The KUTA family includes the KG-66/66A and KGR-66 devices and NOBLEMAN refers to the KGV-68. These devices, along with the KGR-68 and KGV-68B, are used to secure weapon systems, aircraft telemetry, and data link encryption applications at test ranges. Additionally, with prior National Security Agency (NSA) approval, KUTA/NOBLEMAN units can be used for remotely staffed and unstaffed, high-risk, data link encryption applications on a case-by-case basis.

The KUTA/NOBLEMAN family is interoperable with the KG-67, KG-135, and SO-66 (Mode B only),and accepts key via the AN/CYZ-10, KOI-18, KYK-13, or KYX-15A. It is certified to encrypt/decrypt up to SECRET; however, two devices can be used in an upgrade configuration to achieve a higherlevel of classification. KUTA/NOBLEMAN units are UNCLASSIFIED controlled cryptographic item(CCI) when unkeyed. When keyed, their classification equals that of the key installed.

Specifically, the  KGR-68 is a ground-based fixed-plant decryptor for weapons system testing and telemetry decryption. The KGR-68 can decrypt data at rates up to 10 Mbps. It accepts standard paper tape key via a KOI-18 or KYK-13. The KGR-68 will retain key for at least 30 seconds during power interruptions. This device is used as telemetry decryption in weapons testing. It is approved for use at all classification levels.
