List of military electronics of the United States

This article lists American military electronic instruments/systems along with brief descriptions. This stand-alone list specifically identifies electronic devices which are assigned designations (names) according to the Joint Electronics Type Designation System (JETDS) beginning with the AN/ prefix. They are grouped below by the first designation letter following this prefix. The list is organized as sorted tables that reflect the purpose, uses and manufacturers of each listed item.

JETDS nomenclature

This is an incomplete list, which may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries. Please observe the definition of the list when adding or editing entries.

All electronic equipment and systems intended for use by the US military are designated using the JETDS system. The beginning of the designation for equipment/systems always begins with AN/, which only signifies that the device has a JETDS-based designation (or name). When the JETDS was originally introduced as the unclassified Joint Army-Navy Nomenclature System (JAN), AN represented all Army-Navy electronic equipment. Later, the naming method was adopted by all Department of Defense branches, and others like Australia, Canada, NATO and more.

The first letter of the designation following AN/ indicates the installation or platform where the device is used (e.g. A for piloted aircraft). That means a device with a designation beginning "AN/Axx" would typically be installed in a piloted aircraft or used to support that aircraft. The second letter indicates the type of equipment (e.g. A for invisible light). So, AN/AAx would designate a device used for piloted aircraft with invisible light (like infrared or ultraviolet light) sensing capability. The third letter designates the purpose of the device (e.g. R for receiver, or T for transmitter). After the letters that signify those things, a dash character ("-") is followed by a sequential number that represents the next design for that device. Thus as one example, AN/ALR-20 would represent:^[1]

• Installation in a piloted aircraft: A
• Type of countermeasures device: L
• Purpose of receiving: R
• Sequential design number: 20

So, the full description should be interpreted as the 20th design of an Army-Navy (or all Department of Defense) electronic device for a countermeasures signal receiver.

Due to the enormous number of United States and allied military electronic systems using the JETDS naming convention, the list has been split into two sublists. To ease navigation, below is a list of direct links to various tables in each sublist. The sublists are:

• List of military electronics of the United States: A–G
• List of military electronics of the United States: M–Z

NOTE: Letters E, H, I, J, L, N, O, Q, R, X and Y are not used in the first-position of JETDS nomenclatures.
