The D4Y3 is an overall improvement to the D4Y series, it has improved defensive armaments, better bomb loads, and a new radial engine which keeps itself cool. All these advantages give it a 3.0 battle rating, which unfortunately outclasses its armament, rendering it less effective at the fighter role than the [[D4Y1]] and [[D4Y2]]. The D4Y3 is still a capable fighter despite these disadvantages, due to its high speed and turn time. It will find Spitfires excellent targets, as you can out turn spitfires and your guns will sooner or later knock out the pilot or rip off a wing, and sometimes damage the tail control. The D4Y3 is also strong in the ground attack role. Its three 250kg (500lb) bombs will have no trouble destroying light pillboxes, medium tanks, and bases. The machine guns can also destroy AAA, and light trucks.

The D4Y3 is an excellent example of a multirole aircraft, as it is an excellent ground attack aircraft, fighter, and bomber. Since you get a bomber airspawn, you can drop your bomb on a base and then start to engage the many fighters below you. You should have no problems engaging them, as long is you keep your speed up and your energy high. One key thing to note is that you don't need to use your defensive turret to shoo away enemy interceptors. You can easily out turn any interceptor at that BR. Besides the fighter role, ground attack is the D4Y3's natural method of play. The 500kg bomb will be excellent for destroying Pillboxes, and you can use your Rifle Caliber machine guns to destroy any soft target you please.

Description

GarageImage D4Y3 Ko.jpg


The D4Y3 Ko is a rank II Japanese dive bomber with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.71 "New E.R.A". The D4Y3 is an overall improvement to the D4Y series, it has improved defensive armaments, better bomb loads, and a new radial engine which keeps itself cool. All these advantages give it a 3.0 battle rating, which unfortunately outclasses its armament, rendering it less effective at the fighter role than the D4Y1 and D4Y2. The D4Y3 is still a capable fighter despite these disadvantages, due to its high speed and turn time. It will find Spitfires excellent targets, as you can out turn spitfires and your guns will sooner or later knock out the pilot or rip off a wing, and sometimes damage the tail control. The D4Y3 is also strong in the ground attack role. Its three 250kg (500lb) bombs will have no trouble destroying light pillboxes, medium tanks, and bases. The machine guns can also destroy AAA, and light trucks.

General info

Flight Performance

The D4Y3 has superior performance to the first two D4Y aircraft, as it has a radial engine, which won't overheat in combat conditions. The radial engine also has a less pronounced radiator, resulting in less drag. The D4Y3 is a capable turner, but bleeds energy easily. It is recommended to do hard turns in combat situations.

Survivability and armour

The D4Y3 ditches self sealing fuel tanks and armor for speed and agility. As such, the D4Y3 should be treated like any other Japanese aircraft: with the utmost caution

Armaments

Offensive armament

Main article: Type 97 navy (7.7 mm)

The D4Y3 Ko is armed with:

  • 2 x 7.7 mm Type 97 navy machine guns, nose-mounted (400 rpg = 800 total)
D4Y3 in a steep dive

Suspended armament

Main articles: Navy Type 97 Number 6 (60 kg), Navy Type Number 25 Model 2 (250 kg), Number Type 2 50 Model 1 GP(SAP) (500 kg)

The D4Y3 Ko can be outfitted with the following ordnance:

  • Without load
  • 1 x 250 kg Navy Type Number 25 Model 2 bomb + 2 x 60 kg Navy Type 97 Number 6 bombs (370 kg total)
  • 3 x 250 kg Navy Type Number 25 Model 2 bombs (750 kg total)
  • 1 x 500 kg Number Type 2 50 Model 1 GP(SAP) bomb (500 kg total)
  • 1 x 500 kg Number Type 2 50 Model 1 GP(SAP) bomb + 2 x 60 kg Navy Type 97 Number 6 bombs (620 kg total)

Defensive armament

Main article: Type 2 navy (13 mm)

The D4Y3 Ko is defended by:

  • 1 x 13 mm Type 2 navy machine gun, dorsal turret (250 rpg)
The D4Y3 about to destroy a medium tank

Usage in battles

The D4Y3 is an excellent example of a multirole aircraft, as it is an excellent ground attack aircraft, fighter, and bomber. Since you get a bomber airspawn, you can drop your bomb on a base and then start to engage the many fighters below you. You should have no problems engaging them, as long is you keep your speed up and your energy high. One key thing to note is that you don't need to use your defensive turret to shoo away enemy interceptors. You can easily out turn any interceptor at that BR. Besides the fighter role, ground attack is the D4Y3's natural method of play. The 500kg bomb will be excellent for destroying Pillboxes, and you can use your Rifle Caliber machine guns to destroy any soft target you please.

The radiator can be kept at 0% in climbs, the D4Y3 will manage to keep cool. Open the oil radiator and radiator to 10% when leveling off, to avoid overheat after prolonged periods of time. Propeller pitch should be kept at 90-100%, and the stage two of the supercharger should only be activate at 3000 meters (10000 feet).

The bomb loadouts should be a priority for this aircraft, and the frontal machine guns should also be a module of importance. The compressor, Engine, and Injection will prove useful. After researching the engine mods, rush the Suitability modules. Only then should you tackle the turrets. The Wings Repair and Fuselage repair should come last.

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.
