SpaceX is building the largest and most powerful rocket ever constructed. Starship Version 3, the next major upgrade to the company’s fully reusable launch system, is designed to stand approximately 408 feet tall and deliver more than 100 metric tons to low Earth orbit in a reusable configuration. If those numbers hold up in flight, V3 would surpass not only NASA’s Space Launch System but also the Saturn V that carried Apollo astronauts to the Moon, which lofted roughly 130 metric tons to LEO in its day.
As of mid-2026, no Starship V3 has flown. But the vehicle is more than a paper rocket. SpaceX has publicly tested Raptor 3 engines, the powerplant designed for V3, and the company’s iterative flight-test campaign with earlier Starship versions has accelerated rapidly over the past year. Understanding what is confirmed, what is projected, and what remains uncertain is essential for anyone tracking the future of spaceflight.
What the federal record confirms
The strongest public data on the Starship/Super Heavy system comes from the Federal Aviation Administration, which licenses every launch from SpaceX’s Boca Chica, Texas facility. The FAA describes the integrated vehicle as approximately 400 feet tall with a 30-foot diameter. The Super Heavy booster carries up to 37 Raptor engines; the Starship upper stage mounts up to 6. All test flights to date have operated under FAA oversight, including environmental compliance reviews and flight safety analyses.
Those baseline specs cover the general Starship/Super Heavy architecture without distinguishing between vehicle versions. The FAA filing uses “approximately 400 feet” and references Raptor engines without specifying a generation number. That means the regulatory record does not yet pin down the 408-foot height or the “Raptor 3” designation for V3 specifically.
On the comparison side, NASA provides a clear payload figure for the closest competing super-heavy vehicle. The agency states that SLS Block 1 can deliver more than 95 metric tons to low Earth orbit. SLS flew its first mission, Artemis I, on an uncrewed lunar trajectory in November 2022, and Block 1 remains the only configuration that has been built and flown. That 95-metric-ton number is the highest payload-to-orbit figure backed by a primary institutional source among currently active rockets.
What SpaceX has said about V3 and Raptor 3
SpaceX CEO Elon Musk and the company’s official communications have outlined Starship V3 as a significant step beyond the V1 and V2 variants that have been flying test missions. The key upgrades center on Raptor 3, a redesigned engine that SpaceX says is lighter, more powerful, and simpler to manufacture than its predecessors. Musk has stated publicly that Raptor 3 produces roughly 280 tons of thrust per engine, up from about 230 tons for earlier versions, while shedding significant mass through a reduction in part count.
The V3 upper stage is expected to be stretched to hold more propellant, which, combined with the higher-thrust engines, is how SpaceX projects the 100-plus-metric-ton reusable payload figure. In an expendable configuration, where the upper stage is not recovered, the theoretical capacity would be substantially higher, though SpaceX’s entire business model depends on reusability.
These are official company statements, not independent measurements. But they are not speculation either. SpaceX has shown Raptor 3 engines on test stands, and the company’s track record of iterating hardware rapidly lends weight to its projections. SpaceX also holds a NASA contract worth up to $2.89 billion to develop a Starship variant as the Human Landing System for the Artemis program, which requires the vehicle to meet performance milestones under NASA oversight. That contract represents institutional validation that goes beyond marketing.
How V3 compares to the biggest rockets ever built
The phrase “more than any rocket in history” sets a high bar, and the comparison extends beyond SLS. NASA’s Saturn V, which flew from 1967 to 1973, remains the most powerful rocket that has actually delivered payload to orbit. Saturn V could place approximately 130 metric tons into low Earth orbit and sent astronauts to the Moon on every Apollo landing mission. The Soviet Union’s Energia, which flew twice in the late 1980s, had a comparable class of lift capacity but never entered routine service.
SLS Block 1, at 95-plus metric tons, is the most capable rocket flying today but falls short of Saturn V’s record. Future SLS variants, Block 1B and Block 2, are designed to lift more, with Block 2 targeting around 130 metric tons, but neither has been built or flown.
If Starship V3 achieves 100-plus metric tons in a fully reusable mode, it would not quite match Saturn V’s expendable capacity on paper. But the comparison shifts dramatically when cost and reusability enter the picture. Saturn V was entirely expendable, with each launch consuming hardware worth billions in today’s dollars. A reusable Starship delivering 100 tons at a fraction of that cost per kilogram would represent a fundamentally different capability, one that could make large-scale orbital construction, deep-space cargo delivery, and massive satellite deployments economically viable for the first time.
What 100-plus tons to orbit would actually change
Raw payload numbers matter because they determine what missions are possible. At 100-plus metric tons per flight with rapid reuse, Starship V3 could reshape several sectors of spaceflight:
Lunar and Mars exploration: NASA’s Artemis program already depends on Starship as its lunar lander. A higher-capacity V3 could carry more supplies, habitat modules, or propellant per trip, reducing the number of launches needed to sustain a lunar base or stage missions to Mars.
Commercial space stations: Companies like Vast and Axiom Space are developing orbital habitats that need heavy modules lofted in single pieces. A 100-ton fairing payload eliminates the need to assemble stations from dozens of smaller launches.
National security missions: The U.S. Space Force has been watching Starship closely. A vehicle that can place very large payloads into diverse orbits on short notice would be attractive for both satellite deployment and rapid-response logistics.
Satellite mega-constellations: SpaceX’s own Starlink network is the most obvious near-term customer. Starship can already deploy Starlink satellites in batches far larger than Falcon 9 can manage; V3 would increase that throughput further.
What remains uncertain and what to watch for
Several critical questions are still open. No public FAA record lists a specific launch date or license application for a Starship V3 mission. SpaceX has historically revised its timelines, and the FAA licensing process for new vehicle configurations can introduce delays independent of hardware readiness.
Early V3 flights, whenever they occur, may not demonstrate full performance immediately. Test campaigns typically begin with conservative payloads, partial engine complements, or throttled thrust profiles. Validating the 100-ton reusable target will likely require multiple flights and iterative refinement, consistent with how SpaceX has developed every previous vehicle.
The transition from Raptor 2 to Raptor 3 across the full engine complement is another variable. Whether every engine on a V3 stack will be a Raptor 3 from the first flight, or whether SpaceX will mix engine generations during the production ramp, has not been confirmed in verifiable documentation.
Finally, payload capacity claims for any rocket depend on the target orbit, mission profile, and whether the upper stage is expended or recovered. The 100-ton figure appears to assume full reusability, but the precise assumptions behind it have not been published in a format that outside engineers can independently audit.
Where the evidence stands right now
The Starship/Super Heavy system, as described by the FAA, is approximately 400 feet tall, uses up to 37 Raptor engines on the booster and up to 6 on the upper stage, and is actively testing at Boca Chica. NASA’s SLS Block 1 has a documented capacity of more than 95 metric tons to low Earth orbit and has flown one uncrewed mission. Saturn V historically lifted about 130 metric tons.
SpaceX’s projection that Starship V3 will exceed all of these figures in a reusable configuration is grounded in real hardware development, a proven iterative testing approach, and a NASA contract that requires demonstrated performance. It is not yet an established fact. The gap between projection and proof will close only when V3 flies under a specific FAA license and delivers a measured payload to orbit.
That gap, however, has been narrowing faster than most observers expected. Each Starship test flight has retired risk and demonstrated capabilities that were theoretical just months earlier. For anyone following the space industry, the question is no longer whether SpaceX is serious about these numbers. It is how soon the hardware will catch up to the ambition.
