 ====13-Shi Carrier-based Dive Bomber====
-Development of the D4Y Suisei started as the ''{{Annotation|13-Shi|13th year of the Showa reign, 1937}} Carrier Dive-Bomber'' in the Yokosuka Naval Air Technical Arsenal after the Imperial Japanese Navy Aviation Bureau issued an order for a dive-bomber with two main requirements: have a larger range than enemy carriers and their planes, and the ability to shake off interception fighters chasing them.

-The overall design of the 13-Shi was to include electrical-driven hydraulics ranging from landing gear, flaps, and bomb-bay doors, which would make it the first Japanese carrier-based plane to have a bomb bay. The fuselage was narrowed down to just the diameter of the engine and with reference to the DXHe1; the radiator and air-cooler were flush with the bomb bay to minimize air resistance and have a smooth underside. In order to balance the aerodynamic aspect and bomb bay, the main wing size was kept to a minimum in order to reduce induced drag and achieve higher speeds. To eliminate the need of folding wings, the wingspan was reduced to 11 m, matching Japanese carrier elevators. Additionally, a semi-integral fuel tank was implemented to carry a large amount of fuel required for long cruising distances.

Additionally, a semi-integral fuel tank was implemented to carry a large amount of fuel required for long cruising distances.
-But with all these measures in pursuit of high top speeds, the wings were simply too small to operate with the short take-offs and landings required for carrier planes, resulting in various designs, such as a semi-Fowler type flap that covered 60% of the wing span, and the ailerons and air brakes to be used as take-off/landing flaps. Even with that design employed, it would only be usable loaded on large, high-speed carriers of the Shōkaku class or better.

-On November 1, 1940, the first 13-Shi prototype was built and was equipped with the AE2A ''Atsuta 11'' engine (licensed DB 600G). But due to engine malfunctions it was simply discarded and swapped out for the AE1A ''Atsuta 21'' (licensed DB 601) which pushed the 13-Shi with a reconnaissance loadout to 552 km/h at 4,750 m, which was the highest speed of any naval aircraft for its time. On top of that, the operational range was recorded at 3,780 km. There were a total of 5 prototypes built eventually.

 On October 21, 1941, the 1st Carrier-Division, which was preparing the attack on Pearl Harbour before the outbreak of the Pacific war, sent a request to the Aviation Bureau to increase the number of [[A6M2]]s and 13-Shi's to be produced for combat on-top of attaching a new reconnaissance plane.
-The Navy did agree that it needed a new, high-speed recon plane to replace the [[B5N2|Type 97 carrier-based attack bomber (B5N)]] used in recon-role and [[Aichi E13A1|Type 0 Reconnaissance Seaplane (E13A)]]. With the vision of making a variant of the 13-Shi in a reconnaissance role, an order of 40 recon variants was made in November of 1941. Prototype airframes No.2, 3 & 4 were already remodeled into reconnaissance planes with cameras equipped in the bomb bay. It took more than half a month to arrive to forward units and didn't end up being used in the opening wave of the Pacific War.

During the battle of Midway, it was one of the planes that spotted the US Carrier Fleet, but due to radio malfunction, had to report back directly to the sister-ship Hiryū, as Soryū together with the other plane had already been struck on its return. Later in the battle, Hiryū was sunk as well sinking with the last frontline deployed recon prototype.

-On October 21, 1941, The 1st Carrier-Division, which was preparing the attack on Pearl Habour before the outbreak of the Pacific war, sent a request to the Aviation Bureau to increase the number of [[A6M2]]s and 13-Shi's to be produced for combat on-top of attaching a new reconnaissance plane.
+On October 21, 1941, the 1st Carrier-Division, which was preparing the attack on Pearl Harbour before the outbreak of the Pacific war, sent a request to the Aviation Bureau to increase the number of [[A6M2]]s and 13-Shi's to be produced for combat on-top of attaching a new reconnaissance plane.
 The Navy did agree that it needed a new, high-speed recon plane to replace the [[B5N2|Type 97 carrier-based attack bomber (B5N)]] used in recon-role and [[Aichi E13A1|Type 0 Reconnaissance Seaplane (E13A)]]. With the vision of making a variant of the 13-Shi in a reconnaissance role, an order of 40 recon variants was made in November of 1941. Prototype airframes No.2, 3 & 4 were already remodeled into reconnaissance planes with cameras equipped in the bomb bay. It took more than half a month to arrive to forward units and didn't end up being used in the opening wave of the Pacific War.
-In May 1942, the already converted airframes No.2 & 3 would be deployed to the Soryū as part of the 2nd Air Squad., 1st Carrier Div. During the battle of Midway, it was one of the planes that spotted the US Carrier fleet, but due to radio malfunction, had to report back directly to the sister-ship Hiryū, as Soryū together with the other plane has already been struck on its return. Later in the battle, Hiryū was sunk as well sinking with the last frontline deployed recon prototype.

-On August 15, 1942, Airframe No.5 crashed in a test flight and concluded that the airframe had to be repaired and strengthened as it would be insufficent to be used as a dive-bomber, the strengthening of the airframe didn't interfere with the flight performance of the plane.

-After frontline evaluation and last recon modifications, the reconnaissance variant would formally be adopted as the '''Type 2 carrier-based reconnaissance plane (D4Y1-C)''' and began deployment at the end of 1942, which would operate relatively well and was well received by its crew.

 ====(D4Y) Suisei====
 From June 1943, the 13-shi was finally ready after getting an improved airframe and prepared for mass production and would be officially adopted (under new naming regulations) as the '''[[D4Y1|Suisei 11 (D4Y1)]]''' and would see its debut combat at the Solomon islands in the latter half of 1943.
-In May 1943 the first '''[[D4Y2|Suisei 12 (D4Y2)]]''' with the improved Atsuta 32, which offered 1400 hp over the 1200 hp the Atsuta 12 and was easier to maintain, was ready. But with the lack of rare metals such as nickel, lack of skilled workers, and shortage of tools, the production of the Atsuta 32 delayed the deployment of Suisei 12s, with the result of stacking numbers of "noseless aircrafts" (lacking engine) lining up outside the factory. As a breakthrough countermeasure for lacking engine production, in December 1943, roughly half a year after the first Model 12, the '''[[D4Y3 Ko|Suisei 33 (D4Y3)]]''' arrived, equipped with the Mitsubishi MK8P Kinsei 62 air-cooled radial engine, which was far more reliable and had a relatively large supply, solved the logistical nightmares of the licensed DB 601. This breakthrough simultaneously solved the same problems of the Army which dealt with the DB 601 (As the Kawaski Ha-40) in its [[Ki-61 (Family)|Ki-61]]s with the exchange for the Mitsubishi Ha-112, which would evolve the plane into the [[Ki-100]].
