Launch Complex 11 (LC-11) at Cape Canaveral Space Force Station, Florida, is a launch complex used by Atlas missiles between 1958 and 1964. It is the southernmost of the launch pads known as Missile Row. When it was built, it, along with complexes 12, 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 concrete launch pedestal that was 6 metres (20 ft) tall and a reinforced blockhouse. The rockets were delivered to the launch pad by a ramp on the southwest side of the launch pedestal.
Thirty-two Atlas B, D, E and F missiles were launched on suborbital test flights from LC-11. The first launch to use the complex was Atlas 3B, the first flight of a complete Atlas, which was launched on 19 July 1958. In addition to the suborbital tests, one orbital launch was conducted from the complex. On 18 December 1958, Atlas 10B launched SCORE, the world's first communications satellite, into low Earth orbit.
The area of LC-11 is currently leased to Blue Origin. [1]
Two on-pad explosions occurred on LC-11. The first was Missile 48D in April 1960, which suffered combustion instability and exploded on the pad. Although no specific cause for the combustion instability could be determined, the separate duct for the booster turbine exhaust had been removed from the Atlas pads at CCAS earlier in the year since it was considered unnecessary and complicated ground testing of the missiles. The failure occurred slightly under a month after Missile 51D had exploded on LC-13 due to combustion instability, and after these back-to-back failures, it was decided to put the exhaust duct back on the pads. Although there was no evidence indicating that the lack of the exhaust ducts caused the failures, program officials decided to play it safe, and in any case wanted the pads to conform with Atlas D silo configurations.
The second explosion on LC-11 was when Missile 11F blew up one second after liftoff in April 9, 1962 due to a turbopump failure. In both causes, pad damage was relatively light and LC-11 restored to use in two months.
Following the end of Atlas testing at Cape Canaveral, LC-11 was the only one of the four Atlas pads to not be used for space launches, and hence was first of the four pads to be deactivated. Following deactivation, the mobile service tower and support equipment were dismantled, and the site was unmaintained for over 50 years.
Blue Origin has leased the site to redevelop it for their use. [2] On March 29, 2017, it was reported that Blue Origin has chosen LC-11 to conduct test firings of the BE-4 engine. LC-11 is located near Spaceport Florida Launch Complex 36, which will support launches of Blue Origin's New Glenn Launch Vehicle, currently scheduled for a launch no-earlier then 2020. [3] Throughout 2017, aerial / satellite imagery from Planet Explorer showed that construction of a new facility was underway there. [4] In 2019 aerial photos showed a complete test stand. The test stands have two bays allow Blue Origin to test two engines at once. [5]

Launch Complex 39A (LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida. The pad, along with Launch Complex 39B, was first constructed in the 1960s to accommodate the Saturn V launch vehicle, and has been used to support NASA crewed space flight missions, including the historic Apollo 11 moon landing and the Space Shuttle. The site is currently leased by SpaceX and supports launches of the Falcon 9 and Falcon Heavy rockets.
The Thor-Able was an American expendable launch system and sounding rocket used for a series of re-entry vehicle tests and satellite launches between 1958 and 1960.
Launch Complex 39 (LC-39) is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, United States. The site and its collection of facilities were originally built as the Apollo program's "Moonport" and later modified for the Space Shuttle program. Launch Complex 39 consists of three launch sub-complexes or "pads"—39A, 39B, and 39C—a Vehicle Assembly Building (VAB), a Crawlerway used by crawler-transporters to carry mobile launcher platforms between the VAB and the pads, Orbiter Processing Facility buildings, a Launch Control Center which contains the firing rooms, a news facility famous for the iconic countdown clock seen in television coverage and photos, and various logistical and operational support buildings.
Space Launch Complex 41 (SLC-41), previously Launch Complex 41 (LC-41), is an active launch site at Cape Canaveral Space Force Station. As of 2024, the site is used by United Launch Alliance (ULA) for Atlas V and Vulcan Centaur launches. Previously, it had been used by the United States Air Force for Titan IIIC, Titan IIIE, and Titan IV launches.
Launch Complex 36 (LC-36) is a launch complex located at the Cape Canaveral Space Force Station in Florida. Historically, it served as a launch pad for Atlas rockets operated by NASA and the U.S. Air Force from 1962 to 2005.
Missile Row was a nickname given in the 1960s to the eight SM-65 Atlas and HGM-25A Titan I launch complexes at the middle area of Cape Canaveral Space Force Station (CCSFS), historically used by the United States Air Force and NASA. Operated by the 45th Space Wing since 1949, it was the site of all fourteen Mercury-Atlas and Gemini launches, as well as many other early missile tests, Department of Defense (DoD) launches, and NASA launches. For the DoD, it played a secondary role to Vandenberg Air Force Base in California, but was the launch site for many NASA unmanned space probes, as those spacecraft were typically launched on military launchers.
