**What it does not test.** This does not disclose the new contract's monetary value or confirm the engine will fly operationally; the demonstrator test is not due until 2027.

**How this item counts.** No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0\. ArianeGroup/ESA contract advances existing kick-stage engine; pre-flight, no shift. [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/)
