Notes

1. AN/BQH-7A was a surface ship version of the same bathythermograph
2. Before AN/CRC designated Cryptographic Radios, the first "C" meant "Air Transportable"
3. Many different sources say a smaller follow-on system, AN/MST-T1(V), is called "Mini-MUTES"
4. In reference to the AN/TPS-3, Wikipedia article SCR-602 (AN/TPS-3) says the frequency is 176–202 MHz (170–148 cm) instead of 590–610 MHz (51–49 cm) claimed by the MobileRadar.org site cited in this list
