The 1973 National Personnel Records Center Fire
In the early hours of July 12, 1973, a fire broke out on the sixth floor of the National Personnel Records Center (NPRC) in Overland, Missouri, a suburb of St. Louis. Over the next four days, flames consumed an entire floor of irreplaceable military service files, destroying records for millions of American veterans. The disaster remains one of the most consequential losses in the history of U.S. government record-keeping, complicating veterans' benefits claims for decades afterward.
A Fire Without Warning
Shortly after midnight on July 12, 1973, firefighters were called to the Military Personnel Records Center building at 9700 Page Avenue in Overland, Missouri. The sixth floor, a vast open space packed with paper files stored on wooden shelving, had no sprinkler system installed, a fateful omission that allowed the blaze to spread rapidly through the densely packed records. Firefighters battled the flames for more than 22 hours before bringing the main fire under control, but smoldering paper and structural hot spots kept crews returning to the scene for days. The fire was not fully extinguished until July 16, five days after it began. By the time the smoke cleared, the entire sixth floor, roughly 22,000 square feet of records storage, had been gutted. Investigators were never able to determine a definitive cause, though accidental origins such as a discarded cigarette were considered the most likely explanation. No evidence of arson was ever confirmed. The scale of destruction was staggering: an estimated 16 to 18 million Official Military Personnel Files, documenting the service of millions of Americans who had served in the Army and Air Force, were reduced to ash or water-damaged beyond recovery.
Did You Know?
Because no duplicate copies of the destroyed records existed anywhere, NPRC archivists still reconstruct veterans' service histories today, more than 50 years later, by piecing together secondary evidence like military pay vouchers and unit morning reports.
What Was Lost
The fire's damage fell almost entirely on two specific record groups. Approximately 80 percent of Army personnel records for soldiers discharged between November 1, 1912, and January 1, 1960, were destroyed. Similarly, about 75 percent of Air Force personnel records for airmen with surnames falling alphabetically after 'Hubbard, James E.' and discharged between September 25, 1947, and January 1, 1964, were lost. Because the Air Force had only become a separate service in 1947, many of its earliest personnel files were caught in the same catastrophe. Crucially, no duplicate copies or microfilm backups existed for these records at the time; the paper originals housed at the NPRC were the sole official record of service for millions of veterans, including many who had served in World War I, World War II, and the Korean War. This meant the fire did not simply damage a copy, it erased the primary documentation of service dates, discharge status, awards, and medical history for an enormous swath of the American military population from the first half of the 20th century.
Aftermath and Reconstruction Efforts
The consequences of the fire extended far beyond the burned building. Veterans who needed their military records to claim disability compensation, pension benefits, or medical care through the Department of Veterans Affairs suddenly found themselves without proof of service. In response, the NPRC established a painstaking reconstruction program, cross-referencing alternate sources such as unit morning reports, pay vouchers, state adjutant general records, and organizational rosters to piece together partial service histories. This labor-intensive process continues in modified form today, and NPRC staff still handle so-called 'fire-related' cases using these secondary records. The disaster also prompted major changes in federal archival practice, leading to the installation of modern fire suppression systems, improved storage protocols, and a push toward digitizing and duplicating records to prevent a similar single point of failure. The 1973 fire remains a cautionary tale in archival and records management circles, cited frequently as a reason for redundancy, offsite backups, and modern preservation standards protecting vital government and personal records.
