It took several missions during 1943 to actually get it.

 

on the last two 1943 missions, we took damage, including hull damage, and attained a mission rating of two in each.

And so, it continues to play out in the US Pacific portion of SH4 that a conning tower upgrade requires multiple, consecutive missions with damage incurred and a mission rating greater than 1. It seems, and I stress seems, that a mission rating of three disqualifies the upgrade. Twos and ones along with consecutive missions with some hull damage seem to cause the upgrade.

Next upgrade is August 1944 and it appears to be just a paint job.

i think i have this figured out.

August 5, 1944. last two missions we took hull damage. this mission, which just ended, successfully, we took hull damage and were awarded a two for the mission and we received the fourth and final conning tower upgrade to the Porpoise. my apologies for not capturing the upgrade screen. for some reason ctrl+f11 did not work this time. stupid game.

anyway, the US tower upgrade seems to require at least two preceding missions with hull damage and a mission rating of one or two but not three.

i intend to move on to another boat class and keep trying to solidify the requirements for a tower upgrade for US boats.
