Reusable launcher insurance

Evolution of launch risk pricing as a reusable launcher accumulates a track record of successful flights on the same stages.

Definition

Reusable launcher insurance covers the launch risk specific to rockets whose first stage, or even the fairing, is recovered and reflown on later missions rather than destroyed on every flight. This model changes the nature of the statistical track record pricing relies on: the same physical stage accumulates flight cycles, and its reliability could in theory degrade with wear or instead improve with the maturity of refurbishment procedures, two opposing hypotheses that only a sufficiently long flight history can settle. Early in a reuse program, insurers lack data specific to the practice and tend to apply a caution premium, even for launchers whose expendable version was already well proven. As the number of successful flights on recycled stages accumulates, the risk premium tied to reuse tends to shrink and converge toward that of a conventional launch, or even fall below it if the demonstrated success rate exceeds that of the expendable fleet. The reusable launcher thus illustrates a case where pricing follows an explicit learning curve rather than a loss rate that is stable over time.

Example

SpaceX's Falcon 9 first stage passed several dozen successful flights on a single booster during the 2020s, a track record that helped make this launcher one of the cheapest to insure on the commercial market.
