The B6N2a Model 12Ko is a rank II Japanese bomber with a battle rating of 2.0 (AB) and 2.3 (RB/SB). It was introduced in Update "Starfighters".

It is the sucsessor to the B5N, and if you liked the B5N2, you will LOVE the B6N! Simply put, the B6N is a faster, more well defended B5N, and it will prove useful in a combat situation.

General info

Flight performance

The B6N2a Model 12 Ko "Tenzan" is a high performance torpedo bomber, capable of not only ground attack but naval attack, and can successfully outmanoeuvre anything it wishes (excluding biplanes). It has a powerful 1,600 hp engine and a supercharger for high altitude base bombing, and it is a highly capable aircraft.

Survivability and armour

The B6N2a Tenzan fires its lower turret at an approaching enemy fighter

The B6N2 has no armour protection, and no self-sealing fuel tanks, so it is very susceptible to critical damage and fires.


Suspended armament

The B6N2a Model 12Ko can be outfitted with the following ordnance:

  • 6 x 60 kg Navy Type 97 Number 6 bombs (360 kg total)
  • 2 x 250 kg Navy Type Number 25 Model 2 bombs (500 kg total)
  • 1 x 800 kg Navy Type Number 80 Model 1 bomb (800 kg total)
  • 1 x 835 kg Type 91 Model 2 torpedo
  • 1 x 850 kg Type 91 Model 3 torpedo

The 800 kg bomb will destroy 1 base, it's a good pick for maps with few ground targets! The 250 kg bombs are great for destroying pillboxes and tanks, but you can only have two of them. Make sure to use a slight dive when bombing and use the bombsight for increased accuracy! The 6 x 60 kg bombs are a great option for this plane. Since they weigh so little, you can be super accurate with these bombs, just aim the crosshair where you want the bomb to drop, and pull up. No need for a bomb sight!!! Use these bombs for light targets such as AAA, Vehicles, Armoured Cars, Artillery, Howitzers, Machine Guns, and Bridges. The torpedoes are not really useful for this plane in air battles, as ships only spawn in pacific maps, and this plane is at too low of a BR to be put in a Pacific Theater battle.

Defensive armament

The B6N2a Model 12Ko is defended by:

  • 1 x 13 mm Type 2 machine gun, turret (750 rpg)
  • 1 x 7.92 mm Type 1 machine gun, turret (300 rpg)
A Peashooter tries to tackle the B6N2a Ko

For the 13 mm machine gun, select "Default" belt because it has the most incendiary potential. It's a great turret for its BR. The 7.92 mm gun is a great gun, use the AP-T belt, as it has the most tracers and the most incendiary potential.

Usage in battles

This plane is great for bombing medium tanks, light pillboxes, howitzers, and vehicles. Since it is so fast, it can make multiple trips to the airfield if a resupply of bombs is needed. There is also a chance that you will be placed in a pacific map, where the torpedo may actually come in handy. The torpedo is a good pick for destroyers and light cruisers. If you choose to squad up with friends, you can tackle battleships and carriers with multiple torpedoes.

Pros and cons


  • Regular Japanese navy torpedo bomber armaments
  • Decent manoeuvrability for a bomber
  • High top speed for a torpedo bomber
  • 13 mm Type 2 machine gun in the rear can tear apart chasers
  • 7.92 mm underneath has more firepower than the standard Type 92 machine gun used on the two previous models
  • Torpedo has the highest drop speed in the game at 350 mph (580 km/h) and is one of the most feared torpedoes in Naval Battles
  • 1550 hp engine


  • No frontal offensive armament
  • Dead zones directly behind the aircraft, you are better off turn fighting and using your turrets while they struggle to complete the turn
