Battery Yates History

Part of the Harbor Defense of San Francisco. provided protection for the inner harbor mine fields.

Endicott Period

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 it's 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.
