What is launch cadence?
Launch cadence refers to the frequency at which a launch vehicle provider executes launches, typically measured as launches per year. High cadence is fundamental to the economics of reusable rockets (amortising fixed overhead across many flights), to the rapid deployment of mega-constellations (which need hundreds of launches to reach full operational capability), and to the responsiveness of launch markets where customers need timely access to orbit.
The SpaceX cadence benchmark
SpaceX set the global record with 96 launches in 2023 across its Falcon 9 and Falcon Heavy fleet — approximately one launch every 3.8 days. In 2024, this increased further. This cadence was enabled by: fleet of approximately 20 active boosters, each reflown multiple times; two active launch sites (Cape Canaveral SLC-40 and LC-39A; Vandenberg SLC-4E); rapid turnaround operations with a target of 24 hours between some flights; and dedicated Starlink launches that provide a predictable, internally managed manifest to fill gaps between commercial customer slots.
Industry-wide implications
High cadence drives down per-launch fixed costs, as engineering, operations, and infrastructure teams are spread across more revenue-generating events. It also improves reliability through practice and learning — SpaceX's Falcon 9 achieved 300+ consecutive successful launches before its first in-flight anomaly. For constellation operators, cadence determines deployment schedule: Starlink needed approximately 350 Falcon 9 launches to deploy its initial 10,000-satellite constellation. For smaller operators, dedicated access to high-cadence vehicles creates more predictable launch scheduling than waiting for infrequent large rockets.
