Subs got longer as time progressed, for example, Germany's first U-boat (U1) was derived from a batch of subs bound for Russia during the Russo-Japanese War in 1904; those were about 139 feet in length. WWII US Navy Gato class subs were about 311 feet in length. By the time of the cold war, atomic subs were as long as WWII battleships...600 feet long!
they can be in different sizes such as being long or short or huge and small
Nuclear Submarines can stay almost indefently for them it is a question of Stores (food). Diesel Submarines are really not designed for under ice operations. AIP Subs can stay submerged for prolonged periods depending on the amount of Liquid Oxygen it has.
Germany made its own submarines and had been doing that since the days of WW 1, long before Hitler.
The submarines in WW2 are different from now. I have done research and back then submarines were easily sunk and were ran differently ! How were they ran differently ? Back then in WW2 the submarines used, were smaller ... They were ran by Diesel engines which allowed them to high surface speed and long range, but underwater it was very difficult and the speed and range wasn't the same from out of the water.
Modern nuclear submarines can work (or patrol) for 3 months or more.
