The Fokker D.XIII was a fighter aircraft produced in the Netherlands in the mid-1920s.
It was a development of the Fokker D.XI with a new powerplant and considerably refined aerodynamics, and had been designed to meet the requirements of the clandestine flying school operated by the German Army at Lipetsk in the Soviet Union.
Like its predecessor, it was a conventional single-bay sesquiplane with staggered wings braced by V-struts.
The pilot sat in an open cockpit and the undercarriage was of fixed, tailskid type.
The wings were made of wood and skinned with plywood, and the fuselage was built up of welded steel tube with fabric covering.
