There was another comment about how the $100M is for the rocket and not the satellites, but I'm here to point out that Aerojet Rocketdyne is charging something like $100M to refurbish existing RS-25 engines from the Shuttle era for Artemis, per engine. In case it's not clear, that's not $100M to build the engine, it's already built and tested, it's $100M to "refurbish."

Furthermore it’s $100m to take a reusable engine and make it expendable.

You read that right, I didn’t make a typo.

The results may widely vary based on the context, but often writing something from scratch is easier than refactoring something existing.
