Ingame, a ship equipped with both a Sonar and Depth Charge will have a 15% damage boost against enemy submarines.
This bonus only applies once per ship (i.e A second pair of Sonar/Depth Charge equipped on the same ship will NOT gain another 15% boost)
Equipping a Seaplane Tender with a Depth Charge along with a Seaplane Bomber will increase damage against subs.
- Green : Outstanding
- Yellow : Above average
