The Yokosuka P1Y Ginga (Galaxy) was a twin-engine, land-based bomber developed for the Japanese Imperial Navy in World War II. It was the successor to the Mitsubishi G4M and given the Allied reporting name 'Frances'.
The first flight was in August 1943. Nakajima manufactured 1,002 examples, which were operated by five Kokutais (Air Groups), and acted as land-based medium and torpedo bombers from airfields in China, Taiwan, Marianas, Philippines, Ryukyu, Shikoku, and Kyushu. During the last stages of the war the P1Y was utilized as a kamikaze aircraft against the United States Navy during the Okinawa Campaign in Operation Tan No. 2.
A night fighter version, the P1Y2-S Kyokko (Aurora), with Mitsubishi Kasei engines, was equipped with radar and Schräge Musik-style upward-firing -- as well as forward-firing -- 20 mm cannon. A total of 96 were produced by Kawanishi, but due to inadequate high-altitude performance against B-29s, many were converted back to Ginga bombers.
