As the Atlas V core is designed around RP-1 fuel and cannot be retrofitted to use a methane-fueled engine, a new first stage is being developed. This booster will have the same first-stage tankage diameter as the Delta IV and will be powered by two 2,400 kN (540,000 lb f ) thrust BE-4 engines.

The AJ-60A rocket motor was developed between 1999 and 2003 for use on the Atlas V. [2] On January 19, 2006 the New Horizons spacecraft to Pluto was launched directly into a solar-escape trajectory at 16.26 kilometers per second (58,536 km/h; 36,373 mph) from Cape Canaveral using an Atlas V version with 5 of these SRBs and Star 48B third stage.

Atlas was a liquid propellant rocket burning RP-1 kerosene fuel with liquid oxygen in three engines configured in an unusual "stage-and-a-half" or "parallel staging" design: two outboard booster engines were jettisoned along with supporting structures during ascent, while the center sustainer engine, propellant tanks and other structural ...
The Atlas V can fly in multiple configurations, but only one affects the way Centaur integrates with the booster and fairing: the 5.4 m (18 ft) diameter Atlas V payload fairing attaches to the booster and encapsulates the upper stage and payload, routing fairing-induced aerodynamic loads into the booster. If the 4 m (13 ft) diameter payload ...
The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished; i.e., the Atlas V series is only counted once for all its configurations 401–431, 501–551, 552, and N22.

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)
