During the Cold War, one submarine would frequently attempt to follow another by hiding in its baffles. This led to the practice of "clearing the baffles", that is, turning to observe the blind spot and detect any followers. Related maneuvers included the "Crazy Ivan", a hard turn to clear the baffles and position the submarine to attack any followers, and "Angles and Dangles", a five-hour process of rapid direction and speed changes to ensure that all items aboard were properly secured for hard maneuvering and would not fall or shift suddenly, producing noise that the enemy could detect.
This was depicted in both the book and movie called Hunt for Red October.
The torpedo ended up turning back on itself and blowing up the one that shot it.
Much like the Russia Collusion is turning back on the ones that started it.
