If there was a P-3 sniffing around Hugo's butt, it probably looked more like this one:

Or this one, which got rammed by an Chinese jet

Yep, that’s the most likely Electra P-3, EP-3E ARIES II or derivative, the ones with the radar domes. But aren’t these now used for drug boat searching. So maybe Hugo has a drug boat flotilla?

But the whole 60s era Elctra airframe is mostly obsolete, there are far better modern aircraft now in service for surveillance. Maybe they gave some of them to the DEA ...
