IVAActive🇨🇳
Shenzhou IVA Suit
Designation: Shenzhou Cabin Suit
The suit Yang Liwei wore when China became the third nation to independently send a human to space — based on Russia's Sokol KV-2.
About This Suit
The Shenzhou IVA suit is China's intravehicular pressure suit, structurally derived from the Russian Sokol KV-2 through a technology transfer arrangement between China and Russia in the 1990s. Manufactured domestically by the Chinese Academy of Space Technology, it was worn by Yang Liwei on Shenzhou 5 on October 15, 2003 — when China became the third nation in history to independently send a human to space. The suit connects via umbilical to Shenzhou's capsule life support and inflates in emergencies. While closely based on the Sokol KV-2 architecture, it has been adapted for Chinese taikonaut anthropometrics and updated with each Shenzhou generation. It remains in active use on Tiangong space station missions.
