That much weight for the landing gear just seems way to high. Just my opinion.

John

He did say "less than a Model S", but that has to be the right ballpark for a comparison. The legs are quite large.

The legs are really long. That's why they weigh a lot. A squatter stage could use shorter and more efficient legs.

Good point.

That's what happens when you try to turn something that's not designed to carry out a task into something that can do it, rather than go with a clean sheet approach.

Good thing the "exchange rate" between stage dry mass and payload mass lost is so high for first stages, otherwise SX could have been in real trouble.

No comments yet about the ability/complexities to FSW Ti?

Titanium is also extremely amenable to diffusion Bonding as the protective oxide can be dissolved by the metal.
