[6] There are also plans for a variant, the Long March 10A,[7] which is designed primarily for future low Earth orbit crew and cargo transport to the Chinese Space Station.

Its notional debut was at the 12th China International Aviation & Aerospace Exhibition in November 2018, where it was announced that the China Academy of Launch Vehicle Technology (CALT) is developing a vehicle with a lunar orbit capacity of up to 30 tons, meeting the requirements for crewed lunar exploration.

[9] Documents and presentations in subsequent years depicted modified Long March 5 configurations known as CZ-5DY (pinyin abbreviation for 'Deng Yue' 登月 or lunar landing), CZ-5G, and CZ-5H.

An article later published by China Aerospace Science and Technology Corporation also used the term "Long March 10" to refer to the rocket.

[3][9] The standard variant of the vehicle consists of two boosters, first, second and third stage cores, escape tower, and fairing.

[11] The Long March 10A is a single stick variant with only 2 stages; it has 7 YF-100K engines on the first stage and a single YF-100M engine on the second stage, This variant is designed for low Earth orbit crew and cargo flights; it is part of the Chinese space program's plan to increase lift capacity, explore reusability, and phase out hypergolic fuels for its carrier fleet.
