The European Space Agency confirmed that it is no longer considering the Ariane 6 Block 3 evolution, saying there is “no programme need or justification” for the upgrade at this time. The decision follows a study that indicated Ariane 6 Block 2 will be the rocket’s final major version, which required a rework of a planned Enceladus mission that assumed Block 3 capabilities. An ESA spokesperson said the near‑term roadmap includes the already introduced P160C boosters and a lighter Vulcain Aft Bay to increase performance and competitiveness, with the Astris orbital transfer vehicle expected around 2029. The agency also noted that the ICARUS lightweight upper stage was not approved at the November 2025 Ministerial Council (CM25), with funding for the Ariane 6 adaptation envelope falling short by €158.46 million. ESA added that Ariane 6 may continue to evolve if new mission requirements arise and that human spaceflight is being examined as part of developing a future European crewed launch capability.
