Tuskegee Airmen
is the popular name of a group of African-American military pilots (fighter and bomber) who fought in World War II.
 Officially, they formed the 332nd Fighter Group and the 477th Bombardment Group of the United States Army Air Forces.
 The name also applies to the navigators, bombardiers, mechanics, instructors, crew chiefs, nurses, cooks and other support personnel for the pilots.
1st Proving Ground Group
The 1st Proving Ground Group is a disbanded United States Army Air Forces unit.
 It was last active with the Army Air Forces Proving Ground Command, based at Eglin Field, Florida, where it was disbanded on 1 April 1944.
 The unit's personnel/equipment/mission was taken over by the 610th Army Air Forces Base Unit (AAF Base Unit) and 611th AAF Base Unit. Bockscar
Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second – and last – nuclear attack in history.
 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 393d Bombardment Squadron, 509th Composite Group to Wendover Army Air Field, Utah in April. United States Strategic Air Forces in Europe
The United States Strategic Air Forces (USSTAF) was a formation of the United States Army Air Forces.
 It became the overall command and control authority of the United States Army Air Forces in Europe during World War II. United States Army Air Corps
The United States Army Air Corps (USAAC) was the military aviation arm of the United States of America between 1926 and 1941.
 After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness.
 The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army.
 The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure.
 During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force. Army Air Forces School of Applied Tactics
The Army Air Forces School of Applied Tactics (known as AAFSAT) was a major command of the United States Army Air Forces.
 It was merged with Army Air Forces Proving Ground Command on 8 March 1946 at Orlando Army Airbase, Florida. North American T-6 Texan
The North American Aviation T-6 Texan is an American single-engined advanced trainer aircraft used to train pilots of the United States Army Air Forces (USAAF), United States Navy, Royal Air Force, and other air forces of the British Commonwealth during World War II and into the 1970s.
 Designed by North American Aviation, the T-6 is known by a variety of designations depending on the model and operating air force.
 The United States Army Air Corps (USAAC) and USAAF designated it as the AT-6, the United States Navy the SNJ, and British Commonwealth air forces the Harvard, the name by which it is best known outside of the US.
 Starting in 1948, the new United States Air Force (USAF) designated it the T-6, with the USN following in 1962.
 It remains a popular warbird aircraft used for airshow demonstrations and static displays.
 It has also been used many times to simulate various Japanese aircraft, including the Mitsubishi A6M Zero in movies depicting World War II in the Pacific. United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the military aviation service of the United States of America during and immediately after World War II, successor to the United States Army Air Corps and the direct predecessor of the United States Air Force.
 The AAF was a component of the United States Army, which in 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces.
 Each of these forces had a commanding general who reported directly to the Army Chief of Staff. Continental Air Forces
Continental Air Forces (CAF) was a United States Army Air Forces major command at the end of World War II and during the early Cold War for combat training of bomber and fighter personnel and for Continental United States (CONUS) air defense after the Aircraft Warning Corps and Ground Observer Corps were placed in standby during 1944.
 CAF conducted planning for the postwar United States general surveillance radar stations, and the planning to reorganize to a separate USAF was for CAF to become the USAF Air Defense Command (ADC was headquartered at CAF's Mitchel Field instead of the CAF HQ at Bolling Field.)
 On 21 March 1946, CAF headquarters personnel and facilities at Bolling Field, along with 1 of the 4 CAF Air Forces (2nd—which had its HQ inactivated on 30 March ) became Strategic Air Command.
 US Strategic Air Forces of WWII, e.g., Eighth Air Force and Fifteenth Air Force, transferred later to SAC.
 Most of the CAF airfields that had not been distributed to other commands when SAC activated were subsequently transferred to Air Defense Command (to which CAF's 1st & 4th Air Forces were assigned on 21 March), Tactical Air Command (3rd Air Force), and Air Materiel Command from 23 March 1946 to 16 March 1947 before the USAF was activated in September 1947.
