So explain to me if we have more aircraft carriers than the rest of the world’s navies combined, more guided missile destroyers than the rest of the world’s navies combined, more nuclear submarines than the rest of the world’s navies combined, more amphibious helicopter ships, more landing ships, more auxiliary ships, more of just about anything else you can name, and taking into consideration that most of the rest of the world’s navies are on our side, then why do we need 350 ships? Are we expecting all the other navies except China and Russia to go out of business?
History has proven that we cannot rely on other nations. I do not rely on my neighbor for my defense.
Why only count nuke subs? Diesel/electric subs sink ships quite easily.
We do not have more than the world combined, except in carriers and large warships. One reason for that is the need for PROJECTION of force. We have to be able to keep sea lanes open for our economy. Small warships, missile boats, subs, etc. are quite good at closing strategic waterways.
You know nothing of the requirements to keep sea lanes open, or the consequences of regional control by bad actors.
