The H3's engine needs greater thrust than any other liquid rocket engines ever developed by Japan. To realize this highthrust, high-reliability and low-cost engine, we adopted the "expander bleed cycle" method, which JAXA has gained knowledge on from the development and operation of the LE-5 engine series.

Feb 14, 2023 · ③ Unlike the H-IIA/B rockets, H3 Launch Vehicle has no solid rocket booster and flies only with a liquid rocket engine (H3-30 configuration). In the case of conventional H-IIA/B rockets, the solid motor serves as a weight even after the liquid rocket engine properly started, and the rocket will not lift up until the solid motor is ignited.
