In 2012, Congress demanded the Pentagon come up with recommendations for the location of a third site to base interceptors for the U.S. Ground Based Midcourse (GMD) missile defense system.
Friday 13th September, the Pentagon announced the locations of five candidate sites for a possible future deployment of additional GMD interceptors. They are:
- Fort Drum, NY
- Camp Ethan Allen Training Site, Vermont
- Naval Air Station Portsmouth SERE Training Area, Maine
- Camp Ravenna Joint Training Center, Ohio
- Fort Custer Training Center, Michigan
