The contractor was standardizing payload interfaces, launch pads, and infrastructure so that all configurations of each contractor's EELV family can be launched from the same pad and payloads can be interchanged between vehicles in the same class (i.e., medium, intermediate, or heavy). As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX.

The USAF and United States Space Force (USSF) plan to use the next generation NSSL launch vehicles until at least 2030.[31]. [12] Boeing was awarded a contract for 19 out of the 28 launches; Lockheed Martin was awarded a contract for the other 9. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. 1320 The goal was the creation of a cost-efficient and reliable family (or families) of "right size" spacelifters based on standardized fairings, liquid core vehicles, upper stages, and solid rockets. That includes five engines that ULA currently has in its possession, which are not limited by the sanctions, since they were fully paid for prior to the Russian invasion of Crimea.
