The Centaur upper stage uses a pressure-stabilized propellant-tank design and cryogenic propellants. The Centaur stage for Atlas V is stretched 1.7 m (5 ft 7 in) relative to the Atlas IIAS Centaur and is powered by either one or two Aerojet Rocketdyne RL10A-4-2 engines, each engine developing a thrust of 99.2 kN (22,300 lb f).

It was pressure in the tanks that gave the rigidity required for space flight. In order to save weight they were not painted and needed a specially designed oil to prevent rust. This was the original use of WD-40 water displacement oil. [5] The SM-65 Atlas was used as a first stage for satellite launch vehicles for half a century.
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 ...
Falcon Heavy (FH) is a super heavy lift space launch vehicle designed and manufactured by SpaceX. The Falcon Heavy is a variant of the Falcon 9 launch vehicle comprising three Falcon 9 first stages: a reinforced center core, and two additional side boosters. All three boosters are capable of being recovered and reused, although most flights use ...
As of 2023, SpaceX and NASA are the only launch providers which have achieved first-stage reuse of an orbital vehicle with SpaceX’s two-stage Falcon 9 and 2.5-stage Falcon Heavy, and NASA’s Space Shuttle Solid Rocket Boosters. Rocket Lab has recovered multiple first stages of their Electron rocket, but has not flown it again.
Falcon 9 Block 5 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [c] designed and manufactured in the United States by SpaceX. It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust .
