The '''Mortar''' is a ''manned'' [[Security]] building similar to a [[turret]]. It can launch [[mortar shell]]s at any target on the same map so long as it is outside of its minimum range of 30 tiles, either automatically targeted by the manning colonist, or manually targeted by the player. The effects of the mortar depend on the shell loaded.

Mortars launch [[mortar shell]]s. The manning pawn will load and fire shells at targets within a {{P|Range}}-tile firing radius, but outside of the {{P|Minimum Range}}-tile blind zone. Mortars can't fire if under any [[roof]], but the mortar shells themselves are only stopped by [[overhead mountain]]. Mortar shells can be fired over [[wall]]s. Mortars can fire 20 shots before needing to be re-armed by a {{Icon Small|reinforced barrel}} [[reinforced barrel]].

Pawns can be selected to man the mortar. They will automatically aim at enemies in range, but the player can force-target a location or pawn. Firing can be toggled with the "'''Hold Fire'''" gizmo. Note that pawns will continuously fire the mortar until ordered to leave or otherwise stop.  A mortar has a {{Ticks|{{P|Aiming Time Base #}}}} warmup time and a {{Ticks|{{P|Ranged Cooldown Base #}}}} cooldown. The cooldown does not tick down until a pawn actually mans the turret, not counting the time to grab the shell.

Mortars have a natural Forced Miss Radius of 9 tiles, i.e., the shell will land somewhere within 9 tiles of the designated tile. This is multiplied by the shooter's [[Mortar Miss Radius Multiplier]], which can be lowered by increasing [[Shooting]] skill, [[Manipulation]], and having 100% [[Sight]].

The effect on target depends on the type of [[mortar shell]] loaded into it. These shells can be manually extracted from the mortar. Mortars can be set to only accept specific types of shells at will. A summary of available shells is provided in the table below, but see the relevant shell pages for full details.

The [[AI_Storytellers#Classic mortars|Classic Mortars]] storyteller option removes the need for [[reinforced barrel]]s entirely. However, the base Miss Radius is increased to 13 tiles, and the cost of both mortars and their shells are increased. A pawn's Mortar Miss Radius Multiplier still applies when Classic Mortars is enabled.

When hit by an [[EMP]] from any source, mortars are prevented from firing and the reload countdown is paused for the duration of the stun. Mortars do not 'adapt' to EMP. If an EMP attack does more EMP damage to a mortar than its remaining HP, the mortar will explode. For most sources of EMP damage, this is below 50 HP.

If it is damaged below one third of its hitpoints, or {{#expr: {{P|Max Hit Points Base #}}/3}} HP, it has a chance{{Check Tag|What chance?}} to explode. The mortar will spark and emit a hissing sound shortly before exploding {{Ticks|240}} later. The explosion deals 50 [[Damage Type#Bomb|Bomb]] damage in a 4.9 tile radius centered around the tile covered by the mortar closest to the interaction spot - that is, the explosion is not centered on the true center of the 2x2 mortar.

Mortars are one of the best counters against [[siege]]s, which can be devastating to a colony not under overhead mountain. The siegers will start assaulting the colony once they've taken enough casualties; if you are lucky, the mortar will hit their mortar shells and cause a chain reaction. [[Sniper rifle]]s are an alternative which becomes dangerous if your opponent also comes with snipers. Sieges are also one of the best ways to get reinforced barrels, and, if allowed to build them, mortars themselves.

Mortars are one of the best counters against [[siege]]s, who will shell you with mortars themselves. Siegers will start assaulting the colony (abandoning their mortars) once they've taken enough casualties; a few mortar shots are enough to start the assault. If you're lucky, the mortar will hit their mortar shells, creating a chain reaction. Since an uninterrupted siege is devastating to a colony outside of [[overhead mountain]], mortars are usually worthwhile to build. [[Sniper rifle]]s are an alternative, though picking off the enemy becomes dangerous if they also have snipers. Conversely, sieges are also one of the best ways to get reinforced barrels, and, if allowed to build them, mortars themselves.
+
They are also useful against other stationary targets, such as [[crashed ship parts]] or [[mech cluster]]s{{RoyaltyIcon}}. For the former, mechs will start assaulting the colony if you destroy the ship part. For mech clusters, the [[Mech high-shield]]s{{RoyaltyIcon}} will block mortar shots; [[EMP shell]]s can disable the shield, but not long enough to fire a mortar again. Using 1 EMP-firing mortar, then firing other mortars after a short delay, can allow you to bypass a high shield.

Due to their long delay and overall inaccuracy, mortars aren't recommended against mobile targets, except perhaps with an [[anti-grain warhead]].

Generally, you'll want pawns with the best Shooting to operate a mortar, as they are the most accurate. [[Manipulation]] and [[Sight]] are also factors. See [[Mortar Miss Radius Multiplier]] for more details.

Mortar pits are constructions used to facilitate rapid loading and firing of mortars, store ammunition protect them and their ammunition from counter-battery fire and raiders, and/or protect the surroundings from any detonations of the same. At its simplest, a mortar pit might simply be mortar and a [[shelf]] for the shells to keep them close at hand and prevent deterioration. Additional features can be added as wanted or needed.

As mortars cannot be constructed under a mountain, they are inherently at risk from counter-battery fire from enemy [[siege]] mortars and mechanoid [[automortar]]s{{RoyaltyIcon}}. Mortars and their shells are prone to exploding themselves. Any one explosion can be stopped by a single layer of [[wall]], meaning that separating explosive items with walls is usually sufficient. But if two or more explosions occur non-simultaneously, the first explosion may destroy the wall and while the latter explosions damage items beyond it.

Unlike every other known instance, pawns that are loading mortars will '''not''' draw shells on a [[shelf]] from an adjacent tile, instead they will walk on top of the shelf to retrieve one. It is unknown if this is a bug or intended behaviour. Thus, the [[Shelf#Analysis|shelf trick]] does not cut down on walking times for mortar crew and in fact increases it, as the shelf has a path cost of {{Q|Shelf|Path Cost}}. Shelves retain their utility in keeping items stored outdoors from deteriorating.

Material choice impacts a mortar's work time, health, and beauty. Of these, beauty is increased more by a [[sculpture]] of even awful quality. Health rarely matters if a mortar is placed inside a colony; the chance of an opposing mortar shell hitting is quite low. Work time isn't an issue for colonies that are stable enough to build mortars, as the building is reusable.

As [[steel]] is the cheapest available material, it is usually the best choice to use. Steel mortars can survive 1 high-explosive impact, and the mortar can be repaired if it is actually hit. Plasteel is technically the best material, but typically isn't necessary.
