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° fire at the penalty of having to stand in order to fire.
