Torpedoes like the one being launched in this photograph allowed relatively small warships like destroyers to damage or destroy much larger vessels.

In the interwar period, Canadian destroyer crews trained and prepared to carry out their assigned task of countering enemy surface raiders threatening shipping in Canadian waters. They tested torpedoes and other weapons systems in exercises conducted yearly in the Caribbean with British naval units. This photograph, aboard an unknown and probably non-Canadian ship, may have been taken during tests or trials, since the man standing at right is wearing civilian clothing.
