The upcoming ULA Vulcan launch could be a National Security mission, specifically USSF-87 or GPS III SV09.
The GPS III SV09 satellite is scheduled to be launched aboard a Vulcan VC2S rocket before the end of the year.
The GPS III SV09 satellite has been shipped to Florida for launch.
The GPS III SV09 satellite will be ULA's next launch after ViaSat-3 F2, ahead of USSF-87.
GPS III SV09 is designed to strengthen the GPS navigation network.
GPS III SV09 traveled from Denver to Florida.
