Capitalsm in space: ULA yesterday used its Delta 4 rocket to successfully place in orbit an Air Force communications satellite.
This is one of the last launches of the the Delta 4 member in the Delta rocket family.
The mission marked the next-to-last flight of the Delta 4 rocket variant with a single first stage core — known as the Delta 4-Medium — as ULA begins retiring segments of its launcher family in preparation for the debut of the new Vulcan booster, which the company says will be less expensive than the existing Atlas and Delta fleet.
Gary Wentz, ULA’s vice president of government and commercial programs, said the company’s decision in 2014 to retire the Delta 4-Medium was intended to reduce the company’s costs. “We started looking at the products that we were providing, and found that maintaining these two families of launch vehicles, both the Delta and the Atlas, through this period decreased our flight rate, and therefore increased our costs,” Wentz said. “That really drove it, based on the competitive industry we’re in, trying to maximize our competitiveness.”
The Delta 4-Medium family provides the same range of lift capability as the less expensive Atlas 5 rocket. The Delta 4-Heavy, which will remain operational through at least the early-to-mid-2020s, uses three Delta 4 first stage cores bolted together to haul heavier payloads to orbit than any of the Atlas 5 configurations.

In the national rankings, the U.S. has now widened its lead on China to 5 to 3.
Note that two different American companies are matching the launch numbers of three other whole countries. This I think illustrates well the power of freedom and competition. Rather than have a single nationalized rocket system (as was attempted in the 2000s when Boeing and Lockheed Martin created ULA, then the only American rocket company), the U.S. has transitioned back to its roots, allowing freedom to produce multiple companies competing for both private and government business. This has reduced costs, encouraged innovation, and ended up producing more jobs and wealth.
