A bomb threat at Norfolk Naval Shipyard in Portsmouth, Virginia, triggered an emergency response Tuesday, September 29, 2026, after authorities were alerted to a verbal threat inside one of the shipyard’s buildings.
The incident prompted the evacuation of employees working inside Building 510, while other personnel in the shipyard’s industrial area were instructed to shelter in place as security officials investigated the situation.
A suspect was detained following the threat, according to information released by the shipyard and reported by local media.
What Happened at Norfolk Naval Shipyard?
The bomb threat was reported at approximately 1:30 p.m. Tuesday inside Building 510 at the Norfolk Naval Shipyard.
Shipyard law enforcement was notified immediately and detained a suspect in connection with the reported threat.
Employees inside the affected building were evacuated as a precaution. Other personnel located within the shipyard’s industrial area were directed to remain sheltered while authorities assessed the situation.
The available reporting describes the incident as a verbal bomb threat. Authorities had not publicly released detailed information about the nature of the threat or the identity of the person detained at the time of the latest reports.
Building 510 at the Center of the Response
The emergency response centered on Building 510, which is part of the shipyard’s electronics facilities.
Historical information from the shipyard indicates construction on the building began in 1953, with the facility opening in 1956.
The evacuation and shelter-in-place measures were precautionary actions intended to protect personnel while security officials investigated the reported threat.
There has been no verified report in the available coverage indicating that an explosive device was found or that an explosion occurred.
Suspect Detained as Investigation Continues
One person was detained after the threat was reported.
The detention represents the latest confirmed development in the incident, but authorities had not publicly provided a detailed account of what allegedly prompted the threat or whether the individual would face criminal charges.
The investigation remains focused on determining the circumstances surrounding the reported threat and assessing whether any further security concerns exist at the facility.
Evacuation and Shelter-in-Place Measures
The response involved two separate precautionary measures.
Employees inside Building 510 were evacuated, while personnel elsewhere in the industrial area were instructed to shelter in place.
Such measures allow security personnel to isolate an affected location while limiting movement around the broader area during an active investigation.
The Norfolk Naval Shipyard has established emergency procedures for situations requiring evacuation or sheltering. The U.S. Navy has previously explained that evacuation zones and emergency procedures are designed to move personnel away from hazards while reducing congestion during an installation-wide response.
