Now the ZP5K / Z2SG-1, an entirely new class of airship which is (for some reason) lumped under the K class.
Probably 6 usable photos of this class that I could find online and a few more in the U.S. Navy Airships book (all of them grainy and blurry). Control car is similar to the N class. Note the towing sonar stowed aft.
I broke my own rule and drew panel lines on this one.
