The Longsword Interceptor was first seen in the episode Evacuation Plan. This quick maneuvering aircraft was seen chasing Pelican Four Seven Niner. Before the two Longswords were able to shoot down the Pelican, they were destroyed by the Mother of Invention. In Season 10, several Longswords were involved in a dogfight against the Freelancer frigate in the UNSC Scrap Metal Recycling Station.
