The unique F.XX tri-motor PH AIZ Zilvermeeuw was the first and only Fokker commercial aircraft with a retractable undercarriage. The 12-passenger transport had an elliptical-section fuselage instead of the rectangular form of previous Fokker transports. The cantilever high wing was of wooden construction and the fuselage a steel-tube structure.
Power was provided by three Wright Cyclone R-1820-F radial engines, one mounted in the nose and the other two carried on strut assemblies under the wings, for a cruising speed of 270 kph. The main landing gear units retracted rearwards into the engine nacelles.
Named Zilvermeeuw (Silver Gull), it was flown for the first time in 1933 and handed over to KLM for operation on services from Amsterdam to London and Berlin.
It was later sold via Air Tropic to the Spanish Republican government and was used to maintain liaison between Madrid and Paris during 1937. Its ultimate fate is unknown.

The Fokker F.XVIII retained the same basic design with metal fuselage structure and a high-set cantilever wooden wing but had a number of detail design improvements compared with earlier Fokker tri-motors.
Five F.XVIIIs were built in 1932 and all were put into service on the route from Amsterdam to Batavia in the Dutch East Indies. On this route to the East four passengers were accommodated in the main cabin in seats which converted for sleeping; the cabin also provided accommodation for the wireless operator and the navigator.
Several notable flights were made by F.XVIIIs. Between 15 and 22 December 1934 PH-AIS Snip (Snipe), re-engined with Pratt & Whitney Wasp T1D1 radials, covered 10300km from Amsterdam to Curasao in a flight time of 55 hours 58 minutes carrying 100kg of mail.

The F-XVIII Pelikaan PH-AIP left Amsterdam on 18 December 1933 and reached Jakarta four days later.

The F.XVIIIs were withdrawn from the long-distance routes in 1935. PH-AIS was joined in the West Indies by PH-AIO Oriol and both remained in service until 1946. The Oriol was converted for military use during the war period and carried a defensive machine-gun.
Two F.XVIIIs were sold to the Czech national line CSA and operated the route from Prague to Berlin and Vienna, normally carrying 13 passengers. Another of the type was sold to a Palestine freight operator and the famous Pelikaan was bought in October 1936 by Air Tropic, a French company acting for the Spanish government, and it is believed that the Pelikaan ended its days on military liaison and transport duties during the Spanish Civil War.

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.

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.
