Ambitious Beginnings
In the mid-2010s, Northrop Grumman set its sights on a new endeavor in the rapidly evolving space launch industry. The aerospace and defense giant began developing the OmegA, a rocket designed to launch payloads for the U.S. national security market as well as commercial customers. The project represented a major investment by Northrop Grumman to carve out a position in the increasingly competitive field of space launch services.
The OmegA rocket leveraged Northrop’s extensive experience in solid rocket propulsion. The vehicle’s first and second stages would be powered by large solid rocket motors, building on technology Northrop had developed for the Space Shuttle and other programs. These solid-fueled stages offered simplicity and reliability. For the upper stage, Northrop selected proven RL10 engines burning liquid hydrogen and oxygen. This overall design approach was intended to maximize reliability and performance while controlling costs.
Northrop unveiled its OmegA plans in 2018 as part of the U.S. Air Force’s National Security Space Launch competition. The Air Force was seeking to encourage the development of new vehicles to assure access to space and eliminate reliance on Russian rocket engines. Through this program, Northrop received an initial development award of $792 million to advance the OmegA design and build test hardware.
Overcoming Technical Challenges
As with any new rocket development, the OmegA team faced significant engineering hurdles. Northrop’s facilities in Promontory, Utah served as the epicenter for OmegA development, drawing on the site’s decades of experience in rocket propulsion. Here, engineers grappled with the complexities of building and testing large solid rocket motors.
A critical milestone occurred in May 2019 with the first static fire test of OmegA’s first stage motor. This trial was largely a success, generating approximately 2 million pounds of thrust during a 122-second burn that validated the motor’s design. However, toward the end of the test, the motor’s nozzle exit cone appeared to break apart, sending debris flying. Northrop stressed that the overall test was still successful in demonstrating the motor’s performance, but vowed to investigate the nozzle issue.
Throughout 2019 and into 2020, work progressed on OmegA. Northrop conducted additional tests of the solid rocket motors and began preparing the launch infrastructure at Kennedy Space Center in Florida. The company planned to launch OmegA from the historic LC-39B pad, which required modifications to support the new vehicle. A particularly striking feature was the construction of a mobile launch tower on a platform that had previously been used for Apollo and Shuttle missions.
Shifting Landscape
As the OmegA team pushed forward, the space launch market was rapidly evolving around them. SpaceX, with its partially reusable Falcon 9 and Falcon Heavy rockets, was putting intense pressure on launch prices. Other new vehicles, like Blue Origin’s New Glenn and United Launch Alliance’s Vulcan Centaur, also promised strong capabilities. Northrop bet that OmegA’s conservative design and solid propulsion would offer unique reliability and mission assurance for critical national security payloads.
However, a major blow to the OmegA program came in August 2020, when the U.S. Space Force announced the results of the National Security Space Launch Phase 2 competition. The Space Force selected ULA and SpaceX as the two providers for launches from 2022 to 2027. Northrop’s OmegA was not chosen, with the Space Force noting that ULA and SpaceX offered mature designs at competitive prices.

Project Termination
The loss of the National Security Space Launch contract cast serious doubt on the future of OmegA. Without the guaranteed business and funding from national security missions, the economic case for the rocket was severely weakened. Northrop had previously stated that commercial contracts alone would not be sufficient to justify the investment in OmegA.
In September 2020, just a month after the Space Force decision, Northrop Grumman officially announced the termination of the OmegA program. The company said it would not continue development of the rocket, and that it would not protest the Space Force’s contract decision. Work on OmegA’s launch pad and assembly facilities at Kennedy Space Center came to a halt.
The cancellation of OmegA was a disappointing end to a project that had shown significant promise. Northrop had made substantial progress on the rocket’s development in a relatively short period of time. The large solid rocket motors had performed well in testing, and could have offered a valuable capability for the U.S. launch fleet. However, the realities of the modern launch market, with intense competition and pressure on prices, made it difficult for a new entrant like OmegA to secure a position.
Lasting Impact
While OmegA will not fly, the project still leaves a legacy for Northrop Grumman and the broader space industry. The development of the rocket advanced Northrop’s capabilities in large solid rocket motors, which continue to be important for other applications such as strategic missiles. Northrop has stated that it will apply innovations from the OmegA program to its ongoing work on NASA’s Space Launch System rocket boosters.
The OmegA team’s work at Kennedy Space Center also made a mark. While the pad modifications for OmegA will not be used for that rocket, they remain valuable infrastructure that could potentially support other vehicles in the future. The project demonstrated Northrop’s ability to develop launch facilities and ground systems.
Perhaps most significantly, the story of OmegA underscores the challenges and risks inherent in the modern space launch business. Developing a new rocket is a hugely expensive endeavor with uncertain returns. Established players like SpaceX and ULA have significant advantages in terms of technology, infrastructure, and customer relationships. Breaking into this market is a daunting proposition, even for a company with the scale and history of Northrop Grumman.
Looking to the Future
The cancellation of OmegA does not diminish Northrop Grumman’s importance as a space industry leader. The company remains a major player in satellite manufacturing, space robotics, and other areas. Northrop’s acquisition of Orbital ATK in 2018 significantly expanded its space portfolio, adding launch vehicles like Antares and Minotaur along with the Cygnus cargo spacecraft. The company continues to be a key partner for NASA, the Department of Defense, and commercial satellite operators around the world.
In the evolving space sector, Northrop Grumman will undoubtedly continue to adapt and innovate. While the OmegA project did not achieve its ultimate goal of a new operational rocket, it still represents a bold attempt to push the boundaries of what’s possible. The lessons learned from OmegA will inform Northrop’s future efforts in space technology and launch services.
As the space industry moves forward, it is clear that competition and innovation will only accelerate. New actors are entering the field, from small startups to major tech companies. Established aerospace contractors like Northrop Grumman will be challenged to keep pace and deliver cutting-edge capabilities. The story of OmegA, while ultimately one of an unrealized dream, still reflects the dynamism and risk-taking spirit that define the modern space age.
