Northrop Grumman and Hanwha Aerospace sign MOA to develop first stage solid rocket booster for AReS system

Northrop Grumman and Hanwha Aerospace signed a Memorandum of Agreement (MOA) at the Sea-Air-Space 2026 conference in National Harbor, Maryland, to collaborate on the initial development phase of a first stage solid rocket booster. This component is central to Northrop Grumman's Advanced Reactive Strike (AReS) capability, a surface-launched, extended-range weapon system designed for stand-off strikes in contested and denied environments. The agreement involves key leadership including Northrop Grumman Vice President of Government Programs Ron Boxall and Hanwha Defense USA CEO Michael Coulter.

For Northrop Grumman, this partnership serves as a strategic move to integrate Hanwha's global industrial scale and advanced manufacturing capacity into its high-end missile defense and advanced weapons roadmap. By leveraging the South Korean industrial base, Northrop Grumman aims to optimize the cost-effectiveness and production speed of the AReS propulsion systems, addressing the urgent requirement for rapid deployment of extended-range munitions. This collaboration places Northrop Grumman at the center of a cross-border supply chain designed to counter evolving air and sea threats in the Indo-Pacific and beyond, competing directly with other major defense primes in the long-range precision strike market.

From a manufacturing standpoint, the success of this MOA depends on the seamless integration of propulsion hardware and the ability to scale production of complex solid rocket motor components. Northrop Grumman must now manage the technical synchronization between its system architecture and Hanwha's manufacturing outputs to meet the performance requirements of the AReS platform. The immediate focus will be on the technical feasibility and design validation of the first stage booster during this initial collaboration phase.
