Arianespace Secures Seven Ariane 6 Agreements Covering Around Ten Launches as Amazon Leo, Eutelsat and International Customers Expand Order Book

(IN BRIEF) Arianespace has announced seven agreements and memorandums of understanding covering around ten Ariane 64 launches at the International Space Summit in Paris, representing Ariane 6’s largest order intake since entering service. Amazon Leo has ordered six additional Ariane 64 launches, increasing its planned total with Arianespace from 18 to 24 by 2031, following three 2026 missions that deployed 100 satellites. Eutelsat has booked two launches in 2027 and 2028 for renewal of its OneWeb constellation, while The Exploration Company’s Nyx capsule will fly on Ariane 64 under ESA’s ALADDIN initiative. Arianespace will also launch a new AscendArc-built high-throughput satellite for KT SAT in 2028, providing several hundred Gbps of Ka-band capacity. Meanwhile, MoUs with ICEYE, EnduroSat and AgenaSpace establish potential future cooperation in launch and orbital-transfer services. CEO David Cavaillolès said the agreements demonstrate Ariane 6’s growing commercial strength while supporting its parallel role in maintaining Europe’s autonomous access to space.

(PRESS RELEASE) ÉVRY-COURCOURONNES, 11-Sep-2026 — /EuropaWire/ — Arianespace has announced seven new agreements and memorandums of understanding at the International Space Summit in Paris, covering around ten future Ariane 64 launches and representing the company’s largest order intake since Ariane 6 entered service.

The agreements, concluded with customers and partners from Europe, the United States and Asia, span satellite constellation deployment, geostationary communications satellites, space transportation and future orbital-transfer services.

New commitments involving Amazon Leo, Eutelsat, The Exploration Company and AscendArc for KT SAT have strengthened the Ariane 6 launch manifest, while memorandums of understanding with ICEYE, EnduroSat and AgenaSpace establish a framework for potential future launch and in-orbit service collaborations.

Seven agreements signed during International Space Summit

Arianespace concluded the seven agreements over two days at the International Space Summit, marking the strongest commercial order intake for Ariane 6 since the launcher began operational service.

The agreements demonstrate the range of missions now being targeted by the European heavy-lift launcher, from deployment of large satellite constellations to geostationary communications spacecraft and emerging space transportation missions.

David Cavaillolès, CEO of Arianespace, said the agreements underline Ariane 6’s growing commercial momentum and ability to address a broad range of customer requirements.

He said the launcher has two complementary objectives: maintaining Europe’s autonomous access to space while competing for international commercial launch business.

Amazon Leo adds six Ariane 64 launches

One of the largest commitments announced at the Summit came from Amazon Leo, which has ordered six additional Ariane 64 launches.

The new contract increases the number of launches planned between Amazon Leo and Arianespace from 18 to 24 by 2031.

The expanded agreement follows three Ariane 6 missions conducted in 2026 that deployed 100 Amazon Leo satellites in less than five months.

The additional launches reinforce Ariane 64’s role in supporting the deployment of large satellite constellations, a segment that represents a significant share of global launch demand.

Eutelsat books two launches for OneWeb constellation renewal

Eutelsat has ordered two additional Ariane 64 launches to support the renewal of its OneWeb low-Earth-orbit constellation.

The missions are currently scheduled for 2027 and 2028.

The agreement extends a long-standing relationship between Arianespace and OneWeb. Between 2019 and 2022, Arianespace conducted 13 missions that placed 428 OneWeb satellites into orbit.

The new missions will support Eutelsat as it begins renewing and maintaining the operational capability of the constellation.

Ariane 6 to launch The Exploration Company’s Nyx capsule

Ariane 6 will also support a European space transportation demonstration through an agreement with The Exploration Company.

The company’s Nyx space capsule will fly on its first demonstration mission aboard an Ariane 64 as part of the European Space Agency’s ALADDIN initiative, short for Autonomous LEO Accelerated Demo Docking to ISS Node.

The mission expands Ariane 6’s role beyond conventional satellite deployment into emerging European space transportation services.

Arianespace sees this capability as increasingly important as European companies develop new spacecraft for cargo transportation, orbital operations and other commercial services.

KT SAT high-throughput satellite scheduled for 2028

Arianespace is also expanding Ariane 6’s commercial footprint in Asia through a mission for KT SAT.

In 2028, Ariane 6 is scheduled to launch KT SAT’s next high-throughput geostationary communications satellite, designed and manufactured by AscendArc.

The spacecraft is expected to provide several hundred Gbps of Ka-band capacity, supporting improved high-speed connectivity for underserved communities across the Asia-Pacific region.

The mission highlights Ariane 6’s ability to serve the traditional geostationary satellite market alongside the rapidly expanding constellation sector.

ICEYE, EnduroSat and AgenaSpace sign memorandums of understanding

Alongside the confirmed launch contracts, Arianespace signed three memorandums of understanding with European space companies ICEYE, EnduroSat and AgenaSpace.

The agreements are intended to explore future opportunities involving Ariane 6 launches and associated services.

The ICEYE and EnduroSat agreements create a basis for future launch cooperation, while the AgenaSpace partnership will examine potential orbital-transfer solutions involving Ariane 6.

The MoUs reflect Arianespace’s effort to broaden Ariane 6’s customer ecosystem as Europe’s commercial space sector expands into new satellite, transportation and in-orbit service markets.

Constellation deployment becomes major Ariane 64 market

The latest orders reinforce Ariane 64’s position in the growing market for deploying large satellite constellations.

With six additional launches from Amazon Leo and two missions supporting the renewal of Eutelsat’s OneWeb constellation, constellation operators represent a significant portion of the new commercial commitments.

Ariane 64, the four-booster configuration of Ariane 6, provides the performance required to deploy significant satellite payloads and is being positioned for both institutional and commercial missions.

The latest contracts demonstrate how constellation deployment is becoming an increasingly important component of the launcher’s commercial manifest.

Ariane 6 expands across multiple mission categories

The new business announced in Paris also demonstrates the diversity of missions Arianespace expects Ariane 6 to serve.

Alongside large-scale constellation deployment, the launcher will support geostationary telecommunications satellites, space transportation demonstrations and potentially new orbital-transfer services.

This broader mission portfolio is designed to enable Ariane 6 to respond to changing demand as the global space market develops beyond conventional satellite-launch requirements.

Arianespace said the combination of established and emerging mission types strengthens the commercial case for Europe’s heavy-lift launch capability.

Commercial growth complements Europe’s autonomous space access

Arianespace views Ariane 6 as both a strategic European capability and an international commercial launch vehicle.

Providing Europe with autonomous access to orbit remains one of the launcher’s central objectives, while winning international customers can strengthen its operational base and competitiveness.

Cavaillolès said the announcements at the International Space Summit demonstrate that these two objectives can reinforce each other.

A larger and more diversified commercial order book can support regular launch operations while maintaining the industrial and operational capabilities required for European institutional missions.

Global customer base continues to expand

The agreements announced in Paris span customers and partners from several major space markets.

Amazon Leo strengthens Ariane 6’s presence with U.S. commercial customers, while the KT SAT mission expands its activities in Asia.

European customers and partners including Eutelsat, The Exploration Company, ICEYE, EnduroSat and AgenaSpace further broaden the launcher’s role within Europe’s developing space ecosystem.

Together, the agreements establish a diversified pipeline covering telecommunications, Earth observation, constellation deployment, spacecraft transportation and potential in-orbit services.
