Due to technical limitations, this article uses an unusual title. It should be called TSEC/ prefix.
Most U.S. government-approved, in communications security (COMSEC) equipment has designations in the form TSEC/KG-99, in which TSEC/ (note slash) is purely an identification for a designation system, not an abbreviation. The designation system is under the control of the National Security Agency (NSA). It complements the AN/ system used for general military electronics, which does reserve certain of the letters in the AN/ system are reserved for NSA use. While the designation system codes are quite complex and still contain special cases, the basic structure is:
The next numbers indicate a main model number within the series, followed by a bewildering and inconsistent set of version levels, alternate configurations, etc. Sometimes, what may seem an incremental improvement gets an entirely new model number, while a radical change may get a version change only. In other words, grasp the general principles of the system, but know that you will have to examine a specific system to understand its designation nuances.
