ULA successfully launches their Delta Medium rocket for the last time

This morning at 9:06am EDT, United Launch Alliance launched their Delta IV rocket in the medium configuration, with a 4-meter fairing and 2 solid rocket motors. It was carrying the GPS III satellite which is a more advanced and highly accurate GPS system for civil users.

The Delta IV launched from Space Launch Complex 37 in Cape Canaveral, FL, completing 17 years of successful launches for ULA. The only rockets left in the Delta family now are the large Delta Heavy rockets, which will only launch 5 more times before Delta is phased out completely.

After Delta and Atlas have been retired, ULA will be relying on their new Vulcan rocket, which has more power and capability than both Delta and Atlas rockets.
