Small Solid Oxidizer Tank

The Small Solid Oxidizer Tank is a rocket supply building used to provide solid oxidizer for spaceflight. Solid oxidizers allow rocket fuel to be efficiently burned in the vacuum of space, making them a required part of solid-fueled rocket setups.

Because oxidizer is consumed to support combustion, a rocket cannot use solid fuel effectively without an oxidizer source. The Small Solid Oxidizer Tank fills that role in a compact form, making it useful when space on a rocket is limited or when only a smaller oxidizer reserve is needed.
