GX (rocket)

GX was a design for an expendable launch system intended to compete in the commercial satellite launch sector. The system had developed by Galaxy Express Corporation, a joint venture between IHI Corporation (IHI), the Japan Aerospace Exploration Agency (JAXA), United Launch Alliance (ULA), Lockheed Martin Corporation (LM) and several other Japanese companies.

The GX design uses a two-stage rocket. The first stage would have been the Atlas Common Core Booster, currently used as the first stage of the Atlas V rocket, which would have been provided by United Launch Alliance. The second stage was to be a newly designed stage produced by IHI, using liquefied natural gas as fuel and liquid oxygen as an oxidizer. The GX would have been the only space vehicle to use that combination of fuel and oxidizer.

The Japanese government finally abandoned the GX program in December 2009. Galaxy Express disbanded around March 2010.
