Styled as an upper stage for carrier rockets based on the w: Titan II, the LV-T91 "Cheetah" Liquid Fuel Engine is nonetheless a general purpose upper/orbital transfer stage.

Usage

As a size 1.5 / 1.875 m diameter part, the LV-T91 fits neatly between the LV-909 and Poodle. It similarly fits between them in terms of mass, specific impulse, and thrust to weight. This gives a narrow optimal usage window, although it remains a decent engine outside of it.

Product description

This engine will get you moving fast. Eventually.… Great for those long distance trips in space despite its namesake. Marketing, you know?
