Fokker G.I
The Fokker G.I was a Dutch twin-engined heavy fighter aircraft from the late 1930`s.
The G.I was intended for the role of jachtkruiser, "heavy" fighter, able to gain air superiority over the battlefield as well as being a bomber destroyer.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.the G.I was of mixed construction; the front of the central pod were built around a welded frame, covered with aluminium plating. The back of the central pod, however, as well as the wings, were completely constructed with wood.
The G.I prototype, powered by 650 hp Hispano-Suiza 14AB-02/03 engines, had its first flight at Welschap Airfield, near Eindhoven on 16 March 1937.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 750 hp Pratt & Whitney SB4-G Twin Wasp Junior engines.
Flight tests revealed that the G.1 was capable of diving at over 400 mph and demonstrated aerobatic capabilities.Orders for G.1 Wasp aircraft came from Spain (26 ordered) and Sweden (18), while the Mercury variant was ordered by Denmark (12) together with a production license that never came to be used,[7] and Sweden (72). Although Belgium, Finland, Turkey, Hungary and Switzerland air forces showed great interest, they did not place firm orders.
The Dutch ordered 36 G.I's with 825 hp Bristol Mercury VIII engines, the standard engine used by the Dutch Air Force in the Fokker D.XXI fighter, in order to equip two squadrons. Only the first four examples were built as three-seaters intended for ground-attack, with the remainder being completed as two-seat fighters. During the lead-up to hostilities, a total of 26 G.I's were operational at Rotterdam (Waalhaven Airfield), and at Bergen near Alkmaar. The aircraft were actively involved in border patrols and in order to ensure neutrality.
On 10 May 1940, when Germany invaded the Netherlands, 23 G.1 aircraft were serviceable while production of Spain's order of the G.1 Wasp variant continued with a dozen aircraft completed, awaiting armament.
The German invasion started with an early morning Luftwaffe attack on the Dutch airfields. While the 4th JaVA received a devastating blow, losing all but one of its aircraft, eight 3rd JaVA G.1 fighters of the Waalhaven airbase in Rotterdam, that were already fully fuelled and armed, scrambled in time and successfully engaged several German aircraft. The surviving aircraft continued to fly, but with mounting losses, bringing their numbers down to three airworthy aircraft by the end of the first day.In the "Five-day War", the available G.1 fighters were mainly deployed in ground attack missions, strafing advancing German infantry units, but also used to attack Junkers Ju 52/3m transports.
There are no surviving G.Is today, although a replica has been built and is on display at the National Military Museum.
