KG-57

This device was developed to replace the KGR-29 for space communications. It began development in 1975 and was used until 1995. It reduced the size, weight, and power consumption even more than the KGR-29 for satellite communications security equipment, making it the smallest produced encryption devices for satellites. It was finally replaced in 1994 by the NSA-developed ASIC (Application Specific Integrated Circuit) that are used on satellites command and authentication systems today.
