NASA Revokes Boeing's Key Contract for Lunar Rocket Component

The U.S. space agency NASA has made a strategic decision that significantly reshapes the supplier map for its flagship lunar program Artemis. According to reports from Bloomberg and Reuters, the agency intends to revoke Boeing's contract for building the advanced upper stage (Exploration Upper Stage - EUS) for the Space Launch System (SLS) rocket and entrust this task to the competing consortium United Launch Alliance (ULA). ULA, a joint venture of Boeing and Lockheed Martin, is to deliver a modified version of the upper stage from its new Vulcan Centaur rocket. This decision, though not yet officially confirmed by NASA, constitutes a serious blow to the image and position of Boeing in a program where it was one of the pillars. The Artemis program, initiated in 2017, is the successor to the legendary Apollo program. Its goal is not only to return humans to the Moon but also to establish a sustained presence, including the creation of the Gateway orbital station and a base on the surface. A key element of this strategy is the super-heavy SLS rocket, whose development has been plagued from the start by massive delays and budget overruns amounting to billions of dollars. The reasons for this radical change are multidimensional. The primary problem NASA faced was continuous delays in the development of the EUS by Boeing. The original upper stage was supposed to enable crewed missions beyond Earth orbit, but its development dragged on, threatening the schedule of subsequent Artemis missions after the planned Artemis III flight, which is to land on the Moon. Facing these challenges, the agency sought a faster and more reliable alternative. The solution turned out to be the Vulcan Centaur design, ULA's new rocket, whose first launch took place in 2023. Its upper stage, Centaur V, is already in an advanced testing phase, giving NASA hope for faster implementation. As Reuters reports, citing its sources, NASA wants to „accelerate the Artemis lunar program”, and utilizing commercially available technology is seen as the way to do it. The new element, sometimes called „Dragon” in NASA's internal nomenclature, is to be used starting with the Artemis IV mission. 4,2 mld USD — Estimated cost of developing the EUS by Boeing The consequences for Boeing are severe. The company, which is the prime contractor for the non-reusable SLS core stage, loses a key element of its involvement in a project of immense prestige. Although it will remain a significant contractor, its role is being downgraded. NASA's decision fits into a broader trend of moving away from the monopoly of traditional giants towards greater competition and commercialization, while strengthening ULA's position. For the Artemis program, this means an attempt to increase the mission tempo, which is to rise from one launch per year to as many as two. „It's fairly remarkable that NASA is taking part of the program away from Boeing, which has been its most important contractor for decades, and giving it to ULA.” — Eric Berger This decision may also have implications for the U.S. defense and space industry, strengthening ULA's position in competition with companies like SpaceX. Ultimately, this move shows NASA's determination to achieve the ambitious goals of the Artemis program, even if it requires painful changes in established relationships with long-term partners.
