The M1909 was a wire-wound gun 40 calibers long designed specifically for the turrets of Fort Drum on El Fraile Island in Manila Bay, Philippines.
An unusual design feature was that it was made without trunnions.
The turrets were made by Newport News Shipbuilding.
Fort Drum was built by razing the small island down to the water and building a massive concrete fort on it.
The fort had four 14-inch M1909 guns in two twin M1909 turrets, with four 6-inch M1908 guns in casemates on the sides.
Despite holding out against Japanese bombardment, the fort was surrendered after destroying the guns along with Corregidor on 6 May 1942.
It was recaptured in April 1945 by Company F of the 2nd Battalion, 151st Infantry Regiment, 38th Infantry Division, and a detachment of the 113th Engineer Combat Battalion of the same division.
The engineers lowered a 500-pound TNT charge into the structure with a 30-minute time fuze.
They then pumped in 3400 gallons of fuel consisting of 75% diesel and 25% gasoline.
