The Enola Gay is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction. Enola Gay participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki being bombed instead.
After the war, the Enola Gay returned to the United States, where it was operated from Roswell Army Air Field, New Mexico. It was flown to Kwajalein for the Operation Crossroads nuclear tests in the Pacific, but was not chosen to make the test drop at Bikini Atoll. Later that year it was transferred to the Smithsonian Institution, and spent many years parked at air bases exposed to the weather and souvenir hunters, before being disassembled and transported to the Smithsonian's storage facility at Suitland, Maryland, in 1961.
In the 1980s, veterans groups began agitating for the Smithsonian to put the aircraft on display. The cockpit and nose section of the aircraft were exhibited at the National Air and Space Museum (NASM) in downtown Washington, D.C., for the bombing's 50th anniversary in 1995, amid a storm of controversy. Since 2003, the entire restored B-29 has been on display at NASM's Steven F. Udvar-Hazy Center. The last survivor of its crew, Theodore Van Kirk, died on July 28, 2014, at the age of 93.

World War II
The Enola Gay (Model number B-29-45-MO,[N 1] Serial number 44-86292, Victor number 82) was built by the Glenn L. Martin Company (now Lockheed Martin) at its Bellevue, Nebraska plant, located at what is now known as Offutt Air Force Base. The bomber was one of 15 B-29s with the "Silverplate" modifications necessary to deliver atomic weapons. These modifications included an extensively modified bomb bay with pneumatic doors and British bomb attachment and release systems, reversible pitch propellers that gave more braking power on landing, improved engines with fuel injection and better cooling, and the removal of protective armor and gun turrets.
Enola Gay was personally selected by Colonel Paul W. Tibbets, Jr., the commander of the 509th Composite Group, on 9 May 1945, while still on the assembly line. The aircraft was accepted by the United States Army Air Forces (USAAF) on 18 May 1945 and assigned to the 393d Bombardment Squadron, Heavy, 509th Composite Group. Crew B-9, commanded by Captain Robert A. Lewis, took delivery of the bomber and flew it from Omaha to the 509th's base at Wendover Army Air Field, Utah, on 14 June 1945.
Thirteen days later, the aircraft left Wendover for Guam, where it received a bomb-bay modification, and flew to North Field, Tinian, on 6 July. It was initially given the Victor (squadron-assigned identification) number 12, but on 1 August, was given the circle R tail markings of the 6th Bombardment Group as a security measure and had its Victor number changed to 82 to avoid misidentification with actual 6th Bombardment Group aircraft. During July, the bomber made eight practice or training flights, and flew two missions, on 24 and 26 July, to drop pumpkin bombs on industrial targets at Kobe and Nagoya. Enola Gay was used on 31 July on a rehearsal flight for the actual mission.
The partially assembled Little Boy gun-type nuclear weapon L-11 was contained inside a 41-inch (100 cm) x 47-inch (120 cm) x 138-inch (350 cm) wooden crate weighing 10,000 pounds (4,500 kg) that was secured to the deck of the USS Indianapolis. Unlike the six Uranium-235 target discs, which were later flown to Tinian on three separate aircraft arriving 28 and 29 July, the assembled projectile with the nine Uranium-235 rings installed was shipped in a single lead-lined steel container weighing 300 pounds (140 kg) that was securely locked to brackets welded to the deck of Captain Charles B. McVay III's quarters.[N 2] Both the L-11 and projectile were dropped off at Tinian on 26 July 1945.
On 5 August 1945, during preparation for the first atomic mission, Tibbets assumed command of the aircraft and named it after his mother, Enola Gay Tibbets, who had herself been named for the heroine of a novel.[N 3] When it came to selecting a name for the plane, Tibbets later recalled that:
my thoughts turned at this point to my courageous red-haired mother, whose quiet confidence had been a source of strength to me since boyhood, and particularly during the soul-searching period when I decided to give up a medical career to become a military pilot. At a time when Dad had thought I had lost my marbles, she had taken my side and said, "I know you will be all right son."
The name was painted on the aircraft on 5 August by Allan L. Karl, an enlisted man in the 509th. Regularly assigned aircraft commander Robert Lewis was unhappy to be displaced by Tibbets for this important mission, and became furious when he arrived at the aircraft on the morning of 6 August to see it painted with the now-famous nose art.
