Current plans call for the Long March 9 to have a maximum payload capacity of 150,000 kg to low Earth orbit (LEO) and 54,000 kg to trans-lunar injection.[3][4] Its first flight is planned for 2033,[5] in anticipation of an increase in cadence by China's crewed lunar missions during the 2030s.[6][2] (As of 2023, the first crewed lunar landing attempt by China is expected to occur by the year 2030; this initial effort would use the under-development Long March 10 carrier rocket, the next-generation crewed spacecraft, and the Chinese crewed lunar lander.[7])
