The Mikoyan-Gurevich MiG-9 (Russian: ?????? ? ??????? ???-9, USAF/DoD
designation: Type 1, NATO reporting name: Fargo) was the first turbojet fighter
developed by Mikoyan-Gurevich in the years immediately after World War II. It
used reverse-engineered German BMW 003 engines. Categorized as a
first-generation jet fighter, it was moderately successful, but suffered from
persistent problems with engine flameouts when firing its guns at high altitudes
due to gun gas ingestion. A number of different armament configurations were
tested, but nothing solved the problem. Several different engines were
evaluated, but none were flown as the prototype of the Mikoyan-Gurevich MiG-15
promised superior performance.
A total of 610 aircraft were built, including prototypes, and they entered
service in 1948 with the Soviet Air Forces. At least 372 were transferred to the
People's Liberation Army Air Force in 1950 to defend Chinese cities against air
raids by the Nationalist Chinese and train the Chinese pilots in jet operations.
The MiG-9 was quickly replaced by the MiG-15, and three are known to survive.
In February 1945, the Council of People's Commissars ordered the
Mikoyan-Gurevich (MiG) OKB to develop a single-seat jet fighter to be equipped
with two German BMW 003 engines. Intended to destroy bombers, the aircraft was
to be equipped with a single 57-millimeter (2.2 in) or 37-millimeter (1.5 in)
gun, plus two 23-millimeter (0.9 in) guns. A more detailed directive was issued
on 9 April setting out requirements that the aircraft should have a maximum
speed of 900 kilometers per hour (559 mph) at sea level and a speed of 910 km/h
(565 mph) at an altitude of 5,000 meters (16,400 ft). It should be able to climb
to that altitude in four minutes or less and it should have a maximum range of
820 kilometers (510 mi). Three prototypes were ordered to be ready for flight
tests by 15 March 1946.
The test pilots found the fighter easy and simple to fly. Defects noted during
testing were that the engines flamed out when firing the cannon at high
altitudes due to gun gas ingestion, no ejection seat was fitted, nor were air
brakes or a fire suppression system. The fuel tanks were not self-sealing and no
armor was provided for the pilot. Despite these drawbacks, the MiG-9 was ordered
into production at Factory No. 1 before the acceptance tests were completed as
the Soviet leadership believed that its shortcomings could be rectified during
production. A batch of 50 aircraft, 40 single-seat fighters and 10 two-seat
trainers, were ordered in late 1946 to participate in the 1947 May Day parade.
In recognition of their accomplishment Artem Mikoyan and Mikhail Gurevich were
awarded the Stalin Prize in 1947.

The MiG-9 was flown in Soviet service by fighter regiments in the 1st, 7th,
14th, 15th, and 16th Air Armies. These last two were based near Kaliningrad and
in East Germany respectively. In addition, the 177th Fighter Aviation Regiment
of the 303rd Aviation Division near Yaroslavl flew the aircraft in 1949.
Six divisions of MiG-9s, each with two regiments of 31 aircraft, were
duties. The 17th Guards Fighter Aviation Division (GIAD) defended Shenyang, the
20th Fighter Aviation Division (IAD) guarded Tangshan, and the 65th IAD
protected Guangzhou. The 144th IAD defended Shanghai, the 309th guarded
Gongzhuling and the 328th IAD protected Peking. These units later handed their
aircraft over to the 6th, 7th, 12th, 14th, 16th, and 17th Fighter Divisions of
the People's Liberation Army Air Force when their training was complete. The
Chinese considered sending their MiG-9s to Korea in 1951 under Soviet pressure,
but reconsidered when the PLAAF commanders reported that they believed that it
would be better to retrain MiG-9 pilots on MiG-15s.
