109-571: The IV Corps Observation Group was an Air Service, United States Army unit that fought on the Western Front during World War I . It was demobilized on 12 May 1919. There is no modern United States Air Force unit that shares its lineage and history. The IV Corps Observation Group was formally organized on 1 July 1918 by the First Army Air Service at Ourches Aerodrome , France, although its first personnel were organized on 27 June. It

Kenly brought back from France to be its head, to separate supervision of aviation from the duties of the Chief Signal Officer. Less than a month later, Wilson used a war powers provision of the Overman Act of May 20, 1918, to issue Executive Order No. 2862 that suspended for

327-508: A daily report for all planned patrols by his division. He also coordinated all technical matters between and Squadron and assigned Division. During the Meuse-Argonne offensive , Group aircraft began to be equipped with bomb racks, and, along with photographic missions, began attacking enemy traffic centers, dropping leaflets, and machine-gunning enemy infantry formations. From time to time, pilots and observers would be sent to infantry units on

436-535: A final plan for 202 by June 1919. In Pershing's view, the two functions of the AEF's Air Service were to repel German aircraft and conduct observation of enemy movements. The heart of the proposed force would be its 101 observation squadrons (52 corps observation and 49 army observation), to be distributed to three armies and 16 corps. In addition, 60 pursuit squadrons, 27 night-bombardment squadrons, and 14 day-bombardment squadrons were to conduct supporting operations. Without

545-489: A highly publicized personal investigation by Gutzon Borglum , a harshly vocal critic of the board. Borglum had exchanged letters with President Wilson, a personal friend, from which he assumed an appointment to investigate had been authorized, which the administration soon denied. Both the U.S. Senate and the Department of Justice began investigations into possible fraudulent dealings. President Wilson also acted by appointing

654-634: A new base set up by Third Army. At Sinzing the Group received replacement squadrons which were transferred from Toul, those being the 85th, 278th and 354th, the 85th formerly being assigned to the Group in France. After a considerable amount of work, training re-commenced at Sinzing on 5 May 1919. A week later, the entire Third Army Air Service, excepting that of the III Corps 138th Aero Squadron, one air park, and one construction squadron, were relieved from further duty with

763-515: A permanent part of the air forces. Observation planes often operated individually, as did pursuit pilots to attack a balloon or to meet the enemy in a dogfight . However the tendency was toward formation flying, for pursuit as well as for bombardment operations, as a defensive tactic. The dispersal of squadrons among the army ground units (each corps and division had an observation squadron attached) made coordination of air activities difficult, so that squadrons were organized by functions into groups ,

872-874: A separate aviation department to act as the centralized authority for decision-making, both the War and the Navy Departments opposed it, and on October 1, 1917, Congress instead legalized the existence of the APB and changed its name to the " Aircraft Board ", transferring its functions from the Council of National Defense to the secretaries of War and the Navy. Even so, the Aircraft Board in practice had little control over procurement contracts and functioned mostly as an information provider between industrial, governmental, and military entities. Nor did

981-482: A separate executive bureau to provide the aircraft needed. This arrangement lasted only until the War Department implemented the executive order on May 24 by issuing General Order No. 51 to coordinate the two independent agencies, with an eventual goal of creating a Director of Air Service . (The term "Air Service" had been in use in France since June 13, 1917, to describe the function of aviation units attached to

1090-508: A series of legislation in the next three months that appropriated huge sums for development of military aviation, including the largest single appropriation for a single purpose to that time, $ 640 million in the Aviation Act (40 Stat . 243), passed July 24, 1917. By the time the bill passed, the term Air Service was in widespread if unofficial usage to collectively describe all aspects of Army aviation. Although it considered creation of

1199-416: The 168th Aero Squadron , located at Croix-de-Metz Aerodrome , Toul, was assigned to the group. It was a newly organized unit and had just arrived at the front. On 14 October 1918, the Group was relieved from First Army and transferred to the newly organized Second Army Air Service . This was to give Second Army some experienced units in preparation for the upcoming Meuse-Argonne offensive . By this time,

1308-601: The 94th Pursuit Squadron scored. The first mission by an American squadron across the lines occurred April 11, when the 1st Aero Squadron, led by its commander, Major Ralph Royce , flew a photo reconnaissance mission to the vicinity of Apremont . The first American balloon group arrived in France on December 28, 1917. It separated into four companies that were assigned individually to training centers and instructed in French balloon procedures, then equipped with Caquot balloons, winches, and parachutes. The 2d Balloon Company joined

