Super heavy-lift launch vehicle
A super heavy-lift launch vehicle (SHLLV) is a launch vehicle capable of lifting more than 50 t (110,000 lb) of payload into low Earth orbit (LEO).[1][2]
Flown vehicles
Retired
- Saturn V, with an Apollo program payload of a Command Module, Service Module, and Lunar Module. The three had a total mass of 45 tonnes (99,000 lb).[3][4] When the third stage and Earth-orbit departure fuel was included, Saturn V actually placed 140 t (310,000 lb) into low Earth orbit.[5] The final launch of Saturn V placed a 77,111 kg (170,001 lb) payload into LEO.
- The Space Shuttle orbited a combined[lower-alpha 1] 122,534 kg (270,142 lb) when launching the Chandra X-ray Observatory on STS-93.[6] Chandra and its two-stage Inertial Upper Stage booster rocket weighed 22,753 kg (50,162 lb).[7]
- Energia launched two payloads, only one of which reached orbit, before the program was cancelled: the Polyus weapons platform at approximately 80 t (180,000 lb) and Buran orbiter. The system was designed to launch up to 105 t (231,000 lb) to low Earth orbit.[8][9] Polyus failed to enter orbit due to a software error on the kick-stage.
The Space Shuttle and Buran differed from traditional rockets in that both launched what was essentially a reusable, manned stage that carried cargo internally.
Unproven
- Falcon Heavy is rated to launch 63.8 t (141,000 lb) to low Earth orbit (LEO) in a fully expendable configuration. In a partially reusable configuration in which its two boosters are recovered, it can launch an estimated 57 t (126,000 lb) to LEO.[10][11][lower-alpha 2] Its first launch occurred on 6 February 2018, but it has not yet launched a heavy or super-heavy payload.

^A Includes mass of Apollo Command/Service Modules, Apollo Lunar Module, Spacecraft/LM Adapter, Saturn V Instrument Unit, S-IVB stage, and propellant for translunar injection; payload mass to LEO is about 122.4 t (270,000 lb)[22]
^B Includes mass of orbiter and payload during STS-93; deployable payload is 27.5 t (61,000 lb)
^C Required upper stage or payload to perform final orbital insertion
^D No stages recovered, fairing recovery possible
^E Booster cores recovered, center core expended, fairing recovery possible
^F As of 2018, it has not yet flown in this configuration; only flown in its most reusable configuration with all three cores making landing attempts.
^G Though payload capacity has not been officially announced, the 45 t (99,000 lb) payload for the two-stage variant[18] and thrust levels for the first stage suggest placement of the vehicle in the super-heavy lift class.[23]
^H Does not include dry mass of spaceship
Proposed designs
The Space Launch System (SLS) is a super heavy-lift launch vehicle currently under development in the U.S. by NASA.[24] The Block 1 configuration is currently targeted for launch in June 2020,[13] with other configurations of increasingly higher lift capacities from 2023 to 2029.[17] Block 1 will be capable of launching a minimum of 70 t (150,000 lb) to low-Earth orbit, and approximately 26 t (57,000 lb) to a trans-lunar injection point.[25][26]
The 140 t (310,000 lb) to LEO capable Long March 9 has been proposed by China.[27] It has a targeted capacity of 50 t (110,000 lb) to lunar transfer orbit and first flight by 2030.[28]
In August 2016, Russia's RSC Energia announced plans to develop a super heavy-lift launch vehicle using existing components instead of pushing the less-powerful Angara A5V project.[29][30] This would allow Russia to launch missions towards establishing a permanent Moon base with simpler logistics, launching just one or two 80-to-160-tonne super-heavy rockets instead of four 40-tonne Angara A5Vs implying quick-sequence launches and multiple in-orbit rendezvous.[29] In February 2018, the КРК СТК (space rocket complex of the super-heavy class) design was updated to lift at least 90 tonnes to LEO and 20 tonnes to lunar polar orbit, and to be launched from Vostochny Cosmodrome.[31]
Cancelled designs
Numerous super-heavy lift vehicles have been proposed and received various levels of development prior to their cancellation.
As part of the Soviet Lunar Project four N1 rockets with a payload capacity of 95 t (209,000 lb), were launched but all failed shortly after lift-off (1969-1972).[32] The program was suspended in May 1974 and formally cancelled in March 1976.[33][34]
The U.S. Ares V for the Constellation program was intended to reuse many elements of the Space Shuttle program, both on the ground and flight hardware, to save costs. The Ares V was designed to carry 188 t (414,000 lb) and was cancelled in 2010, though much of the work has been carried forward into the SLS program.
A 1962 design proposal, Sea Dragon, called for an enormous 150 m (490 ft) tall, sea-launched rocket capable of lifting 550 t (1,210,000 lb) to low Earth orbit. While the design was validated by TRW, the project never moved forward due to the closing of NASA's Future Projects Branch.[35][36]
SpaceX's first publicly released design of its Mars transportation infrastructure was the ITS launch vehicle unveiled in 2016. The payload capability was to be 550 t (1,210,000 lb) in an expendable configuration (equal to the Sea Dragon) or 300 t (660,000 lb) in a reusable configuration.[37] In 2017, it was succeeded by BFR.

Notes
- ↑ The Space Shuttle orbiter itself contributed to reaching low Earth orbit therefore the validity of its inclusion as payload mass is debatable.
- ↑ A partially reusable configuration where three cores are recovered is classified as a heavy-lift launch vehicle since payload to LEO is under 50,000 kg.

Energia and Roscosmos are “working on a super heavy-lift launch vehicle (SHLLV) that would use an engine that we already have, the RD-171,” Vladimir Solntsev told Izvestia newspaper. [...] The proposed new SHLLV would initially have a LEO lift of 80 tonnes with a potential to increase the figure to 120 tonnes or even 160 tonnes, according to Solntsev.
