The 64th Fighter Aviation Corps (64th IAK) was an aviation corps of the Soviet Air Forces. The corps was the parent unit for Soviet interceptor units based in northeastern Manchuria during the Korean War.

The unit claimed a 3.4:1 kill ratio in favor of USSR pilots, destroying 1,097 enemy aircraft of all types during the war.

History 

The Korean War broke out in June 1950. On 11 October 1950,  Stalin agreed to send Mikoyan-Gurevich MiG-15 fighters of the Soviet Air Forces to provide air cover for the Chinese Communist People's Volunteer Army units then moving into North Korea. Tasked with providing air cover for bridges and for the hydroelectric power plants on the Yalu River, as well as for North Korean facilities and for the Chinese Communist rear area, 64th IAK pilots also trained Chinese Communist and North Korean pilots. On 1 November, Soviet MiG-15s began defensive patrols over the Yalu River. The 64th Fighter Aviation Corps, established on 14 November, comprised the 28th, 50th and 151st Guards Fighter Aviation Divisions. It was first commanded by Major General Ivan Belov. The Mig-15s of the 64th IAK began to clash with United Nations jet fighters, such as the North American F-86 Sabre.

On 1 November 1951, the 64th IAK became part of the People's Liberation Army Air Force's 1st United Air Army. In March 1952, the corps received new MiG-15bis aircraft. On 21 April 1952, pilots of the corps shot down two F-86s while losing six MiGs. On 4 July, the corps suffered its heaviest losses of the war when it lost 11 MiGs. During the Korean War, the corps flew 64,000 sorties and conducted 1,872 air battles. According to the  inflated official totals of the corps, 1,250 UN Forces aircraft were shot down, 1,100 by MiGs and 150 by antiaircraft artillery. The corps lost 335 aircraft, killing 120 pilots and 68 antiaircraft gunners.

The USSR claimed an overall kill ratio at 3.4:1 in favor of USSR pilots. Effectiveness of the Soviet fighters declined as the war progressed. While between november 1950 and January 1952 overall kill ratio was 7.9:1 in favor of the USSR, this declined 2.2:1 during 1952 and 1.9:1 in 1953. This was due in part to more advanced jet fighters appearing on the UN side and improving US tactics.

After the cease-fire of 27 July 1953, the corps withdrew from Korea. It moved to Petrozavodsk and became part of the 22nd Air Army. In  Karelia, the corps included the 26th, 216th and 336th Fighter Aviation Divisions. The corps disbanded in 1956.

Composition 
The composition of the corps constantly varied. During the war, the corps went through 12 fighter aviation divisions, two separate night fighter regiments, 2 Naval Aviation fighter wings, four antiaircraft artillery divisions and different rear units. The corps was composed of 26,000 personnel in 1952. On 1 November of the same year, 321 aircraft were in the combat units.

The participation of the Soviet Union in the Korean War was kept secret, and pilots were forbidden to approach the front line or fly over the sea. The aircraft used PLAAF markings and pilots were given Chinese Communist documents and uniforms. During the early actions, they were required to not speak Russian during missions and had to learn Korean phrases. After the first battles, the requirement was removed because it was practically impossible. The details of the Soviet participation in the Korean War were published in the Soviet Union only during the 1970s and 1980s. Despite all the secrecy, United Nations pilots were aware of the Soviet presence.

Each antiaircraft searchlight regiment had to equip 36 Radio RAP-150 stations. The regiment consisted of three searchlight battalion (4 searchlight companies to 12 stations). The searchlight platoon was equipped with RAP-2 150 and 2 3-15-3 Antiaircraft Searchlight Stations.  At the same time searchlight platoon stands out for night fighting maneuvering MSA batteries originally had a total of one station RAP-150 and three stations 3-15-4. The practice of combat work stations showed the unreasonableness of using RAP-150 when shooting at low-flying targets, as in mountainous terrain interference observed in the entire range of the station. In addition, the inability to adjust radar stations RAP-150 elevation with frequent change of position, lack of agility stations and the difficulty masking her forced to abandon the use of RAP-150 in mobile platoons. Radioprozhektornaya station RAP-150: mirror diameter of 150 cm, arc lamp, radiolocator, automatic tracking of the illuminated target. The brightness of the searchlight beam at a height of 5–7 km – 1,200 units or 1.5 million candles (for comparison – the brightness of the sun – 900 units).
