Fokker S.IV


The Fokker S.IV was a military trainer aircraft produced in the Netherlands in the mid-1920s. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts, essentially a radial-engined development of the S.III. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with a cross-axle between the main units. The Royal [Netherlands Army Aviation Group] purchased 30 examples and used them right up to the German invasion of the Netherlands in 1940. On 14 May that year, a few surviving S.IVs escaped to France alongside some S.IX trainers, but never flew again.
The S.IV could be powered by a variety of engines in the range, including Siemens-Halske Sh 11, Le Rhône 9J, Bristol Lucifer, Armstrong-Siddeley Mongoose, Oberursel UR.II or the Clerget 9B.
