The CECE is based on the existing Pratt & Whitney Rocketdyne RL10
upper stage rocket engine. Previous first-hand flight experience, as
well as this data, will allow engineers to develop simulation models
that can focus testing for efficiency and effectiveness.

Proving once again that the RL10 is the workhorse of US vacuum rocket
engines. :-)
