The Vehicle (originally Vertical) Assembly Building, or VAB, at NASA's Kennedy Space Center (KSC) is a building designed to assemble large space vehicles, such as the massive Saturn V and the Space Shuttle. The future Space Launch System (SLS) will also be assembled there. At 3,664,883 cubic meters (129,428,000 cubic feet) it is one of the largest buildings in the world by volume. The building is at Launch Complex 39 at KSC, halfway between Jacksonville and Miami, and due east of Orlando on Merritt Island on the Atlantic coast of Florida.
