We encourage you to use one of these browsers for the best experience. While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space.

If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry. The Atlas V family is capable of carrying payloads of 8,900 kg (19,620 lbs) to geosynchronous transfer orbit, and can lift 16,034 kg (35,343 lbs) to low-Earth orbit. Potential savings would be generated through the commercial launch market and shared development by government and commercial customers.
