MiG Alley
"MiG Alley" was the name given by United Nations pilots during the Korean War to the northwestern portion of North Korea, where the Yalu River empties into the Yellow Sea. It was the site of numerous dogfights between UN fighter pilots and their opponents from North Korea and the People's Republic of China. Soviet-built Mikoyan-Gurevich MiG-15 were the aircraft used during most of the conflict, and the area's nickname was derived from them. It was the site of the first large-scale jet-vs.-jet air battles, with the North American F-86 Sabre.
History
1950
The North Koreans began their war against South Korea on June 25, 1950, with small numbers of Soviet aircraft retained from the Second World War. These were flown by under-trained and inexperienced pilots. After the United States and its closest allies committed its air units to the UN, the North Korean People's Army Air Force was rapidly depleted. For several months, propeller-engined bombers and fighters, like the B-29 and P-51 Mustang – and early jet fighters like the F-80 Shooting Star, F-84 Thunderjet and Grumman F9F Panther – flew the skies over Korea virtually unopposed.During October, the major Communist powers – China and the Soviet Union – commenced unofficial military support of North Korea. The Soviets also committed to supply North Korea and China with its latest MiG-15 fighters, and to train Korean and Chinese pilots to fly them. China officially entered the war in support of North Korea on October 25, 1950. While its strength in ground forces initially overwhelmed UN forces, the Chinese People's Liberation Army Air Force was, at the time, small and no better equipped than the KPAAF.
While the Soviet Union never officially entered the war, on November 1, 1950, the 64th Fighter Aviation Corps of the Soviet Air Forces was attached to the PLAAF, under the 1st United Air Army. That same day, Soviet-piloted MiG-15s began operating over North Korea and the first clashes between MiG-15s and US aircraft occurred, when eight aircraft from the Soviet Air Forces intercepted about 15 United States Air Force P-51 Mustangs flying a ground support mission. First Lieutenant Fiodor V. Chizh shot down and killed Mustang pilot First Lieutenant Aaron Richard Abercrombie. Later in the day, the first air combat between jets occurred, when three MiG-15s attacked about 10 USAF F-80s. While First Lieutenant Frank L. Van Sickle Jr., in a F-80C, was killed, a US record states that he was shot down by AA fire. First Lieutenant Semyon F. Khominich – was credited with a kill by the Soviet authorities. On November 9, 1950, a MiG-15 was destroyed in combat for the first time, when Lieutenant Commander William T. Amen of the US Navy, in a F9F-2B Panther, shot down and killed Captain Mikhail F. Grachev.
In response to the deployment of MiG-15s, the UN's P-51 squadrons began to convert to jet fighters. In the case of the USAF, this was the F-86 Sabre.
UN Command standing orders forbade pilots from crossing the Chinese border. On December 17, Lieutenant Colonel Bruce H. Hinton led a finger-four formation of Sabres from the 336th Fighter Squadron on a patrol, a round trip, along the Yalu River, in an attempt to draw the MiG pilots into combat. The Sabre pilots stayed below, to create the impression on radar screens that the Sabres were a slower aircraft. The slower speed and two drop tanks on each F-86 also provided maximum air time. Forty minutes after take-off the Sabres were approaching the Yalu at. Four MiGs were spotted below the Sabres and about to pass beneath them. The Americans jettisoned their drop tanks and as the MiGs passed below, the Sabres turned to the left and dived down at the Soviet fighters. When the MiG pilots realized that their adversaries were not older jets that they could easily extend away from, they broke formation and headed for the border. Hinton caught up to the leader's wingman, Major Yakov Efromeenko, and fired 1,500 rounds of.50 caliber bullets. Smoke belched from its jet pipe and flames enveloped the tail section. After Efromeenko ejected, the MiG crashed about south of the Yalu.
On the morning of December 22, a Sabre was destroyed by a MiG-15 pilot for the first time. Captain Lawrence V. Bach's F-86 was hit in the wing root by cannon fire from an unknown MiG pilot and Bach was captured after ejecting. That afternoon, eight Sabres from the USAF 4th Fighter-Interceptor Wing, operating out of a forward base at K-14 Kimpo, attacked an estimated 15 MiGs at and pursued some to the Yalu, claiming six without loss.
1951–1953
On January 1, 1951, a Communist offensive drove UN forces out of the Kimpo area; K-14 was overrun and the 4th F-IW was withdrawn to Japan. In March 1951, the first two Sabre squadrons, from the 4th F-IW, returned to Korea, just in time to meet a new build-up of Communist air strength designed to secure air superiority over northwest Korea, in a prelude to a major ground offensive.While the Australian government had attempted to order the F-86, to replace Mustangs operated in Korea by No. 77 Squadron RAAF, North American was required to prioritize re-equipping the USAF. The British Gloster Meteor F.8 was the only viable alternative. 77 Squadron began converting to Meteors in Japan during April 1951.
USAF pilots nicknamed April 12, 1951 "Black Thursday", after 30 MiG-15s attacked 48 B-29 bombers escorted by approximately 100 F-80s and F-84s. The MiGs were fast enough to engage the B-29s and extend away from their escorts. Three B-29s were shot down and seven more were damaged, with no casualties on the communist side. Following this, USAF bomber sorties over Korea were halted for approximately three months. Bomber commanders were forced to discontinue daylight raids, and changed to night missions by small formations.
