Editing Ariane 5 (section)

=== Solid boosters ===
Attached to the sides were two P241 (P238 for Ariane 5G and G+) [[solid rocket booster]]s (SRBs or EAPs from the French ''Étages d'Accélération à Poudre''), each weighing about {{cvt|277|t|lb}} full and delivering a thrust of about {{cvt|7080|kN}}. They were fueled by a mix of [[ammonium perchlorate]] (68%) and aluminium fuel (18%) and [[hydroxyl-terminated polybutadiene|HTPB]] (14%). They each burned for 130 seconds before being dropped into the ocean. The SRBs were usually allowed to sink to the bottom of the ocean, but, like the [[Space Shuttle Solid Rocket Booster]]s, they could be recovered with parachutes, and this was occasionally done for post-flight analysis. Unlike Space Shuttle SRBs, Ariane 5 boosters were not reused. The most recent attempt was for the first Ariane 5 ECA mission in 2009. One of the two boosters was successfully recovered and returned to the Guiana Space Center for analysis.<ref name="FranceScience">{{cite web|url=http://www.france-science.org/spip.php?article399#3-ARIANE-5-ECA-BOOSTER-RECOVERED|title=France in Space #387|publisher=Office of Science and Technology Embassy of France in the USA|url-status=dead|archive-url=https://web.archive.org/web/20090125213207/http://www.france-science.org/spip.php?article399#3-ARIANE-5-ECA-BOOSTER-RECOVERED|archive-date=25 January 2009}}</ref> Prior to that mission, the last such recovery and testing was done in 2003.{{Citation needed|date=January 2022}}

The French [[M51 (missile)|M51]] [[Submarine-launched ballistic missile|submarine-launched ballistic missile (SLBM)]] shared a substantial amount of technology with these boosters.<ref>{{cite news|title=French Navy SSBN 'Le Téméraire' Test Fired M51 SLBM In Operational Conditions|author=Xavier Vavasseur |date=12 Jun 2020|url=https://www.navalnews.com/naval-news/2020/06/french-navy-ssbn-le-temeraire-test-fired-m51-slbm-in-operational-conditions/|website=navalnews.com|access-date=March 27, 2023}}</ref>

In February 2000, the suspected [[nose cone]] of an Ariane 5 booster washed ashore on the [[South Texas]] coast, and was recovered by [[Beachcombing|beachcombers]] before the government could get to it.<ref>{{cite web |url=http://www.foxnews.com/etcetera/022900/space.sml |archive-url=https://web.archive.org/web/20010224100038/http://www.foxnews.com/etcetera/022900/space.sml |date=29 February 2000 |agency=Associated Press |publisher=Fox News |title=Government Loses Unidentified Floating Object |archive-date=24 February 2001 }}</ref>
