Why did the U.S. military fire 1,400 shells at the Los Angeles night sky?
In February 1942, Los Angeles erupted in a massive anti-aircraft barrage against an invisible enemy. While the city braced for a Japanese invasion, the reality was a chaotic mix of war nerves, stray flares, and a single weather balloon, leaving behind only property damage and five tragic civilian deaths.
The incident began in the early hours of February 25, 1942, just one day after the Japanese submarine I-17 shelled an oil field in Goleta. Following a warning from the Office of Naval Intelligence, the city was on edge. At 3:16 am, the 37th Coast Artillery Brigade opened fire, launching over 1,400 shells into the sky. For over an hour, the city was lit by searchlights and artillery bursts, which many observers mistook for enemy aircraft. Despite the intensity of the barrage, no enemy planes were ever present, and the military suffered no losses.
The aftermath revealed the extent of the hysteria. Five civilians died—three in traffic accidents during the blackout and two from heart attacks brought on by the stress of the event. Secretary of the Navy Frank Knox quickly dismissed the event as a false alarm, though public speculation about a cover-up persisted. Theories ranged from secret enemy bases in Mexico to psychological warfare campaigns. Representative Leland M. Ford even called for a Congressional investigation, questioning whether the raid was a staged event to justify moving war industries inland.
Decades later, the U.S. Office of Air Force History provided a definitive explanation in 1983, attributing the chaos to war nerves triggered by a meteorological balloon and exacerbated by shell fragments and flares. The event has since become a fixture of pop culture and conspiracy theories. Notably, a 1942 Los Angeles Times photograph, retouched to enhance contrast, is frequently cited by UFO enthusiasts as evidence of an alien craft, despite the white paint being a standard graphic arts technique of the era. Today, the incident is remembered as a stark example of wartime paranoia.
