Airmen from Minot and Vandenberg Air Force bases conducted an operational test launch of an unarmed Minuteman III missile. The test launch used an intercontinental ballistic missile pulled randomly from a silo on Minot, which was then transported and reassembled at Vandenberg, and launched by crew members from 91st Missile Wing. The ICBM was equipped with a test reentry vehicle, and traveled approximately four thousand two hundred miles to a test range near the Kwajalein Atoll in the Marshall Islands.
