Northrop, Hanwha Explore Solid Rocket Booster for AReS Strike System
Northrop Grumman and Hanwha Aerospace have signed a memorandum of agreement to explore joint development of a solid rocket booster for the Advanced Reactive Strike (AReS) program.
The proposed booster would serve as the first-stage motor for AReS, a surface-launched system designed to deliver long-range strike capability in contested environments.
Early Focus on Propulsion
The agreement marks an initial phase of cooperation, aimed at aligning technical requirements and industrial roles rather than committing to full-scale development.
AReS is being developed as a ground-based, deployable system capable of engaging targets at extended ranges, particularly in areas constrained by advanced air defenses or electronic warfare.
A solid rocket booster is expected to play a key role in achieving the system’s range and rapid response profile.
Northrop Grumman is leading the effort, drawing on its experience in solid rocket motor production across strategic missile and space launch programs.
Growing US-South Korea Defense Ties
The agreement reflects broader momentum in US-South Korea defense cooperation, particularly in missile systems and long-range fires.
Both countries are seeking to strengthen supply chains and scale production as demand rises for precision strike capabilities.
Hanwha has been increasing its footprint in the US market, including through Hanwha Defense USA, while Northrop continues to pursue international partnerships to support capacity and program growth.
The AReS effort also aligns with a wider push by the US and its allies to field stand-off strike systems capable of operating outside the reach of increasingly advanced air defense networks.
No timeline for the AReS program or the booster development has been disclosed.
