Fokker F.XXII

The prototype (PH-AJR) flew in early 1935 and was followed by two production machines, accommodating 22 passengers. All three were delivered to KLM, the prototype in March and the other two in May 1935. One aircraft crashed on 14 July 1935, but the other two operated European routes until they were sold in the UK, PH-AJR becoming G-AFXR in August 1939 on joining British American Air Services, and PH-AJP being re-registered G-AFZP in the following month when it was acquired by Scottish Aviation. Impressed for RAF service as HM159 and HM160 in October 1941, the two aircraft were used for transport and crew training. HM159 caught fire in the air and was lost in the Highlands, but HM160 was returned to Scottish Aviation post-war under its previous civil registration. It flew between Prestwick and Belfast for a time before being grounded finally at the end of 1947.
A fourth F.XXII was built for Swedish AB Aerotransport and delivered in March 1935. Named Lappland, it flew a regular schedule between Malmo and Amsterdam until destroyed in an accident at Malmo in June 1936.

Fokker F.XX

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.

Fokker F.XVIII

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.

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

T.IVA

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.