The Convair SM-65A Atlas, or Atlas A, was the first full-scale prototype of the Atlas missile, which first flew on 11 June 1957. Unlike later versions of the Atlas missile, the Atlas A did not feature the stage and a half design. Instead, the booster engines were fixed in place, and the sustainer engine was omitted. The propulsion system used on the initial Atlas As was an early version of the Rocketdyne MA-1 engines with conical thrust chambers that produced a mere 135,000 pounds of thrust, compared with the 360,000 pounds of the fully operational Atlas D. Several pieces of hardware found on the operational Atlas were either missing on the A-series or only partially implemented. Powered flight on the A-series would last about two minutes and compared to later Atlases, long pad hold-down times, with up to 11 seconds between engine start and launcher release.
The SM-65D Atlas, or Atlas D, was the first operational version of the U.S. Atlas missile. Atlas D was first used as an intercontinental ballistic missile (ICBM) to deliver a nuclear weapon payload on a suborbital trajectory. It was later developed as a launch vehicle to carry a payload to low Earth orbit on its own, and later to geosynchronous orbit, to the Moon, Venus, or Mars with the Agena or Centaur upper stage.
The SM-65E Atlas, or Atlas-E, was an operational variant of the Atlas missile. It first flew on October 11, 1960, and was deployed as an operational ICBM from September 1961 until April 1966. Following retirement as an ICBM, the Atlas-E, along with the Atlas-F, was refurbished for orbital launches as the Atlas E/F. The last Atlas E/F launch was conducted on March 24, 1995, using a rocket which had originally been built as an Atlas E.
The SM-65F Atlas, or Atlas-F, was the final operational variant of the Atlas missile, only differing from the Atlas E in the launch facility and guidance package used. It first flew on 8 August 1961, and was deployed as an operational ICBM between 1961 and 1966. Following retirement as an ICBM, the Atlas-F, along with the Atlas-E, was refurbished for orbital launches as the Atlas E/F.
Launch Complex 12 (LC-12) at Cape Canaveral Space Force Station, Florida was a launch pad used by Atlas rockets and missiles between 1958 and 1967. It was 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, LC-12 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 concrete launch pedestal that was 6 metres (20 ft) tall 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.
Launch Complex 13 (LC-13) was a launch complex at Cape Canaveral Space Force Station (CCAS), the third-most southerly of the original launch complexes known as Missile Row, lying between LC-12 and LC-14. In 2015, the LC-13 site was leased by SpaceX and was renovated for use as Landing Zone 1 and Landing Zone 2, the company's East Coast landing location for returning Falcon 9 and Falcon Heavy launch vehicle booster stages. It is leased by US Space Force to Phantom Space and Vaya Space who will operate this launch complex after the termination of SpaceX's lease in future.
Launch Complex 16 (LC-16) is a launch pad site located at Cape Canaveral Space Force Station (CCSFS) in Florida. Part of the Missile Row lineup of launch pads, it was built for use by LGM-25 Titan missiles, and later used for NASA operations before being transferred back to the US military and used for tests of MGM-31 Pershing missiles. Six Titan I missiles were launched from the complex between December 1959 and May 1960. These were followed by seven Titan II missiles, starting with the type's maiden flight on March 16, 1962. The last Titan II launch from LC-16 was conducted on May 29, 1963.
Launch Complex 18 (LC-18) is a launch complex at the Cape Canaveral Space Force Station, Florida that was active during the late 1950s and early 1960s. It was used by Viking, Vanguard, Thor and Scout rockets. The complex consists of two launch pads, LC-18A, which was originally built by the US Navy for the Vanguard rocket, and LC-18B, which was originally by the US Air Force used for tests of the PGM-17 Thor missile.
The Atlas LV-3B, Atlas D Mercury Launch Vehicle or Mercury-Atlas Launch Vehicle, was a human-rated expendable launch system used as part of the United States Project Mercury to send astronauts into low Earth orbit. Manufactured by Convair, it was derived from the SM-65D Atlas missile, and was a member of the Atlas family of rockets. With the Atlas having been originally designed as a weapon system, testing and design changes were made to the missile to make it a safe and reliable launch vehicle. After the changes were made and approved, the US launched the LV-3B nine times, four of which had crewed Mercury spacecraft.
New Glenn is a heavy-lift launch vehicle developed by Blue Origin, named after NASA astronaut John Glenn, the first American astronaut to orbit Earth. New Glenn is a two-stage rocket with a diameter of 7 m (23 ft). Its first stage is powered by seven BE-4 engines that are also designed and manufactured by Blue Origin. It is intended to launch from Cape Canaveral Launch Complex 36, with the first stage landing on a barge called Landing Platform Vessel 1. The inaugural vehicle was unveiled on the launch pad in February 2024.
The private aerospace company Blue Origin has a number of development, manufacturing, and test facilities in four US states: Washington, Texas, Florida, and Alabama.
