Originally, the fort was to be the control center for a mine web link across the Bay.
The fort was topped with a pair of armored steel gun turrets, each mounting two 14 inch guns.
Searchlights, anti-aircraft batteries, and a fire direction tower were also mounted on its upper surface.
In a bid to recapture Manila, Fort Drum was assaulted by US forces on April 1945.
