Credit U.S. Space Force Installation officials say the name-change won’t affect Clear’s main mission, which is to scan the horizon for incoming enemy missiles and alerting the U.S. missile defense system, including the base at Fort Greely, to the threat. Clear’s ability to carry out that mission will be greatly enhanced in 2023 when an advanced, $1.5 billion radar system becomes operational. Construction work on the Long Range Discrimination Radar has been completed, and the Missile Defense Agency hopes to conduct a key operational flight test for the LRDR next year. There are no Space Force personnel at Clear. Officials say for now Air Force military and civilian personnel will continue to operate the installation.
