Can somebody help me with this please.

Join the Submarine Builder's Discord listed in the 2nd post of this thread. They have a ton of helpful information about subs.

If you're just starting to build your fleet, don't worry about the special builds for now. It's going to take a while to level up your subs and unlock all the sectors.
