Delta Scientific announced that, on June 3, 2019, when a man couldn’t produce credentials at Mayport Naval Station, he gunned his engine and attempted to enter. The security staff activated Delta DSC501 to pop out of the ground. The vehicle crashed into it and was brought to a standstill. The violator was taken to the hospital and died two days later. Eight days later, on June 11, a man, driving a Ford F-350 truck, also tried to get on base.
