Launch Complex 39 (LC-39) was originally built for the Saturn V for the Apollo manned Moon landing program. Since the end of the Apollo program in 1972, LC-39 has been used to launch every NASA human space flight, including Skylab (1973), the Apollo-Soyuz Test Project (1975), and the Space Shuttle program (1981-2011).
Since December 1968, all launch operations have been conducted from launch pads A and B at LC-39. From 1969–1972, LC-39 was the departure point for all six Apollo manned Moon landing missions using the Saturn V, and was used from 1981–2011 for all Space Shuttle launches.
