A third stage was added to increase the heliocentric (escape) speed. This was the first launch of the Atlas V 551 configuration with five solid rocket boosters, and the first Atlas V with a third stage. [184] On 6 December 2015, Atlas V lifted its heaviest payload to date into orbit – a 16,517 lb (7,492 kg) Cygnus resupply craft. [185]
Falcon 9 Block 5, the most prolific active orbital launch system in the world. This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list ...

Revision of Atlas V 400, with optional solid strap-on boosters, and Centaur stage encapsulated inside 5.4 m payload fairing. Atlas V N22: 2019-2: 1: 1xRD-180: 2xRL10A: Starliner Boeing OFT: Revision of Atlas V with optional two solid strap-on boosters, and no Centaur 5.4 m payload fairing, but the Starliner spacecraft.
[4] [5] Later in 2014, the US Congress passed a law requiring the US Air Force to "develop a new propulsion system by 2019 to replace the RD-180 engine" that powers Atlas V used by United Launch Alliance (ULA), because the engine is Russian-made, along with the Russian conflict with Crimea. [6] Dynetics is a key partner in development of the ...
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 first launch of a Common Core Booster was the maiden flight of the Atlas V, which was launched from Space Launch Complex 41 at the Cape Canaveral Air Force Station on 21 August 2002. [4] As of November 2020, the Atlas V has made 86 flights, all of which have used a single Common Core Booster.
Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum. RL10 versions were produced for the Centaur upper stage of the Atlas V and the DCSS of the Delta IV. More versions are in development or in use for the Exploration Upper Stage of the Space Launch System and the Centaur V of the Vulcan rocket. [2]
