World War II
Of the 16 million Americans who served in WWII, more than 400,000 died during the war. At the end of the war, there were approximately 79,000 Americans unaccounted for. This number included those buried with honor as unknowns, officially buried at sea, lost at sea, and missing in action.
Today, more than 73,000 Americans remain unaccounted for from WWII.
At war's end, American casualties remained unaccounted-for around the globe, some where they had fallen, some in the depths of the oceans, and many in temporary cemeteries scattered throughout the major theaters.
Following the war, the U.S. Government launched a global initiative called, "The Return of the World War II Dead Program," to locate aircraft crash sites, comb former battlefields for isolated graves, and disinter temporary military cemeteries around the globe. The U.S. Army, as the responsible service, created the American Graves Registration Service (AGRS) to perform this task. Once remains had been recovered, they were transported to Central Identification Laboratories, where technicians confirmed or established identifications of more than 280,000 individuals. The identified service members were then buried in accordance with the wishes of their next of kin. The program operated from 1945 to 1951, working until all known leads were exhausted. The Army program was a worldwide endeavor employing approximately 13,000 personnel, and costing $163.8 million in wartime dollars.
After the end of the official program for returning the dead of WWII, the U.S. Army Mortuary system continued to recover and identify smaller numbers of WWII service members. These identifications stemmed largely from reports of remains discovered by the citizens of the countries where the casualties occurred. Upon receipt of such a report, a mortuary team would investigate, recover and identify the remains. As a result, more than 200 additional service men were identified between 1951 and 1976.
After 1976, the task of recovering and identifying the remains of WWII service members fell largely to the U.S. Army Central Identification Laboratory in Hawaii (CILHI). From 1976 to 2003 that organization sent recovery teams to the field using anthropologists and odontologists to identify an additional 346 individuals. In 2003, CILHI merged with Joint Task Force-Full Accounting to form the Joint POW/MIA Accounting Command (JPAC). JPAC, still in operation today, has accounted for an additional 300 service members and continues to increase their capacity to investigate the cases of unrecovered WWII service members.
In 2003, historians at the Defense POW/Missing Personnel Office began developing a comprehensive database of WWII service members whose remains were not recovered or identified after the war. This database was a significant step in creating a comprehensive plan to research WWII missing personnel.
In January 2010, following passage of NDAA 2010, DPMO added a field investigation mission to the WWII Division (formerly the Archival Research branch). Historians and analysts at DPMO collaborate with JPAC in researching, investigating and nominating for recovery the cases of U.S. casualties still missing from WWII.
