The term Fokker Foe is a reference to the SPAD, a French biplane fighter aircraft used during World War I. The SPAD was designed by Louis Bechereau and first flew in 1913. It was one of the most successful fighters of the war, with over 8, 000 being produced. The Fokker Foe was a German fighter plane developed by Anthony Fokker in 1915. It was the first fighter plane to be equipped with synchronized machine guns, allowing it to fire through the arc of its propeller. The Fokker Foe was a formidable opponent for the SPAD, and the two planes were involved in many dogfights during the war.
