Antiproton Containment Rods are small rods that serve the purpose of storing and buffering Antiprotons immediately before they are bled into the MagnetoplasmaDynamic Drive, which is the main source of propulsion and power for large spaceships such as the Andromeda Ascendant, Righteous Fist of Heaven Class vessels, and many others. When they contain the Antiprotons, they are extremely dangerous and volatile, and must be treated very, very carefully. They are an important part of the Andromeda's Slipstream drive, as they allow the Gravity Field Generator to be activated and rip a hole in the fabric of the universe, which ships then use their Slipstream Runners to stabilize for FTL travel.
