All aircraft sold abroad. In April 1935, one F11C-3 sold in Turkey. In August, we began to supply 24 aircraft to Thailand (Siam). Next year ten fighters bought by Argentina.

The greatest number of Hawk III has purchased China — there, since 1936, was delivered of 102 aircraft. Almost all Chinese Hawk III has arrived in a disassembled state and assembled by local workers in aviamaster.
On 14 August 1937 the Chinese Hawk III engaged in battle with Japanese planes. Chinese pilots fought bravely against superior 13 times enemy forces and successfully led interceptions of the bombers. For example, in the first day of the war they managed to shoot down three bombers MITSUBISHI Tip 96 (G3M2). However, please note that these bombers flew without fighter cover, and their tanks were nepaterizovanny.
But at a meeting in the air with Japanese fighters the chances of the HAWK III was small, and not only because of the numerical superiority of the Japanese. Their main fighter — NAKAJIMA Tip 95 (A4N1) was nearly one ton lighter, and the engine was 30 HP more powerful than the American motor WRIGHT. Just a couple of months, the Japanese won air superiority, and after the fighter-monoplanes А5М destroyed almost all Chinese aircraft.
The government of Chiang Kai-shek appealed for aid to the Soviet Union In October 1937 in China began to receive the first Soviet fighters: I-16, I-15 and I-153. All the remaining HAWK III fighters and other older planes American, Italian and French production moved into the category of training machines. They occasionally continued to take part in the fighting, and by 1941 had been destroyed. Total built 139 fighters F11C-3.
The plane was a single-seat carrier-based fighter-bomber of mixed construction with retractable landing gear. The fuselage is functionally divided into three parts: the front (bow), medium (Central) and tail. Truss fuselage structure typical of all the previous fighters of the firm. The farm was a welded construction of steel pipes. For forming the longitudinal Central and rear fuselage were used dural l-shaped stringers.
In the front part of the fuselage on Motorama the engine was installed with the devices and assemblies fuel and oil systems. The engine has closed dural quick release hood type NACA. Between the cockpit and the engine are the oil tank, two fuel tanks, a niche cleaning the main landing gear and machine guns with ammunition boxes.
The mechanism of cleaning and landing gear were fixed on the power frame. From below in the mounting area of the chassis, the fuselage had a Central recess with holders outboard fuel tank or 227-kg bombs. The forward fuselage was closed with a quick-detachable duralumin panels, providing convenient access to machine guns, oil and fuel tanks, the mechanism to retract the main landing gear.
The cockpit is semi-enclosed type located in the Central part of the fuselage. Front pilot covered visor consisting of three rectangular Plexiglas panels. Before the visor on two uprights were fixed telescopic sight. Side of the pilot’s head was covered by a lantern, dvigausciesya if necessary ago. The pilot seat, height adjustable, consisted of two profiled aluminum parts. Headrest seats have soft, covered with leather cushion. Reservation was missing.
Instrumentation housed on the Central fascia panels and on the Central bottom panel, a so-called “beard”. Part of controls and equipment (e.g. lever engine control, wheel rudder stabilizer) were placed on the sides of the cab. Trim middle part of the fuselage fabric.
Immediately behind the cockpit, started the aft fuselage. The upper part formed a fairing — fairing headrest of the pilot, closed dural panels. Under the removable panel of the fairing was laid rescue equipment — inflatable rubber raft, a supply of food and drinking water, and flares. At the bottom of the outside compartment installed in the power station; for its service in the left side of the fuselage was provided with rectangular quick-release hatch.
To the rear of the fuselage is attached to the stabilizer and fin with rudders and height, and front tail spike wheels.
The wing of the plane made by the scheme biplane, and has all-metal construction. The upper wing consists of a center section and consoles. Power set of the wing is formed by two spars and set of ribs. Dural spars, box-type. The ribs are also made of metal. Wing tip in special sockets fit the ballonets bags made of rubberized fabric to ensure the buoyancy of the aircraft when making a forced landing on the water. Filling the ballonets with compressed air produced by the pilot with the valve located to the right of his chair. In the center section of the upper wing at the trailing edge was cut to improve visibility of the upper hemisphere.
The lower wing consisted of the left and right consoles and in construction differed little from the top. Each console lower wing is positioned in the two holders for a 45-kg bombs. The upper and lower wings were connected by two N-shaped struts. The same under-braids-struts, the upper wing attached to the fuselage. On the right wing strut was fixed to the receiver air pressure (LDPE) pointer speed flight.
Brace-wing — steel cable, doubled. The ailerons are located only on the upper wing. Control ailerons hard, through the rod pushrods going to the ailerons from the lower wing. The wing skin fabric. The ailerons of the wing had a duralumin skin.
Tailplane composite construction. Power set, consisting of spars and ribs, is made of aluminium alloy. Covering all surfaces of the tail plain. The rudder horn is made with aerodynamic compensation. Trimmers were installed on both the rudder and the elevators. The design of the stabilizer was provided the opportunity to change angle installation screw mechanism. To ensure the necessary rigidity of the stabilizer and fin are contracts between a cable braces. Control the control surfaces of the cable.
The power plant of the aircraft includes desyatitsentovoy the engine of air cooling WRIGHT R-1820-04 CYCLONE. On most aircraft the exhaust manifold is missing. Each cylinder is equipped with an individual exhaust pipe, diverting the exhaust from the fuselage in a free stream. Engine management is done by the control lever engine (ORE), mounted on the left side of the cockpit. Manned aircraft two-blade metal variable-pitch propellers Hamilton STANDARD company.
Fuel contained in two fuselage nepaterizovanny fuel tanks with a total capacity of 418 liters. Front lower 209-liter was placed immediately behind the power frame and niches of cleaning the main landing gear struts. Rear upper the same capacity (209 liters) was located just above the front. Among themselves they were not connected and had separate filler. Development of fuel is carried out alternately from the transferee and rear tanks. Placing them near the center of gravity does not violate the alignment of the aircraft and did not affect its handling. At the bottom of the fuselage it was possible to install additional overhead 189-litre tank. For engine oil system tank capacity 34 l is mounted directly behind the engine, before fuel tanks.
The chassis is retractable, with the tail spike wheel. Stand the main chassis of the pyramidal type with oil-air shock absorbers. The system of harvesting and the landing gear is typical of the first American aircraft with retractable landing gear the first half of the thirties. Cleaning was carried out by retraction of the landing gear inside the fuselage by means of a chain transmission driven by a knob on the left side of the cockpit. When the wheels are placed in special niches on the side panels of the fuselage. Stands were fixed on the strengthened power of the frames, simultaneously performing as a fire wall. Main wheels were equipped with air drum brakes. Stand freely oriented tail wheel had a rubber cushioning.
The armament of the aircraft consisted of bomber and missile. The latter was represented by two synchronized fuselage 7.62-mm machine guns COLT-BROWNING with ammunition at 600 rounds per gun. Four bomb racks were placed small bombs caliber or 45,3 52,6 kg. In the Central ventral node of the suspension can be suspended for one 227-kg bomb.
