Diesel room in the next compartment!
The diesel engineer's station. Next to it are tools and machines for making repairs at sea.
Serious Das Boot vibes from this one!
Just forward, an odd little compartment, the compass room. Most space in it taken up by the huge gyrocompass.
Looking forward from the compass room to the control room. Note that unlike many museum ships, D-2 has all the circular hatches preserved, and you have to duck like a submariner to go through them (not great for those of us with low mobility, but a thrill for a healthy sub fan
)
Looking aft from the compass room into the diesel room. (Das Boot vibes again!)