1417-554: The Curtiss Jenny as the primary trainer. Primary flying training school usually produced a candidate for commissioning in 15 to 25 hours of flight. At the assurance of the French that they could be rapidly trained in all phases, 1,700 cadets who had graduated from ground school were sent to Europe to undertake the entire flying portion of their training in Great Britain , France , and Italy . In December 1917, after receiving 1,400 of

1526-751: The Lafayette Escadrille and Lafayette Flying Corps . The first U.S. aviator killed in action during aerial combat occurred March 8, 1918, when Captain James E. Miller, commanding the 95th Pursuit Squadron , was shot down while on a voluntary patrol near Reims . The first aerial victory in an American unit was by 1st Lt. Paul F. Baer of the 103rd Aero Squadron, and formerly a member of the Lafayette Flying Corps, on March 11. The first victories credited to American-trained pilots came on April 14, 1918, when Lieutenants Alan F. Winslow and Douglas Campbell of

1635-470: The Western Front during World War I as part of the Air Service, Second United States Army . It was demobilized in France on 15 April 1919. There is no modern United States Air Force unit that shares its lineage and history. Organized at Saizerais Airfield , France on 23 October 1918. At the time the group was being organized, the airfield was under construction, although it had been previously used by

1744-413: The mass production methods of the automotive industry , which used considerable amounts of metallic materials instead, and the priority of mass-producing spare parts was neglected. Though individual areas within the aviation industry responded well, the industry as a whole failed. Efforts to mass-produce European aircraft under license largely failed because the aircraft, made by hand, were not amenable to

1853-643: The "Equipment Division" of the Signal Corps exercise such control. Established by the Office of the Chief Signal Officer (OCSO) as one of the operating components of the Aviation Section, its task was to unify and coordinate the various agencies involved but its head was a commissioned former member of the APB who did nothing to create any effective coordination. Moreover, the largely wood and fabric airframe designs of World War I did not lend themselves to being made with

1962-480: The "Million-Dollar Guard". The backlog was finally cleared by opening an Air Service primary school at Tours and devoting part of the advanced school at Issoudun to preliminary training for a period of time. The U.S. training program produced more than 10,000 pilots as new first lieutenants in the Signal Officers Reserve Corps (S.O.R.C.). 8,688 received ratings of Reserve Military Aviator in

2071-471: The 11th Photographic and an intelligence squadron was assigned to the Group. In the afternoon of the 23rd, seven pilots and seven observers were transferred from the 8th Squadron to the 354th along with eight aircraft allowing the squadron to commence operations at once. The 8th was assigned to the Sixth Corps Artillery for photographic and command work. The 354th was assigned to the 92d Division; at

2180-419: The 1st Pursuit Group of four pursuit squadrons relocated from Selfridge Field, Michigan, to add their weight to the effort. Collectively the three groups (the entire combat strength of the Air Service in the continental United States) comprised the 1st Wing . In January 1920 only the surveillance group continued the patrols, which gradually diminished until June 1921 when they ceased entirely. Another group

2289-632: The 3rd and 4th Regiments reorganized, delaying their deployment until the end of July. By the Armistice all four regiments were configured as aircraft repair and maintenance units, and designated Air Service Mechanics Regiments . The primary aircraft used by the AEF at the front (the "Zone of Advance") were the SPAD XIII (877), Nieuport 28 (181), and SPAD VII (103) as pursuit aircraft, the DeHaviland DH-4B (696) and Breguet 14 (87) for daylight bombing, and

2398-470: The 8th Aero was transferred along with the 92d Division on 23 October. On 4 November, the 85th Aero Squadron was assigned to the Group. It was initially assigned to the Manonville Aerodrome , but was moved back to Toul on 10 November. Newly organized, it flew only two missions over the line prior to the Armistice. On 10 November, the 258th Aero Squadron was assigned and moved to Manonville; however,

2507-533: The 9th Observation, was formed. The 7th Bombardment and 8th Fighter Groups were designated but not activated until the end of the decade. Sect. 13a. There is hereby created an Air Service. The Air Service shall consist of one Chief of Air Service with the rank of major-general, one assistant with the rank of brigadier-general, 1,514 officers in grades from colonel to second lieutenant, inclusive, and 16,000 enlisted men, including not to exceed 2,500 flying cadets... — Section 13a, Public Law 242, 41 Stat . 759 With

