Korean War: The Boeing B-29 Superfortress Served Throughout the Air War

Military History  | 2 comments  | Print This Post  | Email This Post

As the replacement crews arrived and became combat qualified, veteran crews were shipped home, although there was one exception. General MacArthur retained five atomic bomb­qualified B-29 bomber crews within the combat zone so that, if the war escalated, U.S. forces could respond with nuclear weapons. President Truman and his military and foreign-policy advisers, however, were firmly committed to keeping the war limited because they were more concerned with a potential Soviet armed incursion into Western Europe. It would have been unrealistic for MacArthur to initiate a widened ground offensive or launch airstrikes north of the Yalu River, but just in case, the five atomic bomb­qualified crews alternated on 10-day ground alert and 10-day off status. The retained crews also served as combat instructors for newly arrived replacement aircrews. Even though atomic bombs were never used in the Korean War, MacArthur’s contingency plans provided grist for speculation about what might have happened if they had been used.

When U.N. troops retreated from North Korea, FEAF aircrews were called upon to provide tactical interdiction. Using conventional bombs, the aircrews greatly delayed the southward advance of the Chinese Fourth Field Army, giving the U.S. Eighth Army time to prepare defenses. The FEAF inflicted an estimated 40,000 causalities on the advancing Chinese, decimating a force equivalent to five divisions.

Although B-29 atomic-qualified crews had demonstrated their ability to attack fixed positions (permanent strategic targets), there was still some reason to believe that the U.N. command forces were not well enough prepared to use atomic weapons effectively against moving ground troops (tactical targets). In any case, U.S. Intelligence did not identify hostile concentrations at Taechon and in the Iron Triangle in November 1950 until they were breaking up. And atomic attacks against Imjin and Wonju would have been close enough to U.N. troop elements to cause casualties.

The threat of using atomic weapons, however, did help to end the war. On May 22, 1953, U.S. Secretary of State John Dulles sent a message to the Chinese leadership via the Indian diplomatic corps. The Chinese were raising unnecessary barriers to an armistice agreement ending the Korean War, said Dulles, and if peace was not forthcoming, the United States would bring in atomic weapons. Within 11 days, the Chinese accepted the armistice plan, with minor changes.

By January 1951, it was necessary to restrict B-29 operations to steer clear of ‘MiG Alley’–the area between the Chongchon and Yalu rivers where MiG-15s based in the Antung complex in Manchuria constituted a particular threat. B-29s were withdrawn after Chinese troops captured the U.S. Air Force fighter airfields at Kimpo and Suwon, compelling the Americans to withdraw their North American F-86 Sabres to air bases in Japan. Since the B-29s were highly vulnerable to MiG attack, they required supporting fighters.

Nevertheless, the B-29s continued to pound other Communist targets with effective results. During November 1952, B-29s attacked three airfields that the Chinese were trying to build at the southern end of MiG Alley, north of the Chongchon River. Repeated B-29 attacks forced the Chinese engineers to stop work on those three airfields, as well as their attempts to repair previously damaged airfields.

In order to keep up such devastating attacks, the B-29s required extensive post-mission maintenance to make their three-day turnaround times. Post-mission maintenance consisted of inspecting the bomber’s engines and skin for flak damage, washing dirt and oil off the aircraft to maintain maximum aircraft speed, tightening oil connections and any loose equipment, and checking oil sump plugs for metallic shavings, the presence of which indicated the onset of engine wear and probable future engine failure. Maintenance personnel also had to clear bomber crew post-mission write-ups and then complete engine tests to monitor correct operational limits. B-29s needed 7,000 gallons of aviation fuel, and oil reservoir tanks and lines had to be topped off prior to the next mission.

