Residents of Old Stage Road in Gualala got a first-hand lesson in military history on Tuesday, December 9, when a World War II–era practice bomb exploded at Ocean Ridge Airport.

The device was detonated by the Beale Air Force Base Explosive Ordnance Disposal (EOD) team, which responded after a possible explosive device was reported near 38000 Sedalia Drive.

According to an account published by Beale Air Force Base, the object was identified as a World War II AN-MK 23 practice bomb containing explosive material.

A document published by the U.S. Army Corps of Engineers states that these bombs were used for low-altitude horizontal or dive-bombing practice.

The EOD team removed the device to a “remote location,” identified as Ocean Ridge Airport, where it was destroyed in a controlled detonation using C-4 explosives.

The Independent Coast Observer said the detonation was heard and felt on neighboring Old Stage Road.

South Coast Fire Protection District Chief Jason Warner told the Independent Coast Observer that the explosion caused no damage to buildings or property.
