5305. Very-high-frequency (VHF) tactical radiotelephone circuits have proved their value in war. The following general rules are set forth for the guidance of responsible commanders in the use of such circuits in wartime:
a. They may be used for initial contact reports, emergency maneuvers, and the transmission of important information when visual means are prohibited or too slow.
b. Only a minimum of transmission should be permitted during darkness or reduced visibility.
c. Caution must be exercised in the use of plain language transmissions of vital importance which would be of value to the enemy if intercepted.
5306. Detailed instructions supplementing or modifying the foregoing general principles shall be issued by responsible commanders as appropriate and necessary, depending on the situation existing.
Note that under conditions of darkness or reduced visibility, when submarines or other vessels might be within range without being detected, use of VHF radio was discouraged.-RF

Okay. I dont want to get off on a tangent here. The only point I am trying to make is that Fleet boats with the proper conning tower configuration could make transmisssion at parascope depth. Wether they did so commonly or thier procedures in doing so are not important to my point.