Weather was an important factor in the aircraft mechanics’ work–Korea tended to be mild in the fall and spring, bitterly cold in the winter and oppressively hot in the summer. Typhoons were a severe threat to the B-29 bombers on Okinawa. One typhoon warning forced an evacuation of the B-29s and supporting aircraft to Andersen Air Force Base on Guam. The majority of the ground personnel remained behind and waited out the storm. When the B-29s returned, maintenance personnel identified critical fuel-feed problems in the engines. The higher octane fuel used on Guam was eating into the seals of engine fuel-pump gaskets and causing them to leak. The B-29 fuel tanks had to be drained and the fuel-pump gaskets changed prior to the bombers being certified for the next mission.

During another typhoon alert, the winds were determined to be within the B-29’s structural tolerance, so the bombers were not evacuated to Guam. The B-29s were lined up on the runway, and the crews and maintenance climbed on board to ride out the storm. Sandbags were piled to wing level around one landing gear, while hydraulic lines were disconnected from the brakes on the other landing gear to let the bombers swing into the changing wind. The force of the winds, which reached 91 mph, caused the B-29’s propellers to turn. The crews reported it was an awesome experience, and the damage to the base was approximately $1 million. The next evening, the B-29s were ready to strike North Korean targets. Riding out the storm saved maintenance personnel three to six days of work.

Regardless of careful mission planning, fighter protection and night bombing attacks, B-29 aircrews operated in a dangerous environment. Communist anti-aircraft gunners and MiGs unloaded their vengeance on the B-29s. After the war, U.S. Intelligence studies indicated that the Communists’ inexperience in aerial warfare prevented them from making the most of their fighter force. F-86 pilots believed that most of the experienced pilots they encountered were probably from the Soviet Union or Eastern bloc countries, while the newer pilots were Chinese and North Korean. With the end of the Cold War, Air Force Intelligence was able to use Soviet records to confirm that many MiGs encountered by U.S. pilots in MiG Alley and officially reported to be Chinese and North Korean were, in fact, flown by Russian and Polish pilots. Those pilots were rotated through Chinese fighter squadrons for six weeks to gain practical combat experience against U.S. pilots. The Soviet involvement was heavily classified, but early in the war Soviet pilots were heard on radio during combat engagements. Some Soviet pilots were shot down, but the exact number has never been officially confirmed by either U.S. or Soviet air force records.

On January 10, 1953, one B-29 from the 307th BG was badly damaged by a MiG. The aircraft commander kept the bomber flying straight and level so that the crew could bail out. He stayed with the damaged bomber too long, however, and was unable to bail out. (The commander was posthumously awarded the Silver Star for saving the crew.) When the B-29’s left gunner reached the ground, a compassionate North Korean farm woman took care of his wounds before North Korean troops captured him. The gunner was then placed in solitary prison confinement until early May 1953. At that time, with about 10 or 12 other captured B-29 crewmen, he was transported to a larger prisoner of war (POW) camp.

The downed radar operator had also been quickly captured and spent three months in solitary confinement. Since he was an officer, the North Koreans made an exceptional effort to play mind games with him. At one point, he was dragged in front of a firing squad in the compound’s center courtyard. A North Korean officer barked a command, the soldiers raised their rifles at him and then held that position for several minutes. Of course, the radar officer thought he was about to be killed–as many downed crewmen were. Unexpectedly, however, the North Korean officer barked another command that made the soldiers lower their rifles and laugh at the badly shaken American officer. The radar officer was then dragged back to his cell.

American airmen suffered greatly while in Communist captivity. The food was bad and medical care practically nonexistent. Captured B-29 crewmen were usually held in isolated or solitary confinement for approximately three months and were fed two cups of rice a day. The prisoners wore the clothing they had on when captured, regardless of the condition, and slept on a dirt floor, usually without blankets. The Korean winters are very harsh and cold, and POWs suffered from all the effects of exposure. Periodically, the captured crewmen would be removed from solitary for interrogation, usually lasting three hours, and then were returned to their cells.

