History

The Fokker S-14, also called ‘Machtrainer’, was designed and produced by Fokker. It was designed as one of the world’s first jet fighter training aircraft, apart from being the first Dutch jet aircraft. The prototype, marked K-1, first flew on 19 May 1951. Its first flight was flown by Fokker test pilot Gerben Sonderman.

The Royal Netherlands Air Force ordered 20 aircraft of the type. The KLu aircraft were equipped with a Rolls-Royce Derwent 8 engine where the prototype flew with a Rolls-Royce Derwent 5 engine. The first production aircraft first flew on 15 January 1955 and deliveries to the Jachtvliegschool (JVS) started mid-1955. The final S-14 Machtrainer was withdrawn from Dutch service on 5 September 1967.

The prototype was modified during 1958 and dubbed ‘Machtrainer Mk 2’. The Rolls-Royce Derwent was replaced by a Rolls-Royce Nene 3 engine. The aircraft was registered as PH-XIV on 24 October 1960. Fairchild was granted license production rights for the Fokker S-14 in 1952. The company was hoping to sell the type to the United States Air Force but failed to do so.

A possible order for 45 S-14 Machtrainers for the Brazilian Air Force was not effectuated after all. Components for 5 aircraft were produced by Fokker in the Netherlands and shipped to Brazil. Assembly however never took place. The production was therefore limited to the prototype and the 20 aircraft for the Royal Netherlands Air Force.

Versions

Only 1 version was built, called Fokker S-14 Machtrainer.
