Yeah, I used to work in SIGINT for the Navy Security Group back in the 80s as a crypto-linguist. I don’t use the acronyms because too many people on FR don’t know what they mean.
Most of the stuff up top on this ship must look very familiar to you.
I think I see a couple of “Huff-Duff” (World War II slang for HF Direction Finder) antennas too. I’m sure you have antennas for radio navigation like LORAN and others too. I’m an amateur radio operator so this interests me too. You probably have antennas, radios, scanners and so on that take you from “DC to light” (ELF to EHF and beyond) and everything in between like longwave thru UHF.
