描述
The Long March 8A is an orbital launch vehicle developed by the China Academy of Launch Vehicle Technology based on the Long March 8. It has an increased capability of up to 7 tonnes to a 700 km altitude sun-synchronous orbit. It implements a larger 3.35 meters diameter liquid hydrogen/liquid oxygen 2nd stage, coupled with 2 upgraded version of the YF-75D engines used on the Long March 5 (known as the YF-75H) with increased thrust to 10 tonnes each through measures such as increased turbopump speeds.
The Long March 8A can also use a larger 5.2 meters diameter payload fairing.
