The Fokker D.XXI fighter was designed in 1935 by Dutch aircraft manufacturer Fokker in response to requirements laid out by the Royal Netherlands East Indies Army Air Force.
The Fokker C.X was a Dutch biplane scout and light bomber designed in 1933. It had a crew of two.
Fokker D.XVII, was a 1930s Dutch sesquiplane developed by Fokker. It was the last fabric-covered biplane fighter they developed in a lineage that extended back to the First World War Fokker D.VII.
Koolhoven F.K.52 was a Dutch-designed, two-seat reconnaissance-fighter biplane, which was developed in the 1930s by Koolhoven. The aircraft was equipped with an enclosed cockpit and single-strut landing gear. Only six aircraft were produced. The aircraft saw some service in the Finnish Air Force.
The Fokker Universal was the first aircraft built in the United States that was based on the designs of Dutch-born Anthony Fokker, who had designed aircraft for Germany during World War I. About half of the 44 Universals that were built between 1926 and 1931 in the United States were used in Canada. Among the famous pilots who flew the Fokker Universal were Punch Dickins and Walter Gilbert.
The Fokker F.IX was an airliner developed in the Netherlands in the late 1920s, intended to provide KLM with an aircraft suitable for regular services to the Dutch East Indies. When the onset of the Great Depression forced the postponement of those plans, the market for this aircraft disappeared as well, although it did see military service in Czechoslovakia as a bomber.
The Fokker T.IV was a Dutch torpedo bomber/maritime reconnaissance floatplane of the 1920s and 1930s. First flying in 1927, it served with the Dutch Naval Aviation Service in the Dutch East Indies until the remaining aircraft were destroyed during the Japanese invasion in 1942.
The Fokker C.VII-W was a reconnaissance seaplane built in the Netherlands in the late 1920s. Sharing elements of the highly successful C.V design, the C.VII-W was a conventional, single-bay biplane with wings of unequal span braced with N-struts. The undercarriage consisted of a standard twin-pontoon arrangement, and the fin and rudder continued through to the ventral side of the fuselage, creating a cruciform tail. The pilot and observer sat in tandem, open cockpits. The wing structure was wooden with fabric and plywood covering, and the fuselage was of steel tube construction with fabric covering.
The Fokker C.VIII was a reconnaissance aircraft built in the Netherlands in the late 1920s. Intended primarily for the photographic reconnaissance role, it was a larger machine than other Fokker reconnaissance types of the period, with space for a third crew member, who acted as camera operator. It was also Fokker's first aircraft of this type to be built as a monoplane, a parasol wing configuration. The construction, however, was in the familiar Fokker style with wooden wings covered with plywood and fabric, and a steel-tube fuselage, also fabric-covered.
The Fokker CXIV-W was a reconnaissance seaplane produced in the Netherlands in the 1930s. It was a conventional, single-bay biplane with staggered wings of unequal span braced by N-struts. The pilot and observer sat in tandem, open cockpits, and the undercarriage consisted of twin pontoons. 11 of the 24 examples produced were stationed in the Dutch East Indies. These were later joined by 12 aircraft that had escaped to the UK following the German invasion of the Netherlands in 1940. All C.XIVs were destroyed during the Japanese invasion of the Dutch East Indies.
The Fokker D.XIII was a fighter aircraft produced in the Netherlands in the mid-1920s. It was a development of the Fokker D.XI with a new powerplant and considerably refined aerodynamics, and had been designed to meet the requirements of the clandestine flying school operated by the German Army at Lipetsk in the Soviet Union. Like its predecessor, it was a conventional single-bay sesquiplane with staggered wings braced by V-struts. The pilot sat in an open cockpit and the undercarriage was of fixed, tailskid type. The wings were made of wood and skinned with plywood, and the fuselage was built up of welded steel tube with fabric covering.
The Fokker D.XVI was a sesquiplane fighter aircraft developed in the Netherlands in the late 1920s.
The Fokker DC.I was an aircraft produced in the Netherlands in the early 1920s to fulfill a role of combined fighter and reconnaissance aircraft. The company designation chosen by Fokker, "DC" reflected this, with "D" being the Idflieg designation for a fighter during World War I, and "C" being an armed reconnaissance aircraft. The DC.I was a conventional single-bay biplane with staggered, unequal-span wings braced by N-struts and was derived from the Fokker C.IV design. The pilot and observer sat in tandem, open cockpits, and the undercarriage was of fixed, tailskid configuration, with the main units linked by a cross-axle. The wings were of wooden construction, and the fuselage was of welded steel tube covered in fabric.
The Fokker S.IV was a military trainer aircraft produced in the Netherlands in the mid-1920s. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts, essentially a radial-engined development of the S.III. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with a cross-axle between the main units. The Royal Netherlands Army Aviation Group purchased 30 examples and used them right up to the German invasion of the Netherlands in 1940. On 14 May that year, a few surviving S.IVs escaped to France alongside some S.IX trainers, but never flew again.
The Fokker S.IX was a military trainer aircraft produced in the Netherlands in the mid-1930s, designed at a Royal Netherlands Navy request for a machine to replace the obsolete Fokker S.IIIs then in service. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with divided main units. The wing had a wooden structure, the fuselage one of welded steel tube, and the entire aircraft was fabric-covered.
The Fokker D.XXIII was a Dutch single-seat fighter designed and built by Fokker. Only one aircraft was flown before the country was invaded by the Germans in May 1940.
The Caproni Ca.335 Maestrale (Mistral) was an Italian single-engined two-seat fighter-bomber/reconnaissance aircraft of the 1930s.
The Fokker T.IX was a Dutch twin-engined bomber designed and built by Fokker for the Royal Netherlands East Indies Army Air Force as a replacement for their obsolescent Martin-built bombers.
The Fokker D.XII was a Dutch single seat, single engine fighter aircraft designed to an American specification which called for the use of a Curtiss D-12 engine, designated PW-7. Despite considerable efforts to improve the airframe, Fokker failed to win the USAAS competition.
The IIL IS-8 was a two-seat sailplane designed by Iosif Șilimon and built in Romania in 1960. They served with Romanian gliding clubs.
