Дельта-4
The DCSS had 4 m diameter and 5 m diameter versions, with matching diameter payload fairings. Delta IV CBCs and DCSSs are integrated horizontally before being transported to the launchpad. The 4 m diameter DCSS was retired with the Delta IV Medium after the 22 August 2019 launch of a GPS-IIIA satellite on a Delta IV M+(4,2) with one CBC, two SRBs, and a 4 m diameter DCSS and payload fairing.
