There were also smoke floats . A barrel filled with chemical and when lowered into the water it reacted and caused a white smoke . Could we have a new kind of depth charge , one that stays floating for X amount of time and emits smoke . ie: smoking while floating and stops when sunk , same as a ship i suppose . So i guess the scenario would be that the dd has an extra type of depth charge . This depth charge stays floating for X amount of time and then sinks . I am on the surface amongst a convoy and smoke barrels/depth charges are letting off smoke on the surface stopping me from seeing all the ships thru the periscope . I would nt want too many though , i guess the depth charges have a controller that adjusts time between throwing . Maybe only in medium or large size convoys and randomly , not every encounter . Just a thought , no idea if it is possible . I think this would work well with wolf pack attacks as well . I could imagine seeing a convoy in the distance covered in smoke .
