Description:

• A United Launch Alliance Delta 4 rocket will deploy the Air Force's fifth Block 2F navigation satellite for the Global Positioning System. The rocket will fly in the Medium+ (4,2) configuration with two solid rocket boosters.
• The GPS-2F satellites do not need to carry an apogee kick motor, in contrast to the earlier generations, as the launch vehicles provide direct insertion into the GPS orbit. Originally the Delta-4M version was to be used for the Delta launches, but a mass growth of the satellites required a switch to the more powerful Delta-4M+(4,2) version.
• USA 248, known also as GPS 2F-5 will become a primary broadcasting satellite in the constellation when it becomes operational by May 2014.

Mission details:

• Launch delayed from Oct. 17, 2013.
• United Launch Alliance flew a Boeing Delta 4 from Cape Canaveral on Feb 21, 2014 carrying a Block IIF Global Positioning System satellite to 20000 km circular orbit. The payload is GPS Space Vehicle Number 64, the 5th in the IIF series to be launched.
