The FG-47 (a.k.a. SpaB-54) is a Chinese solid rocket motor burning HTPB-based composite propellant.[1][4] It was developed by China Hexi Chemical and Machinery Corporation (also known as the 6th Academy of CASIC) for use in the Long March 2C SD/CTS/SMA third stage. It had its inaugural flight on the Iridium-MFS demonstration mission on September 1, 1997.[1][2][5][6]
