According to the article, they're probably going to skip over SN12, 13, and 14 in order to try with a later design. That makes sense, since it's likely that several crashes happen between when construction starts on a new rocket and it finishes. Once it's done, they may have design might already be out of date. > Fortunately, as part of its iterative development program, SpaceX is building a Starship vehicle at a rate of every two to three weeks. So the next prototype—likely to be SN15 as the company skips ahead toward a more advanced version—may be ready to fly in several weeks. Still, SpaceX would have liked to have gotten this one back in one piece.
