An Early and Rare Russian VKK-2 partial pressure suit-functionally identical to the David-Clark T-1 model US equivalent and probably inspired by it. The Russian VKK-2 suit is an early equivalent of the US Air Force T-1 partial pressure suit, used by pilots flying in the upper atmosphere. Russia actively examined and investigated many American technological solutions to various aerospace medical problems and the VKK-2 suit is therefore closely patterned after the original western mechanical partial pressure suits designed and developed by Dr. Henry, since it was an effective means of providing aircrew high altitude defense against lowered atmospheric pressure. The latter VKK-4 and VVK-6 suits (used in the MiG-21 and other aircraft with the GSh-4 and GSh-6 helmets) were improved and modified versions of the earlier VKK-2, corresponding to the US MC-2, MC-3, and MC-4 partial pressure suits. Great suit for your collection. This suit is in excellent condition, unused, size 1.
