The '''Mortar''' is a ''manned'' stationary siege defense mechanism. It launches [[mortar shell]]s one at a time at any enemy that enters its 500-tile firing radius, or at a target set by the player. Once an enemy has entered within 30 tiles of the mortar, it will cease firing. The range indicator of mortars is not its actual range, but the size of its blind spot. It cannot fire if covered by a roof. It has a 4-second warmup time, a 28-second cooldown, and a 10-tile forced miss radius. (The forced miss radius is 13 if the [[AI_Storytellers#Player_tools|Classic mortars]] storyteller option is enabled.) Mortars explode in a 4.9-tile radius when destroyed, dealing 50 damage. 

Loading different shells into it will produce different effects. These shells can be manually extracted from the mortar. Mortars can be set to accept different types of shells. Make sure the shells you need are in an "allowed" zone for your mortar operators; a set of shelves works well to store mortar shells.

== Acquisition ==
To construct a mortar, the [[Research#Mortars|Mortars]] research must be complete and a construction skill of 5 is required. Each mortar requires {{icon|steel|150}} [[steel]], {{icon|component|6}} [[component]]s and {{icon|buildingmat|75}} of any [[metal]]. As of 1.3 mortars require one [[reinforced barrel]] to craft if classic mortars is not enabled.

Alternatively, they can be claimed and taken from [[Raids#Siege|Sieges]].

The mortar shells required to use the mortar must also be acquired. See their respective pages for details.

==Summary==
Mortars require a pawn to load and fire shells. Their [[skills]] have no effect on accuracy, however, pawns incapable of violence will refuse to man them. Unlike drafted colonists, mortar personnel do not return to their normal schedule when undrafted and must be manually relieved from the mortar job. Mortars have a forced miss radius of 10 tiles i.e. the shell will land somewhere within 10 tiles of the designated tile. This is increased to 13 if the [[AI_Storytellers#Player_tools|Classic mortars]] storyteller option is enabled. There is no other way to increase mortar accuracy. 

Firing a shell has a 4 second warmup, and a 28 second cooldown. Note that the cooldown does not tick down while no pawn is manning the turret, even if they are in the process of retrieving another shell. 

Every 20 shots, a [[reinforced barrel]] is required. This requirement does not exist, and reinforced barrels are removed from the game entirely, if the [[AI_Storytellers#Player_tools|Classic mortars]] storyteller option is enabled.

If it is damaged below one third of its hitpoints, or {{#expr: {{P|Max Hit Points Base #}}/3}} HP, it has a chance<sup>[What chance?]</sup> 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.

==Analysis==
Mortars are too inaccurate to target moving enemies, except when targetting large, dense groups or when using antigrain shells. Instead, they're better suited against sieging enemies, preparing raiders, and [[Mechanoid_cluster|mech clusters]] {{RoyaltyIcon}}. Note that [[Mech high-shield]]s {{RoyaltyIcon}} will block mortar shots and, if present, can render mortars ineffective against clusters, however the use of [[EMP shell]]s will temporarily disable the shield. The shield will not be down long enough for a the EMP-firing mortar to load a shell and fire again, but a single EMP-firing mortar and several HE-firing mortars can work in tandem to attack the shielded clusters during the vulnerability by firing the EMP slightly in advance of the HE rounds.

Enemy [[Events#Sieges|sieges]] typically spawn with 2 mortars, that will be constructed by the enemy, and then fired at your base. Shells fired from mortars will break through constructed roofing but not through mountains (or any tile underneath one). Following a siege, it is possible to loot mortars from siege attacks, so long as the enemy builders complete construction, by reinstalling them in your base. Pawns assigned to construction will haul them to their new location.

When they explode, they sizzle for {{ticks|240}} and explode with a radius of 4.9 cells. 

When hit by an [[EMP]] from any source, they 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.

== Version history ==
* [[Version/0.5.492|0.5.492]] - Added as the Incendiary Mortar and Explosive Mortar
* [[Version/0.6.532|0.6.532]] - EMP mortar added.
* [[Version/0.9.722|0.9.722]] - Now requires shells to fire.
* Beta 18 - the three types of mortars ([[Incendiary shell|Incendiary]], [[EMP shell|EMP]] and [[High-explosive shell|explosive]]) were replaced with a single type, which fires different types of shells that achieve the same effect. In addition, two new shells are added, the [[firefoam shell]] and the [[antigrain warhead]].
* [[Version/1.1.2618|1.1.2618]] - the cost was increased from 100 steel, 50 materials and 4 components.
* [[Version/1.3.3066|1.3.3066]] - Mortars now require uncraftable [[reinforced barrel]]s to build and rearm after every 20 shots. Forced miss radius lowered from 13 to 10. All craftable [[mortar shell]]s have had their crafting recipes lowered by 10 [[steel]]. All 1.3 changes are reversible in the "Classic Mortars" storyteller option. 
* [[Version/1.3.3067|1.3.3067]] - Mortars don't drop their barrels when deconstruct if under 50% "fuel" i.e. after 10 shots have been fired with that barrel.
