Chanute Air Force Base

Chanute Air Force Base was located near Rantoul, Illinois. It included training facilities with partial Minuteman silos. After the base closed in 1993 the Octave Chanute Aerospace Museum included the silos on tours but they had to close them due to maintenance issues. Later, the museum closed entirely.
