Yokosuka R2Y Keiun
The Yokosuka R2Y Keiun (景雲, cirrus 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 used coupled engines driving a single propeller and also featured a tricycle undercarriage. 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.
