The Yokosuka R2Y Keiun (景雲 - "Beautiful Cloud") was a prototype reconnaissance aircraft built in Japan late in World War II.

Design and development

Commissioned for the Imperial Japanese Navy after the R1Y design was cancelled due to its disappointing performance estimates, the R2Y borrowed from the German pre-war Heinkel He 119 in its use of coupled engines driving a single propeller. It also featured a tricycle undercarriage giving it an appearance similar to the Messerschmitt Me 509.

Completed in April 1945, the prototype made a short flight on 8 May, but was destroyed in a US air raid only a few days later, thus ending development.

A proposal was also made to develop the R2Y into a turbojet-powered light bomber by replacing its piston engines with two Ishikawajima Ne-330s. Designated the R2Y2 Keiun-Kai, the prototype was begun but never completed.
