SpaceX, which flew 165 Falcon launches in 2025 on reusable boosters, against Arianespace, which operates Europe's expendable Ariane 6. Arianespace retired Ariane 5 in July 2023 and flew Ariane 6 for the first time in July 2024.

| Career launches (through 9 Oct 2026) | Falcon 9 Block 5: 636; Falcon Heavy: 14 | Ariane 5: 117 (1996 to July 2023); Ariane 6: 9 (first flight July 2024) |
| Launches in 2024 | 134 Falcon launches | 3 (Ariane 6 first flight, last Vega, Vega C) |
| Launches in 2025 | 165 Falcon launches | 4 Ariane 6 launches |
| Government missions | In 2025: 11 of 12 U.S. National Security Space Launch medium and heavy missions, and all 5 U.S. crew and cargo flights to the ISS | Ariane 6 flights in 2025 carried CSO 3, Metop-SG A1, Sentinel-1D and two Galileo satellites |
| Constellation role | Launches its own Starlink: about 9,600 satellites in orbit (Mar 2026) | Amazon booked 18 Ariane 6 launches (2022); the first Ariane 64 carried 32 Amazon Leo satellites (Feb 2026) |
| Near the equator | No: sites in Florida and California | Yes: Kourou lies at 5°3′ N, which ESA says makes it ideally placed for GTO launches |
Reuse is the structural difference. By 31 March 2026 Falcon first stages had landed more than 570 times, according to SpaceX's IPO prospectus, and SpaceX flew 165 Falcon launches in 2025, 122 of them carrying its own Starlink satellites. Arianespace flew Ariane 5 117 times between 1996 and its final launch in July 2023, then moved to Ariane 6, which first flew on 9 July 2024.
Ariane 6 flies as Ariane 62, with two solid boosters (up to 4,500 kg to GTO and 10,300 kg to LEO), or Ariane 64, with four (up to 11,500 kg to GTO and 21,600 kg to LEO), according to CNES. Its upper stage uses the reignitable Vinci engine. Ariane 6 is expendable, and Arianespace publishes no list price for it. ESA's Themis demonstrator, built to test rocket recovery and reuse with the methane-fuelled Prometheus engine, was still in ground rehearsals in October 2026, with its first flights planned from Esrange in Sweden.
SpaceX describes itself as the primary launch provider for the U.S. government: in 2025 it launched 11 of the 12 National Security Space Launch medium and heavy missions and all five U.S. crew and cargo missions to the International Space Station. ESA says Ariane 6 was developed in response to the needs of European independence in accessing and using space, and its four 2025 flights carried CSO 3, Metop-SG A1, Sentinel-1D and two Galileo satellites. European programmes have not flown on Ariane alone, though: Galileo satellites launched on Falcon 9 from Florida twice in 2024.
Kourou lies at 5°3′ north, just over 500 km from the equator, which ESA says makes it ideally placed for launches into geostationary transfer orbit. SpaceX's Falcon sites are in Florida and California.
SpaceX said in its June 2026 prospectus that it expects Starship to begin delivering payloads to orbit in the second half of 2026. Arianespace's chief executive, David Cavaillolès, has said the aim is to raise Ariane 6 cadence toward 9 to 10 launches a year as soon as possible; Ariane 6 flew 4 times in 2025. Amazon booked 18 Ariane 6 launches in 2022, alongside 38 on ULA's Vulcan Centaur and 12 on Blue Origin's New Glenn, and the first Ariane 64 carried 32 Amazon Leo satellites in February 2026.

There is no like-for-like answer, because Arianespace publishes no list price for Ariane 6. SpaceX lists a 2026 Falcon 9 launch at $74 million, for up to 22,800 kg to low Earth orbit; Ariane 62 lifts up to 10,300 kg and Ariane 64 up to 21,600 kg. Ariane 6 is expendable, while Falcon 9 reuses its first stage.
ESA says Ariane 6 responds to the needs of European independence in accessing and using space. Its four 2025 flights carried CSO 3, Metop-SG A1, Sentinel-1D and two Galileo satellites. European programmes have also bought Falcon 9: Galileo satellites launched from Florida twice in 2024.
Not yet. Ariane 6 is fully expendable. ESA’s Themis reusable-stage demonstrator was still in ground rehearsals in October 2026, and nothing reusable is in service.
SpaceX from Kennedy Space Center and Cape Canaveral in Florida and Vandenberg in California, plus Starship from Starbase in Texas. Arianespace from the Guiana Space Centre at Kourou, French Guiana, at 5°3′ north, which ESA says is ideally placed for launches into geostationary transfer orbit.
SpaceX flew 165 Falcon launches in 2025. Ariane 6 flew 4 times in 2025 and had flown 9 times in all through 9 Oct 2026; Arianespace says its aim is to reach 9 to 10 launches a year as soon as possible.
