Originally built as an Endicott Period concrete coastal gun battery with six 3" M1902MI rapid fire guns mounted on M1902 Barbette carriages.

This Battery consisted of six emplacements, each with its own 9' by 15' magazine room and an associated utility room. The six utility rooms had various uses, two were store rooms, 3 were tool rooms and one was an oil room. A pentagon shaped Communication's Officer room was located between emplacement #2 and #3. An 11'6" by 21' guard room was located between emplacements #4 and #5. A separate latrine building was located about 100' to the left of emplacement #6. Electrical power was furnished initially from Battery Duncan, only 2.9 KW was required for lighting.

These guns used complete cartridges and the ammunition was stored that way in order to support a high rate of fire. For short periods of time the gun could support as much as 20 to 30 rounds per minute.

The guns of were not affected by the World War I redistribution or the following 1920 disarmament program.

Emplacements #5 and #6 were first relocated to Battery Kirby Beach in 1942 and then to Battery Gates in 1943. All of the guns and carriages were ordered processed for salvage 7 Mar 1946.
