I don't think they fly the P-8 in the same flight regiment as the Orion used to fly. There's no MAD sensor, and it doesn't have the range at low levels to consistently hit the deck.

ASW has been starved of funds and attention for so long. The P-8 is really an MPA, not so much an ASW platform. It can do some of the job, but compared to the S-3/P-3, it makes some sacrifices. The nice thing is that it can transit an area quickly.
