The Titan IIIA or Titan 3A was an American expendable launch system,launched four times in 1964 and 1965,to test the Transtage upper stage which was intended for use on the larger Titan IIIC. The Transtage was mounted atop two core stages derived from the Titan II. The Titan IIIA was also used as the core of the Titan IIIC.
Part of the Titan rocket family,the Titan IIIA made its first flight on 1 September 1964. However,the Transtage failed to pressurize,resulting in a premature cutoff and failure to reach orbit.A second test on 10 December was successful. Two further launches occurred in 1965 with Lincoln Experimental Satellites,before the Titan IIIA was retired.

Titan was a family of United States expendable rockets used between 1959 and 2005. The Titan I and Titan II were part of the US Air Force's intercontinental ballistic missile (ICBM) fleet until 1987. The space launch vehicle versions contributed the majority of the 368 Titan launches, including all the Project Gemini crewed flights of the mid-1960s. Titan vehicles were also used to lift US military payloads as well as civilian agency reconnaissance satellites and to send interplanetary scientific probes throughout the Solar System.
The Titan IIIC was an expendable launch system used by the United States Air Force from 1965 until 1982. It was the first Titan booster to feature large solid rocket motors and was planned to be used as a launcher for the Dyna-Soar, though the spaceplane was cancelled before it could fly. The majority of the launcher's payloads were DoD satellites, for military communications and early warning, though one flight (ATS-6) was performed by NASA. The Titan IIIC was launched exclusively from Cape Canaveral while its sibling, the Titan IIID, was launched only from Vandenberg AFB.
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 2020, the site is used by United Launch Alliance (ULA) for Atlas V launches. Previously, it had been used by the USAF for Titan III and Titan IV launches.
The Inertial Upper Stage (IUS), originally designated the Interim Upper Stage, was a two-stage, solid-fueled space launch system developed by Boeing for the United States Air Force beginning in 1976 for raising payloads from low Earth orbit to higher orbits or interplanetary trajectories following launch aboard a Titan 34D or Titan IV rocket as its upper stage, or from the payload bay of the Space Shuttle as a space tug.
Space Launch Complex 40 (SLC-40), sometimes pronounced Slick Forty and previously Launch Complex 40 (LC-40) is a launch pad for rockets located at the north end of Cape Canaveral Space Force Station, Florida.
This comparison of orbital launch systems lists the attributes of all individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or in development as of 2023; a second list includes all upcoming rockets and a third list includes all retired rockets For the simple list of all conventional launcher families, see: Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems.
Transtage, given the United States Air Force designation SSB-10A, was an American upper stage used on Titan III rockets, developed by Martin Marietta and Aerojet.
The AJ10 is a hypergolic rocket engine manufactured by Aerojet Rocketdyne. It has been used to propel the upper stages of several launch vehicles, including the Delta II and Titan III. Variants were and are used as the service propulsion engine for the Apollo command and service module, in the Space Shuttle Orbital Maneuvering System, and on the European Service Module – part of NASA's Orion spacecraft.
The NOTS-EV-1 Pilot, better known as NOTSNIK was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS). NOTSNIK began as an in-house project using available NOTS funds. The Advanced Research Projects Agency later supplied some funds for the program. The program involved creating transistorized sensors to detect nuclear explosions from the Operation Argus tests. Ten were launched during July and August 1958, all of which failed. It was the first air-launched rocket to be used for an orbital launch attempt; however, none was recorded as having reached orbit. Following the third orbital launch attempt a NOTS engineer at the tracking station in Christchurch, New Zealand reported receiving a weak signal from the spacecraft; This was never confirmed, and the launches were not catalogued as having reached orbit. The Pilot rocket was part of Project Pilot.
The Titan IIID or Titan 3D was an American expendable launch system, part of the Titan rocket family. Titan IIID was flown 22 times with KH-9 and KH-11 satellites between 1971 and 1982, all successful launches. Essentially a Titan IIIC with the Transstage removed, it was designed for heavy LEO payloads.
