Naval Air Station Fort Worth Joint Reserve Base or NAS Fort Worth JRB, formally Carswell AFB, is a military airfield located five miles (8 km) west of the central business district of Fort Worth, Texas.

The base, which is under the operational oversight of the Commander, Navy Installations Command, is a joint defense facility which plays a pivotal role in the training and equipping of air crews and aviation ground support personnel. The Fort Worth "joint team" ensures military Reservists and Guardsmen receive quality training in preparation for mobilization readiness, its primary purpose being to ensure the defense readiness of America.

Several Navy headquarters and operational units are based at NAS Fort Worth JRB, including two aviation squadrons, intelligence commands and Seabees. The Air Force Reserve Command's Tenth Air Force headquarters and the 301st Air Force Fighter Wing are based at the installation, as well as the 136th Airlift Wing of the Texas Air National Guard. The 14th Marine Regiment, the 8th Marine District and Marine Air Group 41, along with a Marine F/A-18 and KC-130 squadron call NAS Fort Worth JRB home. Army aviaiton units are the most recent additions to the installation.

The base's runway is also used by Lockheed Martin Aeronautics, as their large Fort Worth assembly facility (where the F-16 Fighting Falcon, Mitsubishi F-2, F-22A Raptor, and the F-35 Lightning II are built) is located adjacent to the base.

With such a large facility, there are approximately 4,000 full time military and civilian employees, along with another 7,000 Reservists and Guardsmen stationed at the base, security is a key consideration. Controlling access to and within the base therefore is critical and to address these requirements NAS Fort Worth turned to SALTO Systems, a leading global provider of advanced technology access control solutions.

Mission

With military facilities across the US remaining on high alert due to the on-going terrorist threat, protecting the base and its associated support structure and housing complex is a critical mission. To achieve this, the base employs a multilayered security measures approach beginning with perimeter protection and moving inwards to the core facilities. This creates a much stronger overall security system

As part of the on-going process to continually monitor, review and improve this system the Naval Air Station recently received federal funding to upgrade the access control capabilities at its base housing complex, and replace the outdated magstripe locks with new wireless electronic smart locks.
