History
ZhZT-71 was developed in 1971 by NII Stali, on instructions from the technical department of the USSR Ministry of Internal Affairs. In that version of the body armor, plates were used from the most effective material at that time - OT4-1 titanium alloy. ZhZT-71 weighed up to 12 kg.In 1974, NII Stali started development of ZhZT-71M, a version that addressed several issues at once. It also had a new dampener layer 30 mm thick on the chest, and 10 on the back, made out of foam rubber Polyurethane. Weight increased to over 10 kg, due to thicker 3.3 mm plates that were used to meet the requirements of stopping buckshot rounds from shotguns.
In 1975 a vest was designed for protection against cold weapons - ZhZL-74 with a weight of 3.4 kg. Plates were made out of aluminum.
It was used by Alpha Group personnel during operation to free the hostages of Aeroflot Flight 6833.
ZhZT vest was still in service as late as 1990s.
