It has a total nominal mass of 729kg (1,607lb), of which 650kg (1,430lb) is propellant load and its burn out mass is 79kg (174lb). It has an average thrust of 44kN (9,900lbf) with a specific impulse of 289 seconds burning for 43 seconds, with a total impulse of 1.842MN (414,000lbf). While it was designed as an apogee kick motor and as such it flew in spin stabilized mode, it was also adapted to the Long March 1D third stage. It was paired with a RCS in a similar solution to the CTS.[2][4]
