Project Alberta

Project Alberta, also known as Project A, was a special group formed as part of the Manhattan Project. Its job was to help prepare and deliver the first nuclear weapons during the atomic bombings of Hiroshima and Nagasaki in World War II.

The group began in March 1945 and included 51 members from the United States Army, Navy, and civilian scientists, with one scientist from Britain. They had three main tasks: designing a bomb that could be dropped from airplanes, getting and putting together the bomb parts, and helping to test and prepare airplanes to carry the bombs.

Project Alberta worked at Wendover Army Air Field in Utah and helped change B-29s into special planes called Silverplate. Later, the group joined the 509th Composite Group on North Field, Tinian, where they finished getting the bombs ready, loaded them onto planes, and took part in using these weapons.

Origins

The Manhattan Project began in October 1941, just before the United States entered World War II. Its main goal was to produce special materials needed for atomic bombs. In early 1943, a special laboratory called the Los Alamos Laboratory, also known as Project Y, was created to design and build these bombs. Within this laboratory, a group called the Ordnance Division was responsible for how the bombs would be delivered by aircraft.

The early design of a bomb called "Thin Man" was too big for most planes, so tests were done to see how it would fall from the sky. These tests showed that more careful testing was needed. Later tests with different bomb shapes were conducted at various air fields, making sure everything worked correctly as the project continued through the war.

Organization

Project Alberta, also known as Project A, was formed in March 1945. It included 51 personnel from the Army, Navy, and civilian groups. Parsons led the project, with Ramsey as his scientific deputy and Ashworth as his operations officer.

The team had two bomb assembly groups, one for the Fat Man bomb under Commander Bradbury and another for the Little Boy bomb under Birch. There were also specialists for different tasks, such as physics, aircraft ordnance, and medical support. These scientists and technicians moved to Tinian as part of the Manhattan Project to help design, assemble, and deliver the bombs.

Tinian

The Manhattan Project and United States Army Air Forces decided in December 1944 to use the Mariana Islands as a base for operations. In February 1945, officials visited Tinian, an island with good airfields, and chose it as the best place for assembling and launching the atomic bombs.

Construction crews built special buildings for putting the bombs together. Teams traveled from the United States to Tinian to prepare for the missions. By the end of July 1945, all the necessary people and materials had arrived, ready to assemble and drop the bombs as part of World War II.

Bombing of Hiroshima and Nagasaki

Preparations

Project Alberta was formed in March 1945 to help deliver the first nuclear weapons during World War II. Its job was to design a bomb shape for delivery by air and then to build it. The team prepared carefully, testing bomb parts and systems in practice drops. They made sure everything worked correctly before the real missions.

Hiroshima

On August 6, 1945, the B-29 bomber Enola Gay dropped the Little Boy bomb on Hiroshima. Crew members from Project Alberta were on board to operate and monitor the bomb. The mission went as planned, and the bomb was dropped without any major problems.

Nagasaki

Three days later, on August 9, 1945, another B-29 named Bockscar dropped the Fat Man bomb on Nagasaki. Crew members from Project Alberta helped prepare and monitor the bomb for this mission. The mission faced some challenges, like bad weather and technical issues, but it was completed successfully.

Later activities

After Japan surrendered, Project Alberta continued its work. The team had three test assemblies but needed new explosive blocks from another project. Some important parts were made on the island of Tinian. Seven special airplanes flew missions with practice bombs just before the surrender.

Some members of Project Alberta joined a mission to check the damage in Hiroshima and Nagasaki. The rest of the team packed up the unused bomb parts and sent them back to Los Alamos. For security, some parts were dropped into the ocean. The scientists and technicians left Tinian for the United States in September. Project Alberta was then closed down, and most of its members moved to a new division called Z Division, which went to Sandia Base.
