The D4Y1 is a highly agile and speedy aircraft, it can turn fight anything it wishes, even [[Spitfire (Family)|Spitfires]]. It gets a bomber airspawn, which allows the D4Y1 to outclimb all the fighters, but '''be sure to select the right airspawn''', because it gets a carrier spawn by default on pacific maps. The only issue with the performance of this aircraft arises at high altitudes, where it is left without a supercharger.

The D4Y1 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 D4Y1'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.Spec

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.

Description

GarageImage D4Y1.jpg


The D4Y1 Suisei (Comet), nicknamed Judy by the Americans, is a rank II Japanese bomber with a battle rating of 2.0 (AB/RB) and 2.3 (SB). It was introduced in Update 1.75 "La Résistance". It is a very strong ground attack aircraft, and thanks to its high speed and agility, it can make a great fighter. This is your typical Japanese dive bomber, which has excellent ground pounding capabilities, as well as fighter hunting abilities. All these gifts come with downsides, as the D4Y1 is unable to carry rockets or torpedoes, unlike the D4Y2, and has poor defensive armament compared to the D4Y3. It has an Atsuta Atsuta 21 12-cylinder inline engine, which provides excellent power, but unfortunately has overheating issues.

General info

Flight performance

The D4Y1 is a highly agile and speedy aircraft, it can turn fight anything it wishes, even Spitfires. It gets a bomber airspawn, which allows the D4Y1 to outclimb all the fighters, but be sure to select the right airspawn, because it gets a carrier spawn by default on pacific maps. The only issue with the performance of this aircraft arises at high altitudes, where it is left without a supercharger.

Usage in battles

The D4Y1 in Fiji

The D4Y1 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 D4Y1'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.Spec

Specific enemies worth noting

  • CW-21 - The CW-21 poses a significant threat to the D4Y1, as it can out-turn, out-climb, and outclass the D4Y1 in every conceivable way. Its armament will shred through the D4Y1, and your plane would be a sitting duck. Now, your gunner can be of some use. Since the CW-21 is a very fragile aircraft, your gunner can set it afire, thus giving you the upper hand. But never under any circumstance attempt to go near this plane, as your gunner is only a last resort.
  • He 100 D-1 - Much like the CW-21, this aircraft will outclass you in every way. Your turret will once again come in handy, as it will surely damage its cooling system.

Pros and cons

The D4Y1's defensive gunner, which can help pick seagulls off of your six

Pros:

  • Nimble, can out-turn certain enemy fighters
  • Fast for its BR, can outrun anything it wishes, save the CW-21 and He 100
  • Its speed forces the enemy to tail behind your gunner, giving you a chance to shoot at the approaching fighter with your turret
  • Turret covers all upwards angles and covers a decent part of the rear
  • Has an additional 400 rounds in the machine guns, making ammo count less of an issue
  • 500 kg bomb will destroy pillboxes, bridges, tanks, and destroyers
  • Has Airbrakes
  • Armament is nose mounted
The D4Y1 has great turret coverage, it covers a high angle of attack from boom and zoomers.

Cons:

  • The Type 92 gun has a low rate of fire and bad accuracy, which can make it hard to aim if an enemy fighter comes your way
  • Significant delay in bomb drop
  • Exposed gunner
  • Not good for bombing bases
  • Offensive armament does not provide enough firepower to down bombers, but it can still nwork wonders on the many fighters you will face, namely the F2A, I-15/16, and Hurricanes
  • Fragile, no armour
  • Engine overheats easily, it isn't a traditional Japanese radial engine
  • No torpedoes

History

D4Y1 in flight

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 Bf 110. Due to the Japanese Navy requiring an extreme range for the aircraft, it was designed without any armour or self-sealing fuel tanks to lighten the plane so it would use less fuel. The lack of armour 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. Whereas 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 Japanese 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.
