St. Julien's Creek Annex (SJCA) is a U.S. naval support facility that provides administrative offices, light industrial shops, and storage facilities for tenant naval commands. Its primary mission is to provide a radar testing range (35 acres or 141,640 m2) and various administrative and warehousing structures for the Norfolk Naval Station.
St. Julien's Creek Annex occupies approximately 590 acres (1,982,960 m2) located in southeastern Virginia at the confluence of St. Julien's Creek and the Southern Branch Elizabeth River in the city of Chesapeake, Virginia. The northern boundary of the annex is the boundary between the cities of Portsmouth and Chesapeake, Virginia. The Elizabeth River and St. Julien's Creek form its eastern and southern boundaries, respectively, of the annex. Norfolk Naval Shipyard is located less than one mile (1.6 km) to the north.
The St. Julien's Creek Annex began operations in 1849 as an ordnance and material storage facility. In 1898, the facility was equipped for assembling ammunition, and until 1970, supplied ammunition to the fleet in addition to loading, assembling, issuing, and receiving naval gun ammunition, and conducting experimental and test loading for new ammunition.
In 1969, St. Julien's Creek was disestablished under U.S. Department of Defense and was consolidated as an annex to the Naval Weapons Station at Yorktown, Virginia. Ordnance operations at the facility were terminated in the 1970s.
