It was used for ten test launches of SM-64 Navaho missiles. The Navaho was a supersonic nuclear-armed cruise missile. In addition to LC-9, Navaho tests were also conducted at LC-10 and Edwards Air Force Base. The Navaho was cancelled after poor performance in testing, eight of the eleven test launches of the final prototype failed. All of the failed launches were conducted from LC-9. As of 2011, the concrete launch structure is still standing, but is not maintained; and the launch support equipment has been removed. The site is not accessible to the general public.
