Short Type 320

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&deg; fire at the penalty of having to stand in order to fire.

The type 320 stayed in service from 1916 through the Armistice, though never in the large numbers of the Short Type 184. They were used out of Britain RNAS stations and the Mediterranean.
