>HELSINKI, Finland — A senior designer with the China Academy of Launch Vehicle Technology has presented updated details for an upcoming series of new rockets to expand China’s launch capabilities, including super-heavy-lift and reusable rockets.
>Long Lehao, a chief designer with CALT, a major launch vehicle institute under the main contractor for China’s space activities, revealed the details in a lecture at Tsinghua University in Beijing on May 31.
>Long gave an overview of the history and progress of Chinese launch vehicles before providing updates on new projects under development, notably the Long March 9.
>The Long March 9 will be a Saturn 5-class super-heavy-lift rocket comparable in capacity to the Space Launch System currently being developed under NASA.
>According to Long, the Long March 9 will be capable of lifting 140 metric tons to low Earth orbit, 50 tons to Earth-Moon transfer orbit, and 44 tons to Earth-Mars transfer orbit.
>The 93-meter-high Long March 9 is expected to have a launch mass of over 4,000 metric tons, producing close to 6,000 tons of thrust.

There’s not much to talk about, but the YF-220 as it’s name suggests will be a engine producing 200 tons or 2200kN of thrust. We know it’ll power the second-stage of the Long-March 9 mega-rocket and will use hydrolox for propellant.
