The expedition observed more than 1.5 million square miles of Antarctica, half of it previously unexplored, and took 15,000 aerial photographs.
The following season the U.S. Navy Second Antarctic Developments Project (Operation Windmill) used ship-based helicopters to get geodetic ground control for the aerial photographs. The expedition contributed to production of the first medium-scale maps of the region and influenced decisions regarding locations of stations for the International Geophysical Year (IGY) that occurred 12 years later.
At a time when other nations had embarked on programs of permanent bases, the U.S. Navy Second Antarctic Developments Project also was a vehicle for continuing the U.S. presence in Antarctica.
