I think it's worth mentioning that the current design of this SH4 simulator is a result of having not fully committed to this being a 100% submarine simulator only. The original idea was to have interchangeable interior features and the option to convert this simulator for use with other Naval simulations, surface ships, like Destroyer Command and Dangerous Waters. It's a compromise that resulted in somewhat random and generic features.
For example by changing the periscope to a gun sight the simulator could be the Main Battery Director on a Fletcher class destroyer. Or, the CIC on a modern frigate in Dangerous Waters.
