Following the creation of the independent Air Force service in the United States military in 1947, discussions had already been underway at senior levels regarding the introduction of a new uniform that would distinguish the service from the uniform of its former parent service, the Army. After extensive development and testing, a service dress uniform in blue shade number 84 was introduced for wear in 1949, similar in appearance to the uniform worn by the Royal Air Force. Slow distribution and low stocks of the uniform however meant that it was not widely issued until 1950, but the uniform remained largely unchanged until a darker shade of blue was stipulated in 1967.
