Fokker S.II
The Fokker S.II was a two‑seat trainer aircraft developed by the Dutch manufacturer Fokker in the early 1920s to address the post‑World War I demand for reliable primary trainers for both civil flying schools and military aviation units. First flown in 1921, the S.II was a low‑wing, single‑engine monoplane constructed of a mixed metal‑wood framework covered with fabric, a hallmark of Fokker’s lightweight design philosophy. Powered by a 90 hp (67 kW) Oberursel rotary engine, it offered a modest top speed of about 115 km/h (71 mph) and gentle handling characteristics that made it ideal for novice pilots learning basic flight controls, take‑offs and landings.
Key features included a straightforward, open‑cockpit arrangement with dual controls, staggered wings for improved visibility, and a fixed tailskid undercarriage that could operate from rough fields. The aircraft’s simplicity reduced maintenance costs, while its robust airframe tolerated the frequent training cycles of the era. Though only a few dozen were built, the S.II helped establish Fokker’s reputation for producing practical, economical trainers and influenced later designs such as the more powerful Fokker S.III. Its service with the Dutch Army Aviation and civilian clubs contributed to the standardisation of pilot training in Europe during the interwar period, marking the S.II as a modest yet significant stepping stone in aviation education.
