The Fokker S.14 Machtrainer is a two-seater military training jet aircraft designed and manufactured by the Dutch aircraft manufacturer Fokker for the Royal Netherlands Air Force (RNLAF). It has the distinction of being one of the first dedicated jet-powered training aircraft to be produced in the world. The unarmed trainer served with Dutch Air Force for 12 years, and one prototype was used by the Dutch Aerospace labs for 6. Two were lost in air crashes, one in 1955 and a second in 1964. The Machtrainer features side-by-side seating with a single engine, although an under-belly gun pod and hardpoints were designed but not put into use.

Development started in the late 1940s at the behest of British engine manufacturer Rolls-Royce, who were seeking out a manufacturer to produce a new trainer aircraft powered by their Derwent turbojet engine. Fokker decided to design such an aircraft, designating it the S.14 Machtrainer. On 19 May 1951, the first prototype performed the type's maiden flight. Having secured an order from the RNLAF for 20 aircraft, the Machtrainer entered service with the service during 1955. It would be operated by the service until the last examples were retired in 1967. Several examples have survived to be on display in the 21st century.

Development

Origins

Following the end of the Second World War, the nations of Europe began to recover and rebuild their national industries, Dutch aircraft manufacturer Fokker was no exception. While initial activities revolved around the refurbishment and building of foreign-designed aircraft, such as the Hawker Sea Fury and Gloster Meteor, figures within the Dutch government and Fokker itself were keen to resume its own indigenous design activities as well. In particular, there was considerable interest in Fokker developing aircraft that would harness the newly available field of jet propulsion
