That is exactly what I thought. It dived quicker than a IID does. Not that I was complaining when the bombs started falling from the plane.
There are a number of things I want to praise.
1. The U-Boat does not look like a floating rust bucket. This is great.

2. I like the animated periscope in the conning tower.
3. I also appreciate that it can actually dive to great depths.
There are a few negative things IMO.
1. The crash dive times are fast far too fast
2. I think the battery is depleting just a bit too quick.
3. The radar doesn't retract into the housing?
Obviously there are more detailed things I have to say and will say them later but first impressions are its just what I expected of it.
