Ariane 64 to make maiden launch with four boosters.

The Ariane 64, a four‑booster version of Europe’s Ariane 6, is scheduled to make its maiden launch from Kourou to deploy 32 satellites for Amazon Leo. Engines and stages were built and tested across Europe and assembled in French Guiana ahead of the flight.

Workers in France completed final work on engines and components as the Ariane 64 prepares for its first flight. The rocket, a four‑booster configuration of Ariane 6, is set to launch from Europe’s spaceport in Kourou to carry 32 satellites for Amazon Leo. Teams at ArianeGroup sites in Vernon and Les Mureaux handled engines and main‑stage assembly, while the upper stage was prepared in Bremen. The build and test work involved many European suppliers and strict security and testing procedures. Key details: - The mission is the maiden flight of the Ariane 64, the four‑booster version of Ariane 6, and is scheduled to deploy 32 Amazon Leo satellites. - The Vulcain 2.1 engine is produced and tested at the Vernon site; engines undergo full‑power test cycles before final assembly. - Major components are built across Europe—Bremen for the upper stage and Les Mureaux for the main stage—with contributions from more than 600 subcontractors and support from 13 ESA member nations. - The four solid boosters burn about 142,000 kilograms of propellant in just over two minutes and substantially increase lift compared with the two‑booster Ariane 62. - The mission is expected to last about one hour and 50 minutes, with satellites released in pairs near the end of the flight. - ArianeGroup says it plans several launches this year and is researching technologies to enable partial reuse of launcher components. Summary: The flight represents a step toward increased lift capacity for Europe’s Ariane 6 program and aims to deliver a commercial broadband constellation segment. The launch is scheduled from Kourou in the coming days, and European teams completed final assembly and testing before shipment; Undetermined at this time.
