These Formerly Used Defense Sites (FUDS) are the locations from which military activity occurred and the various trajectory and ranges from these areas where weapons were deployed or tested. Therefore, this dataset acts as a possible proxy for Unexploded Ordinances (UXOs) or hazardous material locations. UXOs are explosive weapons (bombs, bullets, shells, grenades, mines, etc.) that did not explode when they were employed and still pose a risk of detonation. Two related datasets that should be viewed in tandem are Unexploded Ordnance Areas displays known or possible former explosive dumping areas and Unexploded Ordnance Locations displays known or possible individual or tightly grouped unexploded ordnances on the ocean floor.
