H3
The H3 launch vehicle is Japan's flagship rocket jointly developed by JAXA and MHI. Overcoming the failure of Test Flight 1 in March 2023, it has performed consecutive successful launches since the launch of Test Flight 2 in February 2024.
With the H3 launch vehicle, we aim to provide launch services more closely aligned than ever before with customer needs, offering numerous launch opportunities.