The Titan II GLV or Gemini-Titan II was an American expendable launch system derived from the Titan II missile, which was used to launch twelve Gemini missions for NASA between 1964 and 1966. Two uncrewed launches followed by ten crewed ones were conducted from Launch Complex 19 at the Cape Canaveral Air Force Station, starting with Gemini 1 on April 8, 1964.
OPS 0855, also designated OV4-3, was an American boilerplate Manned Orbiting Laboratory spacecraft launched in 1966. It was flown to demonstrate the launch configuration for future MOL missions. A number of research payloads, designated Manifold, were carried on board, which were intended to operate for 75 days. However, the spacecraft ceased operations after just 30 days. It was built from a decommissioned HGM-25A Titan I first stage oxidizer tank, bolted to a Transtage. It was part of the MOL and Orbiting Vehicle projects.
OSCAR IV was the fourth amateur radio satellite launched by Project OSCAR and the first targeted for Geostationary orbit on 12 December 1965. The satellite was launched piggyback with three United States Air Force satellites on a Titan IIIC launch vehicle. Due to a booster failure, OSCAR 4 was placed in an unplanned and largely unusable Geostationary transfer orbit.
The Gorgon III – given the military designations KA3N, KU3N, CTV-N-6 and RTV-N-4 – was a rocket-powered air-to-air missile developed by the United States Navy near the end of World War II. With the end of the war, the program was changed to that of a research vehicle for missile control systems; both single and twin-rocket-powered versions were built and tested.
Orbiting Vehicle 2-1, the first satellite of the second series of the United States Air Force's Orbiting Vehicle program, was an American life science research satellite. Its purpose was to determine the extent of the threat posed to astronauts by the Van Allen radiation belts. Launched 15 October 1965, the mission resulted in failure when the upper stage of OV2-1's Titan IIIC booster broke up.
Orbiting Vehicle 2-3, the second satellite of the second series of the United States Air Force's Orbiting Vehicle program, was an American solar astronomy, geomagnetic and particle science research satellite. Launched 22 December 1965 along with three other satellites, the mission resulted in failure when the spacecraft failed to separate from the upper stage of its Titan IIIC.
Lincoln Experimental Satellite 3, also known as LES-3, was a communications satellite, the third of nine in the Lincoln Experimental Satellite. Launched by the United States Air Force (USAF) on 21 Dec 1965, it was stranded in a Geostationary Transfer Orbit rather than its planned circular high orbit. Despite this, LES-3 returned good data on communications propagation in the UHF band.
The Initial Defense Communications Satellite Program or IDCSP was the first United States Department of Defense communications satellite constellation and the first stage of the Defense Communications Satellite Program (DCSP). Launched in five groups by Titan IIIC launch vehicles to near equatorial, subsynchronous orbits between 1966 and 1968, they were intended to be experimental testbeds. They were so successful that, by the time of the launch of the last set of eight satellites, the IDCSP was deemed operational and renamed Initial Defense Satellite Communications System or IDSCS. This system allowed real-time collection of battlefield intelligence during the Vietnam War. A total of 35 IDCSP satellites were launched, 27 successfully.
Orbiting Vehicle 2-5, the third and last satellite of the second series of the United States Air Force's Orbiting Vehicle program, was an American particle science and ionosphere research satellite. Launched 26 September 1968 along with three other satellites, OV2-5 became the first scientific satellite to operate at geosynchronous altitude.
Orbiting Vehicle 1-6 was launched via Titan IIIC rocket into orbit 2 November 1966 along with two other satellites in the United States Air Force's Orbiting Vehicle series on the first and only Manned Orbiting Laboratory test flight. The eighth satellite in the OV1 series to be launched, OV1-6 was designed to release a number of inflatable spheres, which would then be used in classified tracking experiments conducted on the ground. It is uncertain whether or not the satellite successfully released any of its spheres. OV1-6 reentered the Earth's atmosphere on 31 December 1966.
