Hi Alan,
AE479C is listed as F-15 Tactical, but showed callsign G20142, so should be HH-60M 08-20142. This also fits in with the sequence of other H-60s.
And on the topic of P-8 tactical codes, it seem like the entire block from AE660C to AE68AB are allocated to them. I have seen dozens in that block that are 100% P-8 and dozens more that are almost certainly the same, with nothing else that I have seen in that range.
Thanks,
Mike
