In daylight, destroyer groups could emerge from smoke, launch, and disappear before another group attacked from a different bearing. The resulting concentrations forced a target to solve several torpedo tracks instead of reacting to one obvious mass. Communications and force integration made that coordination more feasible than it had been for early torpedo boats. The method increased tactical pressure on the enemy, but it also raised the command burden on the attacking formations.

Mass and manoeuvre in Second World War torpedo attacks
Destroyers could use smoke and coordinated attacks from several bearings to make one massed torpedo threat much harder to evade.
