History and use
Developed for the Russian Navy in the early 1950s, the GKS3 mixed gas recirculating helmet was capable to depths of sixty (60) to two hundred (200) metres. The helmet had a large neck ring in which the injector system was mounted. The diver carried a metal container on his back that held the Natrium Hydroxide (sodascorb) to clear the exhaled air of CO2.

When the GKS3 helmet was developed its injector was attached to the same place on the helmet as it was with the earlier SKD prototype, right in front of the diver's mouth. American helmets had the injector at the right back of the helmet, just in front of the CO2 absorbent canister. German Draeger helmets have the injector placed in the backpack, just after the CO2 absorbent canister. In 1953 the first GKS3 was taken into service with the Russian Navy, but the earliest manual on GKS3 is dated 1954. Shortly after the GKS3 was succeeded by a modified version known as the GKS3-M.
