[Missing Name]

I tried to start one of my new campaigns with a VIIB. No dice - after several patrols of no upgrading, I bought the IXB. The only reason I don't upgrade beyond a regular IXC is the dive time. 37 seconds is just at the limit of what I can accept.

But yeah, I love the IX's. The IXBs were the most successful boats of the war.

As for 1941: Be glad RADAR is not a threat. Your deck gun will start seeing less use if you are sane. Convoys will be harder to attack. Airplanes are getting better. Your lucky numbers are 37, 105, 20, 9 and 22.
