On February 25, 1942 — just 79 days after the Pearl Harbor attack — U.S. Army anti-aircraft batteries across the Los Angeles area opened fire on an unidentified object tracked by military radar. Searchlights illuminated the sky; air raid sirens woke the city. The Army fired approximately 1,430 rounds of anti-aircraft ammunition. The object — described by observers as moving, glowing, and unaffected by the barrage — was never brought down. The Los Angeles Times front-page photograph of intersecting searchlights converging on a bright object became one of the most reproduced images in UFO history. Secretary of War Henry Stimson publicly acknowledged that an unidentified object had been present over Los Angeles. The incident preceded Roswell by five years and is now documented in declassified Army Air Forces and Western Defense Command records.
At approximately 2:15 AM on February 25, 1942, radar operators at the Western Defense Command detected an unidentified object approaching the Los Angeles coastline. An air raid warning was issued at 2:25 AM — the first wartime blackout order over a major American city. Anti-aircraft batteries on the coast began firing at 3:16 AM under orders from Brig. Gen. William Ord Ryan. The firing continued until approximately 4:14 AM. An estimated 1,430 rounds of 12.8 lb anti-aircraft shells were expended.
Witnesses across the Los Angeles basin — from Long Beach to Santa Monica — reported observing glowing objects moving through the searchlight beams. Some described a single large object; others reported multiple smaller objects in formation. The object or objects appeared to be moving at low speed and were not brought down despite concentrated fire. Three civilians were killed in the incident — not by the object but by falling shell fragments and heart attacks induced by the blackout confusion. The firing ceased and the all-clear was sounded at 7:21 AM.
The official Army Air Forces investigation was conducted immediately following the incident. The Western Defense Command report acknowledged that an unidentified object had been tracked by radar and observed visually by multiple military personnel. Secretary of War Henry Stimson — in a public statement on February 25 — acknowledged the presence of unidentified aircraft over Los Angeles, describing them as possibly 'commercial planes operated by enemy agents for psychological purposes.' He simultaneously acknowledged that the Army could not definitively identify the objects.
The Secretary of the Navy Frank Knox issued a different statement the same day, attributing the incident to 'war nerves' and claiming no aircraft had been present. The contradiction between Stimson's 'unidentified aircraft present' and Knox's 'nothing was there' created a lasting official confusion about the incident. A subsequent Office of Air Force History study in 1983 concluded that the unidentified radar return was likely a weather balloon that triggered the alert — but acknowledged the visual observations by dozens of military personnel and civilians remain unexplained. The 1942 Army report is now archived in NARA.
The Los Angeles Times front-page photograph taken by staff photographer Harry Case on the night of the incident shows converging searchlight beams illuminating what appears to be a bright, structured object surrounded by anti-aircraft burst clouds. The photograph has been scrutinized for decades. Photo analysts have noted that the object visible in the searchlight convergence point does not match the typical profile of a weather balloon.
The photograph was analyzed by the Ground Saucer Watch organization in the 1970s using early computer enhancement, which suggested the object had a defined structure inconsistent with a balloon or natural phenomenon. More recently, digital enhancement has been applied to the original negative. The Army Air Forces' own contemporaneous assessments noted that observers with binoculars described the object as 'orange or amber in color with a definite outline.' The image remains one of the most widely cited pieces of photographic evidence in the pre-Cold War aerial anomaly record and is catalogued in Western Defense Command files at NARA.
The 2026 NARA RG 615 and PURSUE program releases have not added substantially to the Battle of Los Angeles record compared to what was already available in Western Defense Command declassified files — the incident predates Project Sign and the formal UAP investigation framework by six years. However, the PURSUE releases have re-contextualized the incident within the broader pattern of aerial anomalies that prompted the formal investigation programs of 1947–1969.
The incident's significance for the modern archive is primarily contextual: it demonstrates that the U.S. military's encounter with unidentified aerial objects predates the Roswell era and that the pattern of official divergence between branches of government — Army acknowledging an object, Navy denying it — is a structural feature of UAP incidents rather than a modern artifact. The official status of the Battle of Los Angeles as of 2026 remains what it was in 1942: no definitive identification of what was fired at. The 1983 weather balloon hypothesis is the current official working explanation, but it does not account for the radar track, the military observers' visual descriptions, or the structured appearance in the Times photograph.

Materials recovered near Roswell, NM. A hexagonal disc approximately 20 feet in diameter was documented, suspended from a balloon. Modern re-analysis notes 'composition inconsistent with known terrestrial alloys'.
Multiple unidentified objects were tracked on radar at Washington National Airport and Andrews AFB on two separate weekends in July 1952. USAF interceptors were scrambled twice; objects vanished when jets arrived and returned when jets departed. This prompted the largest Air Force press conference since World War II and remains one of the best-documented mass radar UAP events in U.S. history.
