Yokosuka K5Y

what is it?

The Yokosuka K5Y (九三式中間練習機, Kyūsanshikichūkanrenshūki; Type 93 Intermediate Training Aircraft) was a twin-seat unequal-span biplane trainer aircraft designed by the Japanese aviation manufacturer Kawanishi Aircraft Company and the Yokosuka Naval Air Technical Arsenal. It was flown by the Imperial Japanese Navy (IJN) 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. Its Allied reporting name was Willow.
