The photos below were taken from a United States Navy submarine USS Trepang, March 1971 some where between Iceland and Jan Mayen island.
My first thought when I saw these photos was it had to be some sort of balloon or blimp used in target practice by the submarine. I’m not sure? What do you think? Do you have any information about this case that could be used to prove or debunk?
