A Delta IV rocket carrying the WGS-9 SATCOM US Military satellite was launched successfully from Space Launch Complex-37 at Cape Canaveral Air Force Station. The Delta IV WGS-9 SATCOM satellite will provide the US Military with enhanced capability to contact troops in the field.
This mission was launched aboard a Delta IV Medium+ (5, 4) configuration. This has a 5m diameter payload fairing for larger payloads, and 4 Graphite-Epoxy Motors (GEM-60s) strap-on boosters to provide the required thrust.
This was ULA’s 3rd launch of 2017 and the 118th successful launch since the company was formed in December 2006.
