text: Still, depth charges had two principal disadvantages: First, they required the attacking ship to overrun the submarine, meaning that for a few moments the ship's own propeller and movement sounds would blank out the U-boat noises; second, the depth charges, pre-set to explode at the sub-marine's estimated depth, would always explode and this further masked any submarine sounds.