2616-833: The AEF accelerated in December and January, and all but two of these squadrons returned to the United States. Mitchell was replaced in January as commander of the Third Army Air Service by Col. Harold Fowler , a combat veteran of the Royal Flying Corps and former commander of the American 17th Pursuit Squadron. On April 15, 1919, the Second Army Air Service in France also closed down. Its former air units were transferred to

2725-550: The Air Service Concentration Barracks at Saint-Maixent received all newly arrived Air Service troops, distributing them to 26 training fields and schools throughout the central and western regions of the country. Flying training schools, equipped with 2,948 airplanes, supplied 1,674 fully trained pilots and 851 observers to the Air Service, with 1,402 pilots and 769 observers serving at the front. The observers trained in France included 825 artillery officers from

2834-556: The Air Service branch, receiving new commissions. During the war its responsibilities and functions were split between two coordinate agencies, the Division of Military Aeronautics (DMA) and the Bureau of Aircraft Production (BAP), each reporting directly to the Secretary of War, creating a dual authority over military aviation that caused unity of command difficulties. The seven-year history of

2943-577: The Air Service consisted of 185 flying, 44 construction, 114 supply, 11 replacement, and 150 spruce production squadrons; 86 balloon companies; six balloon group headquarters; 15 construction companies; 55 photographic sections; and a few miscellaneous units. Its personnel strength was 19,189 officers and 178,149 enlisted men. Its aircraft inventory consisted primarily of Curtiss JN-4 trainers, de Havilland DH-4B scout planes, SE-5 and Spad S.XIII fighters, and Martin MB-1 bombers. Complete demobilization of

3052-631: The Air Service destroyed 756 enemy aircraft and 76 balloons in combat. 17 balloon companies also operated at the front, making 1,642 combat ascensions. 289 airplanes and 48 balloons were lost in battle. The Air Service was the first form of the air force to have an independent organizational structure and identity. Although officers concurrently held rank in various branches, after May 1918 their branch designation in official correspondence while on aviation assignment changed from "ASSC" (Aviation Section, Signal Corps) to "AS, USA" (Air Service, United States Army). After July 1, 1920, its personnel became members of

3161-543: The Air Service of the American Expeditionary Force , a separate entity under commanding General John J. Pershing that conducted the combat operations of U.S. military aviation, began field service in the spring of 1918. By the end of the war, the Air Service used 45 squadrons to cover 137 kilometers (85 miles) of front from Pont-à-Mousson to Sedan . 71 pursuit pilots were credited with shooting down five or more German aircraft while in American service. Overall

3270-467: The Air Service to that desired by the General Staff to maintain the aviation arm as an auxiliary component controlled by ground commanders in furtherance of the mission of the infantry. A Chief of Air Service was authorized with the rank of major general to replace the previous Director of Air Service , and an assistant chief created in the rank of brigadier general (from 1920 to 1925 this position

3379-412: The Air Service was accomplished within a year. By November 22, 1919, the Air Service had been reduced to one construction, one replacement, and 22 flying squadrons; 32 balloon companies; 15 photographic sections; and 1,168 officers and 8,428 enlisted men. The combat strength of the Air Service was only four pursuit and four bombardment squadrons. Although the leaders of the reorganized Air Service persuaded

In all, 211 squadrons of all types trained in Great Britain, with 71 arriving in France before the Armistice. At its peak establishment in November 1918, the Air Service was based at 31 stations in the Services of Supply (rear areas) and 78 aerodromes in the Zone of Advance (combat area). The 740 combat airplanes equipping

Arnold , Assistant Director of the DMA, was ordered to put together a daily route for moving mail by airplane between New York City , Philadelphia , and Washington, D.C. He assigned the task to the Executive Officer for Flying Training, Major Reuben H. Fleet . The Air Service, using six pilots (four instructor pilots and two new graduates) and six Curtiss JN-4H "Jenny" trainers modified to carry mail, began

In August, the Senate completed its investigation of the Aircraft Board, and while it found no criminal culpability, it reported that massive waste and delay in production had occurred. As a result, the Director of Aircraft Production (who was also chairman of the Aircraft Board), John D. Ryan,

