NF-104A Reaction Control System (RCS) Lockheed pilot Jack Woodman points out the wing RCS The Reaction Control System (RCS) consisted of eight pitch/yaw thrusters (four for each axis) - shown in the left photo and four roll thrusters - shown in the right photo. They used the same kind of hydrogen peroxide fuel as the main rocket engine from a dedicated 155 lb (70 kg) fuel tank and were controlled by the pilot using a handle mounted in the instrument panel. The pitch/yaw thrusters were rated at 113 lbf (500 N) thrust each and the roll thrusters were rated at 43 lbf (190 N) thrust. copyright © Lockheed via Pete Cluckey
