Super Heavy-lift Launch Vehicle

A super heavy-lift launch vehicle (SHLLV) is a launch vehicle capable of lifting more than 50,000 kg (110,000 lb) of payload into low Earth orbit (LEO).[1][2]

Flown vehicles


  • Saturn V, with an Apollo program payload of a Command Module, Service Module, and Lunar Module. The three had a total mass of 45,000 kg (99,000 lb).[3][4] When the third stage and Earth-orbit departure fuel was included, Saturn V actually placed 140,000 kg (310,000 lb) into low Earth orbit.[5] The final launch of Saturn V placed a 77,111 kg payload into LEO.
  • The Space Shuttle orbited a combined[a] 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 80,000 kg (180,000 lb) and Buran. The system was designed to launch up to 105,000 kg (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 orbiter differed from traditional rockets in that both launched what was essentially a reusable, manned stage that carried cargo internally.


  • Falcon Heavy is rated to launch 63,800 kg (140,700 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 57,000 kg (126,000 lb) to LEO.[10][11][b] Its first launch occurred on 6 February 2018, but it has not yet launched a heavy or super-heavy payload.

^A Includes mass of orbiter and payload during STS-93; deployable payload is 27.5 t (61,000 lb)
^B No stages recovered, fairing recovery possible
^C Booster cores recovered, center core expended, fairing recovery possible
^D As of 2018, it has not yet flown in this configuration; only flown in fully reusable configuration with all three cores making landing attempts
^E Though payload capacity has not been officially announced, the 45,000 kg (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.[21]
^F Does not include dry mass of spaceship; including it would make the payload 235 t (518,000 lb)

Proposed designs

The Space Launch System (SLS) is a super heavy-lift launch vehicle currently under development in the U.S. by NASA.[22] 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]

The 140,000 kg (310,000 lb) to LEO capable Long March 9 has been proposed by China.[23] It has a targeted capacity of 50 tonnes to lunar transfer orbit and first flight by 2030.[24]

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.[25][26] 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.[25] In February 2018, the (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.[27]

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 95,000 kg (209,000 lb), were launched but all failed shortly after lift-off (1969-1972).[28] The program was suspended in May 1974 and formally cancelled in March 1976.[29][30]

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 188,000 kg (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 550,000 kg (1,200,000 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.[31][32]

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 550,000 kg (1,200,000 lb) in an expendable configuration (equal to the Sea Dragon) or 300,000 kg (660,000 lb) in a reusable configuration.[33] In 2017, it was succeeded by BFR.
