Do you mean
https://en.wikipedia.org/wiki/USS_S-42_(SS-153) ??
Specifically the "S-42 (SS-153)" part? Because no, they did not "name" submarines back then. During the "V Class" builds, they were still numbered, but received "names" shortly after. In the case of the S-42, the "S" denotes the clase, the "42" denotes the number of the boat in that class. The "SS-153" notes the hull number of the submarine of all submarines, so S-42 was the 153rd submarine built by / for the US.
