Registry · OPS-12
Orbital rockets and launch vehicles
Delta-V tracks 60 orbital launch vehicles, credited with 5,244 flights between them. The most-flown are Soyuz U (714 flights), Falcon 9 Block 5 (627 flights) and Kosmos-3M (11K65M) (445 flights). The heaviest lifter on the register is Space Shuttle, rated at 27,500 kg to low Earth orbit.
Each vehicle file carries the published spec sheet — height, diameter, payload to LEO and GTO, maiden flight, per-launch cost where an operator admits to one — alongside the flight record and whatever that vehicle is flying next.

Common questions
- How many orbital launch vehicles are there?
- Delta-V tracks 60 orbital launch vehicle configurations, of which 20 are in service and 5 are at least partly reusable. Together they account for 5,244 flights.
- Which rocket has flown the most times?
- Soyuz U has flown 714 times, more than any other vehicle configuration on the register.
- Which rocket lifts the most mass to low Earth orbit?
- Space Shuttle carries the highest published payload to low Earth orbit at 27,500 kg, built by National Aeronautics and Space Administration.
- What counts as a reusable rocket here?
- A vehicle is marked reusable when its operator recovers and reflies at least one stage — usually the booster. It does not mean the entire vehicle is recovered, and it says nothing about how many times a given stage has flown.
