This device is an encryptor/decryptor for ground and space communications developed in the early 1970s. The KG-46 encrypts plaintext digital data for transmission from space to a ground station and deciphered digital cipher data received from the ground station for use on the spacecraft. This particular one never made it into space having been destroyed when the Titan-34D missile exploded at launch.
