List of Delta IV launches

Last updated

Delta IV was a group of five expendable launch systems in the Delta rocket family introduced in the early 2000s. Originally designed by Boeing's Defense, Space and Security division for the Evolved Expendable Launch Vehicle (EELV) program, the Delta IV became a United Launch Alliance (ULA) product in 2006. The Delta IV was primarily a launch vehicle for United States Air Force (USAF) military payloads, but was also used to launch a number of United States government non-military payloads and a single commercial satellite. [1]

Contents

The Delta IV originally had two main versions which allowed the family to cover a range of payload sizes and masses: the Medium (which had four configurations) and Heavy. [2] Since September 2019, only the Heavy remained active, with payloads that would previously fly on Medium moving to either the existing Atlas V or the forthcoming Vulcan. Retirement of the Delta IV occurred in 2024. [3]

Delta IV vehicles were built in the ULA facility in Decatur, Alabama. Final assembly was completed at the launch site by ULA: at the horizontal integration facility for launches from SLC-37B pad at Cape Canaveral and in a similar facility for launches from SLC-6 pad at Vandenberg Air Force Base.

Atlas V is an expendable launch system and the fifth major version in the Atlas launch vehicle family. It was designed by Lockheed Martin and has been operated by United Launch Alliance (ULA) since 2006. It is used for DoD, NASA, and commercial payloads. It is America's longest-serving active rocket. After 87 launches, in August 2021 ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. As of June 2024, 16 launches remain. Production ceased in 2024. Other future ULA launches will use the Vulcan Centaur rocket.

Space Launch Complex 37 (SLC-37), previously Launch Complex 37 (LC-37), is a launch complex on Cape Canaveral Space Force Station, Florida. Construction began in 1959 and the site was accepted by NASA to support the Saturn I program in 1963. The complex consists of two launch pads. LC-37A has never been used, but LC-37B launched uncrewed Saturn I flights and was modified and launched Saturn IB flights, including the first (uncrewed) test of the Apollo Lunar Module in space. It was deactivated in 1972. In 2001 it was modified as the launch site for Delta IV, a launch system operated by United Launch Alliance.
