This is a 1:15 scale model of the H-II, the fourth rocket built by Japan's National Space Development Agency (NASDA). The H-II had liquid-fuel engines on both its first and second stages and two strap-on solid-fuel rockets to increase boost at liftoff. It was the first NASDA rocket to use exclusively Japanese technology. NASDA first successfully launched the H-II in 1994, placing one satellite into Earth orbit and one experimental vehicle that returned to Earth after one orbit. Over the next five years, NASDA successfully launched H-IIs on four of six attempts. The larger and more powerful H-IIA, which first flew in 2002, replaced the H-II. NASDA built this model and donated it to NASM in 1991.
