The 28th Soviet Antarctic Expedition was an expedition to Antarctica undertaken by the Soviet Union and the German Democratic Republic.
Although the GDR could not build a research station as a result of not having signed the Antarctic Treaty, it operated a research station near the Soviet Novolazarevskaya station.
In 1983, six Germans joined the 28th Soviet Antarctic Expedition' to research meteorology, physics of the upper atmosphere, geology and geophysics.
