MENDOCINO CO., 12/12/25 – The U.S. Air Force safely disposed of a World War II–era practice bomb found on private property in southwestern unincorporated Mendocino County on Tuesday, the Air Force said. 

The Mendocino County Sheriff’s Office contacted the Air Force after an object believed to be a military weapon was discovered. 

Federal law requires military explosives teams to respond when a suspected military weapon is found off base and ownership cannot be determined. In this case, the Air Force assisted local authorities with the investigation and disposal.
