The Vertical Integration Building was a building at Cape Canaveral Air Force Station (CCAFS) in Florida, located at the far south end of the industrial area supporting SLC-40 and SLC-41. The building was used to support Titan III and Titan IV launches. These expendable launch systems were operated by the United States Air Force, both at CCAFS and at Vandenberg Air Force Base in California from 1965 to 2005. Several Titan rockets could be vertically integrated at the same time inside the Vertical Integration Building. In that respect it was a precursor to the Vehicle Assembly Building used for the Saturn V and Space Shuttle.
