Fat Man
"Fat Man" (also known as Mark III) was the design of the nuclear weapon the United States used for seven of the first eight nuclear weapons ever detonated in history. It is also the most powerful design to ever be used in warfare. A Fat Man device was Atomic bombings of Hiroshima and Nagasaki#Bombing of Nagasaki, detonated over the Japanese city of Nagasaki on 9 August 1945. It was the second and largest of the only two nuclear weapons ever used in warfare. It was dropped from the Boeing B-29 Superfortress ''Bockscar'' piloted by Major Charles Sweeney. Its detonation marked the third nuclear explosion in history. The name Fat Man refers to the wide, round shape. Fat Man was an implosion-type nuclear weapon with a solid plutonium Nuclear reactor core, core, and later with improved cores. The first Fat Man to be detonated was the gadget in the Trinity (nuclear test), Trinity nuclear test less than a month earlier on 16 July at the Holloman Air Force Base, Alamogordo Bombing an ...

393d Bomb Squadron
The 393rd Bomb SquadronOfficially, the 393d Bomb Squadron is part of the 509th Bomb Wing at Whiteman Air Force Base, Missouri. It operates Northrop Grumman B-2 Spirit nuclear-capable strategic bomber aircraft. The squadron was first organized in March 1944 as the 393rd Bombardment Squadron. In November 1944, the squadron transferred to the 509th Composite Group and began training for the delivery of nuclear weapons.

C-54 Skymaster
The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II. Design and development With the looming entry of the United States into World War II, in June 1941 the War Departme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C-46 Commando
The Curtiss C-46 Commando is a low-wing, twin-engine aircraft derived from the Curtiss CW-20 pressurized high-altitude airliner design. Early press reports used the name "Condor III" but the Commando name was in use by early 1942 in company publicity. It was used primarily as a cargo aircraft during World War II, with fold-down seating for military transport and some use in delivering paratroops. Mainly deployed by the United States Army Air Forces, it also served the U.S. Navy/ Marine Corps, which called it R5C. The C-46 filled similar roles as its Douglas-built counterpart, the C-47 Skytrain, with some 3,200 C-46s produced to approximately 10,200 C-47s. After World War II, a few surplus C-46 aircraft were briefly used in their original role as passenger airliners but the glut of surplus C-47s dominated the marketplace and the C-46 was soon relegated to cargo duty. The type continued in U.S. Air Force service in a secondary role until 1968. The C-46 continues in operation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-47 Skytrain
The Douglas C-47 Skytrain or Dakota ( RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years.Parker 2013, pp. 13, 35, 37, 39, 45–47. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military. Approximately 100 countries' armed forces have operated the C-47 with over 60 variants of the aircraft produced. As with the civilian DC-3, the C-47 remains in service, over 80 years after the type's introduction. Design and development The C-47 differed from the civilian DC-3 by way of numerous modifications, including being fitted with a cargo door, hoist attach ...

320th Troop Carrier Squadron
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. History Organization The squadron was organized at Wendover Field, Utah on 17 December 1944 under the temporary command of ...

Utah
Utah is a landlocked state in the Mountain states, Mountain West subregion of the Western United States. It is one of the Four Corners states, sharing a border with Arizona, Colorado, and New Mexico. It also borders Wyoming to the northeast, Idaho to the north, and Nevada to the west. In comparison to all the U.S. states and territories, Utah, with a population of just over three million, is the List of U.S. states and territories by area, 13th largest by area, the List of U.S. states and territories by population, 30th most populous, and the List of U.S. states by population density, 11th least densely populated. Urban development is mostly concentrated in two regions: the Wasatch Front in the north-central part of the state, which includes the state capital, Salt Lake City, and is home to roughly two-thirds of the population; and Washington County, Utah, Washington County in the southwest, which has approximately 180,000 residents.

Wendover Air Force Base
Wendover Air Force Base is a former United States Air Force base in Utah now known as Wendover Airport. During World War II, it was a training base for B-17 and B-24 bomber crews. It was the training site of the 509th Composite Group, the B-29 unit that carried out the atomic bombings of Hiroshima and Nagasaki. After the war, Wendover was used for training exercises, gunnery range and as a research facility. It was closed by the Air Force in 1969, and the base was given to Wendover City in 1977. Tooele County, Utah, assumed ownership of the airport and base buildings in 1998, and the County continues to operate the airfield as a public airport. A portion of the original bombing range is now the Utah Test and Training Range (UTTR) which is used extensively by the Air Force with live fire targets on the range. Origins Wendover Air Force Base's history began in 1940, when the United States Army began looking for additional bombing ranges. The area near the town of Wendover w ...

Project Alberta
Project Alberta, also known as Project A, was a section of the Manhattan Project which assisted in delivering the first nuclear weapons in the atomic bombing of Hiroshima and Nagasaki during World War II. Project Alberta was formed in March 1945, and consisted of 51 United States Army, Navy, and civilian personnel, including one British scientist. Its mission was three-fold. It first had to design a bomb shape for delivery by air, then procure and assemble it. It supported the ballistic testing work at Wendover Army Air Field, Utah, conducted by the 216th Army Air Forces Base Unit (Project W-47), and the modification of B-29s to carry the bombs (Project Silverplate). After completion of its development and training missions, Project Alberta was attached to the 509th Composite Group at North Field, Tinian, where it prepared facilities, assembled and loaded the weapons, and participated in their use. Origins The Manhattan Project began in October 1941, just before U.S. entry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
