9.Conning Towers / Turms

Unlike SH3, Turmumbau (Conning Towers) cannot be upgraded manually, but are coded to upgrade on certain dates within the *.upcge files. The only U-boats that are programmed for this upgrade are the Type VIIC, Type IXB and Type IXC. This is the schedule for the different subs

Type VIIC

Turmumbau I - 1940-07-30 to 1942-06-15
Turmumbau II - 1942-06-16 to 1943-12-10
Turmumbau III- 1943-12-11 to 1945-05-15

Type IXB

Turmumbau I - 1939-07-30 to 1942-08-18
Turmumbau II - 1942-08-19 to 1945-05-15

Type IXC

Turmumbau I - 1941-01-02 to 1943-02-15
Turmumbau III - 1943-02-16 to 1945-05-15

However you will have to “earn” this upgrade, there is a condition where you have to have had at least one patrol that was considered a good patrol. IE, earn more renown then the minimum on the first patrol rating. Just so ever one understands, besides completing the primary objective of patrolling a defined area for the proscribed time, there is a “hidden” objective that requires you to sink any where from 1000 to 10000 tons pre patrol. So remember this, ever time you report in and get a new assignment you get another “hidden” objective in it.

The upgrade dates from the readme... this has me worried about my current career. Turns out I am currently in a VIIB - does that mean I am safe?
