Fails WP:GNG. A few passing mentions found, but nothing more (and nothing that comes from WP:RS, either). The article is completely unsourced too, so I don't think it would be a good idea to merge it with secure telephone, contrarily to the editor who deprodded it. A redirect could be an option however.

Keep. Search Google Books and open library finds quite a few information security/cryptographic books have talked about, perhaps the two best examples are:
Information Security Management Handbook Volume IV, Harold Tipton, 2019. gbookBy the 1960s, the KY-3 came to market as one of the first practical voice encryption devices.
A Brief History of Cryptology, J. V. Boone, 2005. archive.org link p. 83 and later. The KY-3 voice encryption system was still too large and power-hungry for graceful tactical field use and was not intended for that purpose, but it did gain acceptance in a wide variety of office-like applications. It was specified in detail by NSA engineers and produced by the Bendix Corporation.
I'll try my best to incorporate those and a few other references to the article soon, if no one else does it before. Skynxnex (talk) 20:56, 1 September 2022 (UTC)[reply]
