U.S. Naval Ammunition & Net Depot. Shown are giant piles of anti-submarine floats (spheres) and giant cylinders at the Net Depot. Many people were fearful because they thought the spheres were ocean mines. In reality, the floating steel spheres were made to hold up a net made of cable in the ocean around the breakwater entrances to Long Beach and Los Angeles harbors during WWII. Several Japanese subs tried to penetrate the harbor but were attacked and driven off. A derelict Japanese sub that periodically surfaced in the area was finally sunk off Catalina Island (1948-49)
