Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

History

Nicknamed the the "Judy" by allied pilots, the D4Y1 at the beginning of the war was one the fastest planes in all of the Pacific.

The D4Y1 was a carrier based dive bomber. Powered by a 1,200 hp "Aichi AE1A Atsuta V12" engine. The D4Y1 was modeled after the German He 118 with the engine being modeled after the DB 601 which was used in the BF110. Due to the Japanese Navy requiring an extreme range for the aircraft, it was designed without any armor or self sealing fuel tanks to lighten the plane so it would use less fuel. The lack of armor and protection decreased the weight, making them extremely quick and nimble but fragile if taking enemy fire. Combined with the unreliable engine the D4Y1 would see many upgrades in the following models adjusting many of the flaws.

In 1943 with the introduction of the F6F Hellcat, the D4Y's became a sitting duck. Where as with the F4F Wildcat, the D4Y's could just outrun them, the F6F would catch them with ease. During the "Great Marianas Turkey Shoot" a single F6F pilot Alexander Vraciu would shoot down 6 D4Y's within minutes. 400 Japanses planes would be shot down that day, but a D4Y did land a direct hit on the battleship USS South Dakota.

The D4Y's would become one of the most iconic planes the Japanese Military would use during World War 2.

Only a single complete D4Y1 survives today, located at the "Yasukuni Jinja Yūshūkan shrine" in Tokyo it can be seen completely restored.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
