The Göteborg class revived Sweden's practice of holding back part of a torpedo salvo. One pattern launched three weapons from the aft mount and two from the forward mount, saving the centre torpedo in the forward mount for a later track. Another delayed a following group by about 30 to 90 seconds, allowing the first tracks to make the later weapons harder to spot. These were local small-force tactics intended to complicate evasive manoeuvres, and their effectiveness could vary. The single-book and translation caveat attached to the earlier account of this tactic also warrants caution here. Sweden could at times field more destroyers than Germany, although the treatment of large fleet torpedo boats makes that comparison debatable.

Göteborg salvos reserve torpedoes to catch an evasive target
Göteborg-class firing patterns use delayed torpedoes and obscured tracks to make evasive manoeuvres less predictable.
