Performance and use

Draco thrusters generate 90 pounds-force (400 newtons) of force using a mixture of monomethyl hydrazine fuel and nitrogen tetroxide oxidizer.

Eighteen Draco thrusters will be used on the Dragon spacecraft for attitude control and maneuvering.[1] dual-redun­dant in all axes: any two can fail and still have complete vehicle control in pitch, yaw, roll and translation.

Four Draco thrusters will be used on the Falcon 9 second-stage as a reaction control system.[3]
