An Atlas 5 launches the fourth Block IIF Global Positioning System satellite, GPS 2F-4 (IIF-4). It was the first GPS launch on an Atlas in 28 years and the first time ever an Atlas rocket launched a GPS satellite for the modern, operational Block 2 constellation which began in 1989 on the inaugural Delta 2, which was the vehicle of choice until the IIF series began in 2010.
