During testing, the company received a contract from the Spanish Republican government for 26 G.1 "export" versions with Pratt & Whitney engines. Despite receiving payment, the order was never fulfilled as the Dutch government embargoed the sale of military equipment to Spain. Finland was interested in the G.I but eventually bought
Bristol Blenheim light bombers. Besides the Dutch
Royal Netherlands Air Force (
Luchtvaartafdeeling Aviation Departement), several foreign air forces showed an interest in the G.I. as a fighter or dive-bomber. To test its potential as a dive-bomber, the G.1 prototype was fitted with hydraulic dive brakes under the wings. Flight tests revealed that the G.1 was capable of diving at over 644 km/h (400 mph) and had aerobatic capabilities. Swedish Air Force officer
Captain Björn Bjuggren tested the G.1 in over 20 dives and reported favourably on its effectiveness as a dive bomber. Orders for G.1 Wasp aircraft came from Spain (26 ordered) and Sweden (18), while the Mercury variant was ordered by Denmark (12) with a production license that was never used, and Sweden (72). Although Belgium, Finland, Turkey, Hungary and Switzerland showed interest, they never placed firm orders. The
Luchtvaartafdeeling ordered 36 G.I's with 541 kW (825 hp)
Bristol Mercury VIII engines, the standard engine used by the Dutch Air Force in the
Fokker D.XXI fighter, to equip two squadrons. Although reports are fragmentary and inaccurate as to the results, G.1 fighters were employed over Rotterdam and the Hague, contributing to the loss of 167 Ju 52s, scoring up to 14 confirmed aerial kills. The highest scoring G.1 pilot was Gerben Sonderman, with four victories.
Aftermath At the conclusion of hostilities, several G.Is were captured by the Germans, with the remainder of the Spanish order completed at the Fokker plant by mid-1941 for the G.1s to be assigned as fighter trainers for Bf 110 crews at
Wiener Neustadt. For the next two years,
Flugzeugführerschule (B) 8 flew the G.1 Wasp until attrition grounded the fleet. There are no surviving G.Is today, although a replica has been built and is on display at the Dutch
Nationaal Militair Museum (National Military Museum). ==Variants==
