Port San Antonio

Port San Antonio is a multi-purpose, 1,900-acre (7.7 km2) facility in San Antonio, Texas, USA established to serve as an aerospace complex, international airport and industrial hub with two railroads and close access to three interstate highways. Established at the former site of Kelly Air Force Base, the 1,900-acre (7.7 km2) facility is centrally located between the coasts of the United States and along the NASCO corridor between Canada and Mexico. Port San Antonio enjoys designation as a Foreign Trade Zone (#80-10).

Originally established in 1995 by the San Antonio City Council as the Greater Kelly Development Authority, it was re-established under its current name in 2007. Its tenants include such companies as The Boeing Company, Lockheed Martin, Pratt & Whitney, CDI Technology Services, and Standard Aero. Currently in the planning stage is a Town Center project at the port's center which would offer office space as well as provide retail, dining and housing options.

According to a 2010 study, the 13 aerospace companies operating out of the Port were found to have accounted for $1.46 billion in annual economic activity for the region.
