A rocket catapult assembly for an ejection seat may comprise a motor assembly including a proximal end and a distal end, an outlet tube coupled to the distal end, and a valve coupled to the outlet tube. The valve may be configured to vary an operating pressure based on an occupant's weight. The valve may be in a closed configuration, on open configuration, or a partially open configuration during ejection of the ejection seat.
