ResumoOn February 4th 1994, the maiden flight of H-II rocket was successfully conducted. With the completion of H-II development work, Japan has eventually got a world level spacecraft launching capability and both 1000 and 100kN thrust class LOX/LH2 engines, LE-7 and LE-5A. H-II will be a work-horse rocket for Japan's near-term future space activities. A number of studies for improving vehicle launching capability and further cost reduction are under considerations, with regard to Upgraded H-II rocket; H-IIA rocket which will be launched on 1st February 2000. The LE-7A and LE-5B are key components of the H-IIA propulsion system and also the main subject of study in these improvement plans. This paper overviews the current status of LE-7A and LE-5B according to the H-IIA configurations.
