yes you can do it. all you need is sh3 money trainer and sh3 commander. first generate 1 milion renown, set commander for spending in base at 1 day and start carriere. Return at base same day and start to change equipment on your u boot or change manny times new u boot than back to old etc... While douing that you will notice that daysand months are changing. When you reach 1944th, simply transfer to flotila with XXI u boots and take it (dont remember witch flotila is it). When you do that DONT START NEW MISSION you will stuck in 1944, simply exit the game and go back in it with sh3 commander, because you set commander that you stays in port yust one day you are back in 1939 with brand new XXI with all aquipment but only with old torpedos. hawe nice hunt herr kaleun
