Solid fuel is a resource contained in and used by solid rocket boosters. Unlike other resources, it cannot be replenished, transferred between parts, or routed throughout a vessel. Solid fuel is only ever found inside solid rocket parts, and it can only be used by activating the part and allowing it to consume its entire supply.
Solid fuel is heavier than an equivalent quantity of liquid fuel (but lighter than liquid fuel and oxidizer together), and is mostly used to provide quick acceleration to a vessel immediately after launch.
