In response to the early Soviet successes, the United States built up a major spaceport complex at Cape Canaveral in Florida. A large number of unmanned flights, as well as the early human flights, were carried out at Cape Canaveral Space Force Station. For the Apollo programme, an adjacent spaceport, Kennedy Space Center, was constructed, and achieved the first manned mission to the lunar surface (Apollo 11) in July 1969. It was the base for all Space Shuttle launches and most of their runway landings. For details on the launch complexes of the two spaceports, see List of Cape Canaveral and Merritt Island launch sites.
