The Elco PT boats were constructed from 1940 to the end of the war in several variants. They were generally faster and better at sea keeping than the Higgins PT boats and were built in greater numbers.

PT boat armament varied greatly from the description given here. Some carried depth charges for antisubmarine work. A number were converted to gunboats by landing the torpedo tubes and installing a number of cannon and machine guns in their place.
