Preliminary translation
The idea to develop a training aircraft arose at Fokker shortly after the 2e world war .
The Tiger Moth biplanes used in the Netherlands for basic flight training date from the 1930s and were very outdated.
Partly because the Air Forces also renew their air fleet after the Second World War, there was interest in a new elementary training aircraft, also at the LSK. (LSK is the abbreviation of Air Forces, the name KLu did not exist yet)
After a number of preliminary designs, design no. 223 at Fokker eventually resulted in the Fokker S-11 Instructor, as the aircraft was officially called. The "S" was the traditional designation for training aircraft types at Fokker.
It would be a low-decker with a somewhat pre-war construction,
a hull of welded tubular steel, then partly clad in plywood and completely clad in linen, with an all-metal wing, vertical tail and horizontal stabilizer.
The direction and elevators mounted in the vertical tail and horizontal stabilizer were also covered with linen.
A buckled non-retractable landing gear was fitted under the wings and the cockpit seats would be side by side and not one behind the other, as was customary in a training aircraft until then.

FOKKER S.11 1947
After the war, Fokker's engineering office began work on a number of training aircraft projects, the first design being the F.25 Promoter being developed.
The S.11 "Instructor" was a trainer for the initial training; the seats were arranged next to each other, a way that Fokker had already tried to introduce in the early 1920s (SI, S.II).
The hull was of orthodox construction: steel tube and cloth covered. The wing was made entirely of light metal.
The air-cooled 190 hp Lycoming 0-435-A "flat-six" was chosen as the engine.
Avio-Diepen at Ypenburg, which is now part of the Fokker-VFW group, placed an order for one hundred aircraft of this type.
The Air Forces (later KLu) put 40 S.11s into service. 41 S.11s were supplied to the Israeli Defense Force for training and desert patrol. The Italian Aeronautica Macchi factory in Varese licensed this type and produced 150 aircraft, under the type designation Macchi 416.
Fokker, who had formed the Fokker Indtistria Aeronautica in Brazil, produced about a hundred S.11 aircraft for the Forgo. Area Brasileira.

The prototype of the S.11 is here on a test run before the start of the first flight.
Later, the cockpit hood at the rear would be extended.

This S.11 has made a demonstration tour through the USA.

The S.11 has flown for 22 years with the Royal Netherlands Air Force, here the E-13 in one of the last paintings.
Cn 6190 Reg. PH-NED
This S.11 was owned by a number of private owners until 1969.
The PH-NED has never flown with the Royal Netherlands Air Force.
An S.11 that has been in service with the Italian Air Force.
This S.11 was built under license by the Italian Macchi/IMAM with the type designation M-416.
Reg. 3105
This is an S.11.2, a modified version built for the Israeli Air Force.
Cn 001 Reg. 0705
The first S.11 built in Brazil at the Fokker Aeronautica factory in Rio.
At the Brazilian Air Force, the S.11 was given the type designation T-21.
Cn 6198 Reg. E-42
The S.11 here in front of the Aviodome at Schiphol has a fake registration.
An E-42 has never flown with the Royal Netherlands Air Force.
This S.11 has always been in the possession of private owners.
More than 70 years after the first flight of the Fokker S.11, a number are still flying.
Here the Fokker four team, who have been giving demonstrations with airworthy S.11s as an aerobatic formation for years.