3924-573: The American aircraft fleet. Of aircraft manufactured in America, the de Havilland DH-4B (3,400) was the most numerous, although only 1,213 were shipped overseas, and only 1,087 of those assembled, most used in observation units. The facilities of the Air Service in the United States totaled 40 flying fields, 8 balloon fields, 5 schools of military aeronautics, 6 technical schools, and 14 aircraft depots. 16 additional training schools were located in France, and officers also trained at three schools operated by

4033-478: The Armistice was announced the next day and it flew no combat missions with the Group. After the Armistice with Germany and the conclusion of the war, squadron flying continued on a limited basis to keep the pilots proficient in their skills. However, the main endeavors of the Group was Army administrative paperwork. During the weeks following the signing of the Armistice, the IV Corps Observation Group

4142-704: The Army and Navy. Aided by a wave of pacifism following the war that drastically cut military budgets, opponents of an independent air force prevailed. The Air Service was renamed the Army Air Corps in 1926 as a compromise in the continuing struggle. Although war in Europe prompted Congress to vastly increase the appropriations for the Aviation Section in 1916, it nevertheless tabled a bill proposing an aviation department incorporating all aspects of military aviation. The declaration of war against Germany on April 6, 1917, putting

4578-407: The Aviation Section developed a maintenance organization of four large units termed Motor Mechanics Regiments, Signal Corps , each regiment consisting of four battalions of five companies totaling more than 3,600 men. The key innovative element was the use of junior officers recruited from the automobile industry as "technical officers" to supervise maintenance. In February 1918, Colonel S.D. Waldon of

Balloon companies operated the French-designed Goodyear Type R, a winch-tethered, hydrogen -filled, captive " Caquot " observation balloon of 32,200 cubic-foot (912 cubic meters) capacity, deploying one balloon per company. The United States adopted a national insignia for all military aircraft in May 1917 using

4905-549: The First Army infantry was advancing. It flew observation missions over the enemy lines, taking photographic strip photos over the entire front. One of the main missions was to photograph the entire corps line front to a depth of 10 km inside enemy territory, about 600 square km. Headquarters remained at Ménil-la-Tour until 10 October when it moved along with IV Corps HQ to Bocq along the Belgian-French border. On 12 October,

5014-555: The French 91st Balloon Company at the front near Royaumeix on February 26, 1918. On March 5 it took over the line and began operations supporting the U.S. 1st Division , becoming the "first complete American Air Service unit in history to operate against an enemy on foreign soil." By the beginning of the Meuse-Argonne Offensive the Air Service AEF consisted of 32 squadrons (15 pursuit, 13 observation, and 4 bombing) at

Its aircraft landed on the field and the squadron commenced operations that afternoon. A second squadron, the 354th Aero, arrived on 23 October. The 354th was a new squadron which had just been assigned to combat duty. Along with the two flying squadrons,

5232-621: The French at Issoudun, Clermont-Ferrand , and Tours, respectively. By November 11, 1918, the Air Service both overseas and domestically had 195,024 personnel (20,568 officers; 174,456 enlisted men) and 7,900 aircraft, constituting five per cent of the United States Army. 32,520 personnel served in the Bureau of Aircraft Production and the remainder in the Division of Military Aeronautics. The Air Service commissioned over 17,000 reserve officers. More than 10,000 mechanics were trained to service

By July 1924, the Air Service inventory was 457 observation planes, 55 bombers, 78 pursuit planes, and 8 attack aircraft, with trainers to make the total number 754. The Air Service replaced its wartime structure with

5450-587: The German Garrison. Offices were set up in Third Army Headquarters Building. Upon the command's arrival in Germany, an airfield was constructed on the former parade ground of Fort Kaiser Alexander for aircraft squadrons being assigned to Coblenz. At Coblenz, the Group co-occupied the airfield with several squadrons assigned directly to Third Army Air Service. IV Corps Observation Group consisted of

A major air depot at Colombey-les-Belles ; three other maintenance depots at Behonne , LaTrecey , and Vinets ; four supply depots at Clichy , Romorantin , Tours , and Is-sur-Tille ; and 12 air park squadrons maintained the combat and training forces. Aircraft acquired from European sources were accepted at Aircraft Acceptance Park No. 1 at Orly , while those shipped from

