H3

H3 is Japan's new flagship rocket, built by Mitsubishi Heavy Industries to replace the H-IIA at much lower cost. Its first flight fails in March 2023, but from 2024 it launches Japanese Earth observation, navigation and defense satellites and, in 2025, the first HTV-X cargo ship to the International Space Station.
