A Mine Laying U-Boat Whatever Next (Type VII D)

How about this for a dastardly and cunning idea, the Germans developed the Type VII D mine laying U-Boat. Longer than the Type VII C with a mid-section inserted carrying five static moored mine laying silos. This was a bit like modern ballistic SSBN's, except that they dropped out of the bottom of the hull and were permanently flooded being outside the pressure hull (see picture below): 

Another birthday present, stuck together and glued, I seem to be slipping into a "put it together" mode drifting away from painting and finishing things off.

North Atlantic rendezvous, a Type VII D, meets up with a Type VII C (see below):   

A game idea, a game idea, a kingdom for a decent game idea?

PS: There is no shortage of water where I live currently live as we've had above a months worth of "typical rainfall" for the season in just over twenty four hours (see above, there is usually a good two foot extra space beneath that footbridge).
