P5S-381 is the Tau'ri designation for a planet in the Milky Way galaxy with a very strong ozone layer, which was why the planet was chosen to become the new homeworld of a large group of Enkarans, who need a thick ozone layer to prevent blindness due to an increased sensitivity to UV light.
SG-1 negotiated between the Gadmeer and the Enkarans, and in the end the vessel was used to transport the Enkarans to their original homeworld (which doesn't have a Stargate). Afterwards, the planet continued to be terraformed. (SG1: "Scorched Earth")
