- SLS booster 3-segments.

The OA Advanced Boosters for SLS are four segment.

The stick.

Is.

Back.
It is not. In fact, this is what you get when you are a world class integrator that actually does the trades to determine the configuration that makes economic sense.
Not the pork sucking Griffin acolytes of before. From Ed's interpretation it would seem like a two segment first stage, a one segment second stage and an H2 third. Probably 120tonne per segment. Quite similar to Ariane 6 PPH concept.
The Ariane 6 PPH was to use Ariane 5 US ( 28t + 36kbls engine). It is the more capable an most likely cheaper BE3 US that will make difference.