Hiroshima was the primary target of the first nuclear bombing mission on 6 August, with Kokura and Nagasaki as alternative targets. Enola Gay, piloted by Tibbets, took off from North Field, about six hours' flight time from Japan, accompanied by two other B-29s, The Great Artiste, carrying instrumentation, and a then-nameless aircraft later called Necessary Evil, commanded by Captain George Marquardt, to take photographs. The director of the Manhattan Project, Major General Leslie R. Groves, Jr., wanted the event recorded for posterity, so the takeoff was illuminated by floodlights. When he wanted to taxi, Tibbets leaned out the window to direct the bystanders out of the way. On request, he gave a friendly wave for the cameras.
After leaving Tinian the aircraft made their way separately to Iwo Jima, where they rendezvoused at 2,440 meters (8,010 ft) and set course for Japan. The aircraft arrived over the target in clear visibility at 9,855 meters (32,333 ft). Captain William S. "Deak" Parsons of Project Alberta, who was in command of the mission, armed the bomb during the flight to minimize the risks during takeoff. His assistant, Second Lieutenant Morris R. Jeppson, removed the safety devices 30 minutes before reaching the target area.
The release at 08:15 (Hiroshima time) went as planned, and the Little Boy took 43 seconds to fall from the aircraft flying at 31,060 feet (9,470 m) to the predetermined detonation height about 1,968 feet (600 m) above the city. Enola Gay traveled 11.5 mi (18.5 km) before it felt the shock waves from the blast. Although buffeted by the shock, neither Enola Gay nor The Great Artiste was damaged.
The detonation created a blast equivalent to 16 kilotons of TNT (67 TJ). The U-235 weapon was considered very inefficient, with only 1.7% of its fissile material fissioning. The radius of total destruction was about one mile (1.6 km), with resulting fires across 4.4 square miles (11 km2). Americans estimated that 4.7 square miles (12 km2) of the city were destroyed. Japanese officials determined that 69% of Hiroshima's buildings were destroyed and another 6–7% damaged. Some 70,000–80,000 people, or some 30% of the city's population, were killed by the blast and resultant firestorm, and another 70,000 injured. Out of those killed, 20,000 were soldiers.
Enola Gay returned safely to its base on Tinian to great fanfare, touching down at 2:58 pm, after 12 hours 13 minutes. The Great Artiste and Necessary Evil followed at short intervals. Several hundred people, including journalists and photographers, had gathered to watch the planes return. Tibbets was the first to disembark, and was presented with the Distinguished Service Cross on the spot.
The Hiroshima mission was followed by another atomic strike. Originally scheduled for 11 August, it was brought forward by two days to 9 August owing to bad weather. This time, a Fat Man nuclear weapon was carried by B-29 Bockscar, piloted by Major Charles W. Sweeney. Enola Gay, flown by Captain George Marquardt's Crew B-10, was the weather reconnaissance aircraft for Kokura, the primary target. Enola Gay reported clear skies over Kokura, but by the time Bockscar arrived, the city was obscured by smoke from fires from the conventional bombing of Yawata by 224 B-29s the day before. After three unsuccessful passes, Bockscar diverted to its secondary target, Nagasaki, where it dropped its bomb. In contrast to the Hiroshima mission, the Nagasaki mission has been described as tactically botched, although the mission did meet its objectives. The crew encountered a number of problems in execution, and had very little fuel by the time it landed at Yontan Airfield on Okinawa.
Enola Gay's crew on 6 August 1945, consisted of 12 men. The crew was:
- Colonel Paul W. Tibbets, Jr. – pilot and aircraft commander
- Captain Robert A. Lewis – co-pilot; Enola Gay's regularly assigned aircraft commander*

On 6 November 1945, Lewis flew the Enola Gay back to the United States, arriving at the 509th's new base at Roswell Army Air Field, New Mexico, on 8 November. On 29 April 1946, Enola Gay left Roswell as part of Operation Crossroads nuclear tests in the Pacific. It flew to Kwajalein on 1 May. It was not chosen to make the test drop at Bikini Atoll and left Kwajalein on 1 July, the date of the test, reaching Fairfield-Suisun Army Air Field, California, the next day.
The decision was made to preserve the Enola Gay, and on 24 July 1946, the aircraft was flown to Davis-Monthan Air Force Base, Arizona, in preparation for storage. On 30 August 1946, the title to the aircraft was transferred to the Smithsonian Institution and the Enola Gay was removed from the USAAF inventory. From 1946 to 1961, the Enola Gay was put into temporary storage at a number of locations. It was at Davis-Monthan from 1 September 1946 until 3 July 1949, when it was flown to Orchard Place Air Field, Park Ridge, Illinois, by Tibbets for acceptance by the Smithsonian. It was moved to Pyote Air Force Base, Texas, on 12 January 1952, and then to Andrews Air Force Base, Maryland, on 2 December 1953, because the Smithsonian had no storage space for the aircraft.
