Fokker D.XIII

The Dutch fighter Fokker D.XIII was a development of the Fokker D.XI and emerged from the experiences with the Fokker D.VII from the First World War. It was designed by Fokker's technical director and designer Reinhold Platz.

From his predecessor D.XI the pattern differed mainly used by the Napier Lion engine instead of the less powerful Hispano -Suiza 8Fb. The first flight took place on 12 September 1924. On July 16, 1925 was a D.XIII more speed and weight records will be set. 50 aircraft of this type were built and deployed starting in 1925 on the secret German air base in the Soviet Lipetsk to train German, later also of Soviet fighter pilots. When the base was closed in 1933, the Red Army received the remaining approximately 30 copies. Only a D.XIII was transferred to Germany. The Soviet designation of this type was I-39 or I- LD.
