In April 1924 the F.VII made its maiden flight. The F.VII and its derivatives were to revolutionise air transport. Slowly, but steadily, the F.III's capacity had become inadequate for the rapidly expanding air traffic, and KLM in particular was pushing for a larger successor. On December 10th, 1923, KLM signed a temporary contract for three F.VIIs, with an option on another three later on. The order would be confirmed if the prototype proved satisfactory during practical use. In 1924 the first F.VII went into service with KLM, the first, H-NACC, made the first flight from Amsterdam to Batavia, Java. Five in total were built in 1924-25.

After the Ford Reliability Tour Fokker made the F.VIIA/3m prototype available to the Army Air Corps for testing from Wright Field. After this military goodwill tour, the aircraft was flown to Detroit to be inspected by Edsel Ford, who purchased it. He then made the aircraft available to Lt Commander Richard Byrd, who used it to become the first to fly an aircraft over the North Pole on the 9th May 1926, naming the Fokker F.VIIa/3M Josephine Ford.

The first trans-Pacific crossing was in 1928 by the Fokker tri-motor “Southern Cross”. Unable to find afequate funding in theit own country, WW-1 Australian RAF pilots Charles E. Kingsford-Smith and C.T.P. Ulm, backed by Californian Capt. G. Allen Hancock, purchased a battered Fokker Detroiter without engines or instruments from Arctic explorer Sir George Hubert Wilkins. After modifications to strengthen fuselage and landing gear for extra fuel, and after obtaining Wright Whirlwind J-5C 200hp engine with US Navy help, now named “Southern Cross” they attemped to break the world endurance record in January 1928. “Smithy” and Lt. G.R. Pond flew for 50 hours, missing the record by two hours.
The Southern Cross left Oakland, California, on 31May 1928 headed for Australia. Crew were pilots Smithy and Ulm, navigator Harry W. Lyons, and radio operator James W. Warner. Oakland to Honolulu – 2408 miles, 27 hr 25 min; Hawaii to Suva, Fiji – 3144 miles, 34 hr 30 min; Fiji to Brisbane – 1795 miles, 21 hr 35 min. Total distance 7400 miles averaging 88.1 mph for 83 hr 15 min flying time, arriving at Brisbane on 9 June.
In 1929 Smithy and Ulm made a record flight from Australia to England. After overhaul at the Fokker factory in Amsterdam, the Southern Cross made an east to west Atlantic crossing in 31 hr 30 min in June 1930. The flight continued to Oakland, California becoming the first globe circling aircraft. It then pioneered air mail routes and barnstormed until retirement in 1935. It was refitted and flown in the late 1940s for filming the movie “Southern Cross”. It is now on display at Canberra National Museum, Australia.

Seven were built by Curtiss as RA-3. American military designation for the F.VIIB/3m was C-2.
The Fokker F.VIIb-3m one of two aircraft, both of which had crashed, and its wing had been united to the other aircraft, a single-engined F.VIIA. This hybrid had also crashed, and eventually the wing of the tri-motor, and the fuselages of both machines, had been shipped back to the Seattle Boeing factory, where the Tri-motor wing and fuselage were reunited, and the rear fuselage, fin and rudder redesigned to give greater stability. The reconditioned aircraft was re-designated Fokker F.VIIb-3m, and was sold, with Wright J4 engines and no instruments, to Kingsford-Smith, who eventually had it fitted with the later Wright Whirlwind J5 engines, and crossed the Pacific in it in June 1928, with Charles Ulm as co-pilot. The high cantilever thick-section wing consisted of two wooden box spars and plywood ribs, the whole being skinned with plywood. The fuselage and tail unit were welded steel-tube structures, covered mainly with fabric. Narrow chord ailerons were fitted to the main wing. The prototype Trimotor was used by Admiral Byrd on the first flight over the North Pole in May 1927.
Licence-production was also undertaken in Belgium, Italy, Poland and the UK (as the Avro Ten).
Approximately 184 were built. The F.VIIb-3m was also licence built as the Avro 618 Ten circa 1929.

The Avia F-VIIb /Fokker VII.B/3M monoplane was built under licence as the first transport plane from 1931. It was tested in the Scientific Aeronautical Institute as a bomber as the S-19, and as a transport by the Czechoslovak Air Liners Comp. Avia F-VIIb
