Mu-3D

M-3D

Mission Profile

Mu-3D was a three-stage solid-propellant launch vehicle developed by Japan's Institute of Space and Aeronautical Science (ISAS) as part of the indigenous Mu rocket series, which formed the backbone of Japan's early scientific space program. Measuring 23.6 meters in length and weighing 43,600 kg at launch, it generated 1,060 kN of thrust and first flew in August 1969. The Mu-3D represented a significant step in Japan's development of homegrown solid-rocket launch technology, providing the capability to orbit small scientific payloads without reliance on foreign vehicles. Its heritage fed directly into subsequent Mu variants and ultimately Japan's M-V rocket, one of the world's most capable solid-fuel orbital launchers.
