S.14 Machtrainer

The Fokker S.14 Machtrainer was a pioneering Dutch jet trainer that entered service in the late 1950s. Designed by Fokker as its first indigenous jet aircraft, the Machtrainer first flew on 23 May 1955, powered by a single Rolls‑Royce Derwent V turbojet delivering around 3,500 lbf of thrust. Its all‑metal low‑wing monoplane layout featured a tandem cockpit with fully glazed canopies, providing excellent visibility for both instructor and student. The aircraft’s relatively simple hydraulic and electrical systems, combined with forgiving handling characteristics, made it an ideal platform for transitioning pilots from piston‑engine trainers to frontline jet fighters. A total of 145 units were produced, most serving with the Royal Netherlands Air Force, which used the type until 1980, and a few were exported to countries such as Italy and Belgium. The Machtrainer’s significance lies in its role as a bridge between propeller‑driven trainers and modern supersonic jet trainers, influencing later designs like the Fouga Magister and shaping NATO jet‑training doctrine during the early Cold War era. Its reliable performance and economical operation cemented Fokker’s reputation in military aviation. The aircraft also served as a testbed for aerodynamic research, contributing data that benefited subsequent European jet programs.
