The USS Gudgeon SS-567 was a Tang Class fast attack submarine launched in 1952.
The SS-567 model has inner and outer torpedo doors. The propeller axis is centered for each prop making animation easy. The mast extends and retracts into the sail as it would have for surface and submerged operation. The instruments can also be extended and retracted individually.
The file is organized and named appropriately so any object you want to move, animate or destroy can be easily found.
The model is painstakingly researched and built on declassified construction blueprints. I hope you have as much fun playing with it as I did making it.
