came under the Naval Sea Systems Command that was established from the merger of the Naval Ordnance Systems Command and Naval Ship Systems Command. Shortly after in 1975, Crane's name was changed to the Naval Weapons Support Center which more accurately reflected the true function of the installation. In 1977, a major change occurred with the designation of the United States Army as the single-service manager of conventional ammunition. This resulted in the establishment of the tenant command, Crane Army Ammunition Activity (CAAA) which took over the loading, assembly, and storage of ammunition at the installation. CAAA and Crane's strong partnership continues today. In 1992, Crane's name was changed to the Crane Division, Naval Surface Warfare Center when the warfare centers were established under the related systems commands. Today, grown from its ordnance roots, Crane is recognized worldwide as a modern and sophisticated leader in diverse and highly technical product lines. In 2005, the Base Realignment and Closure Commission recommended to retain most existing operations at Crane, with weapons and armaments research, development and acquisition, and test and evaluation, but moving gun/ammunition, combat system security, and energetic materials to Naval Air Weapons Station China Lake. This BRAC change resulted in a net loss of 672 civilian jobs from the base. NSA Crane tenants Naval Support Activity Crane hosts a number of different commands and divisions.
