Russian Fokkers 4

In 1923, the Soviet Union purchased sixty Fokker C.IVs from the Netherlands. Their construction numbers were 2301 through 2360. They were designated C.IV Prima in Russia and had a long career, with the last one being retired in 1934. Although purchased as reconnaissance and light bombers, over the years an increasing number of C.IV Primas were transferred to the civil air fleet to perform other roles.

Training aircraft

In 1924, shortly after being received by the Red Air Force, eight C.IV Primas were assigned to the Higher Flying School in Moscow (also known as the 3rd Military Pilot School). Their armament was removed, the red stars disappeared from the wings, and a large white number was painted on the fuselage: 20 through 27. The construction numbers of these C.IVs are unknown.

Postal plane

In 1928, Dobrolet (the forerunner of Aeroflot) launched an experimental mail route from Moscow to Irkutsk. The route was 4,700 km long and divided into six segments, three of which had to be flown at night. Five C.IV Primas, temporarily loaned to Dobrolet by the Red Air Force, were allowed to test this route in 1928. This went well. In 1929, Dobrolet received 23 C.IV Primas from the air force for mail transport. They were given the civil registrations CCCP-150 through CCCP-172.
The mail planes were equipped with landing lights, navigation lights, and cockpit lighting, all powered by a wind generator and an auxiliary battery. The rear seat was converted into a cargo hold. It could carry 775 kg of mail, or 17 full mail bags.


Photo plane
On June 7, 1928, two Red Air Force C.IVs were transferred to Dobrolet for aerial cartography. A third C.IV was added later. The registration numbers of these aircraft were:
CCCP-174 c/n 2305
CCCP-173 c/n 2313
CCCP-167 c/n 2332 (originally a mail plane, see above)
They were given a camera installation on the floor of the rear seat.

The photographic and mail planes were stripped of their military equipment. The Liberty engine was replaced by an M-5, a Russian copy of the Liberty but with metric dimensions and tolerances (converted from inches to centimeters).
