The Comet HLLV was a proposed super heavy-lift launch vehicle designed for NASA's First Lunar Outpost program, which was in the design phase from 1992 to 1993 under the Space Exploration Initiative. It was a Saturn V -derived launch vehicle with modernized engines, stretched fuel tanks, and strap-on boosters.

Based on the recommendations of the Stafford Synthesis report, First Lunar Outpost (FLO) would have relied on a massive Saturn-derived launch vehicle known as the Comet HLLV. The Comet would have been capable of injecting 230.8 t (508,800 lb) into low earth orbit and 88.5 t (195,200 lb) on a TLI making it one of the most capable vehicles ever ...

2024年5月27日 · The Comet HLLV was a bold concept that aimed to provide the United States with an unrivaled heavy-lift capability for lunar and Mars exploration. By leveraging proven technologies from the Saturn V and Space Shuttle programs, the Comet offered a potentially cost-effective path to super heavy-lift performance.

The Saturn V-derived heavy lift launch vehicle (HLLV) option was basically a stretched version of the old Apollo moon rocket, with two strap-on boosters for additional performance. F-1A and J-2S engines would have been used on all stages of the rocket.

In the early 1990s, as NASA was beginning to plan for missions beyond low Earth orbit following the end of the Apollo program, the need for a super heavy-lift launch vehicle became apparent. One of the most notable concepts that emerged during this period was the Comet Heavy Lift Launch Vehicle (HLLV).

A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads 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] .
