Need some help for testing things

Hey out there,

i need to test some things with late game equipment, and therefore i would need a mission to play with a late war u-boat, radar (if available), latest torpedos (mix of different ones would be great) and such things. Is there someone who has such a mission or is willing to build one for me? I am not familiar with the mission editor, thats why i am asking.

Regards and thanks,