5886-475: The Signal Corps returned from observing British factory and field methods in aviation operations, just as the Bureau of Aircraft Production concluded that the French were unable to meet their aircraft production goals. Waldon recommended that the regiments be reorganized for aircraft instead of automobile mechanics. The change came too late to affect the 1st and 2nd Regiments, which landed in France in March 1918, but both

The reorganization of the Aviation Section had been inadequate in resolving problems in training, leaving the United States totally unprepared to fight an air war in Europe. The Aviation Section consisted of 131 officers, 1087 enlisted men, and approximately 280 airplanes. The administration of President Woodrow Wilson created an advisory Aircraft Production Board in May 1917, consisting of members of

6540-447: The armistice, the AEF actually received 4,874 aircraft from the French, in addition to 258 from Great Britain, 19 from Italy, and 1,213 of American manufacture, for a total of 6,364 airplanes. 1,664 were classed as training craft. The United States recognized that French skilled labor was severely limited by war casualties, and promised to train and deploy 7,000 automobile mechanics to aid the French Motor Transport Corps.

On May 5, 1918, the 1st Pursuit Group was formed, and by the armistice the AEF had 14 heavier-than-air groups (7 observation, 5 pursuit, and 2 bombardment). Of these 14 groups, only the 1st Pursuit and 1st Day Bombardment Groups had their lineage continued into

7739-461: The formation of six permanent groups in 1919, four of which were based in the United States and two overseas. The first of the new groups, the Army Surveillance Group, was organized in July to direct the operations of three squadrons patrolling the border with Mexico, where revolution had broken out, from Brownsville, Texas to Nogales, Arizona . In addition, the 1st Day Bombardment Group was formed to control four bombardment squadrons at Kelly, while

7848-497: The front indicate that two aviators lose their lives in accidents for each aviator killed in battle." — Report of the Secretary of War, 1919 The Air Service, American Expeditionary Force, totaled 78,507 personnel (7,738 officers and 70,769 enlisted men) at the armistice. Of this total, 58,090 served in France; 20,075 in England; and 342 in Italy. Balloon troops made up approximately 17,000 of

7957-517: The front of the IV Army Corps had moved from Lake Lachaunssee to Éply . The 135th Aero Squadron was assigned to support the 28th Division and the left group of the Corps Artillery. The 8th Squadron was assigned to the right group of Corps Artillery, the 7th and 92d Divisions. The 168th was assigned to training missions in the rear to familiarize its pilots and observers with the sector. When, in

8066-702: The front, while by November 11, 1918, 45 squadrons (20 pursuit, 18 observation, and 7 bombardment ) had been assembled for combat. During the war, these squadrons played important roles in the Battle of Château-Thierry , the St-Mihiel Offensive , and the Meuse-Argonne. Several units, including the 94th Pursuit Squadron under the command of Capt. Eddie Rickenbacker , and the 27th Pursuit Squadron , which had "balloon buster" 1st Lt. Frank Luke as one of its pilots, achieved distinguished records in combat and remained

8175-485: The ground schools began 21 May 1917 and concluded 14 July 1917, graduating 147 cadets and enrolling another 1,430. By mid-November, 3,140 had graduated and more than 500 had become rated officers . Out of more than 40,000 applicants, 22,689 were accepted and 17,540 completed ground school training. Approximately 15,000 advanced to primary (preliminary) flying training, a six-to-eight week course conducted by both military and civilian flying instructors, using variants of

8284-531: The ground. Artillery units were trained in the use of aircraft for adjusting barrages. As many officers and non-commissioned officers as possible were taken up in airplanes to view the exercises. Radio officers were taken up to perform duties in actual exercises. In addition, another important mission at Coblenz was the testing and evaluation of captured German aircraft. The intelligence and engineering departments analyzed their design and construction, as well as disassembling of German aircraft for evaluation. Pilots of

8393-1038: The infantry divisions who volunteered to fill a critical shortage in 1918. After the Armistice, the schools graduated 675 additional pilots and 357 observers to serve with the Third Army Air Service in the Army of Occupation . The 3rd Aviation Instruction Center at Issoudun provided 766 pursuit pilots. 169 students and 49 instructors died in training accidents. Balloon candidates made 4,224 practice ascensions while training. Air Service combat losses were 289 airplanes and 48 balloons with 235 airmen killed in action, 130 wounded, 145 captured, and 654 Air Service members of all ranks dead of illness or accidents. Air Service personnel were awarded 611 decorations in combat, including 4 Medals of Honor and 312 Distinguished Service Crosses (54 were oak leaf clusters ). 210 decorations were awarded to aviators by France, 22 by Great Britain, and 69 by other nations. Executive Order 3066, issued by President Wilson on March 19, 1919, formally consolidated

