Falcon 9 vs Starship
Falcon 9 is the most-flown American rocket in history and the machine that funds SpaceX today. Starship is the vehicle meant to replace it entirely, trading a proven partially reusable design for full reusability at more than four times the payload.

Falcon 9 is SpaceX's partially reusable two-stage rocket and the most-flown American launch vehicle, with 670 Falcon family flights as of June 2026.

Starship
Starship is SpaceX's fully reusable super heavy-lift rocket and the largest ever flown, with twelve test flights since 2023 and a Version 3 debut in May 2026.
Key differences
- Status: Falcon 9 is operational with 650+ flights; Starship is mid-test-program with 12 flights and no customers flown yet.
- Reuse depth: Falcon 9 reuses its first stage and fairings (boosters have flown 35 times); Starship is designed to reuse everything, including the upper stage.
- Payload class: roughly 17.5 t to LEO with booster recovery for Falcon 9 versus a design target above 100 t for Starship.
- Transition: the heavier V3 Starlink satellites only fit on Starship, so SpaceX's own constellation is the anchor customer forcing the handover.
