Ariane 6 vs Falcon 9: Payload, Price and Availability Compared

Falcon 9 and Ariane 6 overlap in the medium to heavy class but serve buyers differently. On the published figures, Falcon 9 lifts 22,800 kg to low Earth orbit (LEO) and 8,300 kg to geostationary transfer orbit (GTO), while Ariane 64 lifts about 21.6 tonnes to LEO and about 11.5 tonnes to GTO, and Ariane 62 about 10.3 and 4.5 tonnes. Neither SpaceX nor Arianespace lists a dedicated launch price on its vehicle pages, so the price comes from a quote. This comparison covers payload, fairing, launch sites, reuse, availability and how to approach pricing.

Payload capacity

Falcon 9: 22,800 kg to LEO, 8,300 kg to GTO and 4,020 kg to Mars, according to SpaceX.
Ariane 62 (two boosters): approximately 10.3 tonnes to LEO and approximately 4.5 tonnes to GTO, according to ESA.
Ariane 64 (four boosters): approximately 21.6 tonnes to LEO and approximately 11.5 tonnes to GTO, according to ESA.

For LEO missions, Falcon 9 and Ariane 64 publish similar figures. For GTO, Ariane 64 publishes the higher figure, while Ariane 62 sits well below Falcon 9 in both orbits. The two companies do not define their reference orbits in the same way on these pages, so the figures are a first filter. Our overview of launch vehicles by payload capacity puts both rockets next to other launchers.

Fairing and upper stage

Falcon 9 fairing: 13.1 m high and 5.2 m in diameter, made of carbon composite, according to SpaceX. SpaceX says it continues to recover fairings for reuse.
Ariane 6 fairing: two lengths, 20 m and 14 m, both 5.4 m in diameter and made of carbon fibre polymer composite, according to ESA.
Ariane 6 upper stage: powered by the Vinci engine on liquid oxygen and hydrogen, which ESA says allows the stage to reach a range of orbits on a single mission and typically burn multiple times.

The longer Ariane 6 fairing gives room for tall spacecraft or stacked payloads. The restartable Vinci stage is relevant for missions that drop payloads into different orbits on one flight.

Launch sites

Falcon 9: SpaceX operates Space Launch Complex 40 at Cape Canaveral Space Force Station and Launch Complex 39A at Kennedy Space Center in Florida, and Space Launch Complex 4 East at Vandenberg Space Force Base in California, according to its Rideshare Payload User's Guide.
Ariane 6: launches from Europe's Spaceport in French Guiana. ESA notes that the spaceport is just 5 degrees north of the equator, which helps flights to the east.

The site matters for export rules, shipping and orbit. A launch from near the equator suits geostationary missions, while Vandenberg serves polar and sun-synchronous orbits. Read our guide on shipping a satellite to the launch site for the logistics.

Reuse

SpaceX describes Falcon 9 as the world's first orbital class reusable rocket and says reuse lets it refly the most expensive parts of the rocket, which drives down the cost of access to space. ESA describes Ariane 6 as three stages made of two or four boosters, a main stage and an upper stage, and its overview does not describe any reuse of these stages.

Availability and order book

Falcon 9 flies dedicated missions and regular rideshare flights. SpaceX publishes its open rideshare flights, and our rideshare launch schedule lists them.

Ariane 6 has a growing order book. In September 2026 Arianespace announced seven agreements and memorandums of understanding covering almost ten launches, its largest order intake since Ariane 6 entered service. According to Arianespace:

Amazon Leo: ordered six more Ariane 64 launches, raising the total planned under its agreement from 18 to 24 by 2031. Three Ariane 6 missions in 2026 placed 100 Amazon Leo satellites in orbit in less than five months.
Eutelsat: ordered two Ariane 64 launches for its OneWeb constellation, scheduled for 2027 and 2028.
KT SAT: a geostationary satellite built by AscendArc will launch on Ariane 6 in 2028.
The Exploration Company: its Nyx capsule will fly on Ariane 64 for a demonstration mission under ESA's ALADDIN initiative.

A full order book is good news for the launcher but can mean longer waits for new customers. Ask both providers for the earliest realistic date for your orbit; our article on launch lead times explains the planning.

Rideshare options

Both rockets also carry smaller satellites. ESA says Ariane 6 payload carriers let small satellites lighter than 200 kg ride piggyback on the launch of a main payload. SpaceX runs dedicated rideshare missions on Falcon 9, which our SpaceX rideshare guide describes.

Price

When we checked on 11 October 2026, neither the SpaceX Falcon 9 page nor Arianespace's Ariane 6 pages listed a price for a dedicated launch. Prices depend on the orbit, configuration, mission services and contract terms. Our article on Falcon 9 launch costs covers what is publicly known about SpaceX pricing. For a binding figure you need a quote for your mission. Our tip: send both providers the same mass, target orbit, launch window and list of required services, so that the offers can be compared line by line.

Which one fits your mission?

Single satellite to LEO or SSO: both are candidates; compare the next available date and the rideshare options.
Heavy satellite to GTO: Ariane 64 publishes the higher GTO figure; Falcon 9 publishes 8,300 kg.
European institutional or sovereignty requirements: Ariane 6 launches from Europe's Spaceport and is operated by Arianespace.
Tall or stacked payloads: the 20 m Ariane 6 fairing is the longer option.

On Carrier Space you can compare both rockets in the direct comparison and send a request to several providers at once through the request portal.

Frequently asked questions

Is Ariane 6 more powerful than Falcon 9?

It depends on the version and orbit. Ariane 64 publishes about 11.5 tonnes to GTO against 8,300 kg for Falcon 9, and a similar LEO figure of about 21.6 tonnes against 22,800 kg. Ariane 62 is smaller than Falcon 9 in both orbits.

How much does an Ariane 6 launch cost?

Arianespace does not publish a price on its Ariane 6 pages. You get a price by requesting a quote for your mission.

Is Ariane 6 reusable?

ESA's Ariane 6 overview does not describe any reuse of the rocket's stages. Falcon 9 is reusable, according to SpaceX.

Where do Ariane 6 and Falcon 9 launch from?

Ariane 6 launches from Europe's Spaceport in French Guiana. Falcon 9 launches from Cape Canaveral and Kennedy Space Center in Florida and from Vandenberg in California.

Can small satellites fly on Ariane 6?

Yes. ESA says payload carriers let small satellites lighter than 200 kg ride piggyback on the launch of a main payload.
