Launch Complex 12 or LC-12 at the Cape Canaveral Air Force Station is a launch pad which was used by Atlas rockets and missiles between 1958 and 1967. It is the second most southern of the pads known as missile row, between LC-11 to the South and LC-13 to the North. Along with Complexes 11, 13 and 14, featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time.

  • Launch Complex 12 or LC-12 at the Cape Canaveral Air Force Station is a launch pad which was used by Atlas rockets and missiles between 1958 and 1967. It is the second most southern of the pads known as missile row, between LC-11 to the South and LC-13 to the North. Along with Complexes 11, 13 and 14, featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a 6 metres (20 ft) tall concrete launch pedestal, and a reinforced blockhouse. The rockets were delivered to the launch pad by means of a ramp on the Southwest side of the launch pedestal. Atlas A, C and D missiles were tested from the site. It was also used for orbital launches of Atlas-Able and later Atlas-Agena rockets, and two Project FIRE suborbital tests for Project Apollo, using Atlas D rockets. On 24 September 1959, the first Atlas-Able, 9C, exploded during a static firing test at LC-12, after a turbopump on one of the engines failed triggering a complete engine shutdown. The damaged turbopump continued to allow oxidizer to flow, feeding the fire beneath the vehicle. About a minute later the rocket suffered a structural failure, collapsed and exploded. Damage from the explosion took seven months to repair, with the next launch from the complex occuring in May 1960. In 1961, LC-12 was converted to support the Atlas-Agena rocket. The first Atlas-Agena launch from LC-12 was in August 1961. On 23 April 1962, Atlas-Agena B 133D launched Ranger 4, the first American spacecraft to reach the surface of the Moon, when it made a hard landing at an impact speed of 9,617 kilometres per hour (5,976 mph). On 27 August 1962, Mariner 2 was launched by Atlas-Agena B 179D. It later became the first spacecraft conduct a successful flyby of another planet, when it flew past Venus on 14 December 1962. On 28 July 1964, Atlas-Agena B 250D launched Ranger 7, which was the first fully successful Ranger mission. On 28 November 1964, Atlas-Agena D 288D launched with Mariner 4, which provided the first close-up pictures of Mars. In 1967, LC-12 became the third of the four Atlas pads to be deactivated. Following deactivation, the launch tower, Mobile Service Structure and launch support equipment were dismantled, and the site is no longer maintained.
  • Cape Canaveral AFS Launch Complex 12 (LC-12) ist eine nicht mehr genutzte Startrampe der Cape Canaveral Air Force Station auf Merritt Island, Cape Canaveral in Florida, USA. Sie wurde vom Ende der 1950er bis Ende der 1960er Jahre hauptsächlich zu Starts für Test- und Entwicklungsflüge der Atlas-Interkontinentalrakete genutzt. Auch von der NASA wurden von LC-12 verschiedenste Nutzlasten gestartet. So wurden zwei der frühen Pioneer-Mondsonden sowie alle Ranger-Mondsonden von hier gestartet. Auch drei Mariner-Sonden wurde von LC-10 gestartet. 1967 wurde LC-12 zusammen mit den Geschwisterstartrampen LC-11 und LC-14 offiziell stillgelegt.
