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).

Pros and cons
Pros:
- Extremely agile for a dive bomber aircraft and is very useful in naval arcade battles as it can avoid enemy ship AAA and deliver its payload
Cons:
History
Nicknamed the "Judy" by allied pilots, the D4Y3 was feared by both troops on the ground and ships in the sea.
The D4Y3 was converted to be a land based Dive Bomber, while its predecessor the D4Y2 was a carrier based dive bomber. The removal of the tail hook and the addition of the Mitsubishi Kinsei 62 radial engine added 150 horse power while reducing weight. The D4Y3 would see 3 variants, D4Y3 model 33, D4Y3 model 33A, and D4Y3 model 33 night-fighter.
Differences between the Model 33 and the Model 33a was the A variant had the Type 1, 7.92mm rear firing machine gun replaced with an upgraded Type 2, 13mm rear firing machine gun. With the night-fighter variant being equipped with an upwards firing 20mm cannon. Only 3 night-fighters were built as the D4Y2 night fighters were being used with success with fighters already available and assembly lines already making them.
With a range of 1,400 miles the D4Y3 was perfect for the defense of the Japanese territories. Combined with its extreme accuracy in a dive it saw great success especially in the battles at the end of the war. Notably, crippling the USS Kalinin Bay and the USS Suwannee both escort carriers. Eventually they would convert the D4Y3 into a D4Y4, which was exactly the same as the D4Y3 except it carried an un-removable 800kg bomb for kamikaze attacks. Some D4Y4's were equipped with rockets to increase the speed at which the aircrafts would strike their targets increasing the damage they caused.
No D4Y3's survived the war, but a D4Y1 was reconstructed with a Pratt and Whitney R-1830 radial engine to represent a D4Y3. This plane can be seen at the Planes of Fame Air Museum in Chino, California.
