Submarines from Space
As was posted a few months ago, you can look at Razorback from space using Google Earth.
Most of the other submarine museums are also easily found, but so are a number of modern, active duty submarines.
For example, here is a German Type 206 Submarine in drydock in Kiel, Germany:
Here is a picture of what appears to by an Akula-class (Type 971) nuclear powered Russian attack submarine, in port near Polyarnyy, on the Kola Peninsula.
You can find submarines of almost every nation, including American submarines, if you know where to look... Sometimes, the pictures have been intentionally "blurred", but other times, it's amazing the amount of detail you can see.
