Boeing Huntington Beach is home to many of the company’s astronautic programs. Located on the east side of the Seal Beach Weapons Station, the Huntington Beach campus was acquired by Boeing when it merged with McDonnell Douglas in 1997. Though it has shrunk since the 1990s, this site was involved in many major aerospace programs, including the production of the Saturn V rocket, the Delta rocket, the Space Shuttle, Skylab, and the International Space Station. It was also used for developing hypersonic scramjet aircraft, including the X-51A, an unmanned experimental aircraft that, in 2013, flew at more then five times the speed of sound (3,400 miles per hour), before burning all its fuel and plunging into the ocean off Point Mugu.
