The Long March 6A (Chinese: 长征六号甲运载火箭) or Chang Zheng 6A as in pinyin, abbreviated LM 6A for export or CZ 6A within China, is a Chinese medium-lift launch vehicle in the Long March family, which was developed by the China Aerospace Science and Technology Corporation (CASC) [6] and the Shanghai Academy of Spaceflight Technology (SAST).

There also exists a shorter boosterless variant of the 6A called the Long March 6C.

The vehicle was supposed to re-enter in one piece and then burn up.

[8][9] Following the November 2022 breakup, similar events were observed after the 26 March 2024, 4 July 2024, and 6 August 2024 launches.

The reason for the break ups are unclear, but may be related to upper stage passivation or insulation.
