  • When upgrading this plane focus on getting the payload especially the torpedo modification. This is due to the high chance Japan has to get naval maps.
  • After you've unlocked all the possible torpedoes, it is recommended that you research the flight performance modules first, as the aircraft has very little defensive and offensive capabilities.

Usage in battles

The B5N2 is a Japanese torpedo-bomber that is lacking in offensive armaments and is defended by a single 7.7 mm Type 92 machine gun at the back, which makes it lacking in defence against enemy pursuers. Its greatest weapon is not the speed to outrun enemy fighters but its maneuverability and ability to do tight turns against most enemy aircraft till help arrives from the team.

The B5N2 might lack in offensive weaponry such as machine guns and cannons but it has a great variety of payload from 60 kg bombs to 800 kg bombs and even torpedoes in its arsenal to take out ground and naval targets with. Coming with 2 different 800 kg bombs, its important to pick the one most suitable for the mission, preferably the Navy Type Number 80 Model 1 over the Navy Type 99 Number 80 AP, with the benefit that the Type Number 80 Model 1 has a better blast radius and more explosive power than the Type 99 Number 80 AP bomb which is good at taking out a single heavily armoured target. It also come with two different sets of 250 kg bombs that can be dropped one by one and are preferable when striking at two different targets than a singular 800 kg.

Against naval targets, it's most preferred to use the Type 91 Mod.2 and Type 91 Mod.3 to deal with the sailors, keep in mind to dive and get fast speed to quickly get in and out of engagement with a warship or patrolboat to minimize the risk of being shot down. But when doing a dive attack to get the speed its important to not go over the speed limit where the B5N2 can drop the torpedoes without having them explode in the water on contact which would make the attack futile.

Every enemy should be seen as a serious threat to the B5N2, as it does not have an offensive armament. The only thing the plane has when it comes to armament is 1 7.7 mm machine gun, which is not a reliable way to fend off enemies with it lacks damage and doesn't offer the best coverage, but at 1.7 it might be enough to scare off ill-armoured biplanes.

History

The Nakajima B5N2 (Allied code name: Kate) was a plane first flown in January 1937 for the Imperial Japanese Navy. About ~1149 Nakajima B5N Torpedo bombers were made for the Japanese Navy. It would see service in World war 2 and was the Japanese Navy's primary torpedo bomber for the early part of World war 2. The Nakajima B5N Torpedo bomber was credited with the sinking of three US Carriers the USS Lexington CV-2, USS Yorktown CV-6 and USS Hornet CV-8. One of the most notable pilot of the B5N is Mitsuo Fuchida, who led the first wave of aircraft during the Japanese attack on Pearl Harbor.

Although a total of 5,928 B5Ns were built, none survived the war. Two B5N's are know to exist, both made from wreckage's. One can be seen at the Pearl Harbor Memorial, it is missing it's tail, left wing, engine, canopy, and a few other parts.

In-game description

Before the advent of the B5N, Japan used the B2M and B4Y as torpedo biplanes. However, the significant limitations of biplanes were obvious, so in 1935, inspired by the monoplane A5M fighter, the Imperial Japanese Navy developed the 10-Shi torpedo bomber specification.

Nakajima and Mitsubishi participated in the competition. Nakajima decided to incorporate many new ideas in their B5N design. The prototype had a hydraulic wing-folding system so that the plane could be stored on an aircraft carrier, and Fowler flaps were used to improve stability while landing. In addition, the B5N had a hydraulic retractable landing gear system.

Although Mitsubishi also received an order for production of its own B5M torpedo bomber, the Nakajima model won the contest and in 1937 was accepted as a production model carrier-based torpedo bomber.

To create a production model, however, some changes had to be made in the prototype's design. The wing-folding system was changed to a manual one, and the flaps were replaced with conventional ones.

In 1939, the B5N2 was developed. It differed from its predecessor in its more powerful and reliable Sakae engine, which produced 1000 hp instead of the Hikari 3's 770.

At the beginning of World War II, the B5N torpedo series had no worthy competitors among Allied aircraft and made a great showing in the attack on Pearl Harbor, as well as in subsequent operations, where B5N forces sank four U.S. aircraft carriers within one year.

A total of 5,928 B5Ns were built.
