Long March 9

01

Current status

Design centers on a reusable methalox first stage with 30 YF-215 engines. Large-diameter stainless-steel propellant tanks for the reusable stages have cleared manufacturing breakthroughs, with full-scale ground tests of major subsystems expected between 2026 and 2028. First flight is currently targeted around 2033.

    Mature the fully reusable Long March 9

    Develop the super-heavy, fully reusable Long March 9 for mega-constellation deployment and crewed deep-space missions later in the decade. Large-diameter stainless-steel propellant tanks for the reusable stages have cleared manufacturing breakthroughs, with full-scale ground tests of major subsystems expected between 2026 and 2028 and first flight still targeted around 2033.
