World War II (1941-1945) Part of the Harbor Defense of San Francisco. Battery Townsley and Battery Davis (2) at Fort Funston were two 16" batteries planned to guard the entrance to San Francisco harbor. Battery Townsley was a casemated battery with two naval MarkII-M1 16" guns mounted on long-range Barbette M1919 M5 carriages, each capable of shooting a 2,100 pound, armor-piercing projectile 25 miles out to sea. The guns and their associated ammunition magazines, power rooms, and crew quarters were covered by dozens of feet of concrete and earth to protect them from air and naval attack. The central traverse magazine, in addition to the two casemated guns, included two separate magazines. Each magazine included: 2 Powder Rooms 2 Shell Rooms 2 Powder Service Rooms 4 Storerooms The central section of the Battery included the power room, radiator room, latrines, a shop, and a storeroom. In 1943, additional latrine facilities were installed in the main entrance to the Central Traverse Magazine and prison style bunk facilities for 150 people were installed in the corridors, storeroom, and shop at a cost of $4,570.44. Reserve Magazine Plan A large reserve magazine was built about 2500 feet southeast of gun emplacement #1 on the reverse slope of the battery, not visible from the sea. The reserve magazine construction began June 1938, was completed 1 Jul 1940 and was accepted for service 24 Jul 1940 at a cost of $52,950. Battery Townsley PSR Plan A separate PSR (Plotting, Spotting & Radio Rooms) was built about 1,200' away from the Battery to isolate it from the concussion of the 16" guns firing. The PSR construction was accepted for service 24 Jul 1940 at a cost of $76,400. In 1943, prison style bunk facilities for thirty people were installed in the PSR at a cost of $420 and accepted for service on 16 Aug 1943. The total cost of the Battery including the reserve magazine, PSR, BC stations and real property improvements rose to $1,007,500 by 1940. Test firings in 1940 with live ammunition proved the range to be over 30 miles.
