Fire and radiation-resistant materials; domestic sovereign EVA baseline; ~30m RMB cost reported
China's first domestic EVA — Zhai Zhigang, Shenzhou VII 2008
Limited operational cadence; not a mature fleet product; imported Haiying suit flew alongside as backup
"Pragmatic dual-track approach — import to reduce mission risk while demonstrating domestic capability simultaneously"
Validates China's sovereign EVA technology transition path; Feitian Gen-1 is to China what BERKUT was to the Soviets
Suit lifespan initially limited to 15 EVAs over 3 years; exceeded in operations before upgrade to 20 EVAs/4 years D/E series
→ Track cost-per-EVA, turnaround time and anomaly-free hours as primary KPIs once a suit enters fleet operations
"Rescue suit discipline must be kept separate from EVA product line — do not overbuild IVA with EVA objectives"
"Once a suit becomes a fleet asset, lifecycle economics and telemetry matter more than peak performance figures"
"Lunar suit must be treated as a new architecture branch — not an incremental Feitian derivative — due to dust, terrain and thermal differenc…"
