When you can’t fly low like your predecessor then you have to develop costly new weapons to make up for the shortfall. HAAWC has been in development for about 9 - 10 years now and still has a ways to go.

So let me see if I understand this...

...they have to be close to the sub to detect it, but they want to attack it from far away?

This was discussed several years ago. Winged glide-torpedoes are the result of a basic design flaw with the P-8. The P-3 was designed to get down and dirty with subs, right up to the 200 feet above the ocean 60 degree turn MAD-trap. You (we) flew rings around the sub at ocean-top level getting repeated MADMEN and then dropped a torp down the guy's chimney. Very hot and heavy.

Then came the 737 variant P-8. Turboprops? We don't need no stinkin' turboprops. It's all jets all the time! Of course jets burn two or three times as much fuel at low levels as turboprops. Hmmm. Can't fly at low level. So, can't use MAD or any other low-level tactic. No problem! We'll drop torps from 20,000 feet, glide them down to where we guess the sub will be in 5 or 10 minutes and ... oops! Where'd it go?

The P-8 story is one of basically abandoning ASW in favor of ASuW or over-the-horizon stuff. Enemy subs are going to wipe-out our carriers quickly in the next shooting war.

This is huge, most submarines attempt to evade by detecting low flying aircraft over the water.

No warning with this sucker. Spooky.....
