Jump to: navigation, search


The 81 mm Mk 2 mortar is a special armament seen on American naval craft. As a mortar, the projectiles are fired at a high parabolic trajectory and at a slow speed. While making it a difficult weapon to use against fast-moving boats, a direct hit can cause devastating damage to them.

General info

The 81 mm Mk 2 special armament is a supporting weapon on the naval craft it is mounted on, never to be considered a naval craft's main armament. Though small in size, the projectiles it fires are of high-explosive nature and so the appropriate targets should be selected when engaging with the weapon.

Available shells

The Mk 2 mortar does not give any ammunition options that users can choose to fire. However, the Mk 2 mortar fires a high-explosive projectile that can cause good damage should it hit its desired target.

Comparison with analogues

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against the main opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons


  • High explosive payload can cause large amounts of damage if they hit lightly-armoured craft, and can still cause damages at a near-miss
  • High parabolic firing angle can allow the naval craft mounts to fire at targets across island land masses without direct line-of-sights


  • Projectiles fired are very slow, and so leading shots can be difficult


Examine the history of the creation and combat usage of this weapon. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.


An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
