This rotor cipher machine was introduced by the National Security Agency in 1952 and was one of the standard cipher systems for the US Army and Navy and NATO until it was taken out of service in 1983. The KL-7 consisted of the KLB-7 base unit containing the motor, generator, and electronics, and a rotor spindle designated KLK-7, with 8 (Pollux) or 12 (Adonis) rotors, each with 36 contacts on either side, which were connected irregularly in pairs by wires inside.
