By 1919, construction had been completed on Fort MacArthur’s main armament of four 14-inch rifles mounted on ingenious “disappearing carriages” and eight 12-inch mortars mounted in massive concrete emplacements. These guns protected Los Angeles Harbor and had a range of up to fourteen miles. In addition to the big guns, electrically controlled mines were stored on the Lower Reservation for rapid deployment across the harbor entrance and were protected from enemy mine sweepers by four 3-inch rapid fire guns located on a sand spit off the end of what is today known as Terminal Island. - The Fort MacArthur Museum Association
