FSX Naval Air Station Argentia Scenery. Presented here is NAS Argentia, a former base of the United States Navy that operated from 1941-1994. It was established in the community of Argentia in what was then the Dominion of Newfoundland. This scenery package was designed and built as best as could be portrayed of the air station as it last appeared before being closed down by BRAC in 1994. Included is both the airfield as well as associated scenery. By Marshall Carter.
