Under the Joint Electronics Type Designation System (JETDS), all U.S. military radar and tracking systems are assigned a unique identifying alphanumeric designation. The letters “AN” (for Army-Navy) are placed ahead of a three-letter code.[1]
The first letter of the three-letter code denotes the type of platform hosting the electronic device, where A=Aircraft, F=Fixed (land-based), S=Ship-mounted, and T=Ground transportable.
The second letter indicates the type of equipment, where P=Radar (pulsed), Q=Sonar, and R=Radio.
The third letter indicates the function or purpose of the device, where G=Fire control, Q=Special Purpose, R=Receiving, S=Search, and T=Transmitting.
Thus, the AN/SPQ-11 represents the 11th design of an Army-Navy “Ship-mounted, Radar, Special Purpose” electronic device.[1][2]
