Battery Kirby was a concrete gun battery with two M1895 12" guns mounted on M1897 disappearing carriages. A magazine containing two shell rooms and two powder rooms was situated between the two gun emplacements. No hoists were required as the ammunition service was on the same level as the gun platform. By 1910 the carriages were modified for electric retracting motors but no traversing, elevating or depressing motors were installed. The Battery had its own power plant with two 25 KW gasoline motor-generator sets.
Behind emplacement #2 in a separate building was a tool room and a guard room. In the back and to the right of emplacement #1 was a separate building for the latrines, one for officers and one for enlisted.
In 1910 a BC Station and a plotting room below it were added to the Battery. Cost for the plotting room modification was $ 208.48 and for the BC Station, $ 3,440.03. Both were accepted for use 5 Aug 1910.
Part of the Golden Gate Recreation Area (GGNRA) administered by the National Park Service. No period guns or carriages in place.
