NASA Vehicle Assembly Building
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 VAB is the largest single-story building in the world, was the tallest building (160.3 m) in Florida until 1974, and is still the tallest building in the United States outside an urban area.
