Explanation:

Depth charges are quite literally explosives in a barrel that sink  to a set depth before exploding. They wouldn't be 100% accurate due to them tumbling as they went down into the water. You usually needed at  least a couple of Depth charges before you could knock out  a Jerry (slang word for German during world war 2, fun fact!) U-Boat submarine, and this  still applies today.
