Delta IV GPS IIF-01 Launch Set May 20
GPS IIF is the first of a new generation of GPS satellites going into orbit. A dozen such Boeing-built satellites will be launched over the next several years to replace 20-year-old satellites now in service.
This will be the first GPS mission to launch on a Delta 4, after 49 missions launched atop the smaller Delta 2 between 1989 and 2009. Future GPS spacecraft will be lifted into orbit on the Delta 4, on the Atlas 4 and on ULA’s Evolved Expendable Launch Vehicle.
