The Yokosuka D4Y Suisei (彗星, Suisei, "Comet"; Allied reporting name "Judy") is a two-seat carrier-based dive bomber developed by the Yokosuka Naval Air Technical Arsenal and operated by the Imperial Japanese Navy from 1942 to 1945 during World War II. Development of the aircraft began in 1938.

Both fleets (73 strike aircraft, 126 fighters) launched a combined raid and at least on "Judy" hiding in the clouds managed to avoid the CAP and manage a direct and fata hit on the fast fleet carrier USS Princeton.

May 19, 2019 · The D4Y4 was a variant designed for the suicide mission role and was a single-seater with the Mitsubishi Kinsei engine and an 800 kg (1,764 lb) bomb. A number were built as the D4Y2-S for the night fighter role but were not particularly successful.

Description: Single-engined carrier-based dive-bomber and reconnaissance aircraft, and land-based night fighter (D4Y2-S). All-metal construction with fabric-covered control surfaces. Accommodation: Crew of two in tandem enclosed cockpit (all versions except D4Y4) or pilot in enclosed cockpit (D4Y4).

Jul 7, 2017 · The Yokosuka D4Y Suisei (translating to "Comet" and nicknamed "Judy" by the Allies) was a capable dive bomber serving the Imperial Japanese Navy during the Second World War.

Yokosuka Type 2 Carrier Recoansn-Dive Bomber Suisei / D4Y. Nicknamed Suisei 彗星 meaning "comet". Code named Judy. Built as a replacement for the D3A Val and entered service in large numbers in 1943. Powered by Aichi Atsuta liquid cooled V-12 engine (based on Geramn Daimler-Benz DB 600G).

The Yokosuka D4Y Suisei (彗星, Suisei, "Comet"; Allied reporting name "Judy") is a two-seat carrier-based dive bomber developed by the Yokosuka Naval Air Technical Arsenal and operated by the Imperial Japanese Navy from 1942 to 1945 during the Second World War.

"Judy" was the response to a call for a two-seat long-range dive bomber as fast as the Zero. The result was the fastest dive bomber of the Second World War, which could not operate effectively from light carriers due to high takeoff speed requirements.

For the later model D4Y3 and D4Y4 series the engine was replaced, this time by the very powerful and reliable 1,560 hp Mitsubishi Kinsei 62 14-cylinder twin row air cooled radial engine. The D4Y3 and D4Y4 had an operational range of 1600 miles and a top speed of 356 MPH.
