Joint Base Cape Cod

The Joint Base Cape Cod, is a joint base created by the Commonwealth of Massachusetts and the United States War Department in 1935. Governor James Curley signed the state bill to allocate and purchase land for a military facility, and establishing a formal commission to manage this new state military property and personnel. After 200000 acre of land was secured in Cape Cod, the Massachusetts National Guard began erecting tents and a basic training program in the following year. Formerly the Massachusetts Military Reservation, it was renamed in 2013 to Joint Base Cape Cod.

1970s
Otis Air National Guard Base underwent boundary changes in 1975. This realignment included these installations: Otis Air National Guard Base, Camp Edwards, and the Coast Guard Air Station Cape Cod.

Cape Cod Air Force Station was created when the air force returned in 1978. The U.S. Air Force constructed the Precision Acquisition Vehicle Entry Phased Array Warning System (PAVE PAWS). PAVE PAWS is designed to detect airborne ballistic missiles and monitor orbiting satellites.
