FFS Stuffy
Whilst the P8 may be adequate in peacetime.
Something more is required, when things get nasty.
Will you just answer the question that you have been asked several times in the last couple of pages; why is the range/endurance combination of the P-8 unsatisfactory? And why would anyone buy a weapons system that is "adequate in peacetime" but not when things get nasty?
The MPA version of 'Grizzly', the A400M, is tough enough and big enough, to do the job, in the FUTURE.
Except, of course that it doesn't exist. It doesn't have a weapons bay. It doesn't have ESM or RWR. Fitting a modern search radar will be an issue. And given Airbus Mil's delivery record so far, it isn't going to be an option anytime in the near or medium term.

Thus, an ENDURING fundamental requirement of a MODERN Long Range Maritime Patrol Aircraft is the need to carry out a 4-6 hour on station period, equating to 10-12 hours airborne time...wait for it.... WITHOUT AAR.
This has been pointed out numerous times, but there's none so blind as those that don't want to see........ Good luck with that!
