Interim Cryogenic Propulsion Stage (ICPS)

Giving Orion the big push needed to fly beyond the Moon.

ICPS is a modified Delta IV Heavy Cryogenic Second Stage for NASA's Artemis program.
The stage feeds liquid hydrogen and liquid oxygen to the Aerojet Rocketdyne RL10B-2 main engine to produce 24,750 pounds (110.1 kilo-Newtons) of highly efficient thrust.
ULA is building three ICPS stages for each of the first three Artemis missions to the Moon through a collaborative partnership with Boeing.
NASA's SLS with ICPS is the most powerful rocket ever developed, producing 8.8 million pounds of thrust during liftoff to loft a vehicle weighing nearly six million pounds.
