The P-1 Hawk ( Curtiss Model 34 ) was a 1920s open- cockpit biplane fighter aircraft of the United States Army Air Corps . An earlier variant of the same aircraft had been designated PW-8 prior to 1925.
100-587: The Curtiss P-1 Hawk was the first US Army Air Service aircraft to be assigned the "P" (Pursuit) designation which replaced seven designations for pursuit aircraft, including "PW" (for "Pursuit, Water-cooled engine"). The P-1 was the production version of the Curtiss XPW-8B , an improved variant of the PW-8 , 25 of which were operational with the Air Service's 17th Pursuit Squadron In September 1923,

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

Refueling five times, he landed at Crissy Field , San Francisco, California, at 9:46 p.m., one minute before dusk, covering 2,670 mi (4,297 km) in 20 hours and 48 minutes. His flight time included four planned 30-minute stops at McCook Field , Ohio ; Saint Joseph, Missouri ; Cheyenne, Wyoming ; and Salduro Siding, Utah ; and an unplanned stop in North Platte, Nebraska for additional fuel when
500-538: 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

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

He also lost an hour at McCook to repair a broken fuel valve after an over-eager mechanic had over-torqued the valve, damaging it. The original fifteen P-1s served in the 27th and 94th Pursuit Squadrons, 1st Pursuit Group , Selfridge Field , Michigan . The first Hawk to serve with the Air Corps in quantity was the P-1A (17th, 27th, and 94th Pursuit Squadrons) beginning in 1925. In October 1928
800-515: 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 ,
900-904: 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

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.

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

The newest P-1 variants remained in operational service until 1930. The March 7, 1925 order for the P-1 also requested five aircraft with the more powerful 500 hp (373 kW) Curtiss V-1400 engine installed. These were completed in January 1926. The first (SN 25-420)

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

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

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

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

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

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

6800-537: 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
6900-485: 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
7000-992: 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
7100-743: The largest order of 33 P-1s was made. These were delivered by April 1929 as P-1Cs . The AT-4 and AT-5 trainer variants served with the 43rd Pursuit Squadron (School) at Kelly Field , Texas. While a total of 202 Hawks were built in the basic variants PW-8, P-1, P-2, P-3, P-5, AT-4 and AT-5, conversions resulted in 148 having a P-1 designation. All variants increased in weight with each succeeding model, resulting in slight reductions in performance with each.

7200-643: The line " of the United States Army with a major general in command. In France, 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
7300-723: 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
7400-629: 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
7500-952: The maximum ceiling of the P-1A, but their low-level performance was inferior Two single-seat advanced trainer variants were placed into production, the AT-4 and AT-5A , using Wright-Hisso E / Wright-Hisso V-720 V-8 engines. The resulting performance degradation from these lower powered engines resulted in them being deemed dangerous to fly, even for experienced pilots. All were re-engined with Curtiss D-12D engines and returned to use as fighters, designated P-1D and P-1F respectively. Five AT-4/XAT-5 test variants were re-classified as P-1E . A total of 202 PW-8, P-1, P-2, P-3, P-4, P-5, AT-4, and AT-5 airplanes were delivered. On June 23, 1924, taking off at 3:58 A.M., Army test pilot First Lieutenant Russell Maughan left Mitchel Field , New York, in PW-8 24-204, modified with additional fuel and oil tanks, made
7600-641: 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
7700-576: 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
7800-692: 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
7900-527: 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
8000-520: 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
8100-517: 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
8200-431: 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
8300-512: 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,
8400-540: 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
8500-677: 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
8600-502: 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
8700-487: 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
8800-522: Was an aircraft engine of 18.8 liter displacement . It was a water-cooled V12 , producing 443 hp (330 kW) and weighing 693 lb (314 kg). It was designed by Arthur Nutt in 1921 and used in the Curtiss CR-3 for the 1923 Schneider Trophy race. Fairey Aviation of England imported 50 Curtiss-built examples in 1926, renaming them the Fairey Felix . The D-12 was one of
8900-578: 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
9000-448: 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
9100-517: 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
9200-515: 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,
9300-580: 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
9400-476: 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
9500-550: 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
9600-502: 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,
9700-537: 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
9800-612: 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
9900-529: Was the last P-1A (serial 26-300). Originally intended to be powered by a 390 hp (291 kW) Curtiss R-1454, the engine was deemed unsatisfactory and the 410 hp (306 kW) Pratt & Whitney R-1340 engine substituted. A second XP-3A (serial 28-189) included a cowling and spinner to reduce the drag due to the radial engine; entered in the National Air Races of 1929, its speed of 186.84 mph (300.69 km/h) gave it second place in
10000-598: Was then modified with a turbocharger mounted on the right side of the fuselage nose, and whose turbine was driven by engine exhaust; the craft was designated XP-2 . However, the Curtiss V-1400 engine did not perform up to expectations, with or without the supercharger, and so after a year in service, three of the standard P-2 Hawks had their engines replaced with the Curtiss D-12 and were consequently redesignated as P-1s. The fifth machine (25-243) received
