J-I

TheJ-I was asolid-fuel, expendable,small-lift launch vehicle developed by theNational Space Development Agency of Japan and theInstitute of Space and Astronautical Science. In an attempt to reduce development costs, it used thesolid rocket booster from theH-II as the first stage, and the upper stages of theM-3SII.[1] It flew only once on a suborbital flight taking place on 11 February 1996 from theOsaki Launch Complex at theTanegashima Space Center in a partial configuration, to launch the demonstratorHYFLEX. The vehicle never flew in the final orbital capability configuration, which should have launched theOICETS satellite (OICETS was launched on a RussianR-36MUTTHIntercontinental ballistic missile-basedDnepr rocket instead).

On the HYFLEX mission a load of 1,054 kg was launched 1,300 km downrange. Apogee was 110km; the HYFLEX payload achieved speed of approximately 3.8 km/s.
