The Station Refuel Silo is a dockable gas station with 4 docking ports. Ships attached to it can have their main fuel tanks and thruster propellant tanks refilled, as long as the silo has any left, and the fuel pumps are open. This module is one of the heaviest modules in the game and you will have to launch it with powerful rocket parts, such as those in the Space Launch System, the N1-LOK-LK or Delta IV rockets.
Based from a user's calculations, this module contains 17 "units" of fuel. (It filled an ATV which contains 3 "units" of fuel) 5 times and filled the sixth two-thirds full)
- When the silo is in space and not attached to any other spacecraft/modules, you can self destruct it. This is useful when you want to discard empty silos from spacecraft/stations, unless the silo is too integrated into the station or modular ship.
- The silo if still on a rocket such as a tug or rocket stage can actually be interacted with to refuel them. But you have to be careful as you could also open one of the other three ports letting out all of the fuel in the rocket/tug and render it useless.
- The Station refuel Silo is the single module that carries the most fuel in the game it self.Apparently,a refuel silo an ATV ( automated transfer vehicle) docked together is all you need to get to any celestial body from HOM and back 3 or 4 times,based on the player's calculations.
