Project Alberta was a section of the Manhattan Project which developed the means of delivering the first atomic bombs, used by the United States Army Air Forces against the Empire of Japan during World War II. Also known as Project A, the mission of Project Alberta was three-fold: (1) design a bomb shape for delivery by airplane, then procure and assemble it; (2) continue the testing work of Army Air Force Projects W-47 (ballistic testing of atomic bomb design) and Silverplate (modification of B-29s to perform the mission); and (3) train aircrews and ordnance crews in preparation for deployment overseas. Project Alberta consisted of approximately 55 scientists, engineers and military personnel who worked in conjunction with the 509th Composite Group, commanded by Colonel Paul W. Tibbets.
