ArianeGroup has initiated studies to increase the deployment frequency of the Ariane 6 heavy launcher, aiming for a stable rate of nine to ten missions per year starting in 2027. The company is also evaluating the technical possibility of adapting the rocket for manned spaceflight to reduce Europe’s strategic dependence on third parties. Key challenges include securing investment for solid propellant supplies.

However, technical issues involving the rocket’s turbopumps, which regulate liquid propellant pressure, are expected to impact the launch schedule. These anomalies may necessitate a reduction in planned launches for 2026 and 2027 while production line inspections are conducted. Despite these setbacks, the European Space Agency (ESA) maintains long-term goals to increase orbital launch frequency, targeting 12 Ariane 6 launches per year by the end of 2029.

## Timeline

### 2026-09-23: Ariane 6 technical issues may delay European space launches

Technical issues with Ariane 6 turbopumps may delay European space launches in 2026-2027, though ESA still targets increased launch frequencies by 2029.
