The Vehicle (originally Vertical) Assembly Building, or VAB, at NASA's Kennedy Space Center (KSC) was used to assemble American manned launch vehicles from 1968-2011. At 3,664,883 cubic meters (129,428,000 cubic feet) it is one of the largest buildings in the world by volume.[2] 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.[2]
The VAB is the largest single-story building in the world,[3] was the tallest building in Florida until 1974,[4] and is still the tallest building in the United States outside an urban area.[4]

History [edit]
The VAB, which was completed in 1966, was originally built to allow for the vertical assembly of the Saturn V rocket for the Apollo program and referred to as the "Vertical Assembly Building". When the Space Shuttle program began, it was renamed to the "Vehicle Assembly Building"[5] and used for the shuttle's external fuel tanks and flight hardware, and to mate the Space Shuttle orbiters to their solid rocket boosters and external fuel tanks. Once assembled, the complete Space Shuttle was moved on the Mobile Launcher Platform and Crawler-Transporter to LC-39 Pad A or B.
Construction [edit]
The VAB is 526 feet (160.3 m) tall, 716 feet (218.2 m) long and 518 feet (157.9 m) wide. It covers 8 acres (3 ha), and encloses 129,428,000 cubic feet (3,665,000 m3) of space.[6]
The building has at least 10,000 tons of air conditioning equipment, including 125 ventilators on the roof supported by four large air handlers (four cylindrical structures west of the building) to keep moisture under control. Air in the building can be completely replaced every hour. The interior volume of the building is so vast that it has its own weather, including "rain clouds form[ing] below the ceiling on very humid days",[7] which the moisture reduction systems are designed to minimize.
Located on Florida's Atlantic coast, the building was constructed to withstand hurricanes and tropical storms with a foundation consisting of 30,000 cubic yards of concrete and 4,225 steel rods driven 160 feet into limestone bedrock.
Capabilities [edit]

There are four entries to the bays located inside the building, which are the four largest doors in the world. Each door is 456 feet (139.0 m) high and takes 45 minutes to completely open or close. The north entry that leads to the transfer aisle was widened by 40 feet (12.2 m) to allow entry of the shuttle orbiter. A central slot at the center of the north entry allowed for passage of the orbiter's vertical stabilizer.
To lift the components of the Space Transportation System, the VAB housed five overhead bridge cranes, including 2 capable of lifting 325 tons, and 136 other lifting devices.
Exterior [edit]
The American flag painted on the building was the largest in the world when added in 1976 as part of United States Bicentennial celebrations, along with the star logo of the anniversary, later replaced by the NASA insignia in 1998. It is 209 feet (63.7 m) high, and 110 feet (33.5 m) wide. Each of the stars on the flag is 6 feet (1.83 m) across, the blue field is the size of a regulation basketball court, and each of the stripes is 9 feet (2.74 m) wide, the width of a standard road lane.[8]
Work began in early 2007 to restore the exterior paint on the immense facility. Special attention was paid to the enormous American flag and NASA "meatball" insignia. The work repaired visible damage from years of storms and weathering. The flag and logo had been previously repainted in 1998 for NASA's 40th anniversary.[9]
The most extensive exterior damage occurred during the storm season of 2004, when Hurricane Frances blew off 850 14 × 6 foot aluminum panels from the building, resulting in about 40,000 square feet (3,700 m2) of new openings in the sides.[9][10] Twenty five additional panels were blown off the east side by the winds from Hurricane Jeanne just three weeks later. Earlier in the season, Hurricane Charley caused significant but less serious damage, estimated to cost $700,000. Damage caused by these hurricanes was still visible in 2007. Some of these panels are "punch-outs", designed to detach from the VAB when a large pressure differential is created on the outside vs. the inside. This allows for equalization, and helps protect the structural integrity of the building during rapid changes in pressure such as in tropical cyclones.
The building has been used as a backdrop in several Hollywood movies including Contact, Marooned, and others.
Future [edit]
The Space Shuttle was retired in 2011. The VAB could be used to some extent for assembly and processing of any future vehicles utilizing Launch Complex 39. As of early 2012, NASA is offering tours of the VAB for "a limited time." In the future, the VAB will be used to prepare commercial launch vehicles, and for the use of NASA's new Space Launch System.
The NASA FY2013 budget includes $143.7 million USD for Cost of Facilities (CoF) requirements in support of Exploration programs including Space Launch System (SLS) and Multi-Purpose Crew Vehicle (MPCV). NASA will begin modifying Launch Complex 39 at KSC to support the new SLS. NASA will begin with major repairs, code upgrades and safety improvements to the Launch Control Center, Vehicle Assembly Building (VAB) and the VAB Utility Annex. This initial work will be required to support any launch vehicle operated from Launch Complex 39 and will allow NASA to begin modernizing the facilities, while vehicle specific requirements are being developed.[11]
