SM-65F Atlas
ICBM launch squadron, stationed at Altus AFB, Oklahoma
and assigned to the 11th Bombardment (later Strategic Aerospace) Wing
on 1 July 1961.
The squadron was assigned twelve missiles, based in a 1 x 12 configuration: twelve independent widely dispersed launch sites comprised the missile squadron. In August 1962, the first Atlas F was placed on alert status. In October, all 12 missiles were put on alert status as a result of the Cuban missile crisis.
The Atlas F was the final and most advanced version of the Atlas ICBM and was stored in a vertical position inside underground concrete and steel silos. When stored, the Atlas F sat atop an elevator. If a missile was placed on alert, it was fueled with RP-1 (kerosene) liquid fuel, which could be stored inside the missile for extended periods. If a decision was made to launch the missile, the missile was raised to the surface and the liquid oxygen tank was filled. The launch would occur shortly after completion of this process.
The exposure on the surface that this procedure entailed was the great weakness of the Atlas F. It was exposed and vulnerable during this time. The Titan II and Minuteman missiles could be launched from within their silos, thereby eliminating this vulnerability. Also, since the Titan did not use a cryogenic fuel or oxydizer, and the Minuteman was a solid fuel rocket, they could be stored fully fueled and ready to launch within a very few minutes.
The 577th SMS operated twelve launch silos; one missile at each site. The missiles were retired and removed in early 1965 in favor of the more advanced LGM-25C Titan II; squadron was inactivated on 25 March 1965. Missile sites were later sold off to private ownership after demilitarization.
Note: *The missile at this site exploded in May, 1964
