A man without credentials tried to gain access Wednesday to the San Diego campus known to many San Diegans as Space and Naval Warfare Systems (SPAWAR).
After the man's car was stopped on Pacific Highway at around 6 a.m., military officials said they found strange wiring connecting the vehicle's engine compartment to the passenger area of the vehicle.
San Diego police officers closed down southbound lanes at Kurtz with northbound lanes at Barnett, officials said. Eastbound Enterprise was also closed at Jessop.
Military explosive ordnance experts were called in to investigate the suspected explosive device. They determined there was no threat.
The driver was taken into custody and transferred to San Diego County Mental Health for evaluation.
Pacific Highway was reopened to traffic before 8 a.m.
Naval Base Point Loma posted an update to its official Facebook page reporting the issue is a suspicious person attempting to enter the Old Town complex.
"Request all personnel remain clear of the main gate while Security investigates the suspect vehicle," the base's post stated.
However, after 8 a.m., employees were no longer required to shelter in place and the main gate was reopened.
Now known as Naval Information Warfare Systems Command or NAVWAR, the facility and its staff develop, deliver, and sustain communications and information warfare capabilities for the U.S. Navy as well as support U.S Marine Corps, U.S. Air Force, U.S. Army and U.S. Goast Guard programs.
The system center in San Diego formally changed its name to Naval Information Warfare Center Pacific in February.
