Battle of Los Angeles

The Event Incident in which sightings of unidentified aircraft, presumed to be part of Japanese attacks, prompted antiaircraft fire

Date February 24-25, 1942

Place Los Angeles, California

After the attack on Pearl Harbor on December 7, 1941, the American public feared that Japan would next attack the mainland United States. Less than three months after the United States entered World War II, residents of Los Angeles awoke one night to air sirens and antiaircraft fire. The cause of the incident remains unexplained.

On February 23, 1942, a Japanese submarine fired on an oil production facility near Santa Barbara, California, and reportedly was heading toward Los Angeles. On the night of February 24 and early morning of February 25, strange objects appeared above Los Angeles. At 2:25 a.m. on February 25, air-raid sirens were sounded, a blackout was ordered, and air-raid wardens were mobilized. From 3:16 to 4:14 a.m., the military fired antiaircraft guns at supposed objects illuminated by nine searchlight beams. Military aircraft were ordered on standby alert but never took off. At 7:21 a.m., an “all clear” was sounded, and the blackout order was lifted.

The identity of the flying objects has never been determined. Speculation has included weather balloons, blimps, Japanese fire balloons, extraterrestrial vessels, sky lanterns, or unauthorized commercial or private airplanes.

Impact

The artillery damaged several buildings and killed three civilians. Three others died from heart attacks, reportedly due to stress over the incident.

Soon afterward, Secretary of the Navy Frank Knox announced that the incident was due to anxiety and “war nerves.” Conflicting reports were written by Army and Navy officers. The public was not told at the time that up to five unidentified airplanes were sighted and that one of these was later recovered off the coast of California. In 1945, Japan denied any involvement in the incident.
