The VII B
served well but soon war conditions and a few unforeseen problems demanded further
improvement.
The type VII C was born, based on the earlier type VII's, earned knowledge, skill
and facts of war duty.
The VII C really proved to be an outstanding multi-purpouse boat.
Therefore it became the most produced type and used for a variety of missions
throughout WW II.The VII C received a large
number of individual modifications to gain even further improvement - for war operations
and experimetal use.
