Type VII C / 41

 


 
An improved version of VII C with better armoured conning tower, stronger pressure hull (which allowed dives to some 250 m) and several other, minor modifications.
The changes were so small that therewas no major mechanical diffrence between the VII C and the VII C / 41.

The museum ship U 995 in Laboe, Kiel, Germany is a type
VII C / 41.
