Airdales and nukes only bubbleheads captured USN design and leadership positions long ago eliminating diesel boats and fire power opposition opting for a more defensive posture just as the Democratic Party has been misdirected into Socialism.
I would be in favor of costal diesel submarines with AIP, they are quieter than nukes, can stay down for long periods, have demonstrated that they can sneak up on surface fleets and are much cheaper than nuke attack subs, leave the nukes for the blue water and make a fleet of these for costal defense
