It will show based upon the date. While the JP was "ordered" into use in 22d February, 1942, getting into the field and into use took a while, but as boats rotated in, it was added, so that is the way we've done it in FotRSU. As a little side note, besides the JP being activated from the beginning in the mod (done to reduce confusion for the player), there was an oversight as to the "H" node that the subs used. Some boats have H01-H04, with the first and last being the under hull-mount, and the 2 & 3 being the deck-mounted points. However, just like with the R01-R04 nodes for radar, there was minimal consistency in their use. Combine that with various mods and the combining of the same for other mods, and some of the boats use the H04 node (Starboard head) for the mounting of the JP "T"... so you would have to use the external camera, go below, and then inside the hull, to be able to "see" the rotating JP "T"... They should be pointing to node H02... lol
