The H3 Launch Vehicle is a Japanese expendable launch system. H3 launch vehicles are liquid-propellant rockets with strap-on solid rocket boosters and are launched from Tanegashima Space Center in Japan. Mitsubishi Heavy Industries (MHI) and JAXA are responsible for the design, manufacture, and operation of the H3. The H3 is the world's first ...

The 63 m (297 ft) H3 is designed to carry a 6.5 metric ton payload and over the long-term, the agency wants to reduce per-launch cost to as low as five billion yen ($33 million) - half of what an ...
As the successor to Japan’s H-2A and H-2B rockets, the H3 is designed to be more economical by using commercial off-the-shelf products, rather than exclusive aerospace components, according to JAXA.
Developed by JAXA and prime contractor Mitsubishi Heavy Industries, the H3 was meant to replace the two-decade-old H-IIA rocket and reduce per-launch costs by half, to as low as five billion yen ...
When the H–1 was announced in 1986, company representative Tsuguo Tatakawe clarified that it would only be used to launch indigenous (i.e. Japanese) payloads, that only two launches per year could be mounted, and that the launch window consisted of a four-month period in which Japanese fishing fleets were not active (the falling launch boosters may damage fishing nets in the ocean waters).
The rocket appeared to fly as planned, and JAXA is expected to give further details at a news conference later Monday. The launch was initially planned for Sunday but was delayed due to bad weather at the launch site. The ALOS-4 is a successor to the current ALOS-2 and can observe a much wider area. Japan will operate both for the time being.
Japan's flagship H3 rocket reached orbit and released two small observation satellites in a key second test following a failed debut launch last year, buoying hope for the country in the global ...
