointblank, the code name for the part of the Allied Combined Bomber Offensive intended to cripple or destroy the German aircraft fighter strength, thus drawing it away from frontline operations and ensuring it would not be an obstacle to the invasion of Northwest Europe. The Pointblank directive of 14 June 1943 ordered RAF Bomber Command and the U.S. Eighth Air Force to bomb specific targets such as aircraft factories, and the order was confirmed when Allied leaders met at the Quebec Conference in August 1943. Up to that point, the RAF and USAAF had mostly been attacking the German industry in their own way – the British by broad night attacks on industrial areas, and the US in "precision attacks" by day on specific targets. The operational execution of the Directive was left to the commanders of the forces. As such, even after the directive, the British continued their night attacks. The majority of the attacks on German fighter production and combat with the fighters were conducted by the USAAF.
The military history of the United States during World War II covers the nation's role as one of the major Allies in their victory over the Axis Powers. The United States is generally considered to have entered the conflict with the 7 December 1941 surprise attack on Pearl Harbor by the Empire of Japan and exited it with the 2 September 1945 surrender of Japan. During the first two years of World War II, the US maintained formal neutrality, which was officially announced in the Quarantine Speech delivered by US President Franklin D. Roosevelt in 1937. While officially neutral, the US supplied Britain, the Soviet Union, and China with war materiel through the Lend-Lease Act signed into law on 11 March 1941, and deployed the US military to replace the British forces stationed in Iceland. Following the 4 September 1941 Greer incident involving a German submarine, Roosevelt publicly confirmed a "shoot on sight" order on 11 September, effectively declaring naval war on Germany and Italy in the Battle of the Atlantic. In the Pacific Theater, there was unofficial early US combat activity such as the Flying Tigers.
The Combined Bomber Offensive (CBO) was an Allied offensive of strategic bombing during World War II in Europe. The primary portion of the CBO was directed against Luftwaffe targets which was the highest priority from June 1943 to 1 April 1944. The subsequent highest priority campaigns were against V-weapon installations and petroleum, oil, and lubrication (POL) plants. Additional CBO targets included railyards and other transportation targets, particularly prior to the invasion of Normandy and, along with army equipment, in the final stages of the war in Europe.
During the Pacific War, Allied forces conducted air raids on Japan from 1942 to 1945, causing extensive destruction to the country's cities and killing between 241,000 and 900,000 people. During the first years of the Pacific War these attacks were limited to the Doolittle Raid in April 1942 and small-scale raids on military positions in the Kuril Islands from mid-1943. Strategic bombing raids began in June 1944 and continued until the end of the war in August 1945. Allied naval and land-based tactical air units also attacked Japan during 1945.
Brigadier General Kenneth Newton Walker was a United States Army aviator and a United States Army Air Forces general who exerted a significant influence on the development of airpower doctrine. He posthumously received the Medal of Honor in World War II.
Haywood Shepherd Hansell Jr. was an American general officer in the United States Army Air Forces (USAAF) during World War II, and later the United States Air Force. He became an advocate of the doctrine of strategic bombardment, and was one of the chief architects of the concept of daylight precision bombing that governed the use of airpower by the USAAF in the war.
The Allied oil campaign of World War II was an aerial bombing campaign conducted by the RAF and the USAAF against facilities supplying Nazi Germany with petroleum, oil, and lubrication (POL) products. It formed part of the immense Allied strategic bombing effort during the war. The targets in Germany and in Axis-controlled Europe included refineries, synthetic-fuel factories, storage depots and other POL-infrastructure.
The Bomber Mafia were a close-knit group of American military men who believed that long-range heavy bomber aircraft in large numbers were able to win a war. The derogatory term "Bomber Mafia" was used before and after World War II by those in the military who did not share their belief, and who were frustrated by the insistence of the men that the heavy bomber should take a primary position in planning and funding.
Industrial web theory is the military concept that an enemy's industrial power can be attacked at nodes of vulnerability, and thus the enemy's ability to wage a lengthy war can be severely limited, as well as his morale—his will to resist. The theory was formulated by American airmen at the Air Corps Tactical School (ACTS) in the 1930s.
Air warfare was a major component in all theaters of World War II and, together with anti-aircraft warfare, consumed a large fraction of the industrial output of the major powers. Germany and Japan depended on air forces that were closely integrated with land and naval forces; the Axis powers downplayed the advantage of fleets of strategic bombers and were late in appreciating the need to defend against Allied strategic bombing. By contrast, Britain and the United States took an approach that greatly emphasized strategic bombing and tactical control of the battlefield by air as well as adequate air defenses. Both Britain and the U.S. built substantially larger strategic forces of large, long-range bombers. Simultaneously, they built tactical air forces that could win air superiority over the battlefields, thereby giving vital assistance to ground troops. The U.S. Navy and Royal Navy also built a powerful naval-air component based on aircraft carriers, as did the Imperial Japanese Navy; these played the central role in the war at sea.
During World War II, a series of Japanese air attacks on the Mariana Islands took place between November 1944 and January 1945. These raids targeted United States Army Air Forces (USAAF) bases and sought to disrupt the bombing of Japan by Boeing B-29 Superfortress heavy bombers operating from the islands. The Japanese lost 37 aircraft during this operation, but destroyed 11 B-29s and damaged a further 43. Preparations were also made for commando raids on the bases in early and mid-1945 but these did not go ahead.
On the night of 9/10 March 1945, the United States Army Air Forces (USAAF) conducted a devastating firebombing raid on Tokyo, the Japanese capital city. This attack was code-named Operation Meetinghouse by the USAAF and is known as the Tokyo Great Air Raid in Japan. Bombs dropped from 279 Boeing B-29 Superfortress heavy bombers burned out much of eastern Tokyo. More than 90,000 and possibly over 100,000 Japanese people were killed, mostly civilians, and one million were left homeless, making it the most destructive single air attack in human history. The Japanese air and civil defenses proved largely inadequate; 14 American aircraft and 96 airmen were lost.
Operation Boomerang was a partially successful air raid by the United States Army Air Forces' (USAAF) XX Bomber Command against oil refining facilities in Japanese-occupied Dutch East Indies during World War II. The attack took place on the night of 10/11 August 1944 and involved attempts to bomb an oil refinery at Palembang and lay mines to interdict the Musi River.
