Question: When the U-boat is at 200 meters depth, and even deeper, it is attacked with depth charges. We can see the charges explode close to the hull. Was it really possible to set charges to explode at this depth? In 1943 the US developed depth charges that could be set to 180 meters.

Answer: The Royal Navy Depth Charge Mark VII could be detonated as deep as 270 meters, this is after 1940 but before 1943. This is below the crushing depth of the Type viic U-boat from the movie.
