Calf Island Military Reservation was a World War II coastal defense site located on Calf Island in Hull, Massachusetts.
In 1920 there was a proposal to build a naval-type turret with two 16-inch guns on Great Brewster Island, but this was not implemented. Calf Island was also considered, but the battery was finally built (without a turret) as Fort Duvall.
The Calf Island Military Reservation was built in 1941 on state land. It consisted of an early SCR-268 radar, searchlight station, and an observation post. It was returned to the state in 1946.
The site today consists of the foundation of the observation tower.