In the first five months of 1951 the 4th F-IW flew 3,550 sorties and claimed 22 victories. No F-86 Sabres were shot down by MiGs, although a number were lost due to accidents.
On July 10, 1951, truce talks between North Korean and UN representatives opened at Kaesong. The ground forces were virtually stalemated at the 38th parallel, but in the air the two squadrons of the 4th F-IW were flying the only Sabres in the theater. Some intelligence source estimated that 500 MiGs were being operated by the 1st United Air Army.
Although 77 Squadron RAAF had previously operated in Korea as a ground-attack unit, many of its pilots were veterans of World War II fighter units and it was expected that the Gloster Meteor would allow it to return to its previous role of interception. With 22 Meteors, 77 Squadron was attached to the USAF's 4th F-IW at Kimpo at the end of July. For a few weeks, MiG-15 pilots scrutinized the performance of the Meteors and used their superior speed to avoid engaging the Meteors. The first Meteor fatalities occurred on August 22, when two aircraft collided in mid-air as they returned to Kimpo after a sweep.
Meteor and MiG-15s pilots engaged each other for the first time on August 25, without either side scoring hits. Four days later, eight Meteors and 16 Sabres fought 12 MiGs; one Australian ejected after his aircraft was shot down, and a second Meteor was damaged. The following week, a Meteor suffered severe damage in a dogfight with MiGs. As a result of these losses, senior RAAF commanders decided to focus on escort and air defense sorties.
Flight Lieutenant R. L. "Smoky" Dawson registered No. 77 Squadron's first jet combat claim when he damaged a MiG during an escort mission near Anju, North Korea, on September 26, 1951. On October 27, Flying Officer Les Reading was credited with damaging another MiG while covering B-29s over Sinanju; it was subsequently confirmed as having been destroyed, making it the squadron's first MiG "kill". The squadron was awarded the Republic of Korea Presidential Unit Citation for "exceptionally meritorious service & heroism" on November 1.
On December 1, 1951, over Sunchon, at least 20 Soviet-piloted MiGs from the 176th Guards Fighter Air Regiment attacked a formation of 14 Meteors. Both sides apparently overestimated the scale of the battle and the damage inflicted to their opponents: while three Meteors were lost, Soviet pilots claimed nine Meteors destroyed; Australian pilots claimed one MiG shot down and another damaged, from a formation of at least forty MiGs, while Russian sources suggest that all of the MiGs returned to base and less than 25 MiGs were available to 176 GvIAP at the time.
The F-86As and F-86Es of the 4th F-IW were now getting decidedly battle-worn and it was decided that the 51st Fighter-Interceptor Wing was able to commence operations from Suwon on December 1 under Colonel Francis S. "Gabby" Gabreski. Nonetheless, the 4th F-IW claimed 13 MiGs in air battles on December 13.
On December 26, 1951, the RAAF reassigned 77 Squadron to ground attack sorties, a role it would pursue until the end of the war. Its pilots continued to encounter MiGs and claimed two more victories over them, both in the Pyongyang area, on 4 and May 8, 1952.
By August 1952, the tide of battle above "MIG Alley" had turned in favor of the United Nations. During that month 63 MiGs were shot down for the loss of only nine Sabres. An important reason for the increasing superiority of UN air power was the new F-86F, which had been issued to two squadrons of the 51st Wing in June and July and began reaching the 4th Wing in September. This Sabre development had a more powerful J47 engine developing thrust, wing shackles for drop tanks and a simplified A4 radar gun sight that was more efficient than the MkXVIII gyro sight used on most of the F-86As and easier to maintain than the rather unreliable A1CM radar sight fitted to late F-86As and Es.
One Meteor was shot down and another damaged by MiGs following a ground-attack mission on October 2, 1952. No. 77 Squadron was credited with downing its last MiG southeast of Pyongyang on March 27, 1953.
A special fighter-bomber variant of the F-86F arrived in Korea during January 1953 – the F-86-F-30 with dual stores mountings under each wing. This Sabre could carry either a drop tank or a bomb on the inner fittings, together with a drop tank on each of the outboard points. The new fighter-bombers were issued to the 18th Fighter Bomber Wing, which included 2 Squadron, South African Air Force. In February the 8th Fighter Bomber Wing began to replace its F-80s with Sabre fighter-bombers.
On July 27, 1953, the ceasefire came into effect. By that time there were 297 Sabres in Korea facing an estimated 950 Sino-Korean MiGs. During the conflict the F-86 pilots claimed to have destroyed 792 MiGs in air-to-air combat for a loss of 78 Sabres – a phenomenal 10 to 1 kills-to-losses ratio. In September the defection of a MiG-15 pilot enabled US pilots to assess their erstwhile opponent at first hand. The MiG that Lieutenant No Kum-sok flew into Kimpo on September 21 was one of the later MiG-15SDs.
More recent research by Dorr, Lake and Thompson however has claimed the actual ratio is closer to 2 to 1. The Soviets claimed to have downed over 600 Sabres, together with the Chinese claims. A recent RAND report made reference to "recent scholarship" of F-86 v MiG-15 combat over Korea and concluded that the actual kill:loss ratio for the F-86 was 1.8 to 1 overall, and likely closer to 1.3 to 1 against MiGs flown by Soviet pilots. However, this ratio does not include the number of aircraft of other types were shot down by MiG-15s. Overall, the US lost 1,986 aircraft during the Korean War, most conservative estimates put 250 of these due to air-to-air combat.
