It increases your ship's ASW (Anti-Submarine Warfare) stat and allows it to wreck enemy submarines like no one's business. While your DDs and CLs don't need any depth charges to attack subs, without them the damage they deal against anything but the weakest sub is going to be just scratch damage most of the time.

Furthermore, equipping both depth charge and sonar to the same ship gives an additional ASW bonus.