When the three-month initial confinement and interrogation phase was completed, the airmen were transported to a central, Chinese-run POW camp. Life was somewhat better there, but not much. Prisoners were allowed limited exercise, which had been prohibited in the North Korean­run prison. They were still completely isolated from any outside contact, including non-Communist radio broadcasts, newspapers, magazines and letters, and were not allowed to have writing materials. In the Chinese camps POWs were issued some clothing, and crude shelter was provided, but captured U.N. personnel certainly were not treated according to the rules and standards set by the Geneva Convention. The 19th BG personnel who had survived when their B-29 was shot down on January 10, 1953, remained in Communist captivity until August 21, 1953. On that date, they were loaded in trucks along with other POWs and taken to the U.N.­Communist POW exchange point.

Responding to Communist propaganda techniques, the United States used B-29s to drop leaflets to persuade North Korean troops to surrender. In early April 1953, for example, a B-29 propaganda drop scattered thousands of leaflets that stated: ‘Many thousands of North Korean soldiers have been killed! Many thousands of young North Korean women will never have husbands! Blame the Communists!’ Those leaflets were designed to arouse homesickness among the North Korean soldiers and to incite them to rebel against their commanders and leaders for continuing the war in the face of relentless air and ground attacks. The leaflet drops were only an occasional diversion, however, from the main bombing campaign.

A 98th BG mission on July 20, 1953, was typical of the late war attacks against North Korean targets. On the afternoon of the 20th, more than 180 aircrews sat in the briefing room, waiting for the mission briefing to begin. The wing commander quickly walked onto the platform, took his seat in front of the crewmen and ordered them to take their seats. The operations officer waited behind the podium while another officer stood to the right of a large, drape-covered wall map. The crews drew a quick breath as the drape was pulled to one side, revealing their evening targets–two airfields near Pyongyang. The operations officer began describing the mission, ‘First aircraft takeoff will be to the north at 1830 hours,’ and as he gave locations and routes, the second officer pointed each out on the map. The Intelligence officer then briefed the crews on the general shape, size and location of the two targets, mentioning what the pre-strike reconnaissance photographs revealed about the target, its defenses, landmarks and the selected offset aiming points (OAPs). When the Intelligence officer was finished, the communications, weather and engineering officers added their information to the briefing.

As the crews exited the briefing room, many crewmen were asking each other: ‘What do you think? Will this be the last mission?’

At 4 p.m., the crews began reassembling to be issued personal equipment–parachutes, side arms, flight helmets, earphones and other equipment needed to perform the mission. The crews then boarded trucks for the trip to the B-29s parked on the steel and cement runways. Each B-29 was a beehive of activity as flight crews began their preflight aircraft inspection. Crews examined every inch of their bomber’s fuselage, wings, tires, guns, propellers and all the other items on their preflight checklist. Each aircraft commander then lined up his crew with their equipment piled behind. He slowly moved down the line of men, inspecting each piece of equipment to verify everything was combat ready. At his command, the crewmen donned their Mae West life jackets and parachutes and began loading all the equipment into the waiting bomber.

‘How about it, Captain, is this the last mission?’ the crewmen asked. He could only answer, ‘It’s the last one…for tonight!’ But all questions were soon put aside as the control tower cleared the crew’s B-29 for takeoff.

As the B-29 rumbled off its assigned parking hardstand and taxied to position on the runway, the crewmen’s anticipation grew. The B-29 turned onto the end of the runway, and the pilot put on the bomber’s brakes and ran the engines up to full power. The aircraft was vibrating, then it surged forward as takeoff power was applied and the brakes released. The four screaming engines pulled the heavy bomber down the runway into the air toward its assigned target near Pyongyang.

The B-29s encountered heavy clouds that obscured the target, even though they were flying under the light from the moon. That was a very dangerous time for the bombers because they had to fly straight and level and could be tracked by prowling Communist night fighters. The bombardiers used radar to locate their target, releasing their 500-pound bombs through the clouds. Even with the thick cloud base, brilliant flashes of flame could be seen through the cloud layer. The B-29s were being tracked by radar-directed anti-aircraft artillery, and flak burst among the bombers. All B-29 crewmen scanned the night sky looking for enemy fighters, but on this mission none approached the bombers. As each B-29 dropped its bombs, it turned away from the target and headed back to base. The crews relaxed when the aircraft landed and were parked back on their hardstand, but the evening’s mission was not over until after the post-mission debriefing.

