The LM-700 is a satellite bus which was built by Lockheed Martin between the mid-1990s and early 2000s. Typically used for low Earth orbit communications satellites, ninety nine were built, all but one for Iridium Satellite LLC. The exception was a technology development satellite for the United States Air Force, which was never launched. In addition, two boilerplate satellites were launched on a test flight of the Chinese Long March 2C rocket.

Overview

Two variants of the LM-700 were built. The ninety eight Iridium satellites used the LM-700A configuration, specialised for communications. Of these ninety five were launched, whilst three were retained as spares. One of the spare satellites is now displayed in the US National Air and Space Museum.

The LM-700B, designed for other missions, was also offered. One was built as the SBIRS-LADS demonstration satellite for the US Air Force's Space Based Infrared System, however its launch was cancelled after the satellite had been completed and delivered to the customer.

The LM-700A Iridium satellites were launched in clusters between 1997 and 2002. Satellites were launched in groups of five on Delta II 7920-10C rockets, groups of seven on Proton-K/DM2 rockets, pairs on the Long March 2C and on the last launch, two satellites on a Rockot. The cancelled SBIRS-LADS satellite would have used an Athena II.

An LM-700A, Iridium 33 was one of the satellites destroyed in the 2009 satellite collision. Most of the Iridium satellites currently in orbit have already exceeded their design life, whilst others are approaching the end of it, however at least enough satellites are still operating to maintain the network, which requires sixty six.

The Kosmos rockets were a series of Soviet and subsequently Russian rockets, derived from the R-12 and R-14 missiles, the best known of which is the Kosmos-3M, which has made over 440 launches. The Kosmos family contained a number of rockets, both carrier rockets and sounding rockets, for orbital and sub-orbital spaceflight respectively. The first variant, the Kosmos-2I, first flew on 27 October 1961. Over 700 Kosmos rockets have been launched overall.

The Long March 3, also known as the Changzheng 3, CZ-3 and LM-3, was a Chinese orbital carrier rocket design. They were all launched from Launch Area 3 at the Xichang Satellite Launch Center. It was a three-stage rocket, and was mostly used to place DFH-2-class communications satellites into geosynchronous transfer orbits. It was complemented and later replaced by the more powerful Long March 3A, which has an improved third stage.

The Long March 4A, also known as the Changzheng 4A, CZ-4A and LM-4A, sometimes misidentified as the Long March 4 due to the lack of any such designated rocket, was a Chinese orbital carrier rocket. It was launched from Launch Area 7 at the Taiyuan Satellite Launch Center. It was a three-stage rocket, used for two launches in 1988 and 1990. On its maiden flight, on 6 September 1988, it placed the FY-1A weather satellite into orbit. On its second, and final, flight it launched another weather satellite, FY-1B.

The NOTS-EV-2 Caleb, also known as NOTS-500, Hi-Hoe and SIP was an expendable launch system, which was later used as a sounding rocket and prototype anti-satellite weapon. It was developed by the United States Navy's Naval Ordnance Test Station (NOTS) as a follow-up to the NOTS-EV-1 Pilot, which had been abandoned following ten launches officially classified as failed missions. Two were launched in July and October 1960, before the cancellation of the project. Following cancellation, two leftover Calebs were used in the Satellite Interceptor Program (SIP), while three more were used as sounding rockets, under the designation Hi-Hoe. These derivatives flew until July 1962, when the Hi-Hoe made its final flight.

The CTS is an upper stage developed by the China Academy of Launch Vehicle Technology (CALT) to improve the performance of the Long March 2C to high LEO missions like SSO. The two stage LM-2 delivers the payload and stage to an elliptical orbit with the desired apogee and the CTS points the stack in the direction of the correct vector and activates the solid rocket motor (SRM) main engine to circularize it. It then dispenses the spacecraft and does a passivisation procedure.
