If your asking where the scenarios are for these E-boat models - I don’t know.
In general , The SHII Mission or scenario files are stored in C:\Program Files\SSI\Silent Hunter II\Shell\Scenarios
The scenario files are file type “.sdf”They are text documents (script) that can be opened with notepad, changed, saved , and run in the game.
For an introduction on editing or creating new scenario files see : “Silent Hunter II Scenario Hand Edit Guide” near the bottom of this page :
