Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Too early to adopt

Why
Compelling modeled 50% fuel-burn case and strong tier-1 backers, but it is pre-first-flight with an unsolved propulsion path and heavy pre-validation capex — far from any adoptable maturity.
Next
Re-evaluate after the 2027 full-scale demonstrator first flight and any measured (vs modeled) fuel-burn data; watch for a committed production engine selection
