DESCRIPTION/FUNCTION

The KW-46 is a simplex system designed to provide communications security (COMSEC) for the Fleet Broadcast System. The KW-46 consists of the TSEC/KWT-46 transmitter and KWR-46 receiver. The KWR-46 is a low-level device that performs on-line decryption of digital message, record, and data traffic received over the fleet broadcast system at data rates from 50 bps to 9.6 kbps in asynchronous, stepped, or synchronous modes. The KWR-46 uses a continuous synchronization pattern situated directly in the transmitted traffic. The KW-46 will process up to and including TOP SECRET information. The KWR-46 is used for over-the-air transfer (OTAT) of crytographic material to support KG-84A/C use. The KWR-46 also supports North Atlantic Treaty Organization (NATO) Broadcast, the Navy Standard Teleprinter (NST), low frequency (LF)/high frequency (HF) R-2368 receiver equipment, and the High Speed Fleet Broadcast (HSFB). The KWR-46 is used on ships; the KWT-46 is located ashore.

Unkeyed KWR-46 equipment is classified CONFIDENTIAL. Keyed KWR-46 equipment assumes the classification level equal to that of the keying material used. Electronic key fill of the KWR-46 will only be accomplished through the utilization of the General-Purpose Tape Reader KOI-18/TSEC and AN/CYZ-10, DTD.
