It was developed by China Hexi Chemical and Machinery Corporation (also known as the 6th Academy of CASIC) for use in the Dong Fang Hong 2 satellite bus for insertion into GSO orbit.[5] It has a total nominal mass of {{convert|580|kg|lb|abbr=on}}, of which {{convert|505|kg|lb|abbr=on}} is propellant load and its burn out mass is {{convert|75|kg|lb|abbr=on}}. It has an average thrust of {{convert|40.9|kN|lbf|abbr=on}} with a specific impulse of 289 seconds burning for 35 seconds, with a total impulse of {{convert|1.432|MN|abbr=on}}. This motor introduced a series of innovations for the Chinese solid motor industry: first use of glass fibre wound cases, carbon/carbon nozzle throat insert material, contoured divergent nozzle, and non-destructive test of the motor grain. The initial version had the manufacturing code FG-15 was associated to the DFH-2 bus and flew twice. The FG-15B was used by the DFH-2A bus and flew five times.
