The S.II was designed as the second Fokker primary trainer, but unlike the earlier S.I monoplane the S.II was an unequal-span single-bay biplane with a fixed cross-axle landing gear.
It had side-by-side seating for an instructor and pupil and was originally powered by an 82 kW (110 hp) Thulin rotary engine.
The engine was later replaced with a Le Rhone-Oberursel engine.
