摘要

The United Launch Alliance's (ULA) plan to field a new rocket engine with startup Blue Origin called the BE-4 is only one step of a larger strategic plan to take the company from a sole-source monopoly mentality to competing in a burgeoning commercial market. With that plan, ULA's current launchers-the Atlas Ⅴ (developed originally by Lockheed Martin) and Delta Ⅳ (originally developed by Boeing)-will likely be supplanted by a new, yet-to-be-named rocket design within the next decade. The Atlas Ⅴ and Delta Ⅳ are the workhorse rockets for the Defense Department, and have been since the early 2000s. But both now have a limited future. Last year, former ULA Chief Executive Officer Mike Gass said the per-unit cost of an Atlas Ⅴ 401 mission was $164 million; a Delta Ⅳ heavy mission was priced at $350 million. These prices are averages for the 36-core deal signed between ULA and the U.S. Air Force.
