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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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 />.
