H3 Launch Vehicle

The H3 rocket is a Japanese medium-lift launch vehicle developed by JAXA and Mitsubishi Heavy Industries (MHI). It is the successor to the H-IIA and H-IIB rockets, designed to reduce launch costs through the use of the lower-cost LE-9 main engine. The H3 features a modular design with two or three first-stage engines and zero, two, or four solid rocket boosters, allowing it to accommodate a variety of payload sizes. Development began in 2013, and the first flight took place in March 2023; the launch ended in failure when the second-stage engine did not ignite. The first successful test flight occurred in February 2024.
