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.

The main purpose, usage and tactics recommendations

Arcade The most important advantage in arcade is the ability to reload bombs and belts midair. This translates especially well with the B5N2. I'd advise against the 800kg 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 60kg bombs, focus on enemy AAA.

Realistic and Simulator Battles Using the 250kg bombs to destroy enemy ships, or the 60kg 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.

Pros and cons of the plane


  • Fast and Maneuverable; Excellent Elevator and Rudder Authority
  • Wide Variety of Bombs and Torpedoes + Bomb Sight for any Situation


  • Poor Roll Rate
  • No Offensive Armament
  • Inadequate Defensive Armament
