Why does Starship only have 2 rear fins?!

We’re less than a week away from this year’s Starship update from Elon Musk. And before the party gets started, we’re already catching some major changes happening before our eyes.

The most obvious change is the fact that Starship only has two finny / flappy / airbrakey things instead of three. Now the previous version touted just last year at the DearMoon event showed Starship sporting 3 fins that were also its landing legs.

So now that we’re seeing only two, the question has come up, why? Why two?

So today we’re going to do a really quick rundown on why two might be better than three, show you some potential problems with three fins, and then we’ll show you exactly how they’ll control their reentry and landing with just 2 rear fins.
