Falcon 9 vs Falcon Heavy
Falcon Heavy is built from three Falcon 9 first stages joined together, which roughly triples liftoff thrust. Successive Falcon 9 upgrades made the single-core rocket capable enough for almost every payload, so Falcon 9 flies constantly while Falcon Heavy stays a specialist that launches once or twice a year.

Falcon 9
Falcon 9 is SpaceX's two-stage rocket, with a reusable first stage, 702 liftoffs through November 12, 2026, and crew, science, and Starlink roles.

Falcon Heavy
Falcon Heavy is SpaceX's three-core heavy-lift rocket, flown 14 times since its 2018 debut with launches including Psyche, Europa Clipper, and Roman.
Key differences
- Launch rate: Falcon 9 had made 702 physical liftoffs through November 12, 2026, including 120 in 2026. Falcon Heavy has flown 14 times since 2018, most recently NASA's Roman Space Telescope on August 30, 2026 and the National Reconnaissance Office's NROL-97 on October 1.
- Payload: SpaceX publishes 63,800 kg to low Earth orbit for a fully expendable Falcon Heavy, against 22,000 to 22,800 kg for a fully expendable Falcon 9. SpaceX does not publish one current Falcon 9 limit for recovery missions because the available performance depends on the trajectory. The Heavy margin matters for high-energy missions such as Europa Clipper.
- Recovery: Falcon Heavy's two side boosters land in tandem and have succeeded on all 24 attempts. The center core is harder: it has been recovered once, in 2019, and never reached port, so SpaceX now expends it.
- Price: SpaceX's current price sheet quotes only Falcon 9, at 74 million dollars through 2026. The last published Falcon Heavy list price, 97 million dollars set in a 2022 inflation adjustment, was about 45 percent above the 67 million Falcon 9 then cost. Government awards that bundle mission services run much higher, such as about 178 million dollars for Europa Clipper.
