I suspect that navies are no longer viable as weapons platforms, but are still viable as force projections that can move across water. Since we don’t yet have aircraft of comparable size and weapons/personnel capacity that can loiter and be on patrol without refuelling for days or weeks on end, we need to rely on navies to be the platforms our forces operate from. Their current design is a holdover and needs reworking to adapt to new combat environments, but I doubt we’ll see them vanishing any time soon due to a lack of adequately functional replacements.
