An antimatter pod

Antimatter storage pods, also known as antimatter pods, containment pods or matter/antimatter pods, were magnetized self-contained storage units which contained un-reacted antimatter fuel for a starship. Antimatter pods used an antimatter containment field to isolate the fuel within from contact with normal matter, thereby prohibiting catastrophic reaction. (TOS: "Obsession", TNG: "Disaster", ENT: "Canamar", DIS: "Battle at the Binary Stars")

It was vital that antimatter pods be self-contained, so that their containment fields would continue to function even after being ejected from the starship. (VOY: "Resolutions") Starfleet Regulation 3287.0 compelled their use aboard Starfleet vessels. (TNG: "Night Terrors")

Aboard the Galaxy-class USS Enterprise-D, in the Engineering Systems Database, there was a folder titled Antimatter Containment Pod Maintenance. This folder contained technical manuals relevant to the topic. (TNG: "Booby Trap", okudagram)

In ultimately unused dialogue from the final draft script of TOS: "The Naked Time", Montgomery Scott reported to Captain Kirk that the USS Enterprise's "anti-matter tanks" were "primed."


In 2267, the antimatter pods of the USS Enterprise were slightly damaged by a surprise Klingon attack. At the time of the attack, the Federation starship was en route to Organia. (TOS: "Errand of Mercy")

Later that year, as the Enterprise orbited Gamma Trianguli VI, the potency of the antimatter pods decreased. Eventually, the pods became inert. It was determined by the starship's crew that a tractor beam transmitted by Vaal resulted in the pods condition. With the destruction of Vaal, and the beam's termination, the pods potency returned. (TOS: "The Apple")

In 2365 the USS Yamato's antimatter containment field in their antimatter pods failed, causing the destruction of the ship. (TNG: "Contagion")

In 2366 the non-corporeal Koinonians drained antimatter from the containment pods to use it as energy to create their replica of Marla Aster. This was stopped by increasing the shield harmonics to match the antimatter containment effectively severing the Koinonian beam. (TNG: "The Bonding")

Later that year, radiation that had leaked from Doctor Nel Apgar's station in orbit of Tanuga IV threatened the USS Enterprise-D's antimatter pod. If the radiation had surged in or near them, it would have destroyed the ship. (TNG: "A Matter of Perspective")

In 2369, Commander Benjamin Sisko ejected the antimatter pod of the USS Yangtzee Kiang just before the runabout crashed on a moon in the Gamma Quadrant. (DS9: "Battle Lines")

Later that year, while traveling back to the Enterprise by runabout, the starboard antimatter pod has been completely drained, despite the fact that there was no leak and all of the other engine systems were fully operational. It turned out that the runabout had entered a region of temporal fragments that made the antimatter pod work longer than the rest of the shuttle had. (TNG: "Timescape")

In 2372, while Captain Janeway and Commander Chakotay were trapped on a planet, Lieutenant Tuvok had to fight off several Vidiian warships. To do so, he released an antimatter pod and let it get close to the ships, and then fired a photon torpedo at it, causing an explosion which severely damaged the enemy ships. (VOY: "Resolutions")
