On boats of the USN in the Pacific during this period, who was responsible for actually providing the data fed to the TDC? The capitain, the watch officer, the "weapons officer" (did USN boats have such a position?), some combination of the above? How did the data acquisition role(s) differ from surfaced to submerged? How many links in the command chain were there from data acquisition to data input?
Also, any recommended source readings for any of the infos above would be much appreciated!

:hmm:
cheers
