Brooks Air Force Base is a closed United States Air Force facility, located in San Antonio, Texas. It was closed on 30 September 2011. In 2002 Brooks Air Force Base was renamed Brooks City-Base when the property was conveyed to the Brooks Development Authority as part of a unique project between local, state, and federal government. The Brooks Development Authority is now the owner and operator of the property, and is redeveloping it as a science, business, and technology center. The Air Force was the largest tenant at Brooks City-Base.
