[KaleunMarco]

Career Start December 1941 in Marivales driving a Sargo class boat.
there are three conning towers available:
original, SargoConningEarlyWar
mid-42, SargoConningMedWar
early-43, SargoConningLateWar


it took sixteen missions to get the conning tower upgrade.
mission ratings were a mix of ones and twos, with two threes, just for a bit of excellence.
upgrade took place August 23, 1943 after mission #16 and we received the SargoConningLateWar kit.
my apologies for not capturing the upgrade screen.

not sure why it took sixteen missions. we took almost no damage for the first fourteen missions and then took damage the last two. on number fifteen, we took 68% hull damage, and on sixteen we took enough equipment damage such that some of it was not repaired during the mission. i suspect that the upgrade MAY be related to the damage as well as the missions. MAY being the operant word.