In the trucks heading for the debriefing, the crewmen returned to the question of whether they had just flown the war’s last mission. As each crew entered the debriefing room, chaplains met them, welcoming them home and giving each a cup of hot chocolate. The crewmen unzipped their flight suits, wet with sweat and stained with dirt, as they went to the assigned debriefing table, where the Intelligence specialist tried to draw out as much information about the mission as possible. Dawn streaked the eastern horizon as the crewmen finally exited the building, moving slowly toward their quarters. At the same time, other men were getting up, ready for the heavy work of preparing the bombers for the next mission.

The mission had been part of the FEAF’s airfield neutralization program, which Brig. Gen. Richard Carmichael called a ‘blaze of glory.’ Those bombing raids against North Korea’s airfields were designed to render them unserviceable for conventional and jet aircraft. The Chinese, under the cover of inclement weather, had flown in approximately 200 aircraft to Uiju airfield in early July 1953. Once the planes had landed, they had been quickly towed to scattered dispersal revetments in the hills adjoining the hard surface highway between Uiju and Sinuiju. Most of these aircraft received some shrapnel damage during the B-29s’ airfield bombing raids.

The Chinese could still ferry in replacement aircraft before the neutral nations’ inspection teams arrived at the various North Korean airfields to record how many aircraft were at the base. Communist combat engineers were authorized to repair the dirt-surfaced runways after the bombings to permit landings of replacement aircraft, but they could not maintain full combat operations. The replacement aircraft were towed into the aircraft revetments to wait for the inspection team’s visit. Once the inspection team counted the number of aircraft on the North Korean airfields, the fields could be brought up to full operational capabilities. The armistice agreement between the U.N. and the Communists included a statement that guaranteed North Korea the right to retain the number of aircraft that were on the airfields and operational at the time the armistice agreement became effective. On July 27, 1953, the last day of the war, two B-29s of the 98th BG and two of the 91st BG flew over North Korea delivering a final round of psychological leaflets.

B-29s flew 1,076 days during the 1,106-day air war in Korea, dropping 160,000 tons of bombs on Communist targets–a greater bomb tonnage than had been dropped on Japan during World War II. Regardless of the many obstacles they faced, B-29 crews performed brilliantly, destroying industrial and military strategic targets in North Korea and supporting U.N. ground troops. The FEAF lost a grand total of 1,406 aircraft and suffered 1,144 men killed and 306 wounded during the war. Thirty FEAF men who had been declared missing were eventually returned to military control, 214 POWs were repatriated under the terms of the armistice agreement, while 35 men were still being held in Communist captivity as of June 1954. The men who flew and supported the B-29s in the Far East Command were an important part of the air war over Korea, but their contribution has seldom been recognized.

  2. A lot of good material in this article–also a lot left out. Much of what is left out is chronicled in my book, Black Tuesday Over Namsi, a True History of the Epic Air Battle of the Korean War (Heritage 2008).

    To put together, in narrative form, a 15-minute battle between MiG-15s and B-29s escorted by F-86s and F-84s took over seven years and several hundred pages of notes taken from both American and Russian eyewitnesses (including my own observations). The result is an accurate, detailed account of what was perhaps the greatest jet engagement in the history of air warfare, one that forever changed the nature of aerial bombardment. Until this book, Namsi was just another forgotten battle in a forgotten war.

    Details of Black Tuesday are available on the Google Preview page.

  3. Interesting read.
    My father, Floyd George McKinney, 1stLt, was on the Sept 1952 bombing mission at Siuho Dam mentioned above and was awarded at least one medal for that run.
    With 307th Bomb Wing, 372nd Squadron.
    Would be nice to hear from others connected to that group.
