A job today's Navy doesn't want

 Strategic defense.  (Gee, didn't have a choice in my day)

"...a Kanyon //russian mega nuke torpedo// self-detonating at the Golden Gate Bridge would completely obliterate San Francisco, killing 1.3 million across Northern California and injuring another 1.1 million..."

The Navy has some unique responsibilities with regard homeland defense.  It is the sole service likely to even attempt detecting and countering a Russian 'strategic' torpedo.

With the described parameters of the Kanyon torepdo, the number of US attack submarines in service now and likely in the future, and given the retirement of the B-57 nuclear depth bomb, a depth bomb derivative of the nuclear B-61, delivered from a ship based SH-60 (or land based P-8) would appear a hard requirement.

But, that appears to be a  problem for today's diverse, and largely neutered, Navy (which I last noted on 3 days ago ... https://nexttobagend.blogspot.com/2022/05/todays-navy.html ).

“Having served on a nuclear-capable surface ship in the late 1980s, that mission does not come without a cost. There is a significant amount of attention that has to be paid to any platform that carries that type of weapon in terms of training, in terms of sustainability, in terms of reliability, in terms of the force’s readiness to be able to use and be able to conduct that mission,” Gilday said.

Call me a non-believer Admiral, but, 'diversity' and community service alone ain't gonna stop this thing.  I know it's kinda' hard acquiring and maintaining ASW competency, and a couple of NDBs onboard messes with port calls, BUT if it's not the Navy's job - whose is it?.
