Saturn V Dynamic Test Stand, also known as Dynamic Structural Test Facility, at the George C. Marshall Space Flight Center in Huntsville, Alabama is the test stand used for testing of the Saturn V rocket and the Space Shuttle prior to the vehicles' first flights. Designated building 4550,[1] it stands 363 feet (Template:Convert/round m) tall and is 98 feet (Template:Convert/round m) square.[2] NASA built the test stand in 1964 to conduct mechanical and vibrational tests on the fully assembled Saturn V rocket. Major problems capable of causing failure of the vehicle were discovered and corrected here.[3]
It was declared a National Historic Landmark in 1985.[3][1]