It was hoped that the Air Force would guard the plane but, lacking hangar space, it was left outdoors on a remote part of the air base, exposed to the elements. Souvenir hunters broke in and removed parts. Insects and birds then gained access to the aircraft. Paul E. Garber, the first head of the National Air Museum of the Smithsonian Institution, became concerned about the Enola Gay 's condition, and on 10 August 1960, Smithsonian staff began dismantling the aircraft. The components were transported to the Smithsonian storage facility at Suitland, Maryland, on 21 July 1961.
Enola Gay remained at Suitland for many years. By the early 1980s, two veterans of the 509th, Don Rehl and his former navigator in the 509th, Frank B. Stewart, began lobbying for the aircraft to be restored and put on display. They enlisted Tibbets and Senator Barry Goldwater in their campaign. In 1983, Walter Boyne, a former B-52 pilot with the Strategic Air Command, became director of the National Air and Space Museum, and he made the Enola Gay 's restoration a priority. Looking at the aircraft, Tibbets recalled, was a "sad meeting. [My] fond memories, and I don't mean the dropping of the bomb, were the numerous occasions I flew the airplane.... I pushed it very, very hard and it never failed me.... It was probably the most beautiful piece of machinery that any pilot ever flew."
Restoration of the bomber began on 5 December 1984, at the Paul E. Garber Preservation, Restoration, and Storage Facility in Suitland-Silver Hill, Maryland. The propellers that were used on the bombing mission were later shipped to Texas A&M University. One of these propellers was trimmed to 12.5 feet (3.8 m) for use in the university's Oran W. Nicks Low Speed Wind Tunnel. The lightweight aluminium variable-pitch propeller is powered by a 1,250 kVA electric motor providing a wind speed up to 200 miles per hour (320 km/h). Two engines were rebuilt at Garber and two at San Diego Air & Space Museum. The work was slow and meticulous. Every component was carefully cleaned. Some parts and instruments had been removed and could not be located. Replacements were found or fabricated, and marked so that future curators could distinguish them from the original components.
Enola Gay became the center of a controversy at the Smithsonian Institution when the museum planned to put its fuselage on public display in 1995 as part of an exhibit commemorating the 50th anniversary of the atomic bombing of Hiroshima. The exhibit, The Crossroads: The End of World War II, the Atomic Bomb and the Cold War, was drafted by the Smithsonian's National Air and Space Museum staff, and arranged around the restored Enola Gay.
Critics of the planned exhibit, especially those of the American Legion and the Air Force Association, charged that the exhibit focused too much attention on the Japanese casualties inflicted by the nuclear bomb, rather than on the motivations for the bombing or the discussion of the bomb's role in ending the conflict with Japan. The exhibit brought to national attention many long-standing academic and political issues related to retrospective views of the bombings. As a result, after various failed attempts to revise the exhibit in order to meet the satisfaction of competing interest groups, the exhibit was canceled on 30 January 1995. Martin O. Harwit, Director of the National Air and Space Museum, was compelled to resign over the controversy.
The forward fuselage did go on display on 28 June 1995. On 2 July 1995, three people were arrested for throwing ash and human blood on the aircraft's fuselage, following an earlier incident in which a protester had thrown red paint over the gallery's carpeting. The exhibition closed on 18 May 1998, and the fuselage was returned to the Garber Facility for final restoration.
Complete restoration and display
Restoration work began in 1984, and would eventually require 300,000 staff hours. While the fuselage was on display, from 1995 to 1998, work continued on the remaining unrestored components. The aircraft was shipped in pieces to the National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia from March–June 2003, with the fuselage and wings reunited for the first time since 1960 on 10 April 2003 and assembly completed on 8 August 2003. The aircraft is currently at Washington Dulles International Airport in the Steven F. Udvar-Hazy Center, since the museum annex opened on 15 December 2003.
- The block number was a one to three digit number followed by a two letter code that represented the aircraft built to the same engineering specification. The two letter code represented the plant at which the aircraft was built, in this case, Martin in Omaha. This was combined with the aircraft model designation (B-29) to form the model number
