While part fabrication and subassembly combination takes weeks or months on its own, those earlier steps can be done more or less all at once, meaning that SpaceX can prepare sections for several different ships and boosters at the exact same time. For the last 6 approximately months, at any given moment, SpaceX has actually had 40-60+ rings in work as part of 15-20+ various ring sections visible all throughout Starbase.
Within the recently, SpaceXs South Texas Starship factory appears to have kicked things into high gear and are now assembling the first orbital-class Super Heavy booster prototype at a breakneck rate.
While the assembly of the Super Heavy called Booster 4 (B4) wasnt too different to what CEO Elon Musk referred to as a “very tough” construct of Booster 3 approximately last week, deal with the rocket has noticeably accelerated. Considering that January 2020, the process of structure Starships and Super Heavy boosters has actually been fairly easy. Both offsite and onsite, basic materials (mostly sheet steel) are cut, bent, and welded into reasonably little parts that then make their method to (or around) Boca Chica by truck, forklift, or crane.
With the aid of jigs and good quantity of automation, the resulting hardware is then welded together to form domes, header tanks, transfer tubes, tank barrels, flaps, and more. As soon as subassembly is complete, those integrated rocket sections are reinforced with stringers, ribs, and baffles and outfitted with mechanisms, hardpoints, brackets, plumbing, and more. Lastly, final assembly– better known as stacking and by far the most visible step– can start and technicians stack each of those premade segments on top of each other to form a complete Starship or Super Heavy.
Respectively, each Starship and Super Heavy booster need 20 and 36 rings each, while each of the propellant storage tanks SpaceX is building itself for the rockets first orbital launch pad need 12-15. All informed, SpaceX normally has a mix of around 3-5 ships, boosters, and GSE tanks in some phase of assembly. Unsurprisingly, some assembly is more difficult than others and constructing the very first in a series of prototypes has practically usually taken far longer than the later average that establishes.

Booster 3 methane (CH4) tank assembly started a couple of days after the LOx tanks conclusion but continued even more quickly, concluding simply a couple of days later on. Two days after that, those 2 tank sections were then mated and welded together to complete Booster 3s complete ~ 65m (~ 210 ft) high airframe.
If SpaceX can sustain that rate for another few days, Booster 4 assembly will be the fastest of any full-height prototype ever built at Starbase, the majority of which have actually been Starship models that are half to about three quarters the size of Super Heavy.

In that sense, its not a substantial surprise that SpaceXs Booster 4 assembly has rapidly gone beyond the rate set with Booster 3 less than a month earlier. SpaceX began stacking Super Heavy B3 around May 20th, beginning with the rockets aft liquid oxygen (LOx) tank. 5 separate stacks are needed to turn the LOx tanks 23 steel rings into a single structure– a process that took SpaceX about a month with Booster 3.
< Now, simply 4 weeks after Booster 3 was rolled to the launch pad for proof and static fire screening, Super Heavy Booster 4 is well on its method to reaching its complete ~ 65m height almost two times as rapidly. With work beginning around July 16th, B4s oxygen tank is now simply missing an (exceptionally complex) engine section and the boosters methane tank was stacked to conclusion-- 13 rings high-- in less than 2 days. That leaves SpaceXs very first possibly flightworthy, orbital-class Super Heavy booster just two stacks away from completion less than 2 weeks after its assembly began.
