Fokker G-1 The Fokker G.I was a Dutch heavy twin-engined fighter plane comparable in size and role to the German Messerschmitt Bf 110 and the British Mosquito. Although in production prior to World War II, its combat introduction came at a time when the Netherlands was overrun. The few G.1s that were mustered into service were able to score some victories, but ultimately the aircraft was withdrawn from operations, and the remainder of the production run was taken over by the Luftwaffe as trainers. The G.I, given the nickname le Faucheur ("reaper" in French), was designed as a private venture in 1936 by Fokker chief engineer Dr. Schatzki. Intended for the role of jachtkruiser, "heavy" fighter or air cruiser, able to gain air superiority over the battlefield as well as being a bomber destroyer, the G.1 would fulfill a role seen as important at the time, by advocates of Giulio Douhet's theories on air power. The Fokker G.I utilized a twin-engined, twin-boom layout that featured a central nacelle housing two or three crew members (a pilot, radio operator/navigator/rear gunner or a bombardier) as well as a formidable armament of twin 23 mm (.91 in) Madsen cannon and a pair of 7.9 mm (.31 in) machine guns (later eight machine guns) in the nose and one in a rear turret. Besides its main mission, the G.1 could be configured for ground attack and light bombing missions (it could carry a bomb load of one 400 kg/882 lb bomb or combinations of two 200 kg/441 lb or 10 26 kg/57 lb bombs). The design and construction of the prototype (registered as X-2) was completed in just seven months. At its introduction at the Paris Air Show in November 1936, even before its first flight, the G.I was a sensation, appearing in a purple and yellow finish (evocative of the Spanish Republican colors, thought to be Fokker's first export customer Like all Fokker aircraft of the period, the G.I was of mixed construction; the front of the central pod and the tail booms were built around a welded frame, covered with aluminium plating. The back of the central pod, however, as well as the wings, had a wooden frame, covered with triplex, a technique also used in Fokker's successful passenger aircraft at that time. The G.I prototype, powered by 485 kW (650 hp) Hispano-Suiza 14AB-02/03 engines, had its first flight at Welschap Airfield, near Eindhoven on 16 March 1937 with Karel Toman-Mares at the controls. Later, Emil Meinecke took over much of the test flights. The maiden flight went well, but a subsequent test flight in September 1937 ended with a supercharger explosion that nearly caused the loss of the prototype.The accident prompted a replacement of the Hispano-Suiza engines with 559 kW (750 hp) Pratt & Whitney SB4-G Twin Wasp Junior engines.
