ULA's Vulcan is replacing the company's workhorse Atlas 5 rocket and the already-retired Delta 4 family of launchers.

Depending on weather and cloud cover, ULA Vulcan rocket launch in Cape Canaveral may be seen from Vero Beach to Port St. Lucie to Fort Pierce, Florida

United Launch Alliance completed its first US national security mission with the newly developed Vulcan rocket, a key test of the vehicle’s ability to put satellites into high orbits above the Earth.
