Description

The B5N2 is a rank I Japanese naval bomber with a battle rating of 1.0 (AB), 1.3 (RB), and 1.7 (SB). This aircraft has been in the game since the start of the Open Beta Test in Update 1.27.

General info

Flight Performance

Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Armaments

Suspended armament

The B5N2 can be outfitted with the following ordnance:

• 6 x 60 kg Navy Type 97 Number 6 ground bombs (360 kg total)
• 2 x 250 kg Navy Type Number 25 Model 2 bombs (500 kg total)
• 2 x 250 kg Type 98 bombs (500 kg total)
• 1 x 800 kg Navy Type Number 80 Model 1 bomb (800 kg total)
• 1 x 800 kg Navy Type 99 Number 80 AP bomb (800 kg total)
• 1 x Type 91 Mod.2 torpedo
• 1 x Type 91 Mod.3 torpedo

Defensive armament

The B5N2 is defended by:

• 1 x 7.7 mm Type 92 machine gun, dorsal gun turret (1,000 rpg)

Usage in battles

The most important advantage in arcade is the ability to reload bombs and belts midair. This translates especially well with the B5N2.

It is advised against the 800 kg bombs because the H6K can carry twice as many in exactly the same games. Instead, focus on the enemy ships or pillboxes. Make quick diving attacks, and retreat to the safety of your team's fighters to reload. Staying as low as possible can be a viable strategy, as it is difficult to safely conduct a diving attack on an enemy hugging the trees. If limited to 60 kg of bombs, focus on enemy AAA.

Using the 250 kg bombs to destroy enemy ships, or the 60 kg bombs to target AAA, is the most helpful thing you can do for the team. Try to distract any enemy that comes after you, or lead them into the guns of your allies. Every minute an enemy is focused on you is a minute your allies don't have to deal with it. Use the environment to hide your approach. Hills, mountains, and clouds are all great tools to hide from enemy fighters or shield your approach on enemy AAA. If necessary, use the tail gunner to strafe light targets. Shoot any approaching fighter. They know you will probably fail, but they also know people can get lucky.

• 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.

Pros and cons

Pros:

• Fast and manoeuvrable (powered by Nakajima Sakae 11 14 Cylinder Radial, the same engine in the A6M)
• Excellent elevator and rudder authority
• Wide variety of bombs and torpedoes + bombsight for any kind of situation
• Self sealing fuel tanks; uncommon at low br and especially rare compared to other Japanese planes.

Cons:

• Poor roll rate
• No offensive armament
• Weak defence armament
• No armour or bulletproof glass to protect the pilot or crew
• Tremendous fuel load means this plane is prone to fuel tank fires especially any hits to the wing roots (where the fuel tanks are located)

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.
