Joint Electronics Type Designation System

PEQ-2, PAQ-4, PAS-13, PRC-119 (SINCGARS), PRC-77


Ever wonder why some military hardware has these funny names?

It’s a electronics designation system designed by the Army/Navy during WWII called JETDS (Joint Electronics Type Designation System).

Each JETDS device has a three letter code designating its use, prefixed with A/N and ending with the series/model number. Some examples:

A/N PAS-13
Army/Navy, Human Portable, Invisible Light, Detecting – Search, Model 13

A/N PEQ-2
Army/Navy, Human Portable, Laser, Combination Purposes, Model 2

A/N TVS-5
Army/Navy, Ground Transportable, Visual/Visible Light, Detecting – Search, Model 5

A/N PRC-77
Army/Navy, Human Portable, Radio, Communications (two way), Model 77

Intuitive, right? ;-)
