Since facetious comments seem be the order of the day -the answer to your first question is probably as many as the RNZAF do. The USCG has sunk more submarines than the NZDF has.
I'm struggling to see the logic behind the tremendous faith people have in Boeing's ability to create an ASW platform from an airliner, with very little experience at MPA development, and at the same time dump manure on the concept of Lockheed extending the capability of a proven surveillance platform, when Lockheed has a hell of a lot more experience at MPAs than Boeing does.
Do you know what the P-3 is based on? If Lockheed can build a MPA around a relatively unsuccessful airliner Electra (150 sales) then Boeing should have no trouble doing it with a 737 (over 6000 jets). However Boeing won't beat the MPA to commercial ratio as Lockheed sold 3 times as many P-3s as they did Electras.
