"Our Aerojet/FTT team has developed the key analytical
capability and technologies required for a next generation upper
stage rocket engine. We've demonstrated and validated the models
and technologies that will ensure an affordable program and much
shorter development schedule than previously possible... An
upper stage engine turbopump like this hasn't been successfully
developed in decades."
