High Speed Transport - World War II Service

World War II Service

As newer and more modern destroyers began joining the fleet some of the old ships were assigned to other duties such as tending seaplanes, laying or sweeping mines, or for a newer innovation in modern warfare, carrying fully equipped troops for assault landings as fast transports.

In the Guadalcanal Campaign, neither side enjoyed the overwhelming local naval and air supremacy which ensured victory in every other amphibious operation of the war. This necessitated an increase in the number of high-speed transports, hybrid warships which combined the functions of transports and destroyers. The concept of the high-speed transport embodied sufficient armament for the ship to defend herself against smaller warships and to support the troops she carried with sufficient speed to enable her to outrun more heavily armed ships.

APDs performed arduous service. They transported troops to beachheads, served as escorts for transports and supply vessels, conducted anti-submarine patrols and survey duties, operated with Underwater Demolition Teams and commando units, performed messenger and transport duties, conveyed passengers and mail to and from forward units, and were involved in mine sweeping operations. They were attacked by submarines, surface ships and aircraft (including kamikazes), and many were damaged or sunk.
