capabilities based loosely off inferences based on the following classes:
U-1 (size and speed) http://uboat.net/wwi/types/index.html?type=U+1
UC-1 (appearance) http://uboat.net/wwi/types/index.html?type=UC+I
UB-1 (number of tubes on a small boat) http://uboat.net/wwi/types/index.html?type=UB+I

[Guinness]

Experiments with the A and B class coastal subs indicate potential for the submersible boat as an offensive as well as defensive weapon. With exploring such operations in mind, the Navy commissioned the design of a much larger boat, the C-Class. At least 5 will be acquired during 1913.
