The high-explosive shell is the most common kind of mortar shell, that deals 50 damage in a 3-tile radius upon exploding.
High-explosive shells are made using 15 steel and 15 chemfuel at a machining table and requires Mortars to be researched. Requires a Crafting skill of at least 4. The steel cost is increased to 25 if the 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.
When fired from a mortar, high-explosive shells deal 50 Bomb damage in a 2.9 tile radius.
When damaged beyond 70% of its health, it will explode after between 30 ticks (0.5 secs) and 60 ticks (1 sec), dealing 50 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 6 tiles at a full stack of 25.
They are also used in the construction of explosive IED traps.
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 sieges, crashed ship parts, and mech clusters. Against sieges in particular, dealing enough damage will force the raiders to assault directly - as opposed to peppering your base with mortar shells. A siege's mortars can and will deal large infrastructural damage to any base not under overhead mountain, so mortars are powerful defenses against them.
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.
