In May 1940 the Fokker G-1 surely was the best plane the Dutch airforce could offer. Generally speaking in 1940 the Fokker G-1 was not bad plane but as soon would appear in combat with other fighter planes it was not a good match.

The G-1 in its time had a very progressive concept. This concept is now known as the multirole fighter. Basically a fighter which must be capable to perform all tasks but is not excellent at any task. (JSF Joint Strike Fighter / Tornado).

 

Quote from the  Fokker G-1 Mercury manual :

The Fokker G-1 is a 2- or 3-persons fighter, designed as two -engine cantilever mid-plane , suitable for different functions , such as :

  • GROUND ATTACK AIRCRAFT
  • WARPLANE/FIGHTER
  • BOMBER
  • DIVE BOMBER
  • RECONNAISANCE

 

The idea to develop this type of multi role fighter was an idea from Fokker himself, however the idea of a multi role machine was already known.

 

Around 1936 other aircraft manufacturers around the world developed aircraft with similar specifications.  The best known is the Messerschmit Bf 110 Zerstorer . This multifunctional idea lived in several countries , as is demonstrated by the strong interest and sales of licensed construction of the G-1 abroad. (Spain, Denmark , Sweden) Although the specifications for the G-1 Mercury were drawn up by the Air Force implementation was largely owned by Fokker. The requirement to serve as a reconnaisance-plane meant that the G-1 had to have a reasonable range, an observer and radioman to signal through the observations.The view had to be good hence the many windows in the hull (in practice the pilot proved to have the best view). The radio equipment at that time was quite heavy (69 kilos). All this together resulting in a rather large airplane. (hence likely to be called "G-1")

 

The pilot was obviously in the front, behind him between the main beams the radio operator, and in the shooting dome the observer / gunner / bombardier . The intention was that the G-1 was flown to a 3-man crew while observing and in other roles with a 2-man crew.
