About H-II
The H-II rocket was a Japanese satellite launch system which flew seven times between 1994 and 1999 with 5 successes. It was developed by NASDA in order to give Japan a capability to launch larger satellites in the 1990s. It was the first two stage liquid fuelled rocket Japan made using only domestic technologies.
