How much can the Delta 4 Heavy Lift?
The Delta IV Heavy can lift 28,370 kg (62,550 lb) to low Earth orbit and 13,810 kg (30,450 lb) to geostationary transfer orbit (GTO). It is an all liquid-fueled launch vehicle, consisting of an upper stage, one main booster and two strap-on boosters.
What engines does Delta IV Heavy use?
Our Role. Main Engine: The Delta IV Medium+ launch vehicles feature an Aerojet Rocketdyne RS-68A booster engine, while the Delta IV Heavy uses three Aerojet Rocketdyne RS-68A engines, one on each of its three common booster cores.

How much lox does a Falcon 9 have?
Though it varies per mission, a typical Falcon 9 flight can use about 40,000 gallons of LOX in the first stage and several thousand more in the rocket’s second stage.
Is the Delta IV Heavy human rated?
Delta IV H first- and second-stage engines can be human- rated. For most HR Delta IV design options studied, the payload performance to the ISS and lunar target orbits provides significant positive margin with respect to Ares I ISS and lunar gross performance.
What is the Delta IV Heavy made of?
The Delta IV Heavy is currently the most powerful rocket in ULA’s fleet. Fueled by 465,000 gallons (1.76 million liters) of superchilled liquid hydrogen and liquid oxygen, the mega launcher consists of three common core boosters that generate more than 2 million pounds of thrust.
Is the Delta IV heavy human rated?
What is the difference between Falcon Heavy and Delta IV Heavy?
For starters, both rockets are extremely heavy, but Falcon Heavy is just about double the weight of Delta IV Heavy, clocking in at 3,132,301 lb. (1,420,788 kg) and 1,616,000 lb. (733,000 kg) respectively.
How much can the Falcon Heavy Lift?
With the ability to lift into orbit nearly 64 metric tons (141,000 lb) Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy.
How powerful is the Falcon Heavy rocket?
With more than 5 million pounds of thrust at liftoff, Falcon Heavy is the most capable rocket flying. By comparison, the liftoff thrust of the Falcon Heavy equals approximately eighteen 747 aircraft at full power.
What is the difference between SpaceX’s Delta IV Heavy and Delta IV?
For its final stage, it makes use of the Merlin 1D-Vacuum, which Elon Musk said can generate 80 tons of thrust. Delta IV Heavy, on the other hand, utilizes far fewer engines during takeoff. These include the RS-68A engine for its first stage and the RL10-B-2 for its second stage.
