The Curtiss-Wright Model 21 (also known as the Curtiss-Wright Model 21 Demonstrator, the Curtiss-Wright CW-21 Interceptor, the Curtiss-Wright CW-21 Demon) was an American fighter - interceptor developed by the St. Louis Airplane Division of Curtiss-Wright Corporation during the 1930s.
84-536: In 1938, George A. Page, head of the Saint Louis Airplane Division of Curtiss-Wright , decided to develop a fighter aircraft based on Carl W. Scott's two seater Model 19 . Page's concept was a lightweight fighter interceptor with as high a rate of climb as possible in order to allow bomber formations to be attacked with minimal warning. If faced with fighter opposition, it was intended not to dogfight, but to use its superior climb rate to escape. While this
168-721: A Fiat BR.20 bomber shot down on 4 April 1939. In May 1939, a contract was signed, with China receiving the prototype and three complete examples built by Curtiss, as well as kits for 27 more aircraft. Assembly would be undertaken by the Central Aircraft Manufacturing Company (CAMCO) at Loiwing, near the China-Burma border. These were to be armed with two .50 in (12.7 mm) and two .30 in (7.62 mm) machine guns. The three Curtiss-built aircraft were shipped to China in May 1940 and were eventually handed over to
252-745: A Norwegian training base established by the London-based government-in-exile. Still later, they were resold to the U.S. and redesignated the P-36G model. In 1943, the U.S. sent 28 Hawks to Peru under the Lend-Lease agreement. These were ex-Norwegian P-36Gs that had served in Canada. Portugal was officially neutral during World War II, although the Allies were allowed to use or establish ports and airfields on various Portuguese territories. One result of these friendly relations
336-523: A cost of $ 3 million. These simulators were unlike earlier ones produced in the late 1940s for airliners but now included visuals, sound, and movement. They were the first of today's modern flight simulators for commercial aircraft. In 1956, financially strapped automaker Studebaker-Packard Corporation entered into a management agreement with Curtiss-Wright to allow the nation's fifth-largest automobile manufacturer to avoid insolvency. The relationship lasted until 1959 at which time Curtiss-Wright withdrew from
420-578: A few exceptions. Throughout the 1930s, Curtiss-Wright designed and built aircraft for military, commercial, and private markets but it was the Wright engine division and the longstanding relationship with the U.S. military that helped the company through the difficult years of the Great Depression . Guy Vaughan was appointed president in 1935. In 1937, the company developed the P-36 fighter aircraft, resulting in

From mid-1940, some P-36s en route for France and the Netherlands were diverted to Allied air forces in other parts of the world. The Hawks ordered by the Netherlands were diverted to the Dutch East Indies and later saw action against Japanese forces. French orders were taken up by British Commonwealth air forces, and saw combat with
1260-610: The Hawk 75H —a simplified version with fixed landing gear, like the 75O—was eventually sold to the Chinese Nationalist government who presented it to Claire L. Chennault for personal use. China also received two similar demonstrators, the Hawk 75Q . They also used a number of simplified Hawk 75M s against the Japanese. On 11 January 1939, five Hawk 75Ms of the veteran CAF 25th Fighter Squadron led by commander Liu Yijun (劉依鈞) were flown to
1344-640: The Royal Air Force (RAF) and Royal Indian Air Force (RIAF). Axis and co-belligerent air forces also made significant use of captured P-36s. Following the fall of France and Norway in 1940, several dozen P-36s were seized by Germany and transferred to Finland; these aircraft saw extensive action with the Finnish Air Force against the Soviet Air Forces . The P-36 was also used by Vichy French air forces in several minor conflicts; in one of these,
1428-600: The Royal Netherlands East Indies Army Air Force (ML-KNIL), although some flew with 1-VlG V. These aircraft saw action over Malacca, Sumatra and Java, successfully bombing the railroad and intercepting bombers and participated in the extensive dogfights over Soerabaja, where USAAF, RAF and ML aircraft fought Japanese bombers and fighters together. Norway ordered 24 Twin Wasp-powered Hawk 75A-6s , of which 19 were delivered and seven assembled at

With around 1,000 aircraft built by Curtiss, the P-36 was a commercial success for the company. It also became the basis of the P-40 and two unsuccessful prototypes: the P-37 and the XP-42 . The Curtiss Model 75
1680-791: The United States Army Air Forces during World War II . It was the fighter used most extensively and successfully by the French Air Force during the Battle of France . The P-36 was also ordered by the governments of the Netherlands and Norway but did not arrive in time to see action before both were occupied by Nazi Germany. The type was also manufactured under license in China, for the Republic of China Air Force , as well as in British India , for
1764-627: The Wright J65 . It powered models of the Martin B-57 , and several U.S. fighter aircraft. Subsequent derivative engines were late and did not find substantial markets. Curtiss-Wright briefly licensed rights to the Wankel rotary engine from NSU in 1958 as a possible aircraft power plant. For this project, Curtiss-Wright relied on the design leadership of NSU-Wankel engineer Max Bentele . In 1954, United Airlines bought four Curtiss-Wright flight simulators at

