ESA confirms it has shelved planned Ariane 6 Block 3 upgrade after funding shortfall

ESA confirmed it will not pursue the Ariane 6 Block 3 evolution, including the ICARUS lightweight upper stage, after member states funded only EUR 145.94 million of the EUR 304.4 million sought at the CM25 ministerial, citing "no programme need".

Reported Editor-read European Spaceflight, 20 August 2026

What it does not test. This does not show Ariane 6 will get no future upgrade at all, only that the specific Block 3 evolution has no current programme mandate.

How this item counts. No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0. Planned upgrade dropped for lack of funds; current Ariane 6 capability unchanged. European Sovereignty Index
