The Enola Gay is a Boeing B-29 Superfortress bomber, named after Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb in warfare. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and destroyed about three-quarters of the city. Enola Gay participated in the second nuclear attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki, a secondary target, being bombed instead.
The Great Artiste was a U.S. Army Air Forces Silverplate B-29 bomber, assigned to the 393d Bomb Squadron, 509th Composite Group.

It flew 12 training and practice missions in which it bombed Japanese-held Pacific islands and dropped pumpkin bombs on targets in Japan. It was the only aircraft to have participated in both the bombings of Hiroshima and Nagasaki, albeit as an observation aircraft on each mission.

The mission was flown by crew C-14 but with Group Operations Officer Major James I. Hopkins, Jr., as the aircraft commander.
Silverplate was the code reference for the United States Army Air Forces' participation in the Manhattan Project during World War II. Originally the name for the aircraft modification project which enabled a B-29 Superfortress bomber to drop an atomic weapon, "Silverplate" eventually came to identify the training and operational aspects of the program as well. The original directive for the project had as its subject line "Silver Plated Project," but continued usage of the term shortened it to "Silverplate".
Some Punkins was the name of a B-29 Superfortress modified to carry an atomic bomb during World War II.
Pumpkin bombs were conventional aerial bombs developed by the Manhattan Project and used by the United States Army Air Forces against Japan during World War II. It was a close replication of the Fat Man plutonium bomb with the same ballistic and handling characteristics, but it used non-nuclear conventional high explosives. It was mainly used for testing and training purposes, which included combat missions flown with pumpkin bombs by the 509th Composite Group. The name "pumpkin bomb" was the term used in official documents from the large, fat ellipsoidal shape of the munition casing instead of the more usual cylindrical shape of other bombs, intended to enclose the Fat Man's spherical "physics package".
Next Objective was the name of a Boeing B-29-36-MO Superfortress, 44-27299, Victor 86, modified to carry the atomic bomb in World War II.
Top Secret was the name of a Boeing B-29 Superfortress modified to carry the atomic bomb in World War II. It served with the Army Air Forces and United States Air Force from 1945 until 1954.

One of 15 Silverplate B-29s used by the 509th, Bockscar was built at the Glenn L. Martin Aircraft Plant at Bellevue, Nebraska, at what is now Offutt Air Force Base, and delivered to the United States Army Air Forces on 19 March 1945. It was assigned to the 393rd Bombardment Squadron, 509th Composite Group to Wendover Army Air Field, Utah, in April and was named after captain Frederick C. Bock.
The 320th Troop Carrier Squadron is an inactive United States Air Force unit. It was activated on 17 December 1944, and inactivated on 19 August 1946 at Roswell Army Air Field, New Mexico. The squadron was later consolidated with the 302d Transport Squadron and 302d Tactical Reconnaissance Squadron. The squadron was a support squadron for the 509th Composite Group during World War II. It was formed as the transport unit for the 509th, and due to the highly secret nature of the group, carried all supplies and equipment for Project Silverplate Atomic Bomb activities. It also functioned as a special air transport squadron for high-ranking officers, nuclear scientists and for the group's commander, Lt. Col. Paul Tibbets to meetings concerning Silverplate. The squadron later served as a transport squadron for atomic tests in the Marshall Islands in 1946.
The 216th Army Air Forces Base Unit (Special) provided base services at Wendover Army Airfield, where the 509th Composite Group was stationed during World War II. As such, it became involved in the Manhattan Project's program of testing bombs and aircraft under the codename Project W-47.
