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

[edit] Design and development

Commissioned for the Imperial Japanese Navy after the Yokosuka 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 arrangement that was possibly influenced by the Messerschmitt Me 509.

Completed in April 1945, the prototype made a short flight on May 8, 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, little progress on the design was made before the end of the war.
