Anybody with even a minimal knowledge of military hardware would immediately see that this was not a US submarine.

Rather, the deck slopes off gradually to a bow that is pointed at the tip of the boat. It has been that way for the past thirty years, at least.
Also, this thing looks like a bathtub toy compared to the much larger US nuclear powered subs.
