Anecdote acknowledged. While I know we're a far cry from the proficiency we had during the CW, I think you're casting an awfully wide net with your declarative statement. Curious if you've had a recent experience observing a P-8 crew at work.
P8 computing power and systems make submarine detection a lot easier. Big plus there. Thanks to things like the red stripes, HONA, 18 month home cycles and desert deployments, until recently you’ve had operators who got their first on top experience on a ASW centric deployment at their 10-15 year mark and some only on their second ASW deployment in 20 years with 10+ years in betwen. Entire squadrons took their planes to 5th fleet for a decade + without ever even trying to find a submarine.
As we know ASW is based in science but there’s a bunch of stuff that goes into it that makes it more of an art form. A lot of institutional knowledge and basic skills atrophied due to lack of exposure so in many ways crews were re-inventing the wheel during their infrequent ASW deployments. A 1-2 weeks squadron turn over isn’t really enough to impart all the knowledges about finding submarines in an AOR... airspace constraints, rules of the road, sure but that’s admin when it comes to ASW. It’s going to take a few more years of rotating squadrons consistently back through ASW deployments for that knowledge and experience base to build back up.
