A baffle plate or isolation plate was a component of warp cores, damage to which could be potentially catastrophic. In 2266, Charlie Evans used his psycokinetic powers to remove a warped baffle plate on the survey vessel Antares, whose captain was attempting to warn the USS Enterprise of the danger that Charlie posed. Removing the baffle plate caused a warp core breach, destroying the ship with all hands lost. (TOS: "Charlie X" ) The baffle plate was among the items removed from the SS Santa Maria after it had crash landed on Orellius Minor in 2360. (DS9: "Paradise")
