Falcon 9 vs Falcon Heavy
Falcon Heavy is essentially three Falcon 9 first stages bolted together, which triples liftoff thrust. Reusability improvements made the single-core rocket capable enough for almost every payload, which is why Falcon 9 has flown hundreds of times while Falcon Heavy remains a specialist.

Falcon Heavy
Falcon Heavy is SpaceX's three-core heavy-lift rocket, flown 12 times since its 2018 debut with launches including Psyche, Europa Clipper, and GOES-U.
Key differences
- Launch rate: Falcon 9 has flown 650+ missions and launches roughly every 2-3 days; Falcon Heavy had flown 12 times as of mid-2026.
- Payload: Falcon Heavy can lift about 63.8 t to low Earth orbit fully expendable versus about 22.8 t for Falcon 9, and it shines for heavy, high-energy missions like Europa Clipper.
- Recovery: Falcon Heavy's two side boosters land back at the Cape in tandem; the center core is usually expended on demanding trajectories.
- Price: a Falcon Heavy mission lists at roughly 50 percent more than Falcon 9, so customers only buy it when mass or orbit demands it.
