Otherwise if it can go without the tiles, why these efforts about tiling. Perhaps the structural steel hull has some other functions than merely holding onto tiles?

Perhaps in other vessels aluminium was enough, and the steel was claimed as both structural and heat-proof? Quote Link to comment Share on other sites More sharing options...

To be fair, at the very least I think Elon said or tweeted that for LEO operations tiles might not be required. That's in my head, anyway, though I have no link ATM.

My best guess is that it's a test tank for structural validation and will be tested on that booster thrust simulator they've been building.

They could lower it with a crane to test catching as well, I suppose (vs hopping it). Quote Link to comment Share on other sites More sharing options...

IIRC, it was hoped to not need tiles if they went with a double-walled belly cooled by methane transpiration through pores in the outer skin, but eventually went with a more traditional approach (KISS). That said, steel needs no further protection on the lee sides, unlike aluminum which needs thermal blankets. So the steel approach is still simpler overall. Mmmm, glue….
