Prior to being named Half Cat, this engine was known as RY-101, a design number designation that still occasionally appears as a way to differentiate similar engines. It has conducted seven static fires and three flights and is now retired. Propellant flow is controlled by two independent and identical pyrotechnic valves. It contains a solid propellant igniter which is lit just before initiation of the valves. The oxidizer tank is passively vented through a 0.8mm orifice plug. The combustion chamber is protected by an ablative thermal liner made of CHAMBERSAFE.
