less endurance,

That will come as a surprise to P-8 crews while they refuel in flight, something they couldn't do in a P-3.

If more than 14 hr endurance was required then the navy could have put ARF on them. I worked heavy depot on these for 11 years and they are an incredibly versatile aircraft especially after the update 3 mods. ESSI/ SSI-K was fixing the wings which was the major problem in the life expectancy. The Army actually proposed that the Air Force allow them to buy the P-3 for convoy protection due to the loiter time and Maverick capabilities.
I started out unimpressed with the airframe but after 11 years I found it to be one ugly, rugged, wonderful aircraft.
