LM-2C
History

Based on fight proven technology of LM-1 and LM-2, the development of LM- 2C launch vehicle was started in 1970. After its successful fight in 1975, LM-2 was renamed to LM-2C.

With 14 successes out of 14 launches for LEO missions, this launch vehicle was selected by Motorola, Inc. in April 1993 to provide multiple launches for Iridium communications satellites. According to the Iridium launch mission requirement, some necessary modifications were made. Then this launch vehicle was renamed as LM-2C/SD. Twelve (12) Iridium satellites were successfully launched by LM-2C/SD.