But as the mainland surrendered, the aircraft continued to the colonies where they were used extensively against the Japanese attack on the Far Eastern part of the kingdom. By that time, the aircraft had flown so many hours that the engines were showing serious wear and tear. Most Dutch Hawks were assigned to the 1ste JachtVliegAfdeling - VliegtuigGroep IV (1ste JaVA - 1-VlG IV; "1st Fighter Squadron - Flying Group IV") of
2856-646: The P-36A entered production, the French Air Force entered negotiations with Curtiss for delivery of 300 aircraft. The negotiating process ended up being very drawn-out because the cost of the Curtiss fighters was double that of the French Morane-Saulnier M.S.406 and Bloch MB.150 , and the delivery schedule was deemed too slow. Since the USAAC was unhappy with the rate of domestic deliveries and believed that export aircraft would slow things down even more, it actively opposed

The Hawk was found to have lighter controls than the Spitfire at speeds over 300 mph (480 km/h), especially in diving attacks, and was easier to maneuver in a dogfight (thanks to the less sensitive elevator). The Hawk also had better all-around visibility and was easier to control on takeoff and landing. Not surprisingly, the Spitfire's superior acceleration and top speed ultimately gave it

Its first Mohawks were delivered to East Africa in mid-1941, where they were used by 3 Squadron SAAF to support operations in the East African Campaign , taking part in the Battle of Gondar which ended the campaign, and helping to patrol the border with Vichy French held Djibouti . These Mohawks were then sent to South Africa, where, supplemented by fresh deliveries, they were used for training and for home defense. The prototype of
5628-443: The very good flying characteristics of the fighter, and the armament was much more effective against Soviet aircraft. The Finnish Hawks were also equipped with Revi 3D or C/12D gunsight. Surviving Finnish aircraft remained in service with the FAF aviation units HLeLv 13 , HLeLv 11 and LeSK until 30 August 1948, when the last operational Finnish Hawks were put into storage. In 1953, the stored aircraft were scrapped. Even before
5712-423: The war, over 7,000 SB2C Helldivers . Its most visible success came with the P-40, variously known as the Tomahawk, Kittyhawk, and Warhawk, which were built between 1940 and 1944 at the main production facilities in Buffalo, New York . During the war, a second large plant was added at Buffalo, followed by new plants at Columbus, Ohio ; St. Louis, Missouri ; and Louisville, Kentucky . Engine and propeller production
5796-534: Was Lieutenant Edmond Marin la Meslée with 15 confirmed and five probable victories in the type. H75-equipped squadrons were evacuated to French North Africa before the Armistice to avoid capture by the Germans. While under the Vichy government , these units clashed with British aircraft during the Battle of Mers El-Kebir and the Battle of Dakar . During Operation Torch in North Africa, French H75s fought against U.S. Navy F4F Wildcats , losing 15 aircraft while shooting down seven American aircraft. From late 1942,
5880-444: Was a direct contradiction to the United States Army Air Corps ′ requirements for fighters (which stressed low-level performance), this did not concern Page, since the new fighter was intended for export. Detailed design of the new fighter, the Model 21, or CW-21, was carried out by a team led by chief engineer Willis Wells. It was a single-seat, all-metal cantilever low-wing monoplane with retractable tailwheel landing gear , where
5964-451: Was a private venture by the company, designed by former Northrop Aircraft Company engineer Don R. Berlin . The first prototype, constructed in 1934, featured all-metal construction with fabric-covered control surfaces, a Wright XR-1670-5 radial engine developing 900 hp (670 kW), and typical United States Army Air Corps (USAAC) armament of one .30 in (7.62 mm) and one .50 in (12.7 mm) machine gun firing through
6048-721: Was abandoned. However, Chinese license production of the Hawk 75A-5 was moved to India, and these aircraft were also absorbed into the RAF/RIAF as Mohawk IVs. They were supplemented by 10 Hawk 75A-9s that were captured in Iran, during the Anglo-Soviet invasion of Iran of August 1941. A further 74 Mohawk IVs that had originally been ordered by France were shipped to India from the United Kingdom. The only RAF units to see combat in Mohawks were No. 5 Squadron RAF and No. 155 Squadron RAF , using
6132-508: Was at plants in New Jersey, Pennsylvania, and Ohio. In May 1942, the U.S. government assigned Curtiss-Wright a defense production factory for wartime aircraft construction at Louisville, Kentucky , to produce C-76 Caravan cargo aircraft, which was constructed mostly of wood, a non-priority war material. After difficulties with the C-76, including a crash of a production model in mid-1943, as well as
