Pros and cons


  • The mortar fires on an high angle, which means it can reach hidden targets behind obstacles that block your guns
  • Increased range compared to conventional depth charges.
  • Can also obliterate enemy ships if it lands on the decks, dealing heavy damage.


  • Due to the high angle of fire, it has a curved trajectory and thus it takes a short while to hit the water.
  • The mortar is fixed in position, which means it cannot traverse horizontally or vertically.
  • The mortar is inaccurate: spigot projectiles spread out on a large area. Several projectiles are needed to secure a hit.


Examine the history of the creation and combat usage of the weapon in more detail than in the introduction.
