SpaceX has consistently demonstrated its honed logistics and engineering prowess over the course of 2020. Up till now, the company has constructed four starship prototypes, with the fourth iteration – known as the SN4 – currently undergoing extensive testing. Now, however, the company seems to be on the verge of another historic milestone.

Prior to the SN4, each previous Starship prototype could not graduate beyond the initial testing phase and was quickly destroyed. Consequently, SpaceX could only have a single prototype at any given time. This modus operandi now appears to be on the verge of a dramatic change. As per the pertinent reporting, SpaceX is now only a week away – at the longest – from completing its fifth Starship prototype, the SN5. This means that, for the first time ever, the company will have two functioning Starship prototypes concurrently.
