Description

The BK90 is a German modification of the American 90 mm gun M1/M2/M3 taken from old M47s. It has access to HEATFS, HE, and HESH which is the only new round.

Vehicles equipped with this weapon

General info

The gun's HEATFS shell has amazing penetration at long range for the BR combined with a short reload time. The gun its great for ambushing and sniping, however lacking kinetic energy projectiles makes even trees an obstacle.

Comparison with analogues

  • M36 (90 mm) - American variant of the cannon, which the BK90 was derived from. Though it does not have the BK90's HESH round, it has a large variety of AP rounds for use.

Usage in battles

The BK90 with HEATFS is a formidable opponent on the battlefield that can penetrate every 6.7 tank's frontal armour at any range. It is best used in hit-n-run types of attack due to the vehicles it is mounted on.

Pros and cons

Pros:

  • Access to HEATFS that can penetrate every tank that it typically has to face

Cons:

  • No kinetic ammunition
  • Of the chemical rounds available, only the HEATFS round is of noteworthy use

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

  • The BK90 cannon on a Hanomag-Henschel JPz 4-5

  • Ru 251 with BK90
