Do American Submarines ever submerge

[Platapus]

I guess I was spoiled by my VIIB being able to hit Periscope depth pretty fast. But in SH4???

Crikey! the war will be over by the time my Submarine gets to Periscope depth. It is so bad that I use TC just so I don't fall asleep.

I swear, I can give the command to dive to periscope depth at the same time the Japanese factory is just finishing up constructing an Airplane. By the time the Airplane gets to its base, undergoes testing, gets a new pilot assigned, the pilot gets certified, goes out on his first patrol he will STILL catch me on the surface!

Sheeesh, my last patrol, I gave the order to crash dive and before we went under I had two Petty Officers retire!

So in reality, were the German boats able to dive that much faster than American boats?

Well I am going to dive now, it is August 1942. With any luck I should be at periscope depth about the time they sign that little piece of paper on the USS Missouri.
