The KGR-96 is a receive-only, digital data decryptor that provides security for the Tactical Receive Equipment (TRE) (AN/USQ-101 [V]), which is used to copy the Tactical Data Information Exchange System (TADIXS)-Bravo and the TRE and (TRAP) Data Dissemination System (TDDS) broadcast on fleet flagships and major combatants. The KGR-96 can be controlled and monitored either locally, using front panel controls and indicators, or remotely, using signals that are input and output on rear panel connectors. Additionally, the KGR-96 features include local or remote key filling, power transient protection, and self-test. It is interoperable with the KG-46 and the KGT/R-62.
The KGR-96 requires two different keys, unique to each piece of equipment, for input by the user before processing traffic. Keying/rekeying is accomplished through the front panel fill connection or remotely through the rear panel connector (only one key may be remotely refilled). The rectangular shaped KGR-96 is designed for mounting in an MT-4841/U, which can mount two KGR-96s. The equipment is deployed on major naval shore stations, major naval surface ships, and submarines; is certified to receive up to TOP SECRET level traffic; and when unkeyed is classified SECRET No Foreign Nationals.
