The OTRAG rocket was a modular satellite-delivery rocket developed by the OTRAG company in the 1970s and 80s.[1][2][3] The OTRAG rocket was to become a rocket built up from several mass-produced units, intended to carry satellites with a weight of 1-10 tons or more into orbit. Mass production meant that the vehicle was projected to have been 10x cheaper than conventional vehicles of similar capability.
