RL10 Selected for OmegA™ Rocket
"The RL10 has provided reliable upper stage propulsion for more than five decades and we look forward to continuing that legacy with Orbital ATK and its OmegA rocket," said
"The RL10 has an extensive flight history and provides a low-risk, affordable engine with outstanding performance," said
The RL10 burns cryogenic liquid hydrogen and liquid oxygen propellants using a highly-efficient expander engine cycle. With nearly 500 engines flown in space, the RL10 has helped place hundreds of satellites into orbit, sent spacecraft to explore every planet in our solar system and propelled the first human-made object, the Voyager I spacecraft, into interstellar space.
The RL10C-5-1 model that will support the OmegA system is derived from the RL10C-1 that made its inaugural flight in
"Having our RL10 engine selected to provide upper stage propulsion for a fourth launch vehicle reflects the confidence industry places in our product," said Space Business Unit Senior Vice President