8502-482: The line and spend two days in the trenches. A liaison school was maintained in which personnel on the line would be trained and be demonstrated contact with airplanes, and ended with an all day infantry liaison exercise, along with a battle order. The men were taught how to signal aircraft, use of flares and fireworks, and manipulation of ground panels. Upon the formation of the VI Corps Observation Group ,

8611-663: The mail service on May 15. It later extended the route to Boston and added Curtiss R-4LMs to its small fleet, carrying mail until August 12, 1918, when the U.S. Post Office took over. Sent to Europe in March 1917 as an observer, Lieutenant Colonel Billy Mitchell arrived in Paris just four days after the United States declared war and established an office for the American "air service." Upon his arrival in France in June 1917, American Expeditionary Force commanding general John J. Pershing met with Mitchell, who advised Pershing that his office

8720-541: The main endeavors of the Group was Army administrative paperwork. The 8th Aero Squadron was ordered to proceed to the 2nd Aviation Instruction Center on Tours Aerodrome on 21 November. Second Army was ordered demobilized on 15 April 1919, and the 354th was transferred to the IV Corps Observation Group , Third Army for occupation duty in the Rhineland, Germany. Headquarters personnel were subsequently assigned to

8829-622: The markings of enemy aircraft , in early 1918 a red, blue, and white roundel similar to those used by the Allied Powers, in the former color arrangement of the defunct Imperial Russian Air Service , was instead ordered painted on all U.S. aircraft operating in Europe, remaining in effect until 1919. On May 6, 1918 Foulois established a policy authorizing creation of emblems for aviation units, and ordered all squadrons to create an official insignia to be painted on each side of an airplane fuselage: "The squadron will design their own insignia during

8938-626: The more precise American manufacturing methods. At the same time the Aeronautical Division of the OCSO was renamed the Air Division with continued responsibility for training and operations but with no influence on acquisition or doctrine. In the end the decision-making process in aircraft procurement was badly fragmented and production on a large scale proved impossible. The Aircraft Board came under severe criticism for failure to meet goals or its own claims of aircraft production, followed by

9047-522: The move to Germany, moving to Mercy-le-Haut , France. This town had been held for years by the Germans. On 4 December, Headquarters moved to Euren, near Trier, Germany. Corps Headquarters moved still further into Germany when orders were received to move to Coblenz on 27 December. Upon arrival, the Headquarters was assigned to Fort Kaiser Alexander for billeting and vehicle garaging, which was formerly used by

9156-563: The necessity of forming an "air force" to centralize control over tactical aviation. In the St-Mihiel Offensive, commencing September 12, 1918, the American and French offensive against the German salient was supported by 1,481 airplanes directed by Mitchell, totaling 24 Air Service, 58 French Aéronautique Militaire , and three Royal Air Force squadrons in coordinated operations. Observation and pursuit planes supported ground forces, while

9265-615: The other two-thirds of the aerial force bombed and strafed behind enemy lines. Later, during the Meuse-Argonne offensive , Mitchell employed a smaller concentration of airpower, nearly all American this time, to keep the German army on the defensive. Promptly after the armistice, the AEF formed the Third United States Army to march immediately into Germany, occupy the Coblenz area, and be prepared to resume combat if peace treaty negotiations failed. Three corps were formed from eight of

9374-513: The passage of the National Defense Act, June 4, 1920 (Public Law 66-242, 41 Stat . 759-88), the Air Service was statutorily recognized as a combatant arm of the line along with the Infantry , Cavalry , Field Artillery , Coast Artillery , Corps of Engineers , and Signal Corps , and given a permanent organization with a fixed complement of personnel. However this also legislated the form of

9483-512: The period of organizational training. The design must be submitted to the Chief of Air Service, AEF, for approval. The design should be simple enough to be recognizable from a distance." The first U.S. aviation squadron to reach France was the 1st Aero Squadron , which sailed from New York in August 1917 and arrived at Le Havre on September 3. A member of the squadron, Lt. Stephen W. Thompson , achieved

