  • On the 2nd of August 1963, construction crews drove the first steel foundation pile into the Florida bedrock. This single action marked the beginning of a massive undertaking to build what would become the Vehicle Assembly Building. The project required 4,225 pilings to reach solid ground beneath the marshy soil of Merritt Island. Engineers poured concrete foundations that spanned hundreds of feet across the landscape. By 1966, the structure stood complete as a vertical assembly facility for the Apollo program. NASA originally called it the Vertical Assembly Building before renaming it in early 1965. The building was designed to stack Saturn V rockets vertically onto mobile launch platforms. It sat south of Jacksonville and north of Miami on the Atlantic coast. Only three bays ever connected to the crawlerway despite initial plans for six. Bay 2 remained largely unused during the Saturn V era until later conversions.

  • Four high bays dominate the north end of the facility with enclosed spaces for stacking rocket stages. Each bay features doors standing tall enough to swallow entire shuttle orbiters whole. These massive doors comprise seven vertical panels and four horizontal sections taking forty-five minutes to open or close. Five overhead cranes operate inside including two capable of lifting up to 325 tons each. One hundred thirty-six additional lifting devices assist crews in handling heavy components safely. A transfer aisle runs the full length of the building allowing movement between work areas. Components enter through eight low bays on the south side used for storage and preparation. Air conditioning systems provide ten thousand tons of refrigeration to control moisture levels rather than temperature. Fog can form when large doors open leading to persistent rumors about weather generation inside. When fully assembled a crawler-transporter lifts the platform and moves it toward Launch Complex 39A or 39B.

  • Storm season of 2004 brought Hurricane Frances which blew off 850 aluminum panels from the exterior walls. The storm created new openings covering hundreds of feet across the building sides. Three weeks later Hurricane Jeanne removed another twenty-five panels from the east side. Earlier that same year Hurricane Charley caused damage estimated at seven hundred thousand dollars to repair. Some panels were designed as punch-outs to detach during rapid pressure changes from tropical cyclones. This design allows equalization between outside and inside pressures protecting structural integrity. Damage remained visible throughout 2007 despite repairs beginning in early 2007. Special attention focused on restoring the enormous American flag painted on the facility. The flag had been previously repainted in 1998 for NASA's fortieth anniversary celebrations. Work repaired visible wear from years of storms and weathering exposure.

  • In 1976 workers painted an American flag onto the building as part of United States Bicentennial celebrations. It became the largest flag in the world when added to the structure. Each star measured inches across while stripes stretched wide enough to cover multiple lanes. The blue field occupied space equivalent to a regulation basketball court. Workers began restoration efforts in early 2007 to fix damage from decades of storms. The flag and logo had been repainted once before in 1998 marking forty years since NASA formed. Later in 1998 the bicentennial star logo was replaced by the standard NASA insignia. The flag stood tall and wide covering hundreds of feet of exterior wall. It served as both decoration and historical marker during the Apollo era transitions. Some panels detached during hurricanes but the paint itself remained intact through most events.

  • NASA retired the Space Shuttle program in 2011 after decades of service. Plans initially called for renovating the facility to stack Ares I and Ares V launch vehicles. Those plans vanished when Congress cancelled the Constellation program in 2010. Public tours operated briefly starting around 2012 until February 2014 when renovations paused access. The fiscal year 2013 budget allocated one hundred forty-three point seven million dollars for construction facilities supporting future programs. Modifications to Launch Complex 39 began in 2014 including major repairs and code upgrades. These changes prepared the building for the Space Launch System rocket used in the Artemis program. By March 2022 the first SLS rocket assembled inside preparing for the 16th of November 2022 launch. The structure now supports modern missions while retaining its original vertical assembly capabilities. High Bay 2 remains available for potential commercial use despite limited current activity.

  • On the 16th of June 2015 NASA released an announcement seeking interest from private companies. They wanted organizations to use High Bay 2 and other complex facilities for assembling launch vehicles. This move aligned with intentions to make Kennedy Space Center accessible to both government and commercial ventures. On the 21st of April 2016 Orbital ATK won negotiations for High Bay 2 usage rights. Northrop Grumman purchased Orbital ATK in 2019 completing the agreement that August. The lease included a mobile launcher platform for their OmegA launch vehicle. Development of OmegA was cancelled in September 2020 leaving the bay mostly unused. Northrop Grumman stored hardware there until scheduled removal by late September 2020. No modifications were made to the high bay before the cancellation occurred. The space remains available for future commercial integration efforts.

Common questions

When did construction of the Vehicle Assembly Building begin?

Construction crews drove the first steel foundation pile into the Florida bedrock on the 2nd of August 1963. This action marked the official start of building what would become the Vehicle Assembly Building.

What is the purpose of the Vehicle Assembly Building at Kennedy Space Center?

The Vehicle Assembly Building was designed to stack Saturn V rockets vertically onto mobile launch platforms for the Apollo program. It currently supports modern missions while retaining its original vertical assembly capabilities for the Space Launch System rocket.

How many high bays does the Vehicle Assembly Building contain and how do they function?

Four high bays dominate the north end of the facility with enclosed spaces for stacking rocket stages. Each bay features doors standing tall enough to swallow entire shuttle orbiters whole that comprise seven vertical panels and four horizontal sections taking forty-five minutes to open or close.

What damage did Hurricane Frances cause to the Vehicle Assembly Building in 2004?

Hurricane Frances blew off 850 aluminum panels from the exterior walls creating new openings covering hundreds of feet across the building sides. Storm season of 2004 brought this destruction which left damage visible throughout 2007 despite repairs beginning in early 2007.

When was the American flag painted on the Vehicle Assembly Building and when was it restored?

Workers painted an American flag onto the building as part of United States Bicentennial celebrations in 1976. Workers began restoration efforts in early 2007 to fix damage from decades of storms after the flag had been previously repainted in 1998 for NASA's fortieth anniversary celebrations.
