The museum is located on the grounds of the former Kelly Air Force Base, which was once the largest industrial employer in San Antonio.
The facility serves as a repository for historical artifacts related to the development of the internet and early computing architectures.
SAMSAT provides specialized exhibits dedicated to the history of the 16th Air Force, the nation's first numbered Air Force dedicated to information warfare.
The collection includes rare prototypes of early automated manufacturing and robotics equipment used in aerospace production.
Area 21 functions as an active laboratory space where local tech startups and research groups often test hardware prototypes.
Many of the items on display were donated by local engineers and former civil servants who worked at Kelly Air Force Base during the Cold War.
SAMSAT Area 21 is a technology and history museum located within the historic Port San Antonio campus, specifically housed in the repurposed Building 171. The museum focuses on the history of technology, cybersecurity, robotics, and the industrial legacy of the former Kelly Air Force Base. It operates under the San Antonio Museum of Science and Technology (SAMSAT) non-profit organization. The facility displays a wide range of artifacts spanning early mechanical computing, telecommunications, and Cold War-era aerospace engineering. Exhibits frequently integrate interactive elements to highlight San Antonio's ongoing development as a hub for cybersecurity and defense technology. The site serves as a STEAM education resource, frequently hosting programs for local students and technology professionals. Visitors can explore displays that trace the evolution of data processing from vacuum tube computers to modern high-performance systems. The museum bridges the gap between historical military logistics and current civilian tech innovation.
