Starship mass budget

[equiserre]

To satisfy my engineering curiosity, I started keeping track of every piece of information  that comes up on weight, just to check if weights are possible, making assumptions when lacking information. 120ton SS and 200ton SH do seem possible. Spreadsheet attached.

edit: all this should go in the Starship thread

Interesting piece of work.
The tanks are using 4mm SS, but it sounds like the plan is to move to 3mm thick stainless steel. Presume they will accomplish by further work hardening the SS,  or work hardening the welds by plannishing.
Remembering that the strength of the 304 SS is also enhanced at cryogenic temperatures.
