The Antarctic Service Expedition was the first government-funded expedition of Admiral Richard E. Byrd (his first two expeditions in 1928–1930 and 1933–1935 were privately funded). East Base was built using Army knockdown buildings and a crew of 23 led by Richard Black, after Admiral Byrd had to return to Washington on the USS Bear. The war time pressures and pack-ice in the bay which prevented ship movement led to the evacuation of the base in 1941 by air.
