The three engined F.XIV/3m was the passenger carrying version of the F.XIV.

Fokker XLB 2 / C-2
The XLB 2 was a bomber developed by the American Fokker factory and based on the F.VIIBm, the military designation of which was C 2. The XLB 2 had two Pratt & Whitney Hornet radial engines of 525 h.p. each. An observer/bomb aimer, armed with a machine gun, was positioned in the nose.
Fokker C.VIII
The three seater C.VIII reconnaissance/bomber was the response to a request from the Aviation Department to make a larger reconnaissance aircraft than ever before.
The Dutch Naval Air Service purchased nine C.VIIIWs, which had three man crews.
Fokker C.VII
The C.VIIW seaplane was built for reconnaissance and advanced training. Fokker built 30, all of which were delivered to the Naval Air Service.
Fokker F.XII
In 1933 Fokker produced the F.XII, an airliner with three 420hp Wasp engines and accommodation for 16 passengers.
The prototype made its maiden flight at the beginning of 1930 and entered service on the KLM route to Batavia in March 1931. Ten more were built by Fokker, all for operation by KLM and its Far Eastern subsidiary KNILM, except for the final machine which was sold to Sweden and operated by AB Aerotransport as the Varmland.
The Dutch-operated F.XIIs maintained the routes to the Far East for two years, and were then switched to the European services connecting Amsterdam with London, Paris, Berlin and other principal cities. On the European runs the F.XIIs carried a crew of two and 16 passengers, but on the Far East route only four passengers were carried in a fair degree of comfort on fully reclining seats.
The Danish Orlogsvaerftet built two F.XIIs under licence for the national airline DDL to operate on the Copenhagen-Berlin route. The second, delivered in May 1935, was designated F.XIIM and had some aerodynamic refinements resulting in improved performance.
Six Dutch F.XIIs were later sold to British operators, and in turn four of the British machines were re-sold to the Spanish government, which had already bought the last KLM-operated aircraft. All were flown in the Spanish Civil War and were lost during the course of the conflict.
Last survivors were the Swedish aircraft and the Danish F.XIIM, the first scrapped in 1946 and the second a year later.

Fokker F.XI
The F.XI was a feeder liner and air taxi, and was similar to the American Universal in appearance. However, it was definitely not the same aircraft. The Universal was designed in America by Noordwyn; the F. XI in Holland. The aircraft could carry four to six passengers and two pilots. Three aircraft of this type were built, two going to the Hungarian Company Malert, and the third to the Swiss Company Alpar.

Fokker B.IV / F.XI.A
The original version of the B.IVA, the B. IV, also known as F.XI.A pure flying boat, only one was built.
The B.IVA amphibian flying boat had the wheel axles housed in stabilising floats which balanced the aircraft on water. During flight the wheels were retracted into recesses at the ends of the floats to reduce drag.
Twenty metal fuselages were constructed in Amsterdam, the B.IVA wings being made America. The B.IVA was the first Fokker flying boat to achieve any success, only one example of each of its predecessors having been made.
A number of these aircraft were sold, to companies as well as to individuals.
The PJ-1 flying boat developed from the B.4A.

Fokker T.IV
The T.IV, a large torpedo ¬bomber/scout on floats, was produced for the Naval Air Service in 1927.
From 1927 to 1941 12 T-IVs were in service with the Naval Air Service at home and in the Netherlands East Indies. Portugal also acquired three of these aircraft.
The T.IVA differed mainly in powerplant, having Wright Cyclone SR-1820-F2 radial engines in place of the T.IV’s 336kW Lorraine-Dietrich W-type engines. The more-powerful units required a strengthened airframe; at the same time an enclosed cockpit, as well as bow, dorsal and ventral gun positions, were installed. Twelve of these new aircraft were ordered for the Netherlands East Indies naval air force, and in 1936 the surviving T.IVs were brought up to T.IVA standard.
Coastal and sea reconnaissance operations in the Netherlands East Indies were still being flown when the Japanese invasion began in 1942, and the T.IVA was also used for air-sea rescue work, proving to be reliable and seaworthy.

Fokker F.IX / Avia F-IX
The F.IX, a 20 passenger airliner, two of which went into service KLM, was built under license in Czechoslovakia.
Though the Avia works produced some of Europe’s best fighters between the world wars, it was not judged economically feasible to attempt a heavy bomber. Accordingly, Avia, obtained a licence for the Fokker F.VII/3m, the pre-eminent civil transport of the 1920s, and while producing this for civil use also schemed a bomber version. The Czech army/air force, however, judged this aircraft too small. The upshot was a further licence for the Fokker F.IX, considerably bigger and weighing more than twice as much.
In 1932, Avia built 12 F.IX bombers, powered by three Walter Jupiter VII engines rated at 450 hp, carrying an internal bomb load of up to 1500 kg (3307 lb) and with any of a variety of armament schemes involving manually-aimed Vickers 7.92-mm (0.312-in) Mk 30 guns above and below the fuselage and firing from beam windows. Some aircraft had a retractable ventral ‘dustbin’.
The Avia F-IX was used only in a bomber version through the 30s until the March 15, 1939 German Occupation.
Jugoslavia bought two slightly modified aircraft designated F 39, powered by 560 hp Gnome-Rhone Jupiters, and obtained a sub-licence for this version.

Fokker F.VIII
Designed to meet a KLM (Royal Dutch Airlines) requirement for a larger aircraft than the F.VII single-engined series, the 12 15 seat Fokker F.VIII flew in prototype form on 12 March 1927. The nose contained a hinged baggage compartment, and the two 358kW Gnome-Rhone Jupiter VI engines were slung beneath the wings and a crew of two.
The prototype and six production F.VIIIs were delivered to KLM in 1927-28. One of them, PH-OTO, was later converted to have two engines positioned in the wing leading edge. Another was delivered to the Hungarian airline MALERT in 1928, and Manfred Weiss in Budapest built two more for MALERT under licence and were completed as bombers with two machine gun posts.
The KLM aircraft were subsequently re-engined, various aircraft being powered by 515kW Wright R-1820 Cyclone or 373kW Pratt ‘& Whitney Wasp engines.
The only F.VIII to see service in military markings was the last Dutch production aircraft, sold by KLM to British Airways in 1936. It went to Sweden in 1939, and was subsequently donated to the Finnish air force, with whom it served in the Continuation War from 1941.
