Launch Complex 6 (LC-6) at Cape Canaveral Air Force Station, Florida is a launch site used by Redstone and Jupiter series rockets and missiles. It is on the south end of Cape Canaveral, close to Launch Complex 5, with which it shared a blockhouse. With LC-5, it was the location of the first tests of the mobile launch concept designed by Kurt H. Debus.[citation needed] This concept was revised and improved and eventually used at LC-39 for the Saturn V and Space Shuttle.
