"Final Flight: Delta IV Heavy Retires After 64 Years of Space Missions"
The Delta IV Heavy rocket made its final flight, successfully launching a top-secret payload for the National Reconnaissance Office before retiring after 16 missions. United Launch Alliance is now focusing on its new Vulcan rocket, while the future of the launch site, SLC-37B, remains uncertain.
