STU-III - Secure Telephone Unit, 3rd Generation.
STU-IIIs are the standard secure telephone for the U.S. Government, used by people at all levels: the President and his Cabinet, Congress, the military, civil agencies, law enforcement, government contractors and research institutions.[citation needed] The major goals of the STU-III program were to provide an affordable secure telephone that fit conveniently on a desk, was easy to use, and worked over the public telephone network. The first STU-IIIs became available in 1987. Since then, over 300,000 STU-IIIs have been fielded. Continual improvements have enabled the STU-III family to evolve to support many applications. They provide security for voice conversations and data communications such as faxes, computer-to-computer file transfers, and video.
