Great work!
Is the azipod at the aft of the sonar a joke?
It's a pop-out auxiliary propeller for harbor tugless maneuvering, it pops back into the hull when not in use.
These are not uncommon; Perry had a similar system.
I do wonder if it's drawn at the right scale, though. Looks like about a 1000hp-class system, compared to two 300hp for Perry.
