Jubany Airbase, identified by ICAO code SAYJ, is a military and scientific airstrip located at Carlini Base (formerly Jubany Base) on King George Island, South Shetland Islands, Antarctica. It serves Argentina's permanent Antarctic research station, operated by the Argentine Antarctic Institute (IAA) under the Argentine Army. The airstrip primarily supports logistical operations, supplying personnel and materials to the research station throughout the year. It handles light aircraft and helicopters rather than commercial jet traffic, and its operations are governed by the needs of scientific and governmental missions in the region. The base is notable for its cooperation with other national Antarctic programs, including Germany's Alfred Wegener Institute, which has maintained a joint presence at Carlini Base for decades.
