The '''high-explosive shell''' is the most common kind of [[mortar shell]], that deals 50 damage in a 3-tile radius upon exploding.

== Acquisition ==
High-explosive shells can be crafted at a [[{{P|Production Facility 1}}]] once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. They require {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}. The steel cost is increased to 25 if the [[AI Storytellers#Classic mortars|Classic Mortars]] difficulty option is enabled.

They can also be purchased from [[traders]].

Finally, [[siege]] raids will have high-explosive shells drop podded to them, and if unused by the raid, can be taken by the player.

== Usage ==
{{Ingredient List|noCollapse=true}}

== Summary ==
When fired from a mortar, {{lc:{{P|Name}}}}s deal {{P|Damage Base}} [[Damage types#{{P|Damage Type}}|{{P|Damage Type}}]] damage in a {{P|Blast Radius}} tile radius.

When damaged beyond 70% of its health, it will explode after between {{ticks|30}} and {{ticks|60}}, dealing 50 [[Damage Type#Bomb|Bomb]] damage in a radius around itself. The radius depends on the quantity in the stack, with a single shell covering a 2.9 tile radius, and expanding this radius proportional to the square root of the stack size times 0.4 up to a maximum radius of {{#expr: 2.9+((24*0.4)^0.5) round 2}} tiles at a full stack of 25.

They are also used in the construction of explosive [[IED trap]]s.

== Analysis ==
High-explosive is the standard shell for mortars, dealing high damage to any target with a decent blast radius. Mortars in general are quite resource-intensive, so it's best to wait until mid-game until beginning the use of mortars. Given the mortar's inaccuracy, it's best to have a battery of mortars firing at once to deal heavy damage to the enemy.

Mortars are most useful against stationary targets, such as [[siege]]s, [[crashed ship parts]], and [[mech cluster]]s{{RoyaltyIcon}}. Against sieges in particular, dealing enough damage will force the raiders to assault directly - as opposed to them peppering ''your'' base with mortar shells. A siege's mortars can and will deal large infrastructural damage to any base not under [[overhead mountain]]; your mortars are powerful defenses against them.

=== Storage ===
As with all explosive items, these should be stored in separate storage containers. For maximum protection, put each stack of shells in a separate 1x1 stone box to prevent chain reactions. Pawns currently in a tantrum should be stopped at all costs, whether it be by arresting, creating another stockpile zone with a higher priority than the shell zone and prioritizing hauling the shells, or simply by shooting the pawn.

== Version history ==
* [[Version/0.18.1722|0.18.1722]] - Added to replace mortar type system.
