List of military electronics of the United States: M–Z

For a general summary of the JETDS nomenclature system, see List of military electronics of the United States. For a full description of the JETDS system, see Joint Electronics Type Designation System.

This subpage 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.

Due to page size considerations, the full list was split into sub-pages. The list on this page only shows designations where the first letter after AN/ is between M and Z. For all designations between A and G, please see List of military electronics of the United States: A–G.

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

Notes

1. Many different sources say a smaller follow-on system, AN/MST-T1(V), is called "Mini-MUTES"
2. In reference to the AN/TPS-3, Wikipedia article SCR-602 (AN/TPS-3) says the frequency is 176–202 MHz (170.34–148.41 cm) instead of 590–610 MHz (50.81–49.15 cm) claimed by the MobileRadar.org site cited in this list
3. Not to be confused with SEACOM (African cable system) and SEACOM (Asian cable system) communication systems, or Rafael Advanced Defense Systems's trademarked SeaCom naval communications suite
