Rocket configuration finalized with selection of Aerojet Rocketdyne RL10C upper stage propulsion

Orbital ATK (NYSE:OA), a global provider of aerospace and defense technologies, has provided a detailed update on the important progress being made on its Next Generation Launch System, the company said.

The company reaffirmed its commitment to the US Air Force´s Evolved Expendable Launch Vehicle (EELV) program for national security space missions with the announcement of the name of the rocket, OmegA, and the selection of its upper stage propulsion system. As one of the company´s largest strategic investments, OmegA will provide intermediate- to heavy-class launch services for Department of Defense, civil government and commercial customers beginning in three years.

Over the last three years, Orbital ATK and the US Air Force have together invested more than USD 250 million in developing the OmegA rocket, and the company has committed to an even larger additional investment to complete its development and certification. Orbital ATK is already building major propulsion and structural elements with a program workforce of about 500 employees. OmegA is on schedule to complete propulsion system ground tests in 2019 and to conduct its first launch in 2021.
