That’s nice. I have a few rhetorical questions for you.

So how long can a turbofan engine stay on a low altitude station vs. a jet engine?

Answer: Much, much longer.

So is the wing loading better for a jet engine than a prop engine?

Answer: No, not really, they are two different variables, the P-3 does just fine and if one needs more weapons on station, just take another P-3 with you.

So how good do the avionics need to be for a four engine turbofan airplane?

Answer: Not very good at all.

So is the range of the P-3 too low?

Answer: No, it’s just fine and better than the P-8 thank you very much.

So the range is longer without refueling, the time on station is longer, it carries plenty of weapons, costs less, etc., etc. etc.

You’re right about one thing, you don’t know. You’ve struck out on everyone of your points. Tell us again how the P-8 is going to accomplish the same mission but this time do it with numbers and with a cost comparison.

The P8A is a more fully capable aircraft and can be readily converted to a number of missions. It's faster, flies higher and covers more area with less travel than the P3.

Simple lesson, higher altitude enables the ability to 'see' further.
Also, the overall maintenance is similar to a number of systems already in place, so parts, logistical supply, and training is refined and simplified keeping operational costs lower.

But thanks for playing. A-hole
