GX (JAXA)
This is a NASDA sponsored project to replace the J-1 launcher, which has been proved to be too expensive. The GX rocket will be developed by an industry joint venture named Galaxy Express, consisting of Ishikawajima-Harima Heavy Industries (IHI) and Mitsubishi Heavy Industries. The first stage will consist of an Atlas-3 body with a russian RD-180 engine (Kerosene / LOX). The second stage will feature a new developed liquid fuel engine (Liquid Natural Gas / LOX).
