Two hydrogen peroxide lift rockets with thrust that could be
varied from 100 to 500 pounds handled the LLRV’s rate
of descent and horizontal movement. Sixteen smaller
hydrogen peroxide rockets, mounted in pairs, gave the
pilot control in pitch, yaw and roll. As safety backups on
the LLRV, six 500-pound rockets could take over the lift
function and stabilize the craft for a moment if the main
jet engine failed.
