More model informationJapan’s two-stage satellite launcher based on the American Delta rocket, but with a cryogenic second stage, as well as a Japanese inertial guidance system.
The launch vehicle can fly with either 6 or 9 Castor-2 TX-354-3 solid strap-on boosters.
It has flown 9 times between 1986 and 1992, and has, as a result, enjoyed a 100% success rate.
The technology used in the H-I, such as the cryogenic propulsion and guidance, was later exploited in the H-II rocket.
