Quote from the Wikipedia article:
“In June 1961, the Department of Defense chose
Whiteman to host the fourth Minuteman ICBM wing. On 17 January 1962, the joint
venture team of Morrison-Knudsen, Paul Hardeman, Inc., Perini Corporation, and
C.H. Leavell & Co. received the prime contract for construction of
hardened, underground launch facilities and 15 launch control centers. The
project called for the excavation of over 2,000,000 cubic yards of earth and
rock.”
