Sky Blu Airstrip is a remote air facility located on the Ronne Ice Shelf in Antarctica, operated by the British Antarctic Survey (BAS). Situated at approximately 74°S, it serves as a logistical hub for BAS operations in the region, supporting scientific expeditions and supply missions across the continent. The airstrip is constructed on blue ice, a naturally compacted and wind-polished surface that provides a hard runway without the need for conventional paving. This blue-ice runway allows wheeled aircraft, including the BAS Dash-7 and later intercontinental aircraft, to land directly, making it a critical link in Antarctic aviation infrastructure. Sky Blu does not serve commercial passenger traffic and has no permanent terminal facilities. It functions primarily as a staging and refueling point, enabling deeper access to Antarctic research stations and remote field camps during the austral summer season.
