Using Commander you can get an IXB as early as Dec 39 sailing out of 2nd Flotilla.

To change your renown go on a short patrol (out of the dock even then straight back) and save the game.

Now go to C:\Documents and Settings\usually your name\My Documents\SH3\data\cfg\Careers\your Kaleuns name

Open up the Patrols_0 CFG and third line from the bottom is Delta Renown....change that to any value you want.
