While most Short seaplanes are known by their Admiralty Type Number, the Short 320 derived its name from its 320hp Sunbeam Cossack engine. Designed to carry a 1000lb Mark IX torpedo, but like most seaplanes it spent more time in long-range reconnaissance and anti-submarine patrols. The arrangement of the armament was unusual: the pilot sat in the back but the observer was provided with a turret level with the upper wing, allowing 360° fire at the penalty of having to stand in order to fire.
They were used out of Taranto and Malta and out of the US Naval Air Station at Killingholme. Forty were still on hand at the Armistice, when they were declared obsolete.
