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 launch vehicle of the Long March family, which was developed by the China Aerospace Science and Technology Corporation (CASC) [4] and the Shanghai Academy of Spaceflight Technology (SAST).
The vehicle is a further development of the Long March 6, with 2 YF-100 engines on the first stage as opposed to 1 on the Long March 6, augmented by 4 solid rocket boosters. The Long March 6A is China's first rocket with solid rocket boosters. There also exists a shorter boosterless variant of the 6A called the Long March 6C.
The maiden launch of the Long March 6A took place on March 29, 2022, successfully reaching orbit.[5] It was also the first launch from the newly built launch complex 9A in Taiyuan.
