Propellant tank
A propellant tank is a container which is part of a vehicle, where propellant is stored prior to use. Propellant tanks vary in construction, and may be a fuel tank in the case of many aircraft.
In rocket vehicles, propellant tanks are fairly sophisticated since weight is on a premium.
