History

One of the first activities undertaken by Fokker after the second world war was the design of a new military aircraft for initial pilot training, the S-11 Instructor. An aircraft trader already placed orders for 100 of these aircraft in 1946, before construction had even begun. The first prototype flew at Schiphol on 18 December 1947. During testing in early 1948 it was found that some aerodynamic changes had to be made to improve the handling of the aircraft. Later that year demonstration flights for several air forces followed and eventually 101 S-11's were sold to the Royal Netherlands Air Force, Israeli Air Force, Italian Air Force and Brazilian Air Force. Numerous S-11 instructors are still flying today. The Dutch organization "Fokker Four" dedicated to the preservation of the aircraft owns five S-11's and amongst other activities still performs with them on airshows. The S-11 was also produced in Brazil by a Fokker subsidiary, which also manufactured a tricycle-undercarriage variant as the S-12
