You guys are right, historically very few u-boats had a red hull.
I'm just trying out several versions with red, grey, and a dark blue hull. What I'm more concerned with is the camo.
No worries guys, I can do several versions with all types of schemes, very easy to do. I'll post more pics of several versions here in abit.
Snafu,
No prob. Lemme take a look at her and see what I can do.
