Delta Scientific, a leading manufacturer of counter-terrorist vehicle control systems, 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 their vehicle access barrier, a 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.