6216-724: Was concerned about political turmoil in Europe, and about Seversky's ability to deliver P-35s in a timely manner, and therefore wanted a backup fighter. The Y1P-36 ( Model 75E ) was powered by a 900 hp Pratt & Whitney R-1830 -13 Twin Wasp engine, and the scalloped rear canopy was further enlarged. The new aircraft performed so well that it won the 1937 USAAC competition with an order for 210 P-36A fighters. The aircraft's extremely low wing loading of just 23.9 lb/ft gave it outstanding turning performance, and its high power-to-weight ratio of 0.186 hp/lb gave superb climbing performance for
6300-580: Was designated Model 75B with the R-1670 version retroactively designated Model 75D . The fly-off finally took place in April 1936. Unfortunately, the new engine failed to deliver its rated power and the aircraft only reached 285 mph (459 km/h). Although the competing Seversky P-35 also underperformed and was more expensive, it was still declared the winner and awarded a contract for 77 aircraft. However, on 16 June 1936, Curtiss received an order from USAAC for three prototypes designated Y1P-36 . The USAAC
6384-545: Was especially true in the first two years of the war. Curtiss' failure to research and develop more advanced wing and airframe designs provided an opening for North American , Bell , Lockheed, Northrop, and other U.S. aircraft manufacturers to win contracts from the Army and Navy for more advanced aircraft designs. The P-60 , the firm's last prop-driven fighter design, was merely an extrapolation of its 1930s P-36 Hawk , offering no advantage over other designs already in service. With
6468-590: Was headquartered in Buffalo, New York . With $ 75 million in capital (equivalent to $ 1.33 billion in 2023), it became the largest aviation company in the United States. By September 1929, Curtiss-Wright had acquired the Moth Aircraft Corporation (which primarily built de Havilland Moth aircraft under licence) and the Travel Air Manufacturing Company . There were three main divisions:
6552-532: Was later revealed that Wright company officials at Lockland had conspired with civilian technical advisers and Army inspection officers to approve substandard or defective aircraft engines for military use. Curtiss-Wright failed to make the transition to design and production of jet aircraft , despite several attempts. During the war, the company expended only small amounts on aircraft research and development, instead concentrating on incremental improvements in conventional aircraft already in wartime production. This
6636-706: Was marred by numerous teething problems with the engine exhaust, skin buckling over landing gear, and weak points in the airframe, severely restricting the performance envelope. By the time these issues were resolved, the P-36 was considered obsolete and was relegated to training units and overseas detachments at Albrook Field in the Panama Canal Zone , Elmendorf Field in Alaska , and Wheeler Field in Hawaii . The P-36s had been delivered to Hawaii in February 1941 by being loaded on
6720-453: Was not used in France), the aircraft were powered by Pratt & Whitney R-1830-SC-G engines of 900 hp and had instruments calibrated for the metric system, a seat for French dorsal parachutes, a French-style throttle which operated in reverse from U.S. and British aircraft (full throttle was to the rear rather than to the front) and armament of four (later models had six with two firing through
6804-626: Was part of "Groupe de Chasse II/5 La Fayette" (heir of the Escadrille Lafayette that fought in France during World War I), wearing the famous Sioux Head on its fuselage side. After the first few examples, aircraft were delivered in pieces and assembled in France by the Société Nationale de Constructions Aéronautiques du Centre . Officially designated as the Curtiss H75-C1 (the "Hawk" name
6888-410: Was provision for up to 10 30 lb (14 kg) bombs on underwing pylons. The last Argentinian Hawks remained in service until November 1954. In March 1942, 10 USAAC P-36As were transferred to Brazil. The Royal Air Force (RAF) also displayed interest in the aircraft. Comparison of a borrowed French Hawk 75A-2 with a Supermarine Spitfire Mk I revealed that the Hawk had several advantages over
6972-630: Was the transfer by the British government of 12 Hawk 75A variants to the Portuguese Air Force , or Força Aérea Portuguesa (FAP), which assigned them to air defense duties in the Azores . A few Hawk 75Ns were used by Thailand during the French-Thai War . They also fought at the Battle of Prachuab Khirikhan against Japanese forces during the Japanese Invasion of Thailand . On 28 January 1941,
7056-755: Was used extensively in the China-Burma-India Theater . From 1941 to 1943, the Curtiss Aeronautical plant in Lockland, Ohio , produced aircraft engines under wartime contract, destined for installation in U.S. Army Air Forces aircraft. Wright officials at Lockland insisted on high engine production levels, resulting in a significant percentage of engines that did not meet Army Air Forces (AAF) inspection standards. These defective engines were nevertheless approved by inspectors for shipment and installation in U.S. military aircraft. After investigation, it
