Short Type 166

Though it was designed as a torpedo-bomber, the Short Seaplane, Admiralty Type 166 was used primarily for the traditional seaplane-patrol role. Like the Short Type 135, it used the powerful (for the time) 200hp Salmson radial engine. Unlike the 135, the 166 used king posts to brace the larger top wing rather than diagonal struts. Five were on hand on the Ark Royal in late 1915, and another twenty were built in 1916 by Westland Aircraft Works.

Many served in the Eastern Mediterranean and the last two were retired in mid-1918.
