DescriptionRussian Complete Sokol KV-2 Pressurized Spacesuit. A complete crew "rescue" suit including helmet, avionics, gloves, and boots, as made by NPP Zvezda for Soyuz cosmonauts. Markings on the gloves indicate that they belonged to Cosmonaut Anatoly Artsebarsky and had flown to the Mir space station. This suit was likely only used in training This model suit was first used on Soyuz T-2 in 1980 and is still in use today during launch and descent.

Rarely offered complete with boots and headset. Fine condition with definite signs of use and wear.
Early Soyuz spaceflight carried no pressurized suits for use during ascent and descent. The three man crew of Soyuz 11 died during re-entry because the spacecraft depressurized. The government investigating committee recommended that pressure suits be worn during the critical portions of their missions and the NPP Zvezda company was given the contract to develop this series of suits. The Zvezda website gives the following description of the Model KV-2 suit: The SOKOL-KV-2 is a lightweight suit with a soft integral helmet, having a visor sliding up/down. The mass of such a suit does not exceed 9-10 kg. This spacesuit is designed for the most dangerous phases of the mission in terms of cabin depressurization hazard: in the ascent phase, during docking and in the re-entry phase. In case of emergency, a cosmonaut can quickly don the spacesuit in the spacecraft without any assistance. In case of cabin depressurization, the cosmonaut in a sealed spacesuit can work in the cabin for 2 hours. When the spacesuit is not sealed, it is ventilated with cabin air. In case of spacecraft cabin depressurization, pure oxygen (instead of gas mixture) is supplied to the spacesuit from the oxygen source. This source is also used by the on-board system, which maintains the cabin gas mixture composition.
