Ariane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) was called the EPC (Étage Principal Cryotechnique — Cryotechnic Main Stage). It consisted of a 5.4 m (18 ft) diameter by 30.5 m (100 ft) high tank with two compartments, one for liquid oxygen and one for liquid hydrogen , and a Vulcain 2 engine at the base with a vacuum ...
Rockets from the Ariane rocket family have accumulated 260 launches since 1979, 248 of which were successful, yielding a 95.4% success rate. The recently retired Ariane 5, flew 82 consecutive missions without failure between April 2003 and December 2017, but suffered a malfunction during flight VA-241 in January 2018, causing its two satellites to reach an incorrect orbit, and reducing their ...
Ariane flight VA256 was an Ariane 5 rocket flight that launched the James Webb Space Telescope (JWST) into space on 25 December 2021. [3] It was 2021's final Ariane flight, its most valuable payload to date, and the 256th Ariane mission. The launch was described by NASA as "flawless" and "perfect". [4]
For example, an Ariane 42P is an Ariane 4 with two solid-fuel boosters. An Ariane 44LP has two solid, two liquid boosters, and a 44L has four liquid-fuel boosters. Ariane 5 rocket at Le Bourget Air and Space Museum, Paris. Ariane 5 is a nearly complete redesign. The two hypergolic lower stages are replaced with a single LH2/LOX core stage.

Ariane 6 was conceived in the early 2010s to be a replacement launch vehicle for Ariane 5, and a number of concepts and high-level designs were suggested and proposed during 2012–2015. Development funding from several European governments was secured by early 2016, and contracts were signed to begin detailed design and the build of test articles.
