Strategic Air Command (SAC) initially had units assigned to Minot AFB in 1958 for air refueling support. The 4136th Strategic Wing was formed 1 September 1958, consisting of the 906th Air Refueling Squadron, followed by the 4136th Combat Defense Squadron that was activated on 1 June 1959.
This first military unit of the U.S. Army devoted exclusively to aviation, today designated the 1st Reconnaissance Squadron, has remained continuously active since its creation. Assigned a role in the Punitive Expedition of the Mexican border in 1916, this squadron became the first air combat unit of the U.S. Army.
