These days there are more options available for reliable welding. Another reason for using fasteners rather than welding is that fasteners don't disrupt the heat treatment of metal. If you see something like 2024-T3, the "2024" part describes the composition of the alloy and the "T3" part describes the heat and chemical treatment that was done to the alloy. High temperature welding undoes the heat treatment. its hard to weld thin aluminum plates as I know, work for stuff like boat hulls who is thicker. Ships become much more sturdy then they replaced riveting with welding, as rivets tends to pop under less pressure than for an weld to crack at least with ship hull plates, had Titanic had an welded hull it would taken in water much slower because lots of the flooding was from seams there the rivets popped, yes the rivets was of softer steel than the hull so they could add them but it would anyway been an weak spot.

CatastrophicFailure Posted January 4, 2020 Share Posted January 4, 2020 (edited) For those who were wondering... Vertical integration it is! OooOOOoooh and new larger FH fairing confirmed!

The structure will probably look pretty similar to the old Titan IV Mobile Service Tower (MST) that used to be at SLC-40, though since SpaceX uses off-site payload encapsulation, they should be able to drop the cleanroom aspect. At least, presuming that late access to the payload isn't required. 2 hours ago, CatastrophicFailure said: OooOOOoooh and new larger FH fairing confirmed! Not quite. But they're working on it.

Apparently one story is 4.3m so the building would be 129m Quote Link to comment Share on other sites More sharing options...

I will guarantee you it will not be anywhere near tall enough for that. This is the service gantry the Titan IV used: Now imagine how large one neccessary for Starship would be.

What is the (theoretical) max size of a rocket that can be launched from land without destroying the launchpad? I hope Big Starship (18m version) doesn't exceed this limit.

Then only the very top of the nosecone will be sticking out from the ground. Like the Dnepr LV (aka converted ICBM Satan) which is launched from a silo and has special (cap? hood? portable mini-hangar?) hollow thing put on top for high payloads. Then the launch will look like the Sea Dragon's in the movie, and they can get to the cabin just by bus. (Also to be implemented with Kerbal Konstructs) Edited January 4, 2020 by kerbiloid Quote Link to comment Share on other sites More sharing options...

More like this Yes its some who has just made the image twice as wide. In practice the payload section will be larger, that is if this is just an tanker only who I see as plausible if they build one. If the payload mass of starship end up as too low say 80 ton it will make refueling little practical because all the launches needed and its likely they will fast track an 15-18 meter version tanker. The problem is launching the thing, as other say how heavy stuff can you launch from land? Launches from the sea has issues, primary is that you need to launch, recover, service and refuel the craft and also store them, this sounds a lot like the rolle of an aircraft carrier, however you are not launching 30 ton planes but an 5-12.000 ton rocket. Yes it can be build and it don't need to be an fast warship, it will probably be stationary like an oil platform. But will not be cheap nor fast to build and if stationary you need to hurricane proof it and the rockets in storage. Probably better to make an say 100x100 meter pool below the launch pad if you want to water to dampen the launch, this let you do other stuff like having fountains around the rocket on takeoff.
