Divers assigned to the Explosive Ordnance Disposal Divisions of Naval Submarine Base Kings Bay and Naval Station Mayport prepare to dive into the Ogeechee River in search of old ordnance. Local residents have been finding the 2.75-inch rockets in the river near a popular boat ramp and swimming area. A six-man diving team will use sonar to do a detailed sweep of the river bottom where the forty-year-old rockets have been found.
