I look into construction and Launch cost of large Rocket.
part of this study https://www.secretprojects.co.uk/threads/next-lunar-colonisation-program.42456/
SpaceX made impressive work
To compare Starship/Superheavy with Saturn V.
one Saturn V cost in today price $1.15 billion, were Construction cost of $683 million.
i can only made estimation on Starship/Superheavy Construction cost,
but its mostly build from 304L Steel who cost $1,5/kg compare to $2.6/kg of Alu 2014 T6 used on Saturn V.
This Imply the Starship/Superheavy tanks Construction cost only 57% of that of Saturn V tanks.
The Saturn V use 5xF-1 6xJ-2 Engines, the Starship/Superheavy 39x Raptor engines.
The use of one engine for first and second stage is cost reduction compare to Saturn V different Engines.
Next to that SpaceX trow everything out, they not need in Starship/Superheavy.
No third stage, no disposable interstage or Auxiliary Propulsion system or retro rockets.
On Propellants Saturn V use Lox, PR-1 and Liquid Hydrogen, total cost is $1708856 in today prise.
Starship/Superheavy use only Lox and Liquid Methane, total cost is $1586080.
Since i don't have certain information on Starship/Superheavy Construction cost and Raptor price
i estimate that Starship/Superheavy build cost lies far under $380 million.
biggest issue is launch cost and refurbish cost for the Launch Pad.
if that labour intensive with allot personal, this will be very expensive.
if SpaceX manage to automate the launches and refurbish the pad, it will save allot money.
