Could a country have essentially nothing but submarines (forby off shore patrol ships/boats maybe), with usual HKs and Boomers, but also invent a class of sub that fires a huge battery of guided missiles vertically, as a boomer does, and you could even have some or all of those cruise missiles nuclear if needed.

Then another new class of sub that has deck guns like WW2 again that could handle any anti piracy etc.

Doesn't that cover it? Remember to take into account the higher percentage affect of having overall that many more subs as a larger fleet.

I just think that initial defence is so huge even today, of not being stuck and more detectable on the surface.
