A heavy-lift launch vehicle, HLV or HLLV, is an orbital launch vehicle capable of lifting between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification)[1] into low Earth orbit (LEO).[2] As of 2019[update], operational heavy-lift launch vehicles include the Ariane 5, the Long March 5, the Proton-M and the Delta IV Heavy.[3] In addition, the Angara A5, the Falcon 9 Full Thrust, and the Falcon Heavy are designed to provide heavy-lift capabilities in at least some configurations but have not yet been proven to carry a 20-tonne payload into LEO. Several other heavy-lift rockets are in development. An HLV is between medium-lift launch vehicles and super heavy-lift launch vehicles.
