Battery 127 was a battery of two, 16", Mark II-M1, Long Range naval guns on M1919 M4 Barbette carriages. Each gun position was in a reinforced concrete casemate. The casemates were 500' apart at either end of an earth covered reinforced concrete support structure. Construction began Apr 1942 and was completed Dec 1943. The Battery was turned over for service 11 Sep 1944 at a cost of $1,256,410.

The 16" guns could fire one-ton projectiles nearly 28 miles and covered most of the northern approach to the Los Angeles Harbor.
