Yokosuka K5Y

Overview

The Yokosuka K5Y (九三式中間練習機, Kyūsanshikichūkanrenshūki; Type 93 Intermediate Training Aircraft, whose Allied reporting name was "Willow") was a two-seat unequal-span biplane trainer that served in the Imperial Japanese Navy during World War II. Due to its bright orange paint scheme (applied to all Japanese military trainers for visibility), it earned the nickname "aka-tombo" or "red dragonfly", after a type of insect common throughout Japan. A K5Y of the Kamikaze Special Attack Corps 3rd Ryuko Squadron was credited with sinking the destroyer USS Callaghan on July 28, 1945, the last US warship lost to kamikaze attack during the war.
