450N(100lbf) and 22N(5lbf) hydrazine/MON3 thrusters were developed in 2001. Since then, their excellent performance and reliability have been well recognized by US satellite manufacturers. Over 100 hydrazine/MON3 thrusters have been flown and been successfully operated.
IHI Aerospace has also developed 120N(27lbf) and 490N(110lbf) MMH/MON3 thrusters for the International Space Station cargo spacecraft, HTV(H-Ⅱ Transfer Vehicle), as well as its propulsion subsystem. They were flown with HTV3 in 2012 and the mission was completed successfully.
