A 1,000-pound bomb made during World War II and used to break through dams and bridges has been unearthed at the Brooksville-Tampa Bay Regional Airport in Florida.

The Hernando County Sheriff’s Office received a call Tuesday from a construction company working to build a technical college at the airport after workers found a bomb, Hernando County Sheriff Al Nienhuis said in a video posted to Facebook.

The bomb was determined to be an M-65, a general purpose explosive used in World War II and the Korean War “against reinforced targets like dams and concrete or steel railroad bridges,” according to the National Museum of the United States Air Force.

The sheriff’s office could not tell whether the bomb was live or inert, and evacuated within a half-mile radius of the device, Sheriff Nienhuis said.

The Citrus County Bomb Squad determined the bomb was inert, the sheriff’s office wrote in an update on Facebook, resulting in the lifting of the evacuation order.

A team from MacDill Air Force Base in Tampa helped to dispose of the bomb.
