Initially designed and built as a part of the NASA Bantam System Technology program, aiming for a low cost, high power propulsion system, it was later modified by Lockheed Martin for use as a launch abort engine. A derivative of the RS-88 is used by the Boeing CST-100 "Starliner" spacecraft for launch aborts under the name "Launch Abort Engine - LAE".