9592-509: The post-war Air Service was marked by a prolonged debate between adherents of airpower and the supporters of the traditional military services about the value of an independent Air Force. Airmen such as Brig. Gen. Billy Mitchell supported the independent air concept. The Army's senior leadership from World War I , the United States Navy , and the majority of the nation's political leadership favored integration of all military aviation into

9701-431: The post-war Air Service. In July 1918 the AEF organized its first wing formation, the 1st Pursuit Wing, made up of the 2d Pursuit, 3rd Pursuit, and 1st Day Bombardment Groups. Each army and corps echelon of the ground forces had a chief of air service designated to direct operations. The Air Service, First Army was activated August 26, 1918, marking the commencement of large scale coordinated U.S. air operations. Foulois

9810-454: The signing of the Treaty of Versailles on June 28, 1919, President Wilson relinquished his war powers under the Overman Act, and on July 11 Congress granted legislative authority to continue the Air Service as a temporary independent branch of the War Department for another year, easing fears of airmen that the Air Service would be demobilized out of existence. At the end of November 1918,

9919-533: The time or infrastructure in the United States to equip units to send overseas using aircraft designed and built in the U.S., the AEF Air Service acquired Allied aircraft designs already in service with the French and British air services. On August 30, 1917, the American and French governments agreed to a contract for the purchase of 1,500 Breguet 14 B.2 bombers-reconnaissance planes; 2,000 SPAD XIII and 1,500 Nieuport 28 pursuits for delivery by July 1, 1918. By

10028-548: The time the only division assigned to VI Corps. During the period 23 October through 9 November, the VI Corps sector was very quiet, and also the weather was very bad for flying. Nevertheless, the group took numerous aerial photographs of enemy territory, made daily visual reconnaissances and made several adjustments of artillery. It noted the enemy was forming artificial lakes at Cheminot and Mailly-sur-Seille , being formed by its engineers damning streams. A patrol on 10 November

10137-673: The units at the front on November 11, 1918, were approximately 11% of the total combat aircraft strength of the Allied forces. The 45 squadrons in the Zone of Advance had 767 pilots, 481 observers, and 23 aerial gunners, covering 137 kilometers of front from Pont-à-Mousson to Sedan . They flew more than 35,000 hours over the front lines. The Air Service conducted 150 bombing missions, the longest 160 miles behind German lines, and dropped 138 tons (125 kg) of bombs. Its squadrons had confirmed destruction of 756 German aircraft and 76 German balloons, creating 71 Air Service aces . Rickenbacker finished

10246-474: The various squadrons at Coblenz, especially those with a background in aeronautical engineering, along with the 12th flew these aircraft and evaluated their flight characteristics and tested them for performance for strengths and weaknesses. On 15 April 1919 the Third Air Service Squadrons at Coblenz were ordered demobilized, and the IV Corps Observation Group was ordered moved to Sinzig Aerodrome,

10355-496: The war as the leading American ace, with 26 aircraft destroyed. 35 balloon companies also deployed in France, 17 at the front and six en route to the Second Army, and made 1,642 combat ascensions totaling 3,111 hours of observation. 13 photographic sections were assigned to observation squadrons and made 18,000 aerial photographs. 43 flying training, air park (supply), depot (maintenance), and construction squadrons were located in

10464-412: Was activated on October 12 with Col. Frank P. Lahm as chief but was not ready for operations until just before the armistice. The Air Service, Third Army was created immediately after the armistice to provide aviation support to the army of occupation, primarily from veteran units transferred from the First Army Air Service. Despite their fractious relationship, Mitchell and Foulois were of one mind on

10573-565: Was appointed to the vacancy on January 2, 1919, but the patchwork nature of laws and executive orders that had created the various parts of the Air Service prevented him from exercising all their legal powers and ending the unity of command problems caused by dual authority. The United States began the World War with 65 pilots, a few of which were veterans of the Mexican Expedition , and some who were still in training. None were familiar with

10682-448: Was appointed to the vacant position of Second Assistant Secretary of War and designated as Director of Air Service, nominally in charge of the DMA. The Department of Justice report followed two months later and also blamed the delays on administrative and organizational deficiencies in the Aviation Section. Ryan's appointment came too late for any effective consolidation of both agencies, continuing an obstructive division of authority that

