'''Mortar''' is a type of smoothbore cannon using exclusively high-angle plunging fire. It is able to use indirect fire, with projectiles, called bombs, dropping onto targets from above. Mortars are typically smaller, lighter weapon systems with a shorter range than the other cannons.

Compared to howitzers they have a shorter range, lack the ability to fire at a shallow angle, typically are lighter, and finally have a smoothbore rather than rifled barrels. Compared to cannons, they are solely an indirect fire weapons, lack the ability to shoot at a shallow angle, lack range, and have a much longer time to target, making them less suitable to deal with mobile targets.

Unlike rockets, mortars lack an internal propulsion system, they use a propellant charge instead, which deflagrates creating high-pressure gasses which pushes the bomb out of the mortar. But there is a one notable exception to this rule - Rocket Mortars. Particularly common during the World War Two, they used rockets as ammunition, could be fired at shallower angles, and in some cases they had a rifled barrel, breaking with all the typical conventions of the mortars.

== General Info ==
Naval mortars were introduced into the game with the initial release of the naval forces, patch [[Update 1.83 "Masters of the Sea"]], which introduced a few types of mortars, such as [[Y-gun Mk.VII depth charge]] or mortar-launched [[WBG depth charge]]s.

Mortars mounted on a ground vehicles were first introduced with [[Matilda Hedgehog]] in [[Update "New Power"]].

== Usage of mortars in-game ==
Mortars enjoy a significant advantage of being able to put a very large explosive on the target, even if it's out of line of sight. The high arc of fire, however, brings several significant disadvantages, making mortars extremely situational, requiring a target in a right spot, significant lead against moving targets, and some luck, as mortars have spread and are easy to avoid by manoeuvring.

Mortars have only a single ammunition type available, and it's typically either an impact high-explosive or a depth charge.

In naval battles, mortars are not affected by the "Highlight projectile fall point", "Highlight targeting point" or "Play buzzer sound when projectile hits the water" settings. There are no interface elements assisting in aiming.

In ground battles, the exact behaviour of the mortar in question depends on the platform. [[Matilda Hedgehog]] has a text indicating range at which rockets will land - "Hedgehog Rockets - 220m", but no other assists. On the other hand, [[Churchill AVRE Petard]] can have its impact points controlled with a use of "Sight distance control" hotkeys.

== Decorations ==
In addition to the weapons, a number of mortar decorations were awarded. These have no active use in game, they are purely cosmetic items which can be placed on the vehicles.
