Career Start January 1943 in Brisbane driving a Gar class (follow-on to Tambor Class) boat.
All other boats "UpgradeClass" are the same as the Gar, zero.
there are four conning towers available:
Original - TamborConningEarlyWar
Mid-42 TamborConningMedWar
1943 - TamborConningLateWar
1944 - TamborConningElite
it took twelve missions to get the conning tower upgrade.
mission ratings were a mix of ones and twos, with one three, just for a bit of excellence.
upgrade took place July 1, 1944 after mission number twelve and we received the TamborConningElite kit.
We took almost no damage for the first several missions and then took damage the last two. on number eight or nine, we took significant equipment damage and some hull damage, and on twelve we took equipment damage again but no hull damage. when we reached port, we received the upgrade.
