© Science Museum / Science & Society Picture Library
The Fokker E III Monoplane was designed for the German air forces by the Dutch aeroplane designer Anthony Fokker. The E III, or 'Eindecker' (one-wing) was a highly significant development in military aviation. Not only did it boast considerable aerial prowes, but it was also the first aircraft to be fitted with forward-firing machine-guns synchronised to fire between the rotating propeller blades.
