How ULA's 2.4 million-square-foot Alabama plant builds the Vulcan rocket

National Security Editor Guy Taylor sits down with Dan Caughran, Senior Vice President of Production Operations, and Gary Wentz, Vice President of Atlas and Vulcan Programs, for a rare look at how the Vulcan Centaur rocket comes together -- from national security payloads to a $5 billion economic footprint in North Alabama. This project is sponsored by ULA.
