The firefoam shell is a type of mortar shell that upon exploding, spreads firefoam in a 5-tile radius, extinguishing all fires and preventing new ones.
Acquisition[edit]
Firefoam shells can be crafted at a Machining table once the Firefoam research project has been completed. They require 25 Steel, 800 ticks (13.33 secs) of work, and a Crafting skill of 4. The steel cost is increased to 35 if the Classic Mortars difficulty option is enabled.
It can also be purchased from traders.

Summary[edit]
When fired from a mortar, firefoam shells spreads firefoam in a 5 tile radius, extinguishing all fires and preventing new ones.
When damaged beyond 70% of its health, it will explode after between 30 ticks (0.5 secs) and 60 ticks (1 sec), spread firefoam in a radius around itself. The radius depends on the quantity in the stack, with a single shell covering a 9.9 tile radius, and expanding this radius proportional to the square root of the stack size times 0.4 up to a maximum radius of 13 tiles at a full stack of 25.
They are also used in the construction of IED firefoam traps.
Analysis[edit]
Actually firing a firefoam shell from a mortar is very niche. The tiny, 5-tile radius isn't enough to cover large-scale fires, but mortars lack the precision to drop on small fires accurately. Due to the mortar's blind spot, it cannot extinguish fires inside your colony. For fires outside of your colony, the game will automatically start rain whenever fires get too big - unless a weather controller
is forcing fog. Generally, foam turrets or firefoam pop packs are better as mobile fire extinguishers. Even Pyromaniacs can operate either.
Firefoam shells are most useful to create IED firefoam traps. IEDs must be directly lit on fire or triggered by a colonist, but are cheaper to create than a firefoam popper, while having a much larger radius than the firefoam pop pack. In theory, destroying a firefoam shell creates the same firefoam as the IED trap for half the cost. However, the shell must be damaged to set off; while guns cannot damage the shell, gunshots can trigger an IED.