10791-411: Was formed for the purpose of operations in the forthcoming American offensives of First Army. Its units consisted of a Headquarters Squadron, the 135th Aero Squadron , arriving at Ourches on 30 July. A second squadron, the 8th Aero Squadron , was assigned to the group on 31 August. Both squadrons were assigned to the Group from the 1st Observation Group School at Amanty Aerodrome . The first efforts of

10900-514: Was held by Brig. Gen. Billy Mitchell). The primary missions of the Air Service were observation and pursuit aviation, and its tactical squadrons in the United States were controlled by the commanders of nine corps areas and three overseas departments created by the Act, primarily in support of the ground forces. The Chief of the Air Service retained command of training schools, depots, and support activities exempted from corps area control. The headquarters of

11009-410: Was made over enemy lines for reconnaissance of enemy infantry and artillery positions. A morning combat patrol was made on 11 November in which all group planes patrolled the lines in compliance with orders from Second Army headquarters. After the Armistice with Germany and the conclusion of the war, squadron flying continued on a limited basis to keep the pilots proficient in their skills. However,

11118-510: Was named Director of Air Service Instruction (DAI). Kenley proved to be only an interim commander, as Brig. Gen. Benjamin Foulois replaced him on 27 November 1917, arriving in France with a large but untrained staff of non-aviators. This resulted in considerable resentment from Mitchell's smaller staff already in place, many of whom in key positions, including Bolling, Dodd and Lt. Col. Edgar S. Gorrell , were immediately displaced. Mitchell, however,

11227-628: Was named chief of the First Army Air Service over Mitchell, who had been directing air operations as chief of the I Corps Air Service since March, but Foulois voluntarily relinquished his post to Mitchell and became the Assistant Chief of Air Service, Tours, to unsnarl delays in personnel, supply, and training. Mitchell went on to become a brigadier general and chief of the Army Group Air Service in mid-October 1918, succeeded at First Army by Col. Thomas Milling . The Air Service, Second Army

11336-476: Was never resolved during the war. Following the Armistice, Ryan resigned on November 27, leaving both the BAP and DMA, as well as the original Aircraft Board, leaderless. In addition certain powers, primarily those of dealing legally with the government-owned Spruce Production Corporation , had been delegated to Ryan by name, not to his position as Director of Aircraft Production, and as such could not be legally conferred on any successor. Maj. Gen. Charles Menoher

11445-550: Was not replaced and became a source of persistent discord with Foulois. Pershing restated the responsibilities of the Air Service AEF with G.O. No. 81, May 29, 1918, in which he replaced Foulois as Chief of Air Service AEF with a West Point classmate and non-aviator, Major General Mason Patrick . Air Service staff planning had been inefficient, with considerable internal dissension as well as conflict between its members and those of Pershing's General Staff. Aircraft and unit totals lagged far behind those promised in 1917. Officers in

11554-496: Was organized overseas in 1920 to administrate squadrons in the Philippines . In 1921, the three groups based within the United States were sequentially numbered one through three and assigned different combat roles. The fourth was inactivated. The next year the groups overseas were numbered four through six as "composite" groups. In 1922 plans were formulated for three more groups to flesh out the anticipated GHQ Air Force, but only one,

11663-529: Was ready to proceed with any project Pershing might require. Pershing's aviation officer, Major Townsend F. Dodd , first used the term "Air Service" in a memo to the chief of staff of the AEF on 20 June 1917. The term also appeared on July 5, 1917, in AEF General Order (G.O.) No. 8, in tables detailing staff organization and duties. Mitchell replaced Dodd on 30 June 1917, with the position renamed "Chief of Air Service" and its duties described. After Mitchell

11772-590: Was relieved from Second Army on 21 November 1918 and transferred to the new Third Army Air Service , which was assigned to the Third Army's march to the Rhine River and the Occupation of the Rhineland . The Group was re-organized with all of its Aero squadrons being transferred to the 2d Air Instructional Center at Tours Aerodrome on 24 November. The 12th Aero Squadron was assigned to the Group for duty in Germany on 21 November. On 20 November, Corps Headquarters began

11881-593: Was superseded in September by Kenly, he remained as ex officio chief through his influence on Kenly as Air Commander, Zone of the Advance (ACA). The Air Service, American Expeditionary Forces was formally created on 3 September 1917 by the publication of AEF G.O. No. 31 and remained in being until demobilized in 1919. Kenly, an artillery officer, had been a student the previous winter in the Field Officers Course at
