Pegasus Field (ICAO: NZPG) is an airstrip in Antarctica, the southernmost of three airfields serving McMurdo Station. Pegasus is a blue ice runway capable of handling wheeled aircraft year-round. The other two are the snow runways at Williams Field (ICAO: NZWD) that are limited to ski-equipped aircraft, and the Ice Runway (ICAO: NZIR) on the sea-ice available during the summer Antarctic field season.
