In 2010, ULA stated that the Atlas V Heavy variant could be available to customers 30 months from the date of order. [12] Atlas V PH2. In late 2006, the Atlas V program gained access to the tooling and processes for 5-meter-diameter stages used on Delta IV when Boeing and Lockheed Martin space operations were merged into the United Launch Alliance.
The resulting conceptual heavy-lift vehicle was called "Atlas Phase 2" or "PH2" in the 2009 Augustine Report. An Atlas V PH2-Heavy (three 5 m stages in parallel; six RD-180s) along with Shuttle-derived, Ares V and Ares V Lite, were considered as a possible heavy lifter concept for use in future space missions in the Augustine Report.

In March 2015, an Atlas V rocket carried NASA's Magnetospheric Multiscale Mission spacecraft, [108] [109] and a Delta IV rocket orbited the GPS IIF-9 satellite on behalf of the U.S. Air Force. [110] [111] The U.S. Air Force's X-37B spaceplane was carried by an Atlas V rocket in May 2015, [112] and a Delta IV orbited the WGS-7 satellite in July ...
This is a list of launches made by the Atlas rocket family, derived from the SM-65 Atlas ICBM. The currently operational variant, Atlas V, has flown 81 consecutive missions without failure between October 2007 and January 2022. Due to the size of the list, it has been split by decade: List of Atlas launches (1957–1959)
