The Reuse FlywheelWide moat

Reusability is not a one-time saving; it is a flywheel. Each additional flight of a proven booster spreads its build cost over more missions, generates fresh data that shortens the next refurbishment, and builds the operational muscle to turn a rocket around faster. Lower cost invites more customers and more of SpaceX's own Starlink launches; more launches mean more reuse and more data; and the loop tightens. This is why the gap to rivals has not held steady but widened — the leader is accelerating along a curve the followers have not yet stepped onto.

A flywheel of this kind is worth far more than any single technical trick, because it converts a lead into a self-reinforcing system. The competitor must match not a static target but a moving one, and must do so while absorbing the losses of the early, low-cadence years that SpaceX has already left behind. Flywheels are slow to start and very hard to stop, and this one has been spinning, faster each year, for the better part of a decade — up to 167 orbital launches in a single year¹.
