There is a U boat sunk off the shore here where I live. It was sank in WW2 and has been moved a couple times. Its now a dive site, there are videos of it on you tube.
The local museum has a torpedo on display and other bits like chunks of the experimental rubber coating they used on the U boats to help block sonar.
That is some high level model building there. Love how he did the explosion and the ripples on the water surface.
Here is a link to the museum. I work right next to it.
14:50 on this video shows the torpedo. The Island was a navy torpedo test site until 1945. 3:37 & 10:38 you just barely get a glimpse of the marine dock where we load bulk petroleum on ships and barges. Been working there 24 years.
Its amazing how close the germans were to our shore lines and the gov never let the people know it. They were on the west coast as well.
